(ITG) Line Card
Overview
ITG Line card is supported on Option 11C, 11C Mini, 61C, 81C on x11Release 25 or above which enables
IP terminals to be deployed that deliver the feature rich suite of Meridian Digital Services over a single

The ITG card has 24 DSP ports that provide gateway functionality to facilitate the bridging (conversion)
of voice streams between the packet switched (IP) data network and the circuit switched PBX network.

In this capacity the ITG Line card is responsible for registering the IP sets and keeping track of the maximum
number of sets that can be registered per card.
