TIA TR 42.1 (Commercial Building Cabling)
and TIA TR 42.7 (Copper Cabling Systems)
Mesa, AZ, February 3–5, 2009
The TIA TR 42.1 (Commercial Building Cabling)
Subcommittee has developed the updates to the wellknown TIA 568 series of standards—568-C.0 and
568-C.1—for generic information and for commercial
building telecommunications cabling (minimal requirements for telecom cabling systems within commercial
buildings), which have been approved and soon to be
for sale (now buy 568-B.1). The TIA TR 42.7 (Copper
Cabling Systems) Subcommittee is responsible for the
also well-known TIA 568 B.2 Standard for the user
and manufacturer to follow for copper hardware specs
and performance. During this first group of meetings
in 2009, discussion covered the status of TIA 568-C.2
for Balanced Twisted-Pair Cabling Components, which
was still likely to be published after October. They also
covered the Data Center standard (TIA-942), the
Building Automation Standard (TIA-862), a new
standard for Health Care Facilities, the Outside Plant
standard (TIA-758), the MICE Tutorial (TSB 185),
the new field tester standard
(TIA 1152), the TSB for current capacity over UTP
(TSB 184), and the revision of TSB 155 for 10 gigabit
Ethernet over Category 6 cabling.

2. TIA 568-C.1 (Commercial Building
Cabling) Status
➣ ACTION: After final editorial changes are made,
TIA 568-C.1 “Commercial Building Telecommunications Cabling Standard” will be available from IHS.
What You Need to Know
To purchase, visit the IHS website at http://store.ihs.com
and enter the standard’s identifier (TIA 568-C.0 or C.1)
or go to www.tiaonline.org and search for a standard
and place your order through TIA with IHS.
3. TIA 568-C.2 (Copper Cabling
Components) Ballot Comment Review
Any contributions meant for this standard will be reviewed at the TR 42.7 Interim Meeting, May 2009.
Subcommittee members will be requested to confirm
that the proposed changes are “editorial” and corrections as appropriate would be made to the current
draft, in preparation for publication.
➣ ACTION: Publication of TIA 568-C.2 “Copper
Cabling Components” is expected after October 2009.
What You Need to Know
Follow the progress of TIA 568-C.2 to see if it’s available
for sale through IHS before the end of 2009.
4. TIA 942 (Additional Media and Guidelines
for Data Centers) Ballot Comment Review
Issue: Since this document also describes temperature and humidity requirements, media, etc., make
the title more broad.
Resolution: Would retitle TIA 942, Addendum 2 as
“Additional Guidelines for Data Centers.”
Issue: The Table titled “Revised temperature and humidity requirements for telecommunication spaces”
is being revised for the Pathways and Spaces updated
standard. What should you show here if it’s really
not completed yet?
Resolution: They would retain the table’s information that only pertains to the data center for now.
(See illustration on page four for the data center
information.)

