FEATURE

‘upports both ,n-hook and off-hook call announcing from speakerphones

Enhanced secure off-hook voice announce operation

BENEFIT

With previous software, users were required to lift the handset of a speakerphone before they

could make a voice signalled intercom call. This software release allows a station user to perform either a on-hook or an-off-hook call announce from a speakerphone.

This software enhancement makes it possible for a station user to make a secure off-hook voice announcement (SOHVA) to a station that he or she is currently service observing. Although a programmer can disable the SOHVA feature when necessary, every DigiTech telephone can send and receive SOHVA calls as a system default, he or she must enable the service observe feature before a user can make use of it.

Expanded personal rlng tone choice

The system provides a group of distinctive tones for station ringing. A station user can choose a tone from this group to provide a distinctive ring at his or her telephone. Often when several telephones are located close to each other, each user chooses a different personal ring tone. Previous software provided four different tone choices. This software enhancement increases the distinctive ring choices to six. The personal ring tone choices now provided include the following

distinctive	tones:	4.1000/800	Hz	@ 23 Hz warble
1.666/571	Hz @ 16 Hz warble
2.1000/800	Hz @ 16 Hz warble	5.500/444	Hz @ 16 Hz warble
3.666/571	Hz @ 23 Hz warble	6.500/444	Hz	@ 23 Hz warble

Simplified hybrid operation

Enhanced automatic call back

In the past, the Federal Communications Commission (FCC) has required that telephone system manufacturers provide a hardware strap that installers could move to distinguish between hybrid system and key system operation. The DigiTech system provided this strap at either the Jl station connector or at a special terminal strip (depending upon the system model). The installer strapped two terminals together at either the 66M-xx station connector block or at the special terminal strip to select the hybrid mode. Recent rulings by the FCC have eliminated the need for the hardware strap. With this software release, whenever fh8 programmer assigns lines to Iin8 groups the DigiTech system automatically assumes fh8 hybrid mOd8. The hybrid system mode may still incur a higher monthly tariff to the tekphOn8 company; therefore, the FCC still requires that the installer report the equipment-type category designation number (KF for key system, MF for hybrid system) to the telephone company at the time of installation.

Prior to this software release, a station user could only camp on to a station that was busy on the intercom line. With this software release 11 a, a user can also camp on to a station after calling on the intercom line and receiving no answer.

Support for DlglTech telephones with a revlslon letter of I or later

With the release of the revision I models, Comdial has enhanced the design of the DigiTech telephones. These enhanced telephones require changes to the system software that this release provides.

All revision I DigiTech Telephones provide red, orange, and green light emitting diodes (LEDs). Red LEDs indicate which lines are in use at another station. Green LEDs indicate which lines are in use or on hold at a station. An orange LED indicates a ringing line thus distinguishing between lines that are on hold and a line that is ringing. Additionally, all revision I DigiTech telephones

provide pushbutton volume control on their front panels and a group listening feature. With group listening, a user can turn on the telephone speaker while the handset is off hook.

The 7700s~m 24-line, LCD speakerphone provides enhanced displays that prompt users on the operation of the many system features available to them. The LCD speakerphone provides three interactive buttons that provide quick easy access to system features and straight-fonnrard button programming without dialing codes. It also includes an auxiliary jack on the rear panel where the installer or the user can connect devices such as headsets, tape recorders, external ringers and external pagers.
