Panasonic 1200N User Manual

The ATM Switch uses UTP (Unshielded Twisted Pair) category 5 cables for OC-
3c/STM1-UTP-5. 

The UTP-5 cables are connected with RJ-45 modular connectors. 

The pin assignment of the RJ-45 modular jacks conform to that of ATM Network
Equipment of ATM Forum UNI standard Ver 3.1.

Maximum transmission distance is 328 ft. (100 m).

Twisted pair cables are connected with RJ-45 connectors. Twisted pair cables are
used for Primary, DS1, and E1. When equipment is installed in a Central Office
environment, shielded cables and connectors must be used.

Coaxial cables are connected with BNC connectors. Coaxial cables are used for
6.3M-J2, 45M-DS3 and 34M-E3. 6.3M uses a 3C-2V coaxial cable to transmit cells
up to 200 m.

The type and quantity of cables differ from one line card to another. Prepare the
necessary cables in necessary quantities and connect the line cards. 

Be careful of the cable type (single-mode or multi-mode) and the transmission-
reception direction when connecting optical fiber cable and the transmission-
reception direction when connecting coaxial cable.

Whatever the cable type, be sure to connect them securely.

Always hold the connector when connecting or disconnecting cable. Holding the 
cable or pulling on the cable may cause disconnection.
