TECHNICAL MANUAL

3.3.3 TEPRI/TEPRIa

The T1E1PRI(TEPRI/TEPRIa) board is a digital trunk interface that supports ISDN PRI service. It
also supports Q-Sig/PRI signalling required for networking multiple systems.
The TEPRI/TEPRIa board installs in slots 3, 4 or 5 of cabinet. The first four LEDs on the front of
the card provide the status of the service (Sync, AIS, Loss and Layer 2 Active states). The
second four LED on the front of the card display the type of service. The first TEPRI/TEPRIa
card installed in the OfficeServ 7200-S is the primary source of external clocking. The second
TEPRI/TEPRIa installed is the secondary source of external clocking. Default clock selection is
first cabinet, left to right then second cabinet. The clock priority can be changed by using
MMC 826. The primary and secondary clock sources should be mounted in the main cabinet
to ensure stable reception of clocking from the primary and secondary sources. There are two
RJ45 modular jacks on the face of the card. The settings for PRI service are selected by a bank
of dip switches as defined below. The PRI supports NI1, NI2, AT&T No. 5 ESS, and DMS 100
offices. A maximum of 2 TEPRI/TEPRIa cards can be provided per system. NOTE: Do not insert
this card with system power ON.
