ISUP CPC (0x0012)

Purpose

This section includes ITU and ANSI PPL Config Bytes, all PPL Events, and Timer information for the PPL Component ISUP CPC.

Use of Blocks

Blocks are used to organize the PPL configuration bytes. Each block does not exceed 200 configuration bytes. The ISUP CPC component has three blocks of configuration bytes. These blocks must be reference when using the bytes.

Description

Value

0x01

Dual-seizure Control Flag

 

 

0x00 Drop Outgoing Call

0x01 Drop Incoming Call

0x02 Drop Incoming Call if OPC is less than DPC and CIC is odd, or OPC is greater than DPC and CIC is even (see Q.767 D2.10.1.4) (default)

0x02

0x00

0x09

Send RFS to host after incoming continuity result is received.
When setting this byte to 0x01, the host should not try to send any call processing API on the circuit where incoming Continuity Check is being performed, until continuity check results are received in the form of PPL Event Indication.

0x00 = Send RFS after Continuity has been performed


0x01 = Send RFS before Continuity has been performed
