KX-NS5290 Panasonic KX-NS Series PBX Expansion Card

The Panasonic KX-NS5290 is a PRI 30 (Primary Rate Interface) expansion card designed to provide ISDN 30 connectivity for Panasonic KX-NS series IP communication servers. This card enables a single E1 trunk connection supporting up to 30 simultaneous voice channels, allowing businesses to maintain high-capacity digital trunk lines to the PSTN.

The KX-NS5290 is intended for installation in KX-NS500 and KX-NS700 unified communications platforms. It serves organisations requiring ISDN PRI connectivity for voice services, particularly those with existing ISDN infrastructure or where SIP trunking is not yet available or preferred.

As ISDN services are being phased out across the UK and Europe, this card is primarily suited for maintaining existing deployments or for transitional use during migration to IP-based trunk services. It remains a practical option for sites where ISDN connectivity is still operational.
