Tepri Card - Samsung iDCS 500 Manual

TEPRI CARD

The TEPRI card installs in slots 1, 2 or 3 of any cabinet. The iDCS 500 TEPRI 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. The first TEPRI card installed in the iDCS 500 is the primary source of external clocking. The
second TEPRI installed is the secondary source of external clocking. Clock selection is first cabinet, left
to right then second cabinet, left to right. The primary and secondary clock sources should be
mounted in the bottom 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 top one is labelled T1, but is the socket
to use for PRI. The PRI software supports ETSI ISDN only. The bottom RJ45 socket can be used for E1
connections. However the T1 (PRI) RJ45 can be also be used for E1 connections and this is
recommended. E1 service selection is achieved via dip switch settings. Refer to the Chapter 5 for
PRI/E1 connection details.
The settings for E1 or PRI service are selected by a bank of dip switches as defined below (see Figure
3–19). To access the dip switches you must remove the case by removing the 4 screws (see Figure 3–
20) and splitting the case.
A maximum of 9 TEPRI cards can be provided per system (3 per cabinet). Push firmly in the middle of
both card ejectors on each card to ensure that it is fully inserted into the back plane connector.
The TEPRI card has a recessed RESET button that will initialize the card manually if required.
The RS232 DB 9 connector on the face of the TEPRI card allows trace monitoring of the TEPRI
functions. This is used for testing purposes and only to be used under the supervision of Samsung
Technical Support.
NOTE: Do not insert this card with system power ON.
