5.2
There is no special programming required for OPX use; however, it is suggested that
the OPX ports are set for CO ring in MMC 208. The telephone company service facility
interface code for OPX circuits is OL13C.
5.7 T1 CIRCUIT
Using a standard, straight through eight conductor data cable or straight through eight
conductor line cord to connect the customer provided Channel Service Unit (CSU) to
the TEPRI card as shown in
NOTES:
1. It may be necessary to cut off the CSU end of the cable and attach a different
connector to match that of the CSU. If possible, this connection should be soldered
because good connections are critical.
2. It is recommended that the CSU be connected to the network interface with a cable
supplied by the CSU manufacturer. If this is not possible or practical, a custom
cable has to be made up. This cable should be made from 22 gauge two pair cable
with each pair individually shielded. It is recommended that the connections on this
cable be soldered wherever possible to ensure good connections. The shielding of
the cable should be connected to ground at the CSU end only to prevent a ground
loop.
