cabinet(type A or B). Firmly push in the middle of the card to ensure that it is fully inserted
into the back plane connector. PRI card needs PLL board installing first. Before installing
PRI card, PLL board must be installed.
The TEPRI card is installed in the DCS slot on expansion cabinet. The iDCS(OfficeServ)
100 supports either E1 or ISDN PRI service. 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's on the front of the card display the type of service. There are two RJ45 modular
jacks on the face of the card. The settings for E1 or PRI service are selected by a bank of

button that will initialize the card manually if required. The RS232 DB 9 connector on the