5. TIA 862 (Building Automation Systems)
Ballot Comment Review
A “mock” ballot had been issued and reviewed and
comments resolved. Many changes were made to be
consistent with terminology as used in 568-C.0 and
C.1 and to properly reference current standards
Issue: This is a generic document, make it look that
way.
Resolution: Since its title now is “Building Automation Systems Cabling Standard for Commercial
Buildings,” remove “for Commercial Buildings.”
Issue: Does “Coverage Area” remain in this document as a legitimate space?
Resolution: Yes, because it is specific to the BAS
cabling infrastructure.
Issue: Don’t confuse a work area with a work station.
One is a cubicle area and the other is a computer.
Resolution: Show by definition that the work area is
a building space where the occupants interact with
telecommunications terminal equipment. This has
nothing to do with a “work station.”
Issue: Make sure people understand we are talking
about centralized cabling for BAS and not a centralized BAS system.
Resolution: Rename Section 3.3 Centralized BAS
Cabling.
©
2009 Business Communication Services
Issue: Include the telecommunications enclosure under the section for backbone cabling.
Resolution: Section 4.1 (General) would add telecommunications enclosures (TE’s) to the list of interconnections (such as for the telecommunications
room, the common telecommunications room, the
equipment room, etc.).
Issue: When describing where a Zone Box can go,
remember it can also be placed in the floor.
Resolution: Change text to state that the Zone Box
shall be located in a fully accessible, permanent location, such as a building column, a floor or a permanent wall, and should be provided with appropriate
security.
Issue: There are more mounting options for a Zone
Box than are mentioned in this draft.
Resolution: They would rewrite Section 6.4.5 titled
“Plywood Backboards” and call it “Mounting Methods” and state that a variety of methods can be used
including: metal perforated panel, plywood backboard or EIA-310-E compliant mounting. These
may be located in the back or side of the interior
portion of the box.
Issue: Regarding grounding and bonding of the zone
box, remind the reader to comply with the requirements in the TIA grounding and bonding standard
ANSI-J-STD-607-A.
Cabling Standards • Telecommunications Industries Association
Resolution: The grounding and bonding section
would be rewritten to state that if the Zone Box
includes metallic components, the grounding shall
meet the requirements and practices of applicable
authorities or codes. In addition, the telecommunications grounding/bonding system shall conform to
ANSI-J-STD-607-A requirements.
Issue: Since bundled cabling requirements are different than requirements for individual 4-pair cabling,
tell people.
Resolution: Refer to proposed TIA TSB-184 for current capacity of bundled cabling. Bundled cabling
requirements are different than individual 4-pair
cabling requirements.
➣ ACTION: The update to TIA-862 (BAS Cabling)
would go out for its first internal 30-day ballot.
6. TIA 568-C.1, Addendum 1 (Temperature
Limits) Status
➣ ACTION: An Addendum would be created to
TIA 568-C.1 for pathways and spaces specific to
commercial buildings. No timeline information
given yet.
What You Need to Know
No due date information for this new Addendum has
been given out yet.
7. Energy Efficiency
IEEE 802.3 acknowledged TR 42’s support of “green
initiatives” and replied that they were working on
this issue by developing energy efficient PHY’s and
applications that work over TIA specified cabling.
➣ ACTIONS:
1. A “green initiative” paragraph was recommended for inclusion in the foreword of future
TR-42 standards (see TR 42.3 section for text).
2. TIA would share any progress on the development of energy-efficient cabling specs with
IEEE.
8. TIA 758-A (Outside Plant) Status
It was discussed that this standard should now become common to all others. This would result in a
change to the figures in TIA 568-C.0 and C.1 and
hopefully, an editorial change would get in before
both documents were published.
5
What You Need to Know
The new Figure 1 would be changed to reflect the
change to showing TIA 758-A as a common standard
as opposed to being under the premises standards.
The illustration on page 6 shows you where 758-A has
moved.
9. TSB 185 (Mice Tutorial) Status
The task group was still waiting for international
documents to review.
➣ ACTION: The next meeting should be able to
prepare a Default, MICE TSB.
10. TSB 184 (Current Capacity) Status
A couple comments to be on the Default
Ballot:
Issue: You need to strengthen this standard by including a reference and also indicate that Category
5e cabling is the minimum requirement.
Resolution: Change text to say that remote powering should be implemented using Category 5e or
better 4-pair balanced twisted-pair cabling as specified in ANSI/TIA-568-C.2.
Issue: In the Annex A list of “Considerations for
current capacity of category types and installation
conditions—Temperature Rise Considerations,” be
specific about whether “heat transfer” is a significant
parameter.
Resolution: Added the entry “Improved heat transfer coefficient between materials” to the list.
➣ ACTION: A 30-day Default ballot was agreed to
for the technical changes made. Draft 4.0 would be
created and posted to TIA’s ftp site.
11. TIA 1152 (Field Testers) Status
The group reviewed all ballot comments and made
appropriate technical changes. Other than some
definition additions and reference corrections, here
are some of the technical changes:
Issue: Combine the Introduction and Scope into a
new Scope to be clearer.
➣ ACTION: Figure 1 in TIA 568-C.0 and C.1
would be editorially changed to reflect the “common” placement of TIA 758-A for Outside Plant.

