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.

INDEX OF NEW FEATURES (continued)
Keyset “Hot” Dial Pad Keys
There is a system-wide option that, if enabled, allows keyset users to dial line access codes and feature codes with-
out lifting the handset or pressing the SPKR or SPCL key. This programmable feature is called “hot dial pad” to
indicate that the dial pad keys are always activated. See pages 44,4-42, and 5-68.
Private Intercom Call Override
If a keyset station has the Private Intercom Override feature enabled, the user can place a handsfree call by press-
ing l or # when calling a keyset station that has handsfree mode disabled. See pages 4-56,5-30, and 5-52.
%ilent” u Tone Selection
When setting the ring tone on a keyset, the keyset user can enter 0 to disable ring tones. See page 4-48.
Toll Sew&y Feat= Set
The Extended software package now includes the following Toll Security features:
Weekly Toll Limits: When enabled, the weekly toll limit feature keeps track of the accumulated call cost for spe-
cified types of toll calls. The feature can monitor 7- and lOdigit toll calls and/or operator-assisted/international
calls. Alarm messages have been added for toll limit management. See pages 4-10,4-30,4-62,4-63,4-83,
4-1X2,4-125,5-97, and 6-8.
Inter-Tel Services: The weekly toll limit feature can only be enabled by Inter-Tel Services. See page 6-41.
Enhanced DISA Security Codes: DISA security codes can be 4-7 digits long. ADISA caller will have only three
opportunities to enter a valid security code. If the caller fails three times, the failure will generate a system alarm
and that trunk will be inoperable for five minutes. See pages 4-38,5-111,5-115, and 6-8.
DISA Toll Restriction: DISA lines can be given day and/or night mode toll restrictions like those for individual
stations (except LCR-Only). See pages 4-38,5-106,5-111, and 5-116.
SMDR Blocked DISA Calls Option: A programming flag has been added to SMDR that allows blocked DISA
calls to appear in the Sh4DR report. See pages 4-38,4-123, and 4-124.
DISA And Hunt Group Information In SMDA Summary Reports
DISAcall information has been added to the System Summary report and a new Hunt Croup option has been added
to the Summary Report. See pages 4-38,4-115,4-118, and 5-140.
End-Of-Dialing Digit Suppression
Display and Redial: A system programmin g flag allows the programmer to specify whether all dialed digits or
just the digits that make up the valid call are displayed and stored in the redial buffer. If desired, the “extra” digits
used for dial-up banking machine, voice mail, automated attendant, or other purposes canbe suppressed. Suppres-
sing the extra digits prevents entries, such as PIN numbers and other codes, from being displayed when they are
dialed. See pages 4-93 and 5-69.
SMDRReportsz A programming flag has been added to the SMDRreport programmingprompts that allows you
to specify whether all dialed digits or just the digits that make up the valid call appear in the SMDR report. See
pages 4-123 and 5-142.
Account Code Enhancements
LCR Toll Forced Account Code: Forced account codes for toll calls only can be programmed for stations with
LCR-Only toll restriction in day und night modes. When this account code type is enabled, the user only has to
enter an account code if the system detects that a toll call has been dialed whenLCR is used. See pages 4-33,4-66,
5-32, and 5-55.
Validated Forced Account Codes: Forced account codes can be validated or non-validated. See page 4=-66,5-32,
5-33, and 5-55.

