Remote Gateway 9150 Installation and Administration Guide 13
January 2005 Remote Gateway 9150 description
You must configure two security identifier passwords on the Remote
Gateway 9150 unit:
— inbound security identifier: This is the RLC’s security identifier. It is
presented on incoming calls.
— outbound security identifier: This is the Remote Gateway 9150 unit’s
security identifier. It is presented to the RLC on outgoing calls.
You must configure the same security identifiers in reverse on this Remote
Gateway 9150 unit’s RLC port.
Trunk connections
The Remote Gateway 9150 unit supports the following digital trunk
connections:
!
ISDN BRI from the Remote Gateway 9150 unit to the PSTN
!
ISDN PRI from the PSTN to the RLC at the host site
Multiple Subscriber Numbering (MSN)
Remote Gateway 9100 Series supports MSN. If the Central Office provides each
B-channel with a unique DN, then the first B-channel that you configure defines
the number for both B-channels.
Remote Gateway 9100 Series requires the ISDN numbers to be unique per
module for PSTN connections between the RLC and Remote Gateway 9150
unit.
Do not configure B-channels as Local and Remote if MSN is disabled.
For Remote Gateway 9150 units with multiple BRI modules:
!
Configure a maximum of one BRI module as Remote Only if PSTN
connections are required.
!
Configure all other BRI modules as Local only.
For Remote Gateway 9150 units with just one BRI module the BRI module can
be configured as Local only or Remote only. If local ISDN calls and remote
calls over PSTN are required, then MSN must be enabled.