Issue: Explain more clearly, the performance parameters for Level IIe testers.
Resolution: Say that “Level IIe field testers shall
conform to the requirements in the Table for Measurement Requirements for Level IIe Testers for the
baseline, permanent link, and channel test configurations. The channel accuracy performance parameters
include the effects of the modular jack mating of the
test instrument with the local end of the user patch
cord. Methods to verify compliance of field tester requirements are specified in clause 4.5 (Procedures for
testing field tester parameters).”
Resolution: The Standard’s Scope would read:
“This Standard includes requirements for field test
instruments that are used to test balanced twistedpair cabling as specified in the ANSI/TIA-568-C
series of structured cabling standards. This Standard
specifies the reporting and accuracy performance
requirements of field testers for balanced twisted-pair
cabling measurements. Level IIe, III, and IIIe field
tester requirements are also specified in this Standard. This Standard contains methods to compare
the field instrument measurements against laboratory equipment measurements specified in ANSI/
TIA-568-C.2. Measurement accuracy based upon
the assumptions for key performance parameters is
addressed.”
Issue: Explain more clearly, the performance parameters for Level III testers.
Resolution: Say that “Level III field testers shall
conform to the requirements in the Table for Measurement Requirements for Level III Testers for the
baseline, permanent link, and channel test configurations. The channel accuracy performance parameters
include the effects of the modular jack mating of the
test instrument with the local end of the user patch
cord. Methods to verify compliance of field tester requirements are specified in clause 4.5 (Procedures for
testing field tester parameters).”
Issue: Correct where the permanent link and channel information actually resides.
Resolution: This would be changed from
TIA 568-C.0 to TIA 568-C.2.
Issue: Since there is no information about testing
anything less than Category 5e cabling, explain.
Resolution: Change the text to say that a Level IIe
tester is suitable to test up to and including Category
5e cabling.
Issue: Do the same thing for Category 6 and 6A
testing.
Resolution: Change the text to say that a Level III tester is suitable to test up to and including Category 6
cabling and that a Level IIIe tester is suitable to test
up to and including Category 6A cabling.

➣ ACTIONS:
ments for Coax Cabling,” was published 1/22/09.
This standard should now:
1. Encompass the coax cable that has been
“blessed” by cable and satellite people.
2. Be very relevant regarding the change to digital
service where users may have to run new cable.
3. Set a new kind of benchmark with coax for
high-speed digital applications.

2. TIA 570-B Status
➣ ACTION: TIA 570-B was reaffirmed by the subcommittee and any revision/update to TIA 570-B
would be delayed until TIA 569-C was finished.
What You Need to Know
In the meantime, reaffirmation of TIA 570-B would go
out to TIA members, following the appropriate policy.
Members noted that this standard still needed to be
strengthened and there was a suggestion to work
closely with SCTE. If necessary, a press release could
be sent out announcing the reworking of 570-B to elicit
more input.

Discussion
• Create a “generic” coaxial cabling standard—like a
568-C.4 for broadband coax cabling.
• Every hospital has coax and it can’t be ignored.
• Remember that the cable used has to be “plenum
rated.”
➣ ACTION: This concept was introduced at the
Plenary and it was agreed that the idea of creating
a standard for “generic” coaxial cabling would be
reviewed by the TR 42.7 (copper cabling components) group for later incorporation into 568-C.2.
This would be discussed again at the October 2009
Plenary meeting.

Telecommunications infrastructure affects raw material consumption. The infrastructure design and
installation methods also influence product life and
sustainability of electronic equipment life cycling.
These aspects of telecommunications infrastructure
impact our environment. Since building life cycles
are typically planned for decades, technological
electronic equipment upgrades are necessary. The
telecommunications infrastructure design and installation process magnifies the need for sustainable
infrastructures with respect to building life, electronic equipment life cycling and considerations of
effects on environmental waste. Telecommunications
designers are encouraged to research local building
practices for a sustainable environment and conservation of fossil fuels as part of the design process.
➣ ACTION: This statement was incorporated into

