Ericsson KDU13005/4 FECU upgrade card supporting up to 48 portable devices.
The Ericsson KDU13005/4 is a Fixed End Capacity Upgrade (FECU) card designed to expand the portable device capacity of Ericsson wireless telephony systems. This upgrade module enables support for up to 48 portable handsets, providing essential scalability for growing enterprise communications infrastructure.
The FECU card is typically deployed within Ericsson’s MD110 or BusinessPhone PBX systems to increase the number of concurrent DECT or wireless handsets that can be registered and operate simultaneously. This makes it particularly valuable for organisations requiring expanded wireless coverage and user capacity.
As a legacy Ericsson telecommunications component, this FECU upgrade card serves ongoing maintenance and expansion requirements for existing MD110 and BusinessPhone installations. While these platforms have been superseded by newer solutions, many enterprises continue to operate and maintain these proven systems.
