China National Variant Configuration

Overview

This section describes a configuration sequence to enable MTP/ SCCP/TCAP support for the China variant. Note that the MTP PPL Config Byte values are listed in the SS7 PPL Information, Chapter 6.

Important! National variants may require additional User Part and protocol modifications.

Configuration sequence

The following software configuration sequence (which does not have to be followed in the order presented) should be used to support the SS7 stack for SCCP/TCAP:

• Modify PPL Config Bytes with the PPL Configure message:

MTP3 HMDT component (0x002B)

• Set Config Byte 1 (Variant) to 0x03 (China)

MTP3 HMRT component (0x002C)

• Set Config Byte 1 (Variant) to 0x03 (China)

SCCP SCLC component (0x0065)

• Set Config Byte 1 (Variant) to 0x02 (China)

Example

In a configuration with two SS7 stacks (Stack 00 and Stack 01), the following PPL Configure messages would be sent to the CSP. The shaded columns (asterisk* for html documents) indicate modifications. Abbreviations used in the table are:

• Seq. No. - Sequence Number

• LNI - Logical Node ID

• PPL Comp. ID - PPL Component ID

Length (MSB, LSB) | Message Type (MSB, LSB) | Reserve Byte | Seq. No. | LNI | AIB | Stack* | PPL Comp. ID* | PPL Entity | # Data Location | Byte | Data*
