The Emerald ICE Key Service Unit (KSU) is designed as a modularized, flat‐pack.
Two KSU’s (KSU3 and KSU4) may be equipped to attain the total system capacity
of 24 CO lines, 58 Extensions (46 digital and 18 analog) and 8 Voice Processing
Channels. Each KSU is designed to be mounted on the wall and is shipped with a
wall mounting template. The compact KSU weighs less than 20 pounds and is UL
Listed.
If using 2 KSU’s, the first KSU, or KSU3 is factory equipped with one 610+2 Board,
one CCB (Common Control Board). The second KSU or KSU4 is factory equipped
with one Base Board module. Each KSU is a self‐contained cabinet containing an
internal power supply for either 117vac or 230vac operation. At the time of
shipping it is set for 117vac operation. From the exterior, with covers in place,
KSU3 and KSU4 look identical, however, KSU3 contains the Common Control
Board(CCB).
