The test effort verified a basic level of interoperability between the Adtran - Total Access 900/900e Series Multi-Service Access Gateway Release 14.2, and Nortel’s Multimedia Communication Server 5200 (MCS 5200) Release MCS9.1. This successful testing establishes the Adtran - Total Access Series as a Nortel registered product for the releases 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 Adtran Total Access Series with the MCS based on their network deployment requirements.
