Note: The 3300 Universal ASU connects to the 3300 Controller over a
Category 5 Universal Twisted Pair (UTP) cross-over cable through a CIM
interface. The Category 5 cable is of the same type used for Ethernet
connections and within the cable twisted pairs are arranged as: 1,2: 3,6;
4,5; 7,8. Each tied pair is connected to a 75 ohm resistor. The 3300
Universal ASU can be located up to 30 meters (98.4 feet) away from the
3300 Controller. The interface employs a single standard 8-pin modular
jack consisting of 2 balanced signal pairs and is located on the front of
the unit.
Note: Connection of the Tip and Ring (A and B) leads of the ONS lines
and LS trunk circuits are through a 25 pair female D-type connector.
