Specifications

net, this card can only be installed in slot 3. This card is also used for networking to other systems (QSig/PRI net-
working)*. Add as many as required.
TEPRI2 CARD
This is a dual circuit digital trunk interface card. It offers the exact functionality of the original TEPRI card. The dif-
ference is that it combines two TEPRI cards into one board.
Each circuit provides 24 channels for T1/PRI CO trunking OR for Qsig over PRI networking so you can network to
other OfficeServ systems. This means in one slot, you get 48 channels for T1, PRI or Qsig functions. This card can
be installed in any universal slot, however, you get dual circuits in the main cabinet only and a single circuit per
card in an OS7400 expansion cabinet. You cannot install this card in an OS7200 expansion cabinet. There are no
limits to how many you can install in a system.
NOTE: BOTH CIRCUITS MUST BE USED FOR CO TRUNKING OR BOTH FOR QSIG PRI NETWORKING. YOU CAN-
NOT SPLIT THE FUNCTIONALITY BETWEEN THE 2 CIRCUITS.
