ADTRAN 1200054L1 NT56/64 V35 OPTION MODULE

When your application requires an EIA-530 or EIA-449 interface, the Nx56/64 EIA-530 (expansion) Module should be selected. Available as a plug-in module only, the EIA-530 (expansion) Module provides a single, female DB-25 interface which can be adapted to EIA-449 (user supplied cable). For future expansion, the Nx56/64 EIA-530 expansion Module accepts most plug-on modules. This module is suitable for router, audio systems, video systems and switches that require a synchronous EIA-530 or EIA-449 DTE interface.