2. CITG (Cabling Implementation Task
Group) Liaison Report
ISO/IEC and the CITG were planning the final
CD (Committee Draft) to be ready for their
March IEC meeting.
Discussion
• The group wanted to adopt TIA’s Identifier markings from TIA-606-A.
• Some annexes still needing to be finished:
- Infrastructure complexity classification
- Pair-pin configuration and optical polarity
- Data Centers
- Industrial
- Residential
• Some annexes up for review next meeting:
- Multi-tenant premises
- Office premises
- Space allocation for functional elements
➣ ACTION: The CITG had agreed to adopt TIA’s
606-A identifiers.
3. Changes to TIA 569-B, Addendum 1
“Temperature and Humidity Requirements
for Telecommunications Spaces”
The major changes resulting from the ballot comment review were:
Issue: Since this Addendum was for “revised” temperature and humidity requirements for telecommunications spaces, be correct.
Resolution: See table on Page 13 that reflects all
changes to ASHRAE requirements.
Issue: Make the method of measuring ambient temperature and humidity more practical.
Resolution: Paragraph rewritten as: “Temperature
and humidity should be measured at air intakes of
operating (powered) equipment and, except in telecommunications enclosures, at a distance of 1.5m
(5 ft) above the floor level every 3 to 9m (10 to 30
ft) along the center line of the aisles at the front of
the cabinets or racks. In telecommunications enclosures the temperature and humidity should be
measured as near as practical to the center of the
enclosure.”
➣ ACTION: TIA 569-B.1 to go out for a Default
Ballot, since technical changes were made.
569-C.
Volume 01-09
12
Cabling Standards • Telecommunications Industries Association
What You Need to Know
This will go out to a Default ballot (30 days) and it
could be finalized in August and for installations to be
“standards compliant,” its requirements will need to be
followed.
4. Changes to TIA 1005, Addendum 1
“Industrial Pathways and Spaces”
Issue: When talking about the Industrial Equipment
Room, say the same as TIA 569-B.1, which is the
current environmental spec for industrial spaces.
Resolution: They would correct the paragraph on
HVAC for the Industrial Equipment room to say
that “a mechanism to remove the generated heat
shall be included to avoid any detrimental effect to
the active equipment.” And that they “…refer to the
active manufacturer for specific guidance on temperature and humidity limitations.”
Issue: Correct pathway separation for EMI sources…it’s not “0.”
Resolution: They would correct separation to match
section 5.2.3 for separation from lighting to five
inches from fluorescent lighting.
Issue: When talking about what benefits there are to
where a telecom enclosure is located, clear up what
kind of cabling it can help. (We know that cable being routed to the TE is considered backbone cabling,
and cable being routed from the TE is considered
“horizontal cabling”.)
Resolution: Change one of the reasons it can help to
minimize horizontal cabling length.
Issue: Be clear that these are the same as ASHRAE
recommendations for heating and air conditioning.
Resolution: Under the HVAC section for the telecommunications enclosure use the ASHRAE recommendations:
Temperature and humidity inside the telecommunications enclosure shall be maintained as follows:
1. Temperature: 5 – 40º C (41 – 104º F) dry
bulb.
Reduce maximum dry-bulb temperature 1º C /
300m (1.8º F/1000 ft) above 900 m (3000 ft)
altitude.
Minimum temperature with diskette in a drive
is 10º C (50º F);
2. Relative Humidity: 8 - 80%; and
3. Maximum dew point: 28º C (82º F).
The group essentially had to work on matching their
HVAC requirements with ASHRAE’s to make this
standard correct.
See illustration on page 13.

➣ ACTION: TIA 1005-1 would go out for another
SP (full industry) ballot and be handed over to 42.9
to check ballot comment resolution.
What You Need to Know
Remember, they will recommend this goes to be published when TIA-1005 (out of 42.9) is available.
5. TIA 569-C (3rd revision) Update Plan
The update plan used:
• Recommendations of the Conduit Fill Task Group.
• BAS commercial building content placed in annexes.
• Access provider spaces, service provider spaces,
common equipment rooms, common telecommunications rooms, MUTOA’s and CP’s considered
generic.
• “Green Initiative” or Stewardship text in foreword.
• No commercial building terms.
BAS annex was removed and forwarded to TR-42.1
for inclusion in TIA-862-A.
➣ ACTION: After the update plan had been
explained, the writing of the 3rd revision of
TIA 569 (C) was approved.
What You Need to Know
New actions agreed to were:
1. There would be no informative Annex on Conduit
Fill.
2. Content specific to BAS cabling would be removed.
3. Content specific to commercial buildings would be
removed.