INDEX OF NEW FEATURES (continued) ’
Voice Mail/Computer Enhancements
Do-Not-Disturb Breakthrough: Normally, calls to a station through DIM, the automated attendant, or a voice
computer are not blocked by placing the station in do-notdisturb. If desired, individual stations can be set to pre-
vent these calls from breaking through do-not-disturb. See pages 4-14,4-21,4-38,5-30, and 5-52.
Voice Mail/Computer Hunt Groups In All Software Packages: In any software package, any hunt group can be
designated as a voice computer hunt group. See pages 4-16,4-21, S-61, and 5-62.
Automated Attendant Hunt Groups: Voice computer hunt groups can be designated as automated attendant
hunt groups. See pages 4-21 and 5-63.
Dial RuleS: Voice mail/computer hunt groups can be assigned dial rules. See pages 4-21 and 5-63.
Recall Destination: Avoicc mail/computer hunt group can have an assigned recall destination. See pages 4-21
and 5-64.
Overflow/Announcement Stations: Voice mail/computer hunt groups can serve as overflow/announcement sta-
tions. See page 5-66.
DTMF Feedback Tones: The progress tones that are normally sent to a voice computer can be replaced with
-“feedback” tones that determine call status. See pages 4-21,5-31, and 5-52. If feedback tones are enabled,
the “extended” set of feedback tones can also be enabled in system-wide programming. See pages 5-67 and 5-68.
Allow Cross-Tenant Voice Mail/Computer ‘Itaffic: The Programmer can determine whether voice mail units
and voice mail computers will be allowed to place intercom calls, forward intercom calls, or transfer intercom or
outside calls to stations that are in different tenant groups. See pages 4-21 and 5-67.
Version Feature Code: When entered at a voice computer port this feature code generates a four-digit IYIMF
code that indicates the last four digits of the software part number. It is used by voice processing software to ensure
that the KSU software is compatible with the voice pro&sing features. See page 4-7.
Remote Hunt Group Remove/Replace
The Hunt Group Remove/Replace feature can be controlled from the attendant’s station using the Remote Hunt
Group Replace feature code. See pages 4-144-19, and 4-111.
Hunt Group Enhancements
There is a system option that can be enabled to send uZZ unanswered hunt group calls first to the announcement
station and then to the overflow station. See pages 4-17 and 5-68.
If a station that receives a recalling hunt group call chooses to transfer the call back to the hunt group, the call
retains its original queue position in the hunt group. Also, calls that go to the announcement and overflow stations
do not lose their places in the queue. While the call is at a playback device announcement or overflow station
(except voice compufer overflow/announcement stations) it continues to circulate through the hunt group. If a
hunt group member picks up the call, it is pulled back from a playback device overflow/announcement station and
connected to the hunt group station. See pages 4-18 and 4-19.
Station Off-Hook Alarm
The STXlTON OFF HOOK alarm now indicates the station that is off hook. Also, the alarm clears automatically
when the station user hangs up. See pages 4-1X2,4-125, and 6-8.
Equal Access “1OlXXXX” Numbers Supported
The system supports the “lo- and “1OXXX” equal access numbers. Toll restriction SCOS 7 has also been
modified to support equal access dialing. See pages 4-27,4-B, and 5-88, and 5-113.
Password Required
The password prompt will always appear when a programmer logs in to a programming session. In the default state
there is no database programming password and pressing RETURN will allow access to the database. See page
5-10.

FCC REGIJIAI’IONS
IMPORTANT:
1. This equipment complies with Part 68 of FCC rules.
On the back of the equipment cabinet is a label that
contains, among other information, the FCC regis-
tration number and ringer equivalence number
(BEN) for this equipment. Customers connecting
this equipment to the telephone network shall, be-
fore such connection is made, give notice to the tele-
phone company of the particular line(s) to which
such connection is to be made, and shall provide the
telephone company with the following information:
- Complies with Part 68 of FCC rules
- FCC registration number: BE2USA40751-
MF-E (for MF-rated systems) or BE2USA-
61845KF-E (for KF-rated systems)
- Quantities and USOC numbers of required inter-
face jacks (see chart on next page)
- Sequence in which trunks are to be connected
- Binger equivalence number (BEN) or service or-
der code (WC), as applicable, by position (see
chart on next page)
NOTE: The FEN is used to determine the quan-
tity of devices which may be connected to the
telephone line. Excessive RENs on the telephone
line may result in the devices not ringing in re-
sponse to an incoming call. In most, but not all
areas, the sum of the RENs should not exceed
five (5.0). To be certain of the number of devices
that may be connected to the line, as determined
by the total RENs, contact the telephone compa-
ny to determine the maximum BEN for the call-
ing area.
- Facility interface code (FIG) by position (see
chart on next page)
The telephone company should also be given notice
upon final disconnection of this equipment from the
particular line(s).
It is also the responsibility of the customer to provide
the telephone company with registration numbers of
any other devices which are configured for connec-
tion to the telephone network.
2. This equipment cannot be used on public coin ser-
vice provided by the telephone company. Connec-
3.

tact a local authorized factory service representative
for repairs and/or warranty information. The cus-
tomer, users, and unauthorized technicians should
not repair, make adjustments to, or attempt to ser-
vice this equipment in any way.
In the event of trouble with the telephone line(s), this
equipment must be disconnected from the telephone
line(s). If trouble ceases, the equipment must be re-
paired by an authorized factory service representa-
tive. If the trouble continues to occur with the
equipment disconnected, the telephone company
should be notified that they have a problem. If this is
the case, repairs or adjustments made by the tele-
phone company will be made at their expense.
Allowing this equipment to be operated in such a
manner as to not provide proper answer supervision
signaling is in violation of Part 68 of FCC rules. This
equipment returns answer supervision signals to the
public telephone network when: answered by the

