Planning Form Instructions Continued
Record the information on the appropriate Data Form (2a or 2b) for each
data station and for each modem and ISDN 7500B Data Module included in
a modem pool or used to communicate with a local host computer or with a
workstation on a LAN:
1. In the "Logical ID" space write the logical ID for each station.
2. In the "Extension No." space, write the extension number for each station.
3. In the "Person or Location" space, write the name of the person or the
location of the data equipment.
4. Under the "Data Station Use" heading, check the "Individual use," "local
host computer," or "LAN workstation" box to indicate the use for the data
station.
Each analog or digital data station (including an analog data station connected
to an MLX telephone via an MFM) and each modem or ISDN 7500B Data
Module pair is treated by the system as a multibutton telephone with 34 buttons.
When you choose the mode of operation (Key, Behind Switch, or Hybrid/PBX),
Intercom or System Access buttons are automatically assigned to every station
connected to the control unit. However, you can customize the system by
changing the factory-set assignments and reassigning line buttons. The number
and types of buttons assigned depends on the mode chosen and the type of
station jack you are using.
The line buttons you can assign to data stations are
System Access Ring— used to make and receive inside and outside data
calls. To make outside calls, the user selects an outside trunk by dialing
either the code for Automatic Route Selection (ARS) or the dial-out code for
the trunk pool. Users at digital data stations can also dial the trunk number
(801-880) to select an outside trunk.
System Access Originate Only— used only to make inside and outside
calls. Calls are not received on this button so that the data user always has a
line available to make data calls. To make outside calls, the user selects an
outside trunk by dialing either the code for ARS or the dial-out code for a
trunk pool. Users at digital data stations can also dial the trunk number
(801-880) to select an outside trunk.
Personal Line— used to make and receive outside data calls from a data
station on a specific outside trunk. A personal line is an outside trunk
assigned to a line button on one or more data or voice stations. The outside
trunk cannot be a member of a trunk pool. To dedicate an outside trunk for
data calls and have the calls automatically answered at a data station, do not
assign the same outside trunk to both data stations and telephones because
modems answer voice calls as data calls.
On analog data stations, the personal line can be used to receive incoming
calls. You can use the personal line for outgoing calls by selecting the line
button on the analog multiline telephone, dialing on the analog multiline
telephone, and then activating the modem connected through a GPA.
