Lucent 0800-0411-051 TNT-SL-CT1-C channelised T1 module for TNT access concentrator.
The Lucent 0800-0411-051 is a TNT-SL-CT1-C single-slot channelised T1 module designed for the Lucent TNT (Total Networking Trunk) access concentrator platform. This card provides T1 connectivity with channelised capabilities, enabling the concentration of multiple T1 circuits for data and voice applications.
The TNT-SL-CT1-C module was deployed in carrier and enterprise environments where high-density dial-up access, ISDN PRI termination, or T1 backhaul was required. The TNT platform served as a remote access server and access concentrator, aggregating connections from multiple sources onto upstream network infrastructure.
This is a legacy product from the Lucent TNT series, which was widely deployed during the dial-up and early broadband era. The platform has been discontinued following Lucent’s merger activities, but refurbished modules remain available for maintenance of existing installations.
