Understanding the Turkish ISUP Feature

The Cisco BTS 10200 Softswitch provides support for the Turkish ISUP variant. The Turkish ISUP feature is based on the ITU-T Q.767 specification and the Turkish-ISUP implementation in the PGW 2200 softswitch. This feature delivers the Cisco BTS 10200 Softswitch to the Turkish markets requiring SS7 network interconnect through the Turkish ISUP protocol variant.

The features and services supported in Turkish ISUP are organized into the following categories:

Q.767 Message Support

Q.767 Parameter Support

Provisioning

This section explains how to provision the default values of the timers for the Turkish ISUP variant.


Note For complete CLI information, see the Cisco BTS 10200 Softswitch CLI Database.


You need to explicitly set the following timer values in the SS7 Trunk Group Profile table, to enable BTS to use the Turkish ISUP configurations:

Timer Type
Value (seconds)

t36

15000

t35

18000

t26

120000

t25

5000

t24

1000

t22

10000

t20

10000

t18

10000

t16

10000

t14

10000

t12

10000

t9

180000

t8

15000

t7

20000

t6

20000

t1

10000



Note For complete CLI information, see the Cisco BTS 10200 Softswitch CLI Database.



Note In the Cisco BTS 10200 Softswitch, the default values in the configuration tables for Trunk Group (TG) profile are not specific to any variant. It is expected that you will provision the TG profile with variant-specific timer values. For example, if a Turkish ISUP customer requires that BTS follow the Turkish ISUP-specific timer values at the ISUP level, the values should be configured in the SS7 Q767 Trunk-Group profile. This profile should then be used when the Turkish ISUP Trunk-Group is provisioned.


Operating

A new value has been added to the installed default variant base to support Turkish ISUP. It introduces the value Q767_TURKISH for the ID token in the User Part Variant Base and User Part Variant tables.

To use the Turkish-ISUP feature, you need to perform the following configurations in the EMS CLI:

Add Q767_TURKISH as the user-part variant id in the User Part Variant table.

Specify Q767_TURKISH as user-part-variant-id while you are configuring the call control route of a Q767 Turkish trunk in the Call Control Route table.
