OPC (four bytes)

The address assigned to the Excel platform by the network. Every point code in the API messages will always be 4 bytes long, with the first byte (MSB) as zero. See the SS7 section of the API Developer's Guide: CCS for an explanation of how to convert the 4 bytes into ITU and ANSI point codes.

0x00000000–0x00FFFFFF:
The OPC must be in this range for signaling stacks using 24-bit point codes, for example ANSI.

0x00000000–0x00003FFF:
The OPC must be in this range for signaling stacks using 14-bit point codes, for example ITU.

If using the BT IUP protocol, the maximum range for OPC is 14 bits.

0xFFFFFFFF:
This value indicates deconfiguration of the specified signaling stack. All link sets, links, destinations, and routes previously configured to this signaling stack must be deconfigured before you deconfigure the signaling stack.

Number of Modules (n)

Module 1: Type

0x01 MTP (Message Transfer Part)
Required for any SS7 configuration or for BT IUP

0x02 ISUP (ISDN User Part)
Required if you are using the ISUP Call Control User Part

0x03 L3P (Layer 3 Plus)
Required for any SS7 configuration

0x04 TUP (Telephone User Part)
Required if you are using the TUP Call Control User Part

0x05 L3P TUP/BT IUP (Layer 3 Plus for Telephone User Part/BT IUP)
Required if you are using the TUP or BT IUP Call Control User Part

0x06 SCCP

0x07 TCAP

When using BT IUP, you must configure MTP. For example, if you are configuring the ISUP Call Control User Part, then you would send this message with three sets of module
Type and Variant fields: MTP, L3P, and ISUP.

When using the BT IUP variant, the Module Variant is 0x02. You must also configure module types 0x01and 0x03. For example, in an E1 configuration, you would specify Module Type 0x01 with a variant of 0x01, Module 3 with a variant of 0x01, Module 4 with a variant of 0x02, and Module 5 with a variant of 0x02.
