BE106346 NEC NEC SV8100 PBX Expansion Card

The NEC BE106346 CD-4COTA is a 4-port analogue trunk card designed for the NEC SV8100 business telephone system. This expansion card provides connectivity for up to four analogue CO (Central Office) trunk lines, enabling the PBX to interface with traditional PSTN telephone services.

The CD-4COTA card installs into the SV8100 chassis and allows businesses to maintain analogue trunk connectivity alongside digital and IP-based services. This is particularly useful for organisations requiring PSTN fallback capability or those operating in areas where analogue lines remain the primary telecommunications infrastructure.

The NEC SV8100 platform has been superseded by newer NEC communication systems, making this card a legacy component. However, it remains essential for maintaining and expanding existing SV8100 installations where analogue trunk capacity is required.