5. Schedules would be developed that would allow
569-C and 569-B.1 to be published at the same
time.
6. Commercial building HVAC requirements used
would be used as “default” HVAC requirements for
generic spaces.
7. Verify whether the temperature for the telecom
enclosure is with or without active equipment.
8. TIA 568-C.0 would be referenced for the MICE
table.
9. Pathway separation requirements for E2 and E3
electrical environments would be included.

Next Plenary Meeting
1. ISO/IEC’s WG3 Technical Report on
Identifiers
Discussion
• ISO/IEC WG3 has a draft document that draws
heavily on our strawman 606-B without the
legacy identifiers. The technical Report is SC
25N1612.
• Our subcommittee Chair is also the editor of
this ISO document.
• Was it realistic for the U.S. and ISO to be the
same or should we come close to understanding
their system and merge that into our U.S. document?
• It would be great if a couple of years from now
the nomenclature was the same.
• It would make sense to have a company’s administrator be able to administer their company
worldwide. One command center could do it all.
• This was an opportunity for us to step to the
forefront internationally.
15
➣ ACTIONS:
1. Vote on the updated TIA 606 as a US position
and get comments from our experts and submit along with our doc to US TAG.
2. Via conference call resolve comments and
compile all and post on the TIA website.
More Discussion
• When the CITG adopts their document, base our
identifier portion of TIA 606-B on CITG’s and
then decide if we want to finalize 606-B or wait
more to see what ISO/IEC does.
• We are only waiting for this Identifier product and
not yet doing anything with 606-B yet.
• Our goal should be to have only part of 606-B the
same as the ISO/IEC (international) standard.
3. TIA Symbols
Discussion
• Compile all the symbols in TIA 606 now and send
them to the Definitions Committee, TR 42.5
• TR 42.5 would keep up with the symbols.
• TIA 606-B would be the only published document that showed the symbols.
➣ ACTION: Send all our symbols in TIA 606 to
the Definitions Subcommittee, TR 42.5, for review
and finalization.

➣ ACTION: The Subcommittee would provide
comments on the ISO/IEC document on Identifiers
(TR 14763-2-1) via the U.S. TAG and would defer
action on TIA 606-B until ISO/IEC’s document was
completed.
2. Development of TIA 606-B
Discussion
• Existing shalls and shoulds would be included.
• Industrial identifiers would be included.
• Now we should incorporate all our comments into
a single TIA 606 position and give that to the U.S.
TAG to deliver to ISO/IEC.

Optical Fiber Cabling
Mesa, AZ, February 3, 2009
The TIA TR 42.8 committee for “Telecommunications
Optical Fiber Cabling Systems,” provides research, testing, and presentations on optical fiber being used in performance standards. This committee has now developed
the TIA-568-C.3 standard, “Optical Fiber Cabling
Components” which is an update to 568-B.3 published
in April 2000. This first meeting of 2009 discussed
TIA 568-C.3, the new “Optical Fiber Cabling” standard, and what was going on with OM4 fiber.
86.5.1 Optical lane assignments for 40GBASE-SR4
The four transmit and four receive optical lanes of
40GBASE-SR4 shall occupy the positions depicted
in Figure 86-3 when looking into the MDI receptacle with the connector keyway feature on top. The
interface contains eight active lanes within 12 total
positions. The transmit optical lanes occupy the leftmost four positions. The receive optical lanes occupy
the rightmost four positions. The four center positions are unused. …

An update on the IEEE acceptance of the pin-out
variants for 40 Gbps and 100 Gbps parallel optics
using the MPO connector was presented:
• IEEE creating 40 and 100 Gig Ethernet applications.
• Currently, IEEE included a clause that said the optical signals that resided in the transceiver were…
(This was left blank because it was undefined.)
• If no contribution was brought in, this would be
left undefined and therefore there would not be a
completed interoperable standard.
• A contribution had been brought in for Clause
86.5.1 with pin assignments for both speeds that
was accepted by IEEE 802.3ba, with minor modifications.

