China ITU SS7 Support
The China International Telecommunications Union (ITU) Signaling System 7 (SS7) Integrated Services (ISDN) User Part (ISUP) feature implements China ISUP through a SIGTRAN-based ANSI Signaling Gateway, providing the Cisco BTS 10200 Softswitch with the ability to port SIGTRAN (SCTP/M3UA) and the upper SS7 layers (ISUP, SCCP, TCAP, AIN) to an IP network. This feature additionally delivers the CiscoBTS10200 Softswitch to international markets requiring SS7 network interconnect through the China ITU ISUP protocol variant.

Note Upgrade impact: During upgrade columns TG_TYPE and SEL_POLICY will be updated with the new constraints.
Syntax Description

SS7 ANSI TG PROFILE
The SS7_TG_PROFILE table has been renamed to the SS7_ANSI_TG_PROFILE table, and three new timers, T14, T18, and T20, have been added in this table. Table 4 describes the new tokens added to this table.
Syntax Description
Table 4 SS7 ANSI TG Profile Table
SS7_ANSI_TG_PROFILE
|
Stores common information about an SS7 ANSI trunk group.
|
T14 (new)
|

|
Activated after sending CGB before receiving CGBA. SMALLINT; 4-15 seconds. Default=15 seconds.
|
T20 (new)
|
Activated after sending CGU before receiving CGUA . SMALLINT; 4-15 seconds. Default=15 seconds.
|
User Part Variant Table
The User-Part-Variant table identifies all supported SS7 user part variants and their protocol families. This table is not configurable. To support China ISUP, a new value has been added for the PROTO-FAM token.
Note Upgrade impact: During upgrade, the PROTO_FAM token will be updated with a new constraint. Multiple protocol families are now supported, a new check will be added to make sure the ID (MDO name) is compatible with the protocol family. This rule will be enforced in the form of an Oracle trigger.
Table 5 lists the modified USER-PART-VARIANT table tokens and values.
Syntax Description
Table 5 User Part Variant Table
USER-PART-VARIANT Table
|
Identifies all supported SS7 user part variants and their protocol families.

Softswitch Trunk Group Profile Table
The Softswitch Trunk Group Profile (softsw-tg) table holds all the information specific to a Softswitch trunk, such as id, protocol, indicators and echo suppression. The softsw-tg-profile record can be shared by multiple softswitch trunk groups. An ID must be created in this table before entries can be added to the Softswitch Trunk Group table.
A new token, SIPT_ISUP_VER, has been added to support China ISUP. Table 6 lists the modified Softswitch Trunk Group Profile table tokens and values.
Table 6 Softswitch TG Profile Table Modifications

Stores all information specific to a Softswitch trunk.
|
SIPT_ISUP_VER
|
Applicable when Proto-Type=sip_t. VARCHAR(32)
|
Destination Table
The Destination (destination) table defines the call type and the routing information for the dialed digits. Multiple digit strings in the Dial Plan table can use the same destination ID.
A new token, CLDPTY_CTRL_REL_ALWD, has been added to support China ISUP. Table 7 lists the modified Destination table tokens and values.
Table 7 DESTINATION Table Modifications

The Service Logic Host Route (slhr) table contains the information necessary to route a TDP request
message to a service control point (SCP).
Table 8 lists the modified SLHR table tokens and values.
Table 8 Service Logic Host Route Table Modifications

|
GTT_ADDR
|
Identifies the GTT address number of digits.INT—0-2147483647 (Default=0)
|
Subsystem Table
The Subsystem (subsystem) table holds the information for all the subsystems using SCCP. Since Cisco
BTS 10200 Softswitch supports multiple OPCs, the combined OPC-ID and SSN-ID is used as a primary
key to determine subsystem information.
Table 9 lists the modified Subsystem table tokens and values.
Table 9 Subsystem Table
APPLICATION-VERSION
|
Identifies the TCAP protocol version to be used in the query message. VARCHAR(16). Valid values are one of the following:

QWEST_AIN02 (Future)
AIN01
IN1
ETSI-INAP (Future)
ITU-INAP
CHINA
|
| |
|
Call Agent Table
A new token is added to the Call Agent (ca-config) table to allow the FSAIN to apply specific fault treatment for cases where the SCP does not provide a successful response to the BTS query.
Table 10 lists the modified Call Agent table tokens and values.
Table 10 Call Agent Table
DEFAULT-INAP-ERROR-TREATMENT
|
Indicates treatment for some INAP errors detected in FSAIN. STRING—Valid values include one of the following:
CONTINUE—Allow Call Agent default handling to route call. (Default)
ROT—reorder-tone

Trigger Identification Table
The Trigger Identification (trigger-id) table defines the trigger IDs (TIDs) supported by the
Cisco BTS 10200 Call Agent.
Table 11 lists the modified Subsystem table tokens and values.
