Pre-Release 11 Link Administration Instructions
226 Installation Guide
● The DLG should be on its own separate LAN segment. To effect this, you will need two
Network Interface Cards (NICs) in the Avaya CT Server, one for client access and one
for the connection between the DLG and the DEFINITY G3 PBX Driver.
IP Addresses
It is strongly recommended that you use at least two IP addresses.
● IP address for the DLG.
Make certain that you have the IP address or the DLG or its host name (if host names
are used instead of IP addresses). See the DEFINITY switch administrator.
If you are using a separate LAN for your DLG (recommended) and all links go to a
single switch, then you can use the default IP address, which is 192.168.25.10.
● IP Address for the DEFINITY G3 PBX Driver,
Verify that you have a local IP address for the DEFINITY G3 PBX Driver on your
Telephony Server. You will need this IP address for installing the DEFINITY G3 PBX
Driver. You may obtain this address from the network administrator or you may use the
default address provided in the installation program (192.168.25.20) if you have a
private LAN (as recommended) between the Telephony Server and the DEFINITY
ECS switch. This local IP address should be different from the IP address used for the
Avaya CT server, as recommended.
Client LAN Segment
See Chapter 4: Installing Avaya Computer Telephony TSAPI Client Software for more
information about client-based Avaya CT requirements.
Guidelines for Setting Up a Private LAN
Follow these guidelines for implementing a private LAN for Avaya CT.
● Use IP addresses within the following ranges:
- 10.0.0.0 — 10.255.255.255
- 172.16.0.0 — 172.31.255.255
- 192.168.0.0 — 192.168.255.255
If You Intend to Use Host Names
You have the option of using host names, instead of IP addresses, when administering the
DEFINITY LAN Gateway and the DEFINITY G3 PBX Driver. If you use host names instead
of IP addresses, each entry in the HOSTS file provides information about one host on the
IP network. The DEFINITY LAN Gateway link connection is considered a host.