TIA TR 42.9
Industrial Building Cabling
Mesa, AZ, February 4, 2009
The TR 42.9 subcommittee is developing the TIA
1005 standard for the industrial telecommunications
infrastructure. This brought in new effects from noise,
dust, distance, vibration, EMI, etc. This standard refers
to cabling for industrial manufacturing—on the factory floor. During this first Plenary meeting of 2009,
the subcommittee covered an ODVA (Open DeviceNet
Vendor’s Association) update that shows the work they’re
doing on industrial standards, the work done by the
POF Task Group before this meeting, and what the
next update of TIA-1005 could cover.

ODVA Industrial Work
1mm POF Task Group Input
TIA 1005 Update Plan
Next Plenary Meeting
1. ODVA Industrial Work
Update
• ODVA published their technical standard twice/
year.
• The November 2008 standard supported POF
(Plastic Optical Fiber) for 10/100 Mbps networks.
It included connector-less transceivers. Still POF
didn’t go a long distance.
• They were working on Grounding and Bonding
for industrial.
• A JSIG (Joint Special Interest Group) had released
a MICE report.
• A JSIG was working on the third revision of its
Planning and Installation Manual—to be completed in 2009.
• Ethernet was being adopted for additional field
buses under IEC; release of document expected
2010.
• After above release, they were to begin Edition III.
• See SC65/JWG10 list of networks they support.
2. 1mm POF Task Group Input
Update
• The Task Group was still in effect even though
1mmPOF was removed from TIA-1005.
• There could be a technology update for next revision of 1005.
• ISO/IEC 60793 supports POF for 100 MHz over
100 meters. (This was taken out of TIA 1005 because there were no test procedures, etc.)
©
2009 Business Communication Services
• This Task Group was continuing to monitor standards for 1mm POF adds/changes and would prepare a proposal for 1mm POF for TIA 1005 (to
include pulling tension, bend radius, testing, etc.).
• This work will be kept in this TR 42.9 group.
• What is different now is that distance is different
and perhaps 65 meters would work in the industrial (versus commercial) environment.
• Industrial needs to decide whether POF is acceptable to TIA 568-C.0. If Industrial wants to add
this as a media, they would need to do some more
work. The Task Group seemed to be going down
that path.
• ISO/IEC has information on A4a and A4d POF.
• What had happened to make this more viable
was that MOST (the Media Oriented Systems
Transport protocol from Europe) used Ethernet
and when POF for the lower bandwidth was developed, that led to the higher bandwidth over
POF. This was pushed by Europe—a technology
changed.
➣ ACTION: TR 42.9 would start working on POF
for 568-C.3 with the POF Task Group.
3. TIA 1005 Update Plan
Update
• TIA-1005 would remain a TIA 1005 standard
(not a new 568 series such as D).
• Since 568- C.0 and C.1 had been approved for
publication and would soon be stabilized, it was
proposed TR 42.9 open up a new PAR (project)
and decide what to do:
• Update the standard with the inclusion of AD1 for
Pathways and Spaces.
• Update with new emerging technologies (POF,
etc.)
• Include other emerging topologies for Ethernet
which affect the way the network is looked at. Instead of having a switch outside, the device would
be inside with daisy chaining to other devices
where switches are inside). This is simply making
the switch smaller (less ports) and it is embedded
in the hardware. Everything is distributed. We
still could make use of the generic structure to get
from point A to point B.
• These were just a few things they wanted to look
at…whether they were adopted or not.
➣ ACTION: The revision project was approved
unanimously.
Cabling Standards • Telecommunications Industries Association
19
What You Need to Know
The Scope of this approved revision project, as approved for ANSI/TIA-1005:
1. Combine Addendum 1, Industrial Pathways and
Spaces (TIA 1005-A-1) into 1005.
2. Align with generic structure of the TIA 568-C series.
3. Incorporate any new technology that was not in the
previous release.
This was all to be reviewed at the August 2009 Plenary
meeting with a final document to be ready for review at
the November 2009 Plenary meeting.
➣ ACTION: It was estimated that the ballot would
be sent to the formulating group by December 2009.

