Customers upgrading to Communication Manager can choose to migrate to the
6-digit or 7-digit dial plan or not. Customers who choose not to migrate may
convert their dial plans at a later date.
Distributed Communications System (DCS) protocol is limited to a dial plan of
3-5 digits, so if your dial plan requires 6 or 7 digits, QSIG — which is the generic
name for a family of signaling protocols— is required.
Punctuation on station displays
On digital telephone displays, Communication Manager can display punctuation
to make reading a 6-digit or 7-digit extension easier. The number of digits plus
punctuation that can be displayed cannot exceed eight characters.
Punctuation marks that are allowed include:
■ hyphen (for example, xxx-xxxx)
■ period (for example, xxx.xxxx)
■ space (for example, xx xx xx)
Formats for displaying numbers with punctuation are on the dial plan parameter
form.
■ the default 6-digit extension display format is xx.xx.xx
■ the default 7-digit extension display format is xxx-xxxx
For more information on the dial plan parameter form, see the Administrator’s
Guide for Avaya™ Communication Manager, 555-233-506.
Extended trunk access
Used with Uniform Dial Plan, allows the system to send any unrecognized
number (such as an extension not administered locally) to another system for
analysis and routing. Such unrecognized numbers can be Facility Access Codes,
Trunk Access Codes, or extensions that are not in the Uniform Dial Plan table.
Non-Uniform Dial Plan numbers are administered on either the First Digit Table
(on the Dial Plan Record form) or the Second Digit Table. They are not
administered on the Extended Trunk Access Call Screening Table. Extended
Trunk Access helps you make full use of automatic routing and Uniform Dial
Plan.
Extension Number Portability — When employees move within the network, they
can retain their extension numbers. The ability to keep extension numbers, and
even Electronic Tandem Network and Direct Inward Dialed numbers, when
moving to other locations within the company eliminates missed calls and saves
valuable time.
