BE110290 NEC NEC SL1000/SL1100 PBX Expansion Card

The NEC BE110290, also known as the IP4WW-VOIPDB-C, is a VoIP daughter board designed for use with NEC’s SL1000 and SL1100 series business telephone systems. This expansion card enables Voice over IP functionality, allowing the PBX to handle IP-based telephony alongside traditional circuit-switched connections.

The IP4WW-VOIPDB-C integrates with the SL1000/SL1100 CPU or main processing unit, adding VoIP channel capacity to the system. This allows businesses to leverage IP trunking for cost-effective external calls or to support IP endpoints within their telephony infrastructure.

The NEC SL1000 and SL1100 platforms are legacy unified communications systems that were widely deployed in small to medium-sized business environments. While these systems have been superseded by newer NEC platforms, they remain in active use at many sites requiring ongoing maintenance and expansion support.
