Ars Facility Restriction Level; System Speed Dial Codes - AT&T MERLIN LEGEND Release 3.1 System Planning Manual

Assigning Features to Data Stations

ARS Facility Restriction Level

Use these instructions only if the system is operating in Hybrid/PBX mode.
If the system uses ARS for data calls, you can assign a Facility Restriction Level
(FRL) to each data station. This value (from 0 to 6) corresponds to the FRL
assigned to each route and is used to restrict data users from access to
specific routes. Before restricting a data station, review the values assigned to
each route.
To restrict a data station from specific routes, assign an FRL value lower than
the route's lowest value. (Values equal to or greater than the route's values allow
data extension users to access those routes.) A value of 0 is the most restrictive,
and a value of 6 is the least restrictive. The factory setting is 3.
For example, to give an modem data station unlimited use of any ARS route,
assign a value of 6. If you have ISDN terminal adapter data stations, assign a
value of 0 to prevent users from inadvertently using ARS to select an analog line
for outside data calls.
Planning Form Instructions
1. Using Form 3f, Automatic Route Selection Tables and Form 3g,
Automatic Route Selection Default and Special Numbers Table, review
the values assigned to the routes.
2. In the Optional Features section of Data Form 1a or 1b for each data
station to record your decisions about Facility Restriction Level, do one of
the following:
Check 3 to keep the factory setting.
Write the value (0 to 6) for the ARS Facility Restriction level you want
to assign to each data station.

System Speed Dial Codes

To avoid giving the telephone number of a remote computer to modem pool
users, assign a System Speed Dial code to the telephone number. Users can
dial this 3-digit code to place data calls to the remote computer.
For data calls, the telephone number programmed for a System Speed Dial
code must include the access code (the dial-out code or the ARS dial-out code)
if required.
To specify that the remote computer's telephone number does not appear on
call reports, use the System Speed Dial instructions in Chapter 4 of this book.
