Extensions which have account code operation set up but no valid account pin is entered will be
assigned call barring class 4. This means incoming calls will be accepted but only emergency numbers
and numbers found in the exempt table may be dialled. In order to dial other numbers the user must
dial the account PIN code before the telephone number. System speed dial numbers are exempt
from call bar checking after the account pin has been entered.
Default
No extensions use call accounting and no accounts are set up.

Alternative Carrier Selection (ACS)
Default
No calls are routed via alternative carriers. All carrier details
are blank.
Description
ACS allows four alternative carriers to be used for external
calls in addition to the standard network. The carrier is
selected using three programmable values as follows:
Four alternative carriers may be programmed, each
with an access code of up to 9 digits.
An optional authorisation code may be programmed
with up to ten digits for each of the four alternative
carriers.
An optional pause of 0-9 seconds may be
programmed between dialling the carrier access code,
authorization code and the dialled telephone number,
if required by the network.
Alternative carrier selection works in the following way:
If an alternative carrier is enabled and active for the time of
day then the full external number is compared against an
exempt table. The exempt table contains 40 entries of 1-4
digits. If the digit(s) of any exempt table entry match the
start of the dialled digits then the call will not be sent via an
alternative carrier. This allows local numbers, freephone
numbers and other network specific numbers to be
excluded from ACS. A number in the exempt table will
never be sent via ACS, regardless of the other settings. The
figure opposite shows the procedure used by the system to
route calls via an alternative carrier.
The time and day method of carrier selection works by
allowing or clearing an alternative carrier for the peak time
and off-peak time period of every day. The peak time
period is separately programmed between any two hours of
