Note: The CIM ports are the same whether the card has a control end con-

nection or a peripheral end connection. Connections from the control

cabinet to the peripheral cabinet require Category 5 UTP (unshielded

twisted pair) cable with TX and RX pairs reversed.

Note: The RS-232 ports (Maintenance, Printer, J10, J11) are all configured

as DTE type. All backplane connections use DB-9 connectors. The

pins with * and ** are connected together on PRI maintenance ports

(slots 10 and 11).
