0x0033 NPDI Universal ICB

The Route Control message is sent with the following ICB to obtain a span/channel for an incoming call. This ICB is required for IP and Interworking calls.

The NPDI SIP Response Code TLV (0x2915) appears in this ICB when it is used in the Channel Released with Data message and Release Channel with Data messages. This ICB is required for the VDAC-ONE and IP Network Interface Series 2 cards.

This ICB is required to support Frequency Shift Keying for the DSP Series 2 card.

The maximum recommended NPDI size is as follows:

• 780 for the Route Control message (including the NPDI ICB size)

• 820 bytes for Outseize Control message and the other messages below (including the NPDI ICB size)

Used in:
Outseize Control message
PPL Event Indication message
PPL Event Request message
Route Control message
Connect with Data message
Request for Service with Data message
Channel Released with Data message
Release Channel with Data message

Internet Protocol. Part of the TCP/IP family of protocols used to route messages and tracks the addresses of nodes.
Interworking is a software feature within the Excel platform call control layer that enables protocol conversion by analyzing and converting Network Signaling (NS) Layer 3 information.
Network Protocol Data Intelligence. Also called “Interworking,” it is a software product that operates within Excel’s Call Control (Layer 4) and Services (Layer 5) call processing layers. NPDI is meant to enhance Excel’s call processing product offering by allowing call processing layers (specifically Layers 4 and 5) to perform advanced analysis, generation, and conversion of Network Signaling (NS) Layer 3 information.
Session-Initiation Protocol. A signaling protocol used for establishing sessions in an IP network. A session could be a simple, two-way telephone call, or it could be a collaborative multi-media conference session.
Tag-Length-Value block. A standardized block that allows data to inserted in a standard way into API messages.
Digital Signal Processor
Outgoing call setup during real-time call processing on a specific channel.
See Programmable Protocol Language.
A condition that, when met, drives a state machine from one state to another. A condition that drives a Component out of its current state by invoking an associated primitive.
ITU-T standard defines a set of call control, channel setup, and codec specifications for transmitting real-time voice and video over networks that do not offer guaranteed service or quality of service.
