Lan Workstations - AT&T MERLIN LEGEND Release 3.1 System Planning Manual

Assigning Extension Jacks
If you have a limited number of ISDN terminal adapters or modems to share
among many users, assign some or all of the modems or ISDN terminal
adapters to a DHG. In this way, users can access all the devices in the DHG by
dialing one extension number.
Users access the computer by placing a data call to the extension number for
either an ISDN terminal adapter or modem (or DHG) depending on the user's
type of data station that is assigned for communication with the local host
computer.

LAN Workstations

A Local Area Network (LAN) consists of workstations (PCs) connected together
to share resources. The system connects to the LAN through a workstation that
functions as a gateway, providing ports for modem and ISDN terminal adapter
connections.
Assign each ISDN terminal adapter used for access to a LAN workstation to a
digital jack on an 008 MLX or 408 GS/LS-MLX module. Each modem must be
connected to a basic telephone extension jack on an 012, 016, or 008 OPT
module.

among many users, assign some or all of the modems or ISDN terminal
adapters to a DHG. In this way, users can access all the devices in the DHG by
