Figure 1. Cisco PGW 2200 Softswitch Nodo de Arquitectura
Cisco SLT utiliza el protocol Reliable User Datagram Protocol (RUDP) para poder integrar la capas
superiores de SS7 atravez de la IP signaling control network con el Cisco MGC. Cisco RUDP es una simple
conexcion –orientada a paquetes basado en la capa de transporte RFC 908 (Reliable Data Protocol) and
RFC 1151 (Version 2 of the Reliable Data Protocol).
Las capas superiores SS7 entregan :
• MTP3
• ISUP
• Signal Connection Control Part (SCCP)
• Transactions Capabilities Applications Part (TCAP)
• Advanced Intelligent Network (AIN)
• Intelligent Network Application (INAP)
Cisco SLTs usa Cisco IOS® Software SS7 SLT entregando una integración con el Cisco PGW 2200 Softswitch node.
Cisco Session Manager software administra las sessiones de comunicacion con el Cisco MGC.
Figure 2. SS7 Signaling Backhaul Architecture
The integrated SLT option is appropriate for any voice-over-IP (VoIP) network deployment, pero está
bien adaptado para redes más pequeñas y altamente distribuidos que requieren muchos pequeños
puntos de presencia (POPs) or local interconnect points. Combined with a low-end Sun platform as the
Cisco MGC and a Cisco AS5350XM acting as the universal gateway and SLT, it is possible to build a
"micro-POP" that can be deployed in as little as 3 rack units (3RUs). Figure 4 illustrates this concept

Configuration Examples
HABILITAR E1 EN EL NAS - SS7
The first set of steps in this section create the interface serial object that will later be configured
as an SS7 digital link.
Command
Purpose
Step 1 Router# configure terminal
Enters global configuration mode.
Step 2 Router(config)# controller {e1|t1} Selecciona la ranura y el tronco cuya timeslot you want to
slot-number /PRI-trunk
use to create an SS7 link.
Step 3 Router(configcontroller)# channel-group gid
timeslots ts
Associates a channel group with the desired timeslot for the
SS7 link.
Note The channel-group (gid) must be one number less than
the timeslot (ts). This is true only if you are using this for
SS7 links. Only one timeslot is allowed per channel group
when used for SS7.
Step 4 Router(config-controller)# exit
Router# configure terminal
Router(config)# controller
Router(config-controller)#
Router(config-controller)#
Router(config-controller)#
Exits configuration controller mode.
t1 7/3
channel-group 11 timeslots 12
channel-group 23 timeslots 24
exit
The next set of steps convert the interface serial object created above into an SS7 digital link.
Command
Purpose
Step 1 Router(config)# interface serial
slot-number:gid
Specifies a serial interface created on a channelized E1
or channelized T1 controller.
Step 2 Router(config)# encapsulation ss7
Changes encapsulation to SS7.
Step 3 Router(config-if)# channel-id
channel-id
Selects a unique session channel ID. This session
channel ID is needed when associating the link with
an RUDP session to the MGC.
Note The channel-id command is visible only if the
object's encapsulation type is changed to SS7.
Step 4 Router(config-if)# no shutdown
Enables the SS7 link.
Step 5 Router(config-if)# exit
Exits configuration interface mode.
Router(config)# interface serial 7/3:11
Router(config-if)# encapsulation ss7
Router(config-if)# channel-id 3 >>> se require para asociar con el RUDP
session al MGC.
Router(config-if)# no shutdown
Router(config)# interface serial 7/3:23
Router(config-if)# encapsulation ss7
Router(config-if)# channel-id 2 >>> se require para asociar con el RUDP
session al MGC.
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# end
Verifying SS7 Digital Links
To display information for a given session channel ID, enter the show ss7 mtp1 channel-id
command in privileged EXEC mode. If no channel ID number is selected, information for all
assigned channel IDs is displayed. This command is useful for determining which channel IDs
have already been allocated.
Router# show ss7 mtp1 channel-id >>> se muestra las sesiones channel id.

