Digital Data Calls
When ARS is used on the system, an account code can be entered
before or after dialing the telephone number.
If Forced Account Code Entry is assigned to the extension, the caller
must enter the code before dialing the ARS dial-out code.
Automatic Route Selection (ARS) checks Allowed and Disallowed Lists
before choosing the route for a call. This prevents users with restricted
extensions from dialing numbers that are not on an Allowed List. ARS
also prevents a user from dialing numbers on a Disallowed List.
An authorization code can be entered before dialing the ARS access
code. After dialing the ARS access code, you can enter an authorization
code only if a Feature button or programmed Authorization Code button
is used.
The ARS code can be programmed before a telephone number on an
Auto Dial button.
If ARS is used to make an outside call, the system selects another
line/trunk in the pool when the first line/trunk is in maintenance-busy
state.
When a call is made using ARS and all possible line/trunk routes are
busy, the call can be queued only for the first route in the pattern.
However, if the FRL for the extension does not allow the call to be made
over the route, the call is not queued.
If a voice call is queued for callback on a digital line/trunk pool, it can get
stuck in an infinite loop of queuing. The caller hears a continuous stutter
tone and cannot get rid of it. To avoid this situation, be certain to correctly
program the voice and/or data capabilities of pools of PRI and BRI
facilities in the ARS tables.
The use of ARS does not allow callers to avoid calling restrictions. The
system checks for outward or toll restrictions assigned to the extension or
barrier code before it selects the best route for making the call.
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 normally allowed to use
with pool dial-access restrictions.
Data calls can be made using ARS. To make calls using ARS, terminal
adapters and video systems simply dial the ARS dial out code (usually
followed by the telephone number. The data calls must be routed through
ARS pools that have only PRI, NI-1 BRI, and/or Switched 56 T1 data
lines. To make a 2B data call, a user must access two separate lines.
