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.

SOFTSW-TG-PROFILE

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

DESTINATION

Defines the call type and the routing information for the dialed digits.

CLDPTY_CTRL_REL_ALWD

Called party controlled release support. CHAR(1): Y/N (Default = N).


Service Logic Host Route Table

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

SERVICE-KEY

Determines whether number portability or freephone (8XX) service logic is being invoked. BTS is limited to one service key per 8XX or LNP service per OPC. SMALLINT—0-255

TT

Identifies the translation type. SMALLINT—0-24 (Default=0)

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:

AIN02 (Future)

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.

Table 11 Trigger Identification Table

SPECIFIC_DIGIT_STRING

Used for 800/freephone calls triggers.

LNP_TRIGGER

Local number portability trigger.
