memory circuitry. If the DBM card is separated from the MCP card, all of the stored
information on the card is lost.
The generic feature software and feature authorization information is installed and
updated into the IMC8 flash card using the FMprog PC-utility. Similarly, the system
database is regularly backed up to, and may be transferred and restored from, an IMC8
flash card housed in the IMC8 flash card drive.
The Program Interface Facility
The PI (Program Interface) and CoralVIEW CVA/CVD provides a text-based facility
for reviewing and changing the system configuration and database. It enables the
performance and monitor of diagnostic routines. The PI can be accessed either via a
simple data terminal or by a personal computer.
The PI and CoralVIEW CVA/CVD/CVT can be accessed via an RS-232E data
terminal port (KB0) provided on the MCB Office front panel. See
Figure 8-2 .

The embedded Universal GateWay (UGW) circuit provides the Coral IPx Office
system with the ability to connect to the IP World. All Coral IP stations
(FlexSet-IP 280S, FlexIP SoftPhone, SIP) and external telephony gateways (Coral
Teleport for analog SLTs and Loop-Start/Ground-Start trunks) receive their Coral
signalling from the UGW circuit.
The UGW is the main Coral gateway to services offered on the enterprise network.
Voice calls maintained therein, although controlled by the Coral, are carried out
entirely on the network when both ports involved are IP ports, thereby allowing heavy
traffic configurations.
The UGW circuit is a Coral integrated gateway for IP phones, trunks and keysets
(SLTs and trunks require a Coral Teleport). It provides the capacity to drive up to 240
Coral IP ports, regardless of their physical location, and provides full Coral services
to these sets.
Certain Coral features require the intervention of the Media Resources Card (MRC).
The MRC is mounted on the MCB Office in piggyback fashion. It provides media
channels used to convert PCM calls to IP Packets and vice versa. Media channels are
also needed when one of the calling parties is not an IP host. No media channels are
needed for pure IP-to-IP connections (direct-connects). See
MRC Card, page 8-29
for
further information.
