Interface Chan For TCP/IP, interface channel numbers are in the range 5000 
– 64500.
The recommended values are: 5001 for CMS, 5002 for Intuity 
AUDIX, and 5003 for DCS connections that are not 
gateways. These three values should be reused for multiple 
instances of these applications; for example, if there are two 
Intuity AUDIX’s, use 5002 for both; or if there are four 
DEFINITY ECS’s, use 5003 for all four. The combination of 
Link, Interface Channel, and Mach ID must be unique.
Destination Node Name of the far-end node for this channel. This must be a 
name entered on the Node Names screen.
Destination Port A value of 0 allows any available interface channel on the 
destination node to be used for this connection. The Interface 
Channel number on the Switch-3 Processor Channel screen 
must also be set to 0.
Session - Local For each connection, the Local Session number on this switch 
must equal the Remote Session number on the remote switch 
and vice versa. Session - Remote
Mach ID Destination switch ID identified on the dial plan of the 
destination switch.
Processor Channel 32: (The Ethernet side of the gateway)
Enable Set to y.
Appl. Use gtwy-tcp for conversion between X.25 and TCP/IP.
Gateway To Indicates a software connection between processor channels 
32 and 23.
Mode Node-1 is the “server” for this session. Set node-3 to “client” 
(c).
Interface Link This must match the link number assigned on the data module 
screen.
Interface Chan For TCP/IP, interface channel numbers are in the range 5000 
– 64500.
The recommended values are: 5001 for CMS, 5002 for Intuity 
AUDIX, and 5003 for DCS connections that are not 
gateways. The combination of Link, Interface Channel, and 
Mach ID must be unique.
The recommended values for gateway switches is 
6001–6099. The interface channel number must be unique for 
each gateway.
Destination Node Name of the far-end node for this channel. This must be a 
name entered on the Node Names screen. Field Conditions/Comments

between 1 and 256 (si model) or 384 (r model), but they 
must be consistent between endpoints. For each 
connection, the Local Session number on this switch must 
equal the Remote Session number on the remote switch and 
vice versa.

number for the Local and Remote Session numbers. It is 
allowed, but not recommended, to use the same Session 
numbers for two or more connections. Session - Remote

Switch 3 Task — Assign Node Names 
This task assigns node names and IP addresses to each node in the network. This 
screen is administered on Switch 3. A Node Names screen must be administered on 
each switch in the network.
The node names and IP addresses in any network should be assigned in a logical and 
consistent manner from the point of view of the whole network. These names and 
addresses should be assigned in the planning stages of the network and should be 
available from the customer system administrator or from a Lucent representative.
Note:Enter node names for Intuity AUDIX and MSA adjuncts on page 1. Enter 
node names for switches, routers, and CMS starting on page 2.

Subnet Mask Enter the subnet mask associated with the IP address for 
this IP interface. (The IP address is associated with the 
node name on the Node Names screen). 
In this example, leave the default subnet mask, 
255.255.255.0, which indicates no subnetting for a Class 
C IP address.
See the discussion of subnetting, Subnetting  (page 16), in 
Chapter 1 and Configuration 1: R8r  R8si  
(page 60) in this chapter for details about subnet masks.
Gateway Addr Leave blank for this configuration. The only connection 
to this IP interface is node-1 on Switch 1. Node-1 is on 
the same subnetwork as this IP interface, so no gateway is 
needed.
In general, for connectivity to other (sub)networks, enter 
the address of a network node that will serve as the 
default gateway to the other (sub)networks.
