The Norstar 6 Port Expansion Card is used on the Norstar Modular ICS KSU unit and allows for up to 6 expansion modules (fiber trunk module or fiber station module) to be added to the MICS. By adding 2 of these cards to the KSU, the control unit will be capable of 12 expansion ports. (Must have XC Software to add 2 expansion cards).

This card can also be used for NAM voice mail modules which can be added to the system.
