6.2.2 Connecting PRI

TEPRI/TEPRIa boards can be connected to a PRI C.O. circuit through a RJ-45 port. As show
below, connect a T1/PRI circuit to the PRI port of the OfficeServ 7200-S system. Though the
TEPRI/TEPRIa board supports E1 & T1, it is not used in this product.
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/TEPRIa 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.
