January 2005 Planning for Remote Gateway 9150 unit installation
Network considerations
The Remote Gateway 9150 unit communicates through both the IP and
telecommunications network using a host PBX.
To use the Remote Gateway 9150 unit in these networks, you must consider the
issues described in this section.
IP addressing and routing
To place and receive calls over the IP network, the Remote Gateway 9150 unit
must have:
!
a physical connection to the IP network
!
a unique IP address, default gateway, and subnet mask
Note: Similarly, you must assign a unique IP address, default gateway, and
subnet mask to the RLC on the host PBX.
In addition, the Remote Gateway 9150 unit must be able to send and receive
traffic to and from the RLC on the host PBX.
