Comdial Impact Dsu Instructions Manual

							Recognizing Radio Frequency Interference
The electronic key system contains incidental radio frequency generating circuitry and, if not installed and used
properly, may cause interference to radio and television reception. This equipment has been tested and found to
comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules. These limits
are designed to provide reasonable protection against such interference when operated in a commercial environment.
Operation of this equipment in a residential area may cause interference to radio and television reception; in which
case the user is encouraged to take whatever measures may be required to correct the interference. If this equipment
does cause interference to radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient the
television or radio’s receiving antenna, and/or relocate the DSU, the individual telephone stations, and the radio or
TV with respect to each other. If necessary, the user should consult the manufacturer or an experienced
radio/television technician for additional suggestions.  The user may find the following booklet prepared by the
Federal Communications Commission helpful: “How to Identify and Resolve Radio-TV Interference Problems.”
This booklet is available from the Government Printing Office, Washington D.C. 20402. Stock No.
004-000-00345-4.
This equipment has been tested and found to comply with the limits of a Class A digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated  in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
This digital apparatus does not exceed the (Class A) limits for radio noise emissions from digital apparatus set out in
the Radio Interference Regulations of the Canadian Department of Communications.
Le pre’sent appareil nume’rique n’emet pes de bruits radioe’lectriques de’passant les limites applicables aux
appareils nume’riques (de la class A) prescrites dans le Re’glement sur le brouillage radioe’lectrique e’dicte’ par le
ministe’re des Communications du Canada.
CAUTION
Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
Determining The Ringer Equivalence Number
The REN of each line is 1.3B. The FCC requires the installer to determine the total REN for each line, and record it
at the equipment.

							3.1 Using Chapter Three
Since Chapter 3 deals only with the programming of the system, each programming step
includes only a brief explanation of that feature. Therefore, before you begin programming the
system, familiarize yourself with all of the system’s features that are discussed in Appendix A.
By doing so, you can be certain that you are programming what the customer wants.
NOTE: Prior to taking any programming action, determine all desired parameters and
requirements. Record this data on the programming reference tables provided in
Chapter 4.
3.2 Understanding System Programming
While the Digital Telephone System offers many functional possibilities, it is your programming
that determines the system’s operation. You can program the system in two ways: using a
telephone, or using a Video Display Terminal (VDT).
3.2.1 Using A Telephone To Program The System
Perform Class of Service configuration programming from station port 10 or station port 12. The
system will not accept programming commands from any other station port in the system. For
best programming results, use an LCD speakerphone and a DSS/BLF console at station port 11
or 13 to see which features are assigned to individual stations. While you can install any
non-LCD digital telephone and use it for programming, visual feedback of the programming
operations will not be available. You must always keep the handset of the LCD speakerphone
on-hook while you use this telephone to program the system.
NOTE: Be sure the system is not in the night transfer (of ringing) mode of operation when
you perform the programming steps.

							3.2.2 Supporting DigiTech Telephones (Revision I And Later)
There are several items that you need to consider when connecting revision I and later DigiTech
telephones to the digital telephone system:
·While the system software cartridge (product code Snnnn) with software release 11A and
later supports the use of all DigiTech telephones regardless of their revision letter, any
systems with a software release of 9 or earlier will not support the revision I and later
telephones. In other words, whenever a system includes revision I or later telephones, be
sure that the system software cartridge has a software release revision of 11A or later.
·Always program station ports to provide ringing line preference to revision I and later
DigiTech telephones (and to allImpacttelephones) that are connected there. This action is
necessary before the orange LED feature can become active. The orange status light
indicates a ringing line to distinguish it from lines that are in use or on hold.
