Planning for installation Standard 2.1
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 IP Adapter units. The Digital Telephone IP Adapter
unit communicates with the host PBX using the IP network. To use the Digital
Telephone IP Adapter 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 Digital Telephone IP Adapter unit to the IP network
!
assign a unique IP address and a subnet mask to the Digital Telephone IP
Adapter 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
→ Network Statistics.
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.