1. INTRODUCTION 2. SYSTEM CAPACITIES
1.1 The 256 System is a state-of-the-art, digital, voi-
ce/data, hybrid telephone system. As a hybrid system, it
incorporates many of the user-tiendly features of key
systems with many of the expanded features and flexi-
bility of private branch exchange (PBX) systems.
1.2 The 256 System is designed to meet the needs of
growing businesses. In fact, the system’s unique struc-
ture (including digital signal processing) allows it to be
easily adapted and expanded as business communica-
tion needs change. The modular design makes the sys-
tem easy to install and service. And, the programmable
features provide an abundance of user-friendly applica-
tions to meet each customer’s needs. Highlights of the
system’s design include:
Advanced microprocessor technology.
Modular, easily replace-able hardware with add-on
capabilities for optional features.
Flexible programming to customize many system
and station features.
2.1 The equipment cabinet has 16 slots for station and
trunk cards. The actual number of stations and trunk
available depenak on the nwnber and type of cards, sta-
tion in&uznts, andpower supply motihles installed
2.2 For example, if all 16 cards are station cards, there
can be a maximum of 256 station instruments installed.
Or, if only one of the cards is a type of Keyset Card (re-
quired), four are Tl Cards (the maximum allowed), and
the other 11 are Loop/Ground Start Cards, the system
maximum is 16 stations (using digital keysets or using
g-line IMX AIM keysets, which can be installed two to a
circuit) and 184 trunks. Of course, in most circum-
stances, the maximums listed below will never be
reached due to the variety of cards and station instru-
ments installed.
23 A fully-equipped 256 System has the capacity for
up to:
- 256 Ports (16 available card slots with a maxi-
mum 16 circuits per card equals 256 ports.
Although it is theoretically possible to equip
more than 256 ports [e.g., using Tl Cards and/or
digital or 8-line IMX AIM keysets], the system
limits the number to 256. See page 2-6 for more
information.)

OVERVIEW INTER-TELPRACTICES
Issue 1, November 1994
IMWGMX 256 INSTALLATION & MAINTENANCE
- 216-220 Non-Blocking Voice Channels (The
exact number of voice channels available de-
pends on the number of DTMF decoders
installed in the system. The voice channels are
available for outside calls, intercom calls, and
paging on a first-come, first-served basis. See
page 2-6 for more information.)
- 184 Central Office (CO) Trunks (Loop start
and/or ground start trunks installed in increments
of up to eight or 24, depending on the number of
Loop/Ground Start Cards [LGCS], Loop Start
Cards [LsCs], and/or Tl Cards FlCs] installed
in the equipment cabinet. LGCs and LSCs can
have up to eight CO trunks installed, while TlCs
can have up to 24 CO trunk circuits installed.)
NOTE: The system is limited to a maximum of
four Tl Cards. (Pour cards with up to 24 circuits
per card equals 96 possible Tl trunk circuits.)
- 184 Direct Inward Dialing (DID) l’kunks
(Direct station access trunks installed in incre-
ments of up to eight or 24, depending on the num-
ber of Inward Dialing Cards [n>cs] and/or Tl
Cards installed in the equipment cabinet. IDCs
can have up to eight DID trunks installed, while
TlCs can have up to 24 DID trunk circuits
installed.)
- 140 E&M ‘Ihmks (Special “tie” trunks between
two supporting telephone systems [e.g., between
two 256 Systems] installed in increments of up to
four or 24, depending on the number of E&M
Cards WCs] and/or Tl Cards installed in the
equipment cabinet. EMCs can have up to four
E&M trunks installed, while TlCs can have up to
24 E&M trunk circuits installed.)
- 256 Stations (Combinations of keysets, DSS/
BLF Units, Attendant Computer Consoles, and
I
single-line sets in increments of up to eight or 16,
depending on the number of Digital Keyset
Cards [DKSCs], Keyset Cards PCs or KSC-
Ds], Single-Line Cards [SLCs], and/or Inward
Dialing Cards @DCs] installed in the equipment
cabinet. XSCs can have from eight to 16 stations
connected depending on the type of keysets
used, SLCs can have up to 16 stations connected,
and IDCs can have up to eight.)
INOTE: At least one DKSC,
KSC, or KSC-D
must be installed to provide an attendant
(equipped with a display keyset or an Attendant
Computer Console) to program selected system
data, act as the attendant for unsupervised CO re-
calls, receive system alarm messages, etc.
- SO Keyset Circuits Equipped With Direct Sta-
tion Selection/Busy Lamp Field @SS/BLF)
Units (Digital DSWBLF Units are physically at-
tached to and programmed to be used with spe-
cific digital keysets. Up to four units may be
attached to one keyset. The units are powered by
their own AC transformers and do not require a
DKSC circuit that is separate from the keyset’s
circuit. Analog keys&, analog DSS/BLP Units,
and Attendant Computer Consoles use separate
KSC or KSC-D circuits. For each analog DSS/
BLF Unit installed, one less analog keyset or At-
tendant Computer Console may be installed. Up
to four analog DSS/BLF Units may be connected
to a single Keyset Card, and as many units as de-
sired can be used with a single keyset. See page
2-27 for more information.)
3. SOFTWARE PACKAGES
3.1 The IMX 256 System is available in five software
“packages” (refer to REPLACEMENT PATnrs for the
part numbers). The customer can choose between one
KP-rated system and four MP-rated systems. The KP-
rated system permits only one trunk to be accessed per
trunk key, and users can access only one auto trunk and
only one trunk in each of the trunk groups. The MP-rated
systems permit one-key access to multiple outgoing
trunks. The five software packages are listed below.
