TECHNICAL MANUAL
TEPRI2 CARD
The TEPRI2 card is a DUAL circuit digital trunk interface that supports either T1 or ISDN PRI
service. It also supports Q-Sig/PRI signaling required for networking multiple systems. This
card is functionally identical to the TEPRIa card, however, it offers two independent circuit
interfaces labeled P1 and P2 on the front panel. The TEPRIa offers only a single circuit.
SPECIFICATIONS
 In order to use both circuits of the TEPRI2, it must be installed in the main cabinet. If the
TEPRI2 is installed in an OS7400 expansion cabinet, only the first circuit can be used. The
second circuit will be disabled.
 The TEPRI2 CANNOT be used in an OS7200 expansion cabinet.
 BOTH circuits P1 and P2 must be used for the same function: either both are TELCO
interfaces OR both are used for QSIG PRI networking. One cannot be used for Telco, while
the second interface is used for Q-Sig/PRI networking.
 Add as many TEPRI2 cards as needed.