To display information for each provisioned SS7 link, including the name of the serial interface
for the link, the assigned MGC port, whether the link is serial (12-in-1 port) or digital (E1/T1
trunk DS0), the assigned channel ID, and whether the link is stopped or started, enter the show
ss7 mtp1 links command in privileged EXEC mode:

Configuring the Physical Interfaces
Cisco SLT T1/E1 Multiflex Trunk Interfaces Overview
The T1/E1 multiflex trunk interface cards are dual-mode T1 or E1 interfaces in a VWIC
(Voice/WAN Interface card) form for voice, data, and integrated voice and data applications.
They support the SS7 Cisco SLT function, as do serial WICs.
The T1/E1 VWIC supports the following T1/E1 functionality:
•
Single or dual port, structured or unstructured T1/E1 functionality
• Drop and Insert (also called TDM Cross-Connect) between the T1/E1 ports on dual-port
cards, used to hairpin bearer channels to a media gateway device and allowing the interchange of
time-division multiplexing (TDM) slots between the ports on a two-port card
•
Physical layer alarm forwarding feature between the two E1/T1 ports on dual-port cards
For additional information about the T1/E1 multiflex trunk interface cards, refer to the Cisco
WAN Interface Cards Hardware Installation Guide.
Configuring T1/E1 Multiflex Trunk Interfaces
Router# configure terminal
Router(config)# controller E1 3/0
Router(config)# framing CRC4
Router(config-controller)# linecode hdb3
Router(config-controller)# line-termination 120-ohm
Specifies the channel group and time slots to be mapped.
• Only channel group 0 can be configured. Generally, only one time slot is configured when you are
using the Cisco SLT feature. For example, time slot 24 is used for a T1 interface, and time slot 16 is used
for an E1 interface.
• The channel-group command creates a virtual serial interface. It is numbered slot/port:subinterface,
as follows:
– slot is the slot location of the WIC/VWIC where the channel group was created (always 0).
– port is the WIC/VWIC port address (0 to 3).
– subinterface is the channel group number (always 0).
• Return to Step 2 if your router has other T1/E1 interfaces that you need to configure.

The "drop-and-insert" application feature, also known as time-division multiplexing (TDM) crossconnect, allows customers to deploy F links with both signaling and bearer traffic on the same facility.
This feature grooms the SS7 signaling channels from the facility and backhauls the signaling to a Cisco
MGC for processing. Bearer channels are "hairpinned" on the Cisco SLT Interface Card and sent to a
voice gateway by connecting a cable between the egress port on the Cisco SLT VWIC and an available T1
or E1 port on a gateway.
The integrated SLT offers an internal drop-and-insert feature that requires no external cabling. All bearer
channels are internally hairpinned on the gateway and sent to the VoIP network. Figure 5 depicts both
the Cisco SLT and integrated SLT drop-and-insert architectures.
SUPPORTED SS7 NETWORK INTERCONNECT METHODS USING THE CISCO SLT
When the Cisco PGW 2200 Softswitch is used in Cisco VoIP networks, the solution supports common signaling
interconnect methods as well as features that exploit the power and savings of transporting SS7 signaling over IPbased networks.
A LINKS
Access or A links are used between the service switching point (SSP), served by the Cisco PGW 2200 Softswitch,
and the signaling transfer point (STP) to connect the VoIP network to the PSTN. These links are dedicated to
signaling, meaning that no bearer traffic is provisioned on the facility, even if available time slots are not being used
for signaling. For reliability, there are generally, at a minimum, two A links provisioned between the SLTs and the
home STPs. Although most commonly seen in North America, A links are used in other geographic areas such as
Asia and South America, depending on availability of facilities.
F LINKS
Fully associated or F links are generally deployed when a large volume of traffic exists between two SSPs (between
the Cisco PGW 2200 Softswitch and a PSTN switch, for example) or when it is not feasible to connect directly to an
STP. F links are not commonly used in North America, but they are widely deployed in Europe, Asia, and South
America. Although F links can be provisioned with only signaling on the facility, the most common configuration
includes the provisioning of bearer channels on time slots not used by SS7 signaling.

ADD TRUNK NAS A LA PSTN SWITCH
Se debe añadir troncales para cada conexion NAS y la PSTN Switch
Usando un text file
Using a text file to add trunks requires you to create a text file that contains the following fields:
• Trunk ID—A unique identifier, maps to NAME (trunk ID).
• Source Service Name—The signaling service you created in “Adding the SS7 Signaling Service”
section on page 3-22; used to look up SRCSVC.
• Source Span ID—Maps to SRCSPAN (converted from decimal to hexadecimal except when value
is ffff).
• Source Time Slot—Identifies the time slot on the T1 at the destination (PSTN switch). Maps to
SRCTIMESLOT (converted from decimal to hexadecimal except when value is ffff).
• Destination Service Name—The signaling service for the NAS you created in “Adding NAS
Signaling Services” section on page 3-32. Used to lookup DSTSVC.
• Destination Span ID—The appropriate T1 line and T1 controller on the NAS. This value is the
nfas_int value that is set in IOS on the NAS. Maps to DSTSPAN (converted from decimal to hex
except when value is ffff).
• Destination Time Slot—Identifies the time slot on the T1 that terminates at the NAS. Maps to
DSTTIMESLOT (converted from decimal to hexadecimal except when value is ffff)
The following example shows the trunk text file for the sample configuration in this chapter. The fields
in the text file correspond to the fields described above.

