Planning for installation

Network considerations

Refer to the Remote Gateway 9100 Series Network Engineering Guidelines
(NTP 555-8421-103) for detailed information on planning and preparing your
network for the addition of Remote Gateway 9100 Series units. The Remote
Gateway 911x series unit communicates with the host PBX using either the
PSTN and/or IP networks. To use the Remote Gateway 911x series 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, you must:
physically connect the Remote Gateway 911x series unit to the IP network
assign a unique IP address and a subnet mask to the Remote Gateway 911x
series unit, unless using Dynamic Host Configuration Protocol (DHCP)
Note: Similarly, you must assign a subnet mask, gateway, and unique IP
address to the RLC on the host PBX.
have the ability to send and receive traffic to and from the RLC on the host
PBX

Determining DHCP assigned IP addresses

If you use DHCP at the remote location, determine the Remote Gateway 9100
Series unit's IP address by checking the Network statistics for the RLC through
Configuration Manager. Log onto Configuration Manager, choose the RLC as
the Device Type, and then access Alarms/Stats/Logs
Enter the Unit ID of the Remote Gateway 9100 Series unit that you want to
review the statistics for. The DHCP assigned IP address displays at the top of the
window.
Note: If you are using a Network Address Translation (NAT) router at the
remote location, the IP address provided is a NAT address. To access the Remote
Gateway 9100 Series unit using Telnet, ensure that the NAT router allows Telnet
access to TCP port 23, and for upgrades, TCP port 69.
