The Norstar 6 port fiber combo expansion card(NTBB25GA) is for the MICS Modular Integrated Communication System. It allows the expansion of lines and/or stations via the 12X0 fiber trunk module, 0x8 or the 0x16 fiber station modules for Modular ICS systems as well as providing the clocking source for the T-1/Digital Circuit provided by the telephone company.
The Modular ICS control unit will support up to 2 T-1 for Digital Trunk connection, and this card has the T-1 clock card built in. By adding this card you are gaining not only six ports of expansion but also the hardware necessary for adding a digital T-1/ PRI. Without the clocking source installed in the Norstar system the T-1 Digital circuit would not work. Depending on the size of the configuration, this card goes in either slot 1 or 2 on the MICS KSU. When purchasing this card you are getting two cards for the price of one. Ideal for those companies requiring maximum expansion along with a digital circuit.
