The test effort verified a basic level of interoperability between the Mediatrix 4100 Series product release MGCP v5.0 and Nortel’s Communication Server 2000 (CS 2000) Release SN09U. This successful testing establishes the Mediatrix 4100 Series Gateways as a Nortel Compatible product for the release(s) tested. Testing included basic communication and basic call functionality between the devices. It is the service provider’s responsibility to perform appropriate system and network integration of the Mediatrix 4100 Series product with the CS 2000 based on their network deployment requirements.