➣ ACTION: The section of Testing and Verification
would be drafted and discussed via conference call.
2. 607-B Design Content
3. Ground Busbar Investigation
a. To be used in other countries, the group decided to write this for a busbar with a minimum of 80% copper. (This would open it up
to other alloys with at least 80% copper.)
b. A proposal was made to include a mechanical
connection (revolutionary for America).
c. The 2" busbar was considered because you
could
• Make an effective electrical connection
with it.
• Use it for performance monitoring.
• Use it for an interface for each end point.
d. There still was the issue that the international
standard did not require a mesh network.
➣ ACTION: This subject was left undecided as to
any size busbar.
4. EMC Annex
Presentation
a. The group was advised to use balanced twistedpair cabling to reduce EMI (electromagnetic
interference).
b. The ultimate objective was to reduce noise.
Discussion
This would involve information as in NECA/BISCI
607. It would cover:
• Computer room
• Cabinets and racks
• Equipment in cabinets and racks
• Cable ladders, cable runways, conduit, pipes, and
building steel
• The mesh-bonding network
• Bonding conductors for connections to the meshBN or RGB
• Telecommunications equipment bonding connector (TEBC)
• Separation
• Bonding equipment cabinets/equipment racks to
the TEBC
• Structural bonding of equipment cabinets/equipment racks

this and get a draft ready for the next Plenary meeting, August 2009.
5. Term: MESH-BN
➣ ACTION: A Task Force would propose new
terms and explain their relationship with other
known terms.
What You Need to Know
The term SBG (Supplementary Bonding Grid) was
brought up as that being generally placed under a
raised metal floor or above the racks/cabinets complex to a supplementary function to the serving power
circuit’s equipment grounding protector... and they considered renaming that the “Mesh-BN” but had problems
because the MeshBN did not include Star grounding
and IBDN. They needed somehow to point out that the
MeshBN was not the only bonding network.
“MESH-BN” is the correct terminology. The objective of the Task Group was to recommend a new section just for Mesh-BN and then to include all types.

Cabling Standards • Telecommunications Industries Association
IEEE 802
IEEE, the Institute of Electrical and Electronics Engineers, Inc., is a not-for-profit association that publishes
technical documents, holds conferences, and develops
standards. IEEE 802 is the LAN/MAN Standards
Committee for Layers 1 and 2 of the OSI (Open System
Interconnection) reference model.
Layer 1 is the physical layer (hardware including cabling) that applies to the LAN (Local Area Network)
defined as a campus, and MAN (Metropolitan Area
Network) for intracity networking. Light or radio signals are conveyed through the network at the electrical
and mechanical level. It consists of the electromagnetic
and physical aspects of a device, a transmission medium
(the cable), and the interface between them (connectors
or NICs [network interface cards]). The PHY refers
to anything relating to hardware (cables, connectors,
cards) that is enabled to send and receive data.
Layer 2 is the Data Link Layer where data packets become bits and carry transmission protocol information
to 1) handle errors in the physical layer; 2) provide flow
control, and 3) provide frame synchronization. This
data link layer is made up of two sublayers—the Media Access Control (MAC) layer and the Logical Link
Control (LLC) layer. That MAC sublayer controls how
we access data and gives permission for its transmission.
The LLC layer controls frame synchronization, flow
control and error checking.
The other five layers of the OSI model are Layer 3, the
Network Layer (where switching and routing is provided
and logical paths [virtual circuits] are created that send
data from node to node); Layer 4, the Transport Layer
(where data is transferred [transparently] between systems/hosts and end-to-end error recovery and flow control
is performed); Layer 5, the Session Layer (where connections between applications are managed); Layer 6, the
Presentation Layer (where data is transformed into the
form that the application layer can accept when that
data is different;) and, Layer 7, the Application Layer
(where application and end-user processes are supported—everything at this layer is application specific).
IEEE 802.3—Ethernet
IEEE 802.3 is referred to as the Ethernet standard (an
application). This includes projects for 1 gigabit Ethernet transmission (1000 Mbps) over both fiber (802.3z1998) and copper (802.3ab-1999). The standard for
DTE Power over Ethernet (802.3af-2003) has been
completed and published; so has Ethernet in the First
Mile (802.3ah-2004); the standard for 10 gigabit Ethernet over coaxial cable (802.3ak-2004), and the standard for 10 gigabit Ethernet over fiber (802.3ae-2003).

