Fan Unit
The fan unit BFD 509 13/1 is used, in order to implement the
principle of parallel cooling. That is in the cabinet the cooling air is
taken in at the front and is exhausted in the reserved air chimney
area at the back of the cabinet. The nominal depth of the air
chimney is ~ 100 mm.
Figure 3-4 - Parallel cooling
A rear plate is mounted 100 mm from the back of the cabinet to
secure a chimney so that pressure rise in the chimney can’t cause
heated air to be forced in to the above or below equipment the
wrong way.

Connection and Conversion Field, CCF
The CCF, BMF 904 10, is a cabinet mounted filter intended for
connection of external 2Mb/s E1 links with 75 ohms or 120 ohms
impedance.
The CCF is connected to the AUS-C by means of 100 ohms pair
cable, supplied with 10-pin Metral connector. The external side of
CCF is connected to DDF by means of 75 ohms coax cables or
120 ohms pair cables, supplied with 24 pin Sofix connectors.
The CCF includes parallel connection of dedicated pins between
in– and output connections, for testing of analogue subscriber
lines. Several nodes can therefore be connected in parallel to one
test unit without damping and impedance conversion of the test
signal.

Cabinet Installation
This instruction for wall mounting of cabinet BYB 502, defines what
steps have to be taken to ensure secure mounting of fully equipped
cabinet modules to a wall structure. The initial wall strength testing
operations are required to accurately obtain the wall strength value.
This value is converted in table 2 to the recommended rail
mounting torque. A drilling template is included with the cabinet
packing, and shall be used to achieve correct positioning of the
mounting holes.
Wall mounting kits, 18/BYB 502/1 includes all the parts required for
mounting one cabinet on a wall. Additional plugs & screws and
expanders are included for wall strength testing. General wall
mounting applications require the plug &screw solution for
mounting of rails. The supplied expanders should only be used
when seismic compliance is required.
All dimensions and tolerances are given in mm.
All tightening torques are given in Nm.
4.1
Validation
To ensure that wall mounted support assemblies for BYB 502 will
securely maintain accurate suspension of fully equipped cabinet
units, the installation application must comply with the following
sections:
1. All operation activities in the mounting instruction 1531-1/BYB
502 140/200 must be followed, and fulfils defined acceptance
criteria.
2. Wall mounting kits 18/BYB 502/1 must be used. None of the
supplied parts may be replaced by other similar products.

Mounting of rails
4.2.1
Marking of mounting holes
Marking of the hole patterns on the wall may be performed
manually, or by using the supplied drilling template.
Brick wall:
Nail the template to the wall by using small nails.
Concrete wall:
Fix the template to the wall by using strong adhesive cello tape.
Check alignment with horizontal and vertical levels, by using a
water level or a plummet.
Figure 4-1 - Hole pattern for short rails
Drill guide holes with a 3-6 mm drill-bit through the markings 1, 3, 7
and 9. The guide holes should be drilled to a depth of 10-20 mm.
4.2.2
Choice of fasteners
The use of correct fasteners for fixing of rails on various wall
structures is crucial.
Information regarding fasteners and wall structures is available in

If this is achieved the testing is completed and approved.
If vertical movements of the rail is still obtained, continue tightening
the screw one Nm at a time, until the plug starts rotating in the wall.

Operation 6.2
Expander (Seismic compliance):
Tighten the bolt of the expander to 25 Nm. Check that the rail is
securely tightened against the wall. No vertical movements are
allowed. If this is achieved the testing is completed and approved.
If the expander starts rotating in the wall before 25 Nm is achieved,
it is not recommended to use expanders for mounting of the rails.
Revert to the instruction for plug & screw. See operation 1 on page
12.
4.4
Alignments
Make sure the short rails are aligned with the given tolerance
before tightening the fasteners. See Figure 4-5. Adjust if
necessary.
Insert the clevis pins in the two upper holes.
Figure 4-5 - Alignment of short rails
4.5
Tightening torque
Convert the previously established testing torque value to the
recommended mounting torque in table 2.
The lowest of the stated values in the mounting torque column is
the recommended mounting torque value. If vertical movements
can still be applied to the rail, tighten the fasteners one Nm at a
time, until the rails are securely fixed. The tightening torque must
not exceed the higher of the stated mounting torque values for
each level.

3.
Make sure the flanges of the large washer fit into the dedicated
cutouts of the base unit when turned correctly.
4.
Pressing the centre screw of each assembly bolt can perform
vertical adjustments of the base unit. (This requires
simultaneous pressing of two or four centre screws)
5.
Tighten the centre screw of each assembly bolt. This will
prevent the base unit to slide downwards.
6.
Avoid using the Clevis pins as additional supports when
mounting a fully equipped cabinet. This may cause damage to
the assembly bolts.
7.
Align the base unit with the top of the rails.
8.
Tighten the four bolts with a torque of 40 Nm. See Figure 5-6
Figure 5-6 - Locking the base unit
9.
Mount the end plugs to all rails for protection

Mounting the covers
1. Mount the bottom cover with four screws.
2. Mount the top cover with four screws.
3. Mount the side covers individually by first hooking the back end
into the slot of the base unit, and slide it forwards. Push in the
front end against base unit and lock in position by tightening the
two screws. Recommended tightening torque 2 Nm.
4. Mount the front cover by positioning the guide pins in the base
unit slots. Lock the cover by pressing the two handles
downwards until an audible click is heard.

Ground connection of subrack
When the subrack is mounted, make sure that enough torque is
used to get good ground connection to the cabinet (10 Nm). Use
tool Torx T30.

Subrack ID
The subrack identity, SUBID, is the subrack number in the
configuration file of the system node. There is a DIP-switch on the
back-plane where the number is set. Normal binary coding of the
number is used and the 4 least significant bits are decoded by the
back-plane. The Dip-switch must be set before the boards are
inserted in the subrack.

The SIS subrack has 18 slots, numbered 1-16, 29,30. Two of
these, slots 29 and 30, are half-height slots reserved for DU-3
boards. The rightmost slot, number 16, always contains a TAU-C,
while the slot number 15 always contains a TAU.
Figure 7-3 - SIS Subrack allocation
One AUS/ AUS-C pair is always located in slots 14 and 13.
The remaining 12 slots are used for AU boards.
For any partially equipped subrack, the following rules apply:
1. Place AU boards from right to left, starting at slot #12.
2. Dummy panels must cover unused slots. First, 100 mm
covers must be used as far as possible to cover four slots at
a time. Then, 25 mm covers must be used to cover any
remaining empty slots.
7.2
Fan Unit
The fan unit is always mounted above the subrack, according to
Figure 7-1. Put the Fan Unit on the guiding bars and push it in
position. Put the screws in the positions on the sides of the front.
Tighten all screws.
7.3
Cable Shelf
The cable shelf is always mounted below the subrack, according to
Figure 7-1.

AUS Synch
On AUS there is a connector to be used for clock synchronization
(Sync-Ring). The Sync-Ring is built -up in a ring structure from one
AUS to the next and back again with communication possible in
two directions as the redundancy principle.
In case of SNAR, one AUS is used and to close the ring, a loop
cable has to be implemented on AUS board itself. The cable to be
used is TSR 910 2006/300.
The cable must be connected between the AUS board outlets
called “RX” (X116-1) and “TX” (X116-5).
8.2.1.2
AUS-C - AUs cabling
The connection between AUS-C board and the AUs is performed
with unscreened balanced two pair cables with 10 poles connector,
