Remote Gateway 9150 Installation and Administration Guide 75
January 2005 Planning for Remote Gateway 9150 unit installation
Deployment options
You can install and configure the RLC on the host PBX and Remote Gateway
9150 unit with the following network capabilities:
!
only the IP network (Voice over IP)
!
only the PSTN (for example, ISDN BRI trunks)
!
both networks (required for QoS Transitioning Technology functionality)
If you choose not to use both networks initially, this section suggests how you
can gradually phase in Voice over IP and QoS Transitioning Technology
functionality.
Port and station assignment
Regardless of which network you use initially to route calls, you must plan RLC
port and remote site user station assignments. Assign a single user at the Remote
Gateway 9150 site to one RLC port that you configure on the host PBX with
voice capability. This includes the analog port and the stations using ATAs.
Exception:.You must assign stations that use MCAs for data transmission to
ports that are configured on the host PBX with data capability.
If you plan to use the PSTN to route calls, one data port on the host PBX must be
dedicated to the Remote Gateway 9150 site to establish the call connections.
ATTENTION!
Even if you plan to route calls over the PSTN only, you
must assign an IP address and gateway to the Remote
Gateway 9150 unit and RLC to allow remote
administration.
