Alcatel 90-7272-01-B Adapter Card For 7670 T1 E1

Alcatel 90-7272-01-B Adapter Card for 7670 T1/E1 is a T1/E1 interface adapter designed for the Alcatel-Lucent 7670 Service Router family. This adapter card supplies T1 and E1 connectivity to the 7670 platform, allowing termination and routing of digital circuits within the router. The part is identified by 90-7272-01-B and is documented in reseller and technical catalogs as the 7670 T1/E1 adapter option. In typical deployments, network operators install the card to attach T1 or E1 service lines to the 7670, enabling voice and data services to be carried over IP networks via the router's service edge capabilities. The 7670 line is part of Alcatel-Lucent's enterprise/carrier routing portfolio, later continued by Nokia, and cards in this family are designed to plug into compatible chassis and backplanes to extend interface options. As with other platform-specific adapter cards, this module should be matched to the router's hardware revision and software release to ensure compatibility and proper operation.
