3.5 OTHER INTERFACE CARDS

3.5.1 TEPRI and TEPRIa
The TEPRI(TEPRI/TEPRIa) card is a digital trunk interface that supports either T1 or ISDN PRI
service. It also supports Q-Sig/PRI signalling required for networking multiple systems.
NOTE: The OfficeServ 7100 only supports PRI and does not support T1
service even though the TEPRI and TEPRIa cards support both.
The TEPRI/TEPRIa card can be installed in slots 1 and/or 2. 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 LEDs on the front of the card display the type of service. The first TEPRI/TEPRIa
card installed in the OfficeServ 7100 is the primary source of external clocking. The second
TEPRI/TEPRIa installed is the secondary source of external clocking. Default clock selection is
left to right in the cabinet. The clock priority can be changed by using MMC 826. Regardless
of position, a CO PRI circuit should always be given clocking priority over T1 circuits. There are
two RJ45 modular jacks on the face of the card. The settings for T1 or 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.
