The Nortel NTR651BS is an External Bridge board (EXT BRG BD) for the DMS-100 SAM21 subscriber-access shelf. It provides the bridging connection that ties the SAM21 power and control buses together, extending power and signalling distribution across the shelf so its peripheral modules operate as a single managed unit. The NTR651BS is a shelf-infrastructure component of the DMS-100 central-office switch, not a subscriber or trunk circuit pack, and it works alongside the SAM21 alarm, breaker and power/fan modules. The DMS-100 is a Class 5 digital switch that remains in carrier service worldwide, so spare SAM21 modules such as the NTR651BS continue to be required for maintenance and repair. We supply the NTR651BS refurbished and tested. Submit a price enquiry for availability and lead time.