enable
show ss7 sm session
show ss7 sm set
show ss7 sm stats
DETAILED STEPS
Command or Action
Step 1 enable
Example:
Purpose
Enables privileged EXEC mode.
•
Enter your password if prompted.
Router> enable
Step 2 show ss7 sm session
Displays information about an SS7 session
manager session.
Example:
Router# show ss7 sm
session
Step 3 show ss7 sm set
• (Optional) You can specify a session
number of 0 or 1.
Displays information about the failover
timer setting.
Example:
Router# show ss7 sm
set
Step 4 show ss7 sm stats
Displays information about session manager
statistics.

stats
• (Optional) You can specify a session
number of 1 or 2.
Configuring the MTP2 Variant
SS7 MTP2 supports four variants: Telcordia (formerly Bellcore), ITU, NTT (Japan), and TTC
(Japan Telecom). The parameters under one variant have different meanings, purposes, and
ranges in another.
See the following command references for the appropriate MTP 2 variant commands and the
parameters:
•
•
ss7 mtp2-variant bellcore
ss7 mtp2-variant itu
•
•
ss7 mtp2-variant ntt
ss7 mtp2-variant ttc
Note Parameters that are not configured will remain at the default values.
The channel to be configured must be out of service at the MGC before the variant or the variant
configuration can be changed.
Note Once the variant configuration changes have been made, the router must be reloaded to
apply the changes.
SUMMARY STEPS
1. enable
2. configure terminal
3. memory-size iomem i/o-memory-percentage
4. ss7 mtp2-variant bellcore 2
5. T3 30000
6. unacked-MSUs 16
7. T7 50000

10. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1
Purpose
enable
Enables privileged EXEC mode.
Example:
•
Router> enable
Enter your password if prompted.
Step 2
configure terminal
Enters global configuration mode.
Example:
Router# configure
terminal
Step 3
mem iomem i/o-memorypercentage
Sets the amount of DRAM to be used
for I/O memory to 40 percent.
Example:
• The values permitted are 10, 15, 20,
25, 30, 40, and 50 percent. A minimum
of 4 MB of memory is required for I/O
memory.
Router(config)# mem
iomem 40
• If you do not set the I/O memory to
at least 40 percent, there will not be
enough memory for the SS7 MTP2
signaling.
Step 4
ss7 mtp2-variant
Bellcore 2
Configures the MTP2 variant Telcordia
(formerly Bellcore) for channel 2.
Example:
• Enters Bellcore variant
configuration mode.
Router(config)# ss7 mtp2variant Bellcore 2
Step 5
T3 30000
Sets the aligned timer to 30,000
milliseconds.
Example:
Router(config-Bellcore)#
T3 30000
Step 6
unacked-MSUs 16
• Valid values range from 1000 to
65535. Default is 11500.
Sets the maximum number of MSUs
waiting for acknowledgment to 16.
Example:
Router(config-Bellcore)#
unacked-MSUs 16
Step 7
T7 50000
• Valid values range from 16 to 127.
Default is 127.
Sets the excessive delay timer to 50,000
milliseconds.
Example:
Router(config-Bellcore)#
T7 50000
• Valid values range from 500 to
65535. Default is 1000.
Step 8
Exits Bellcore variant configuration
mode.

The MGC provides call control. Once the Cisco SLT is configured, you must configure the point
codes, linksets, SS7 signaling links, and the associated MTP 2 parameters on the MGC.
Each SS7 link defined on the MGC is considered a logical channel, and each logical channel
corresponds to a physical interface on the Cisco 2611. You can define two SS7 links (logical
channels) from the MGC to a Cisco 2600 series router. The logical channels defined on the TCS
map to the physical serial interfaces on the router from right to left, as follows:
•
Numbering for an interface in the first slot always starts with channel 0.
•
Numbering for an interface in the second slot always starts with channel 2.
•
If a slot is empty, these rules still apply.
Table 1shows some examples of how different signaling termination channels might map to
interface positions.
For more information about configuring the MGC software, refer to the Cisco Media Gateway
Controllers documentation on Cisco.com.
