I
IMX
And GMX Combined Into One Manual
with
the new 1995 North American Numbering Plan software releases, the IMX 256 and GMX-256 products are
identical except for the station instruments that can be installed on them. To provide better service, condense refer-
ence materials, streamline training, and facilitate technical support, the installation manuals for the two systems
have been combined into one generic manual. When using this combined manual to help sell, install, or service a
particular system, be aware that not all of the station instruments described in this manual are available on both
products. See page 2-2 for a list of the station instruments that can be installed on each product.
North American Numbering Plan
(NANP)
The growth of telecommunications services has created an increasing demand for more telephone
numbers.
To
meet the demand,
Bellcore
has prepared a long-range North American Numbering Plan (NANP) to provide addi-
tional telephone numbers. The plan expands the capacity of the current numbering system by making area and
office codes interchangeable. That is, numbering patterns formerly reserved for office codes can be used as new
area codes and office codes within existing area codes can have the same pattern as other area codes. This version
of software supports the new numbering plan. See pages
4-28
and 5-90.
Home And Local Area Codes
In many areas, the telephone company has created call-cost arrangements that refer to “home” and “local” area
codes. The home area code is the area code within which the system resides. The local area codes are additional
area codes that, when called, use the local or toll local call-cost rate instead of the long distance rate. Up to three
local area codes can be programmed and then extended within toll restriction progxamming to provide proper call
costing. See pages 4-29 and 5-171.
Loop Start
‘Ikunk
Glare Protection
During a “glare” connection, the software now allows the incoming call to remain connected, while still protecting
against possible toll fraud. See pages 2-14 and
5-68.
Station Exchange
This programmable station feature allows a station user to exchange the extension numbers of two station circuits.
This swaps the database and user programmed features of the extension numbers between two station circuits
without the need for database programmin
g.
The circuit number of the station locations are unchanged, but the
extension numbers are changed. See pages 4-99 and 5-31.
Digital Cards, Diil
Keysets,
and
Diiti
DSWBLF
Units
The IMX 256 System can now support the digital station instruments originally designed for the Inter-Tel Axxess
System. See pages
2-2,2-g,
2-12,2-13,2-21
to
2-27,2-33,2-34,2-44,3-7,3-22,3-28,3-29,347,3-48,
3-62 to
3-70,3-90,3-91,4-21,4-40,4-50,5-24,547,5-135,6-3,7-1,
and 7-3.
All digital keysets utilize DSP shared resources for speakerphones, and Executive Digital Keysets have enhanced
displays. See pages 2-22,440, and 4-41.
APC Data Port Module (PCDPM) must be installed on digital keysets to provide the secondary voice path needed
for the
OIWA
feature. See pages
2-23,3-66,
and 4-61.
A
customer-provided, modem-equipped data device may be attached to any digital keyset with a PC Data
Port
Module (PCDPM) and a Modem Data Port module (MDPM) installed. See pages
2-23,3-70,
and 4-101.
Feature And Speed-Dial Keys On
DSWBLF
Units
DSS/BLF Units can have feature keys or system speed-dial keys programmed in their keymaps. See pages 4-50,
4-87, and 5-50.
