NOTE:
It is recommended that you do not administer extensions that begin
with
with
0
if the Uniform Dialing Plan is enabled. In the United States of
America,
0
is usually the attendant.
■
fac
(feature access code) only — a FAC can be any number from 1 to 9 and
contain up to 4 digits. You can use * or #, but only as a first digit.
It is recommended that a FAC be the last item entered in a row when mixed
numbering is used. Otherwise, problems may occur when 3-digit FACs and
4-digit extensions begin with the same first digit and the FAC is an
abbreviated dialing list access code.

The system requires that FACs for AAR and ARS have the longest length

for a first digit in the First Digit Table.
■
misc
(miscellaneous code) — these codes are used if you want to have
more than one kind of code start with the same digit and be the same
length. Misc can have a dialed length of 1, and can have a first digit of
length. Misc can have a dialed length of 1, and can have a first digit of
0
through
9
. Using
misc
requires that you also define a
Second Digit Table
.

pextension
—
Is made up of a prefix (first digit) that can be a
0
through
9
(* and # not allowed) and an extension number of up to five digits in length.
The maximum length of a prefix and extension combination is six digits.
When a prefixed extension is entered in the dial plan, a TAC cannot be
entered before the prefixed extension on the same row in the table. If a first
digit is already assigned as a TAC, a prefixed digit cannot be entered after
the TAC on the same row in the table.
The maximum length of a prefix and extension combination is six digits.
When a prefixed extension is entered in the dial plan, a TAC cannot be
entered before the prefixed extension on the same row in the table. If a first
digit is already assigned as a TAC, a prefixed digit cannot be entered after
the TAC on the same row in the table.
The purpose of the prefix is to identify the dial type as an extension. After
digit collection, the prefix digit is removed from the string of dialed digits.
The remaining digits (extension number) are then processed. A prefixed
extension allows the use of extensions numbers with any first digit (the
extension length must be specified on the table). The "prefixed extension"
cannot have the same first digit as the ARS or AAR facility access code
(FAC).

NOTE:
When a dial plan has mixed station numbering, extensions of various
lengths (all with the same first digit) are mapped on the First Digit
table as shown on Field descriptions for page 1. The system then
employs an inter-digit time-out to ensure that all dialed digits are
collected. The inter-digit time-out may add several seconds to the dial
time. An alternative to the delay required in the time-out mechanism
at the expense of dialing an extra digit is to use prefixed extensions in
the dial plan.