2009 Business Communication Services
Committee work continues with the Power over Ethernet Plus Task Force (802.3at) who have now settled on
a slightly higher minimum capability than 24 watts,
the Energy Efficient Task Force (802.3az) finding ways
to reduce energy, the 10 Gigabits per second EPON
group (802.3av) and, there is a Higher Speed Study
Group (802.3ba) that is studying 40 Gbps and 100
Gbps over fiber and copper.
Current Phy-Related Work Items
802.3at Power over the Ethernet Plus Task
Force
The IEEE 802.3 working group has formed this Higher
Speed Task Force to evaluate the requirements for the next
generation of Ethernet technology at 40 and 100 Gbps.
Status
• The current first round of sponsor ballots are closing and they are hoping for ratification in September 2009.
• There have been no real technical changes except
the 24 watt minimum objective now has a real
value that works out to 25.5 watts (which beats
the objective).
802.3az The Energy Efficient Task Force
This Task Force work is to extend the number of applications that could benefit from more power being
delivered over Ethernet.
Goals
• Reducing power during low-link utilization
• Remain compatible with existing cabling infrastructure
Target PHYs
• 100BASE-TX (Full Duplex) (Fast Ethernet)
• 1000BASE-T (Full Duplex) (Gigabit Ethernet)
• 10GBASE-T (10 Gigabit Ethernet)
• 1000BASE-KX (1 Gigabit backplane, added in
July 2008)
• 10GBASE-KR (10 Gbps serial backplane
connectivity)
• 10GBASE-KX4 (10 Gbps over 4 lanes for
backplane connectivity)
Discussion
• Optical PMDs were not included and there was
no particular reason except that a proposal was not
brought in in time to change the project authorization request.
Cabling Standards • Telecommunications Industries Association
• There was a growing interest in low power idle for
optical PMDs, but that would need to be a new
project.
• Copper PMDs represented a broad market potential, which is one of the criteria needed to get a
project started in 802.3.
• The data center (still copper with shorter distances) did not use auto-negotiation to manage
its power. It was used to advertise low power idle
capabilities, but not to “manage” power.
Status
• They were reviewing comments to Draft 1.2.1 and
Draft 1.3 would be ready for review in April 2009.
• 802.3az was expected to be approved in September
2010 (this slipped due to additional work required
to get backplane Ethernet ballot-ready, as well as
several unspecified values that were remaining.)
802.3av 10Gbps EPON (Ethernet Passive
Optical Network) Task Force
This is to support subscriber access networks using
point-to-multipoint topologies on optical fiber.

802.3ba Higher Speed Ethernet Task Force
The IEEE 802.3 working group has formed the Higher
Speed Task Force to evaluate the requirements for the
next generation of Ethernet technology at 40 and
100 Gbps.
Status
• Draft 1.2 was available as of February 10, 2009.
• Approval of standard expected in June 2010.
• This new standard’s goal is to:
1. Provide Physical Layer specifications which
support 40 Gb/s operation over:
- at least 10km on SMF
- at least 100m on OM3 MMF
- at least 10m over a copper cable assembly
- at least 1m over a backplane
2. Provide Physical Layer specifications which
support 100 Gb/s operation over:
- at least 40km on SMF
- at least 10km on SMF
- at least 100m on OM3 MMF
- at least 10m over a copper cable assembly
■
Status
• The Task Force was currently working on development of the next-generation, 10 Gbit/s capable
Ethernet Passive Optical Network (10G EPON)
specifications, anticipated to bring a new flavor of
PON technology to life by 2009. This would be
applicable in multiple environments to support
bandwidth-intensive applications that would require fast, reliable, scalable, first-mile connections.
Such applications included Broadcast TV (expanded HDTV content), IPTV, time-shifted TV, rich
unicast based VOD (Voice on Demand) content
libraries, 3D Online Interactive Games, UltraHigh
SpeedInternet, Personal Video Casting, and many
more applications.
• Draft 3 of this application standard, released
1/16/2009, was in its ballot process.
• The last technical changes had been made and
it was planned to go to RevCom (the Standards
Board Review Committee) in July with the expectation that the standard would be approved in
September 2009.
