Valid entries Usage
attd Attendant — Defines how users call an attendant. Attendant access
numbers can start with any number from 0 to 9 and contain 1 or 2
digits. If a telephone's COR restricts the user from originating calls,
this user cannot access the attendant using this code. Beginning with
the November 2003 release of Communication Manager (2.0), you
can also administer the attendant access code by entering an
appropriate fac or dac entry on the Dial Plan Analysis screen, and
then entering the actual access code on the Feature Access Codes
screen. Location-specific attendant access codes can be
administered on the Locations screen.
dac Dial access code — Allows you to use trunk access codes (TAC) and
feature access codes (FAC) in the same range. Dial access codes
can start with any number from 0 to 9, * or # and can contain up to
4 digits.
If an extension entry and a DAC entry have the same Dialed String,
the extension entry can be longer than the DAC entry only if all of the
trunk groups covered by that DAC entry have Dial Access on the
Trunk Group screen set to "no."
You can use the DAC to activate or deactivate a Communication
Manager feature or to seize a trunk from a trunk group, or both. In the
first case, the DAC functions as a FAC, in the second as a TAC. For
example, you can define the group 300 to 399 for dial access codes,
and allow both FAC and TAC in that range.
You can use 4-digit DACs for ordinary trunk access, but they do not
work for attendant control of trunk groups, trunk-ID buttons, or DCS,
and only the last 3 digits of the codes can be recorded in CDR
records. See also the description below for fac.
ext Primary extension — Defines extension ranges that can be used on
your system. Extension can have a first digit of 0 through 9 and can
be 1 to 7 digits in length. Extension cannot have the same first digit as
a 1-digit ARS or AAR feature access code (FAC). When a dial plan
has mixed station numbering, extensions of various lengths (all with
the same first digit) are mapped on the Dial Plan Analysis table. The
system then employs an inter-digit time-out to ensure that all dialed
digits are collected.
