State Syncing on PPL Event Request for ANM

Terminology

The following terminology appears in this section.

• L3P CIC - Layer 3 Protocol Circuit Identification Code

• L3P BT IUP - Layer 3 Protocol British Telecom Interconnet User Part

• L4CH - Layer 4 Channel

Feature Overview

Prior to this feature, when the PPL Event Request for ANM is sent either to L3P CIC component of ANSI/ITU or to L3P BT IUP component the L4CH SM is not in the answered state. To put the L4CH SM in answered state, you needed to use a custom PPL.

This feature puts the L4CH SM in an answered state when the PPL Event Request for ANM is sent to either of the following:

• L3P CIC component of ANSI or ITU

• L3P BT IUP component for BT IUP

Enabling this Feature

This feature is disabled by default. Follow the steps below to enable it.

ANSI and ITU Protocols

In the L3P CIC component, set configuration byte 0xA7 to 0x01.

Use the PPL Configure (0x00D7) message to enable this feature as follows:

00 12 00 d7 00 00 FF 00 01 0d 03 00 01 01 00 0f 01 01 a7 01

BT IUP Protocol

In the L3P BT IUP component, set configuration byte 0x3F to 0x01.

Use the PPL Configure (0x00D7) message to enable this feature as follows:

00 12 00 d7 00 00 FF 00 01 0d 03 00 01 01 00 11 01 01 3f 01

Querying

Use the PPL Query message (0x00DE) to query the PPL configuration bytes above.

ANSI / ITU
