BE110258 NEC NEC SL1100 PBX Expansion Card

The NEC BE110258, also known as the IP4WW-EXIFB-C1, is an expansion interface board designed for the NEC SL1100 business telephone system. This card provides the necessary connectivity to link additional expansion chassis to the main system unit, enabling businesses to scale their telephony infrastructure beyond the base system capacity.

The EXIFB-C1 expansion interface board is essential for larger SL1100 deployments where the base chassis cannot accommodate all required station and trunk cards. By connecting expansion units, organisations can add further digital stations, analogue extensions, and trunk interfaces to meet growing communication demands.

The NEC SL1100 platform has been a popular choice for small to medium-sized businesses requiring a reliable on-premise PBX solution. While this system is now considered a legacy platform with NEC having transitioned to newer unified communications solutions, existing installations continue to operate in many organisations requiring maintenance and expansion components.
