108 RLC Installation and Administration Guide
Configuring the host PBX for the RLC Standard 4.0
Configuring the host trunk for a Remote
Gateway 9150 unit
Remote Gateway 9150 units require an end-to-end digital connection. Tell your
service provider which type of ISDN connection (PRI or BRI) that you need for
your remote service equipment. Nortel recommends ISDN PRI trunks for
connecting the CO to the host PBX. Tell your service provider the parameters to
configure on the trunk according to the features that you want on the devices at
your remote location.
ISDN PRI configuration
ISDN PRI trunks transport Remote Gateway 9150 unit calls between the host
PBX and the PSTN. To ensure full functionality for all remote sites served by
each RLC, ask your service provider to configure the following elements on
each trunk:
„
two-way voice and two-way data capability
„
caller ID
„
end-to-end digital circuitry, no analog segments (confirm this with both
long-distance and local service providers)
„
non-blocking configuration (ensure that configuration will not block
remote site traffic)
„
56K or 64K clear channel, according to your equipment
ISDN BRI configuration
Some locations require ISDN BRI service from the host PBX (the host trunk
connection) instead of PRI for geographical reasons. ISDN BRI configuration is
identical to ISDN PRI configuration. Verify this with your service provider. For
information about ordering BRI service, refer to the
Remote Gateway 9100
Series Network Engineering Guidelines (NTP 555-8421-103). For information
on how to obtain this document, refer to “Related information products” on page
xxii.
Note: In North America, an ISDN BRI line can only be ordered as a subscriber
line and is not a valid trunk option.
