The LED next to a DSS button for the ARS code is always off.
System Directory and Personal Directory (MLX-20L telephones only)
numbers can include the ARS dial-out code.
Only the ARS dial-out code and the dialed number are displayed. Digits
added by ARS before the dialed number and digits ignored by ARS are
not displayed. The digit
line.
When the ARS code is dialed before the telephone number, ARS can
select the facility on which to forward calls to an outside telephone
number. The FRL for the call is that of the extension from which calls are
being forwarded.
HotLine extensions (Release 5.0 and later systems) can use the ARS
access code if it is programmed into their Personal Speed Dial number.
When Night Service with Outward Restriction is programmed, enter the
password before dialing the ARS dial-out code, unless either the
extension is assigned to an Exclusion List or the number is on the Night
Service Emergency Numbers List.
ARS ensures appropriate and cost-effective use of pools. ARS and the
dial-access-to-pools restriction function independently of each other. If
ARS restrictions are programmed to allow access to a pool, a user may
seize a pool that the extension is not allowed to use under existing pool
dial-access restrictions.
An incoming call can access Automatic Route Selection (ARS) only
through Remote Access, transferring, or Remote Call Forwarding through
ARS. A PRI line can be a member of a pool accessed through ARS.
Before ARS routes a call to a pool, it checks whether one or more
member lines in that pool are available. If not, it selects an alternative
pool so that the call is not blocked. Even if a B-channel is available when
ARS selects a pool with an available line, there may be none available
when it is time to send a setup message to the network. Or, after the
setup message is sent, the network may determine that the B-channel
proposed by the system is not available. In either case, the call fails and
fast busy tone is heard.
In systems prior to Release 2.0, Recall cannot be used to hold an outside
line if ARS has been used to make the call. In Release 2.0 and later
systems, Recall can be used with calls made through ARS.
Remote access users can make calls using ARS by dialing into the
system, entering a barrier code if required, and dialing the ARS code
while listening to the system dial tone. Facility Restriction Levels (FRLs)
can be assigned to restrict the routes that remote callers can use. When
barrier codes are not used, FRLs are assigned to all remote access
lines/trunks. When barrier codes are used, FRLs are assigned to
individual barrier codes.
The ARS dial-out code is saved with the telephone number dialed.
