You can install this card in slots 1 through 4 in the MG 1000S. The card is not supported in the MG 1000S Expansion.

IMPORTANT!

Each MG 1000S that has a digital trunk must have a clock controller

clocked to an external reference clock.

Note: Clocking slips can occur between MG 1000S systems that are clocked from different Central Offices (COs), if the COs are not synchronized. The slips can degrade voice quality.
