Description Of System Feat!

activated when station port 17 rings or when ringing iS sent to the paging port.

When programmed for station port 7 7 ringing, an external device is often used to provide loud ringing. When programmed for paging port ringing, an external paging amplifier is usually employed. The system supplies ringing tones to the paging port along with the relay closures. The ringing tones can be sent to the input of an external paging amplifier. The relay closures can be employed to energize the paging amplifier while the ringing tone is being sent to it.

System class of service programming is used to choose either the paging port. or station port 17 for the ringing port relay control. System class of service also determines the type of ringing sent to the paging port. Station class of service programming determines the type of ringing sent to station port 17. Also refer to the discussions titled: Common Audible Ringer /fIrerfaCe and External Paging Interface.

loss. The switching and charge circuitry are in the common equipment, while batteries, chassis, and cable are packaged as a separate option. When plugged into an active AC power source the common equipment will constantly charge the attached batteries. Built-in circuitry automatically switches to battery power when AC power is lost. Wrth batteries at full charge, a fully loaded system will operate for a minimum of one hour without AC power.

BLOCK PROGRAMMING

A class of service assigned to a particular station or line can be assigned to an entire block of stations or lines with one programming action. This feature eliminates the need to individually program stations and lines wfth the same class of service. Block programming class of service can be performed after a station class of service or line class of service has been programmed for a particular station or line.

BACKGROUND MUSIC EXTERNAL

MUSIC SOURCE RE 6 UIRED)

If an external music source is provided, background music can be turned on and off at individual stations. The loudness of the background music is adjusted with the call monitor speaker volume control, and the background music automatically turns off during calls. No class of service programming is required to provide this feature. Also refer to the discussion titled: External Music Source.

BASIC KEY SERVICE (lA2) EMULATION

The system provides all of the basic, 1 A24ype, button service features. These features are: selective line pickup, common line pickup, muftiline pickup, and hold. No special class of service programming is required.

BATTERY BACK-UP

(CHASSIS, CABLE, AND BATTERIES)

Battery back-up assemblies including chassis, cable, fuses, and batteries are offered as optional kits (available from Comdial). The assemblies are designed to connect directly to the unintenuptable power source (UPS) interface located on the common equipment chassis. No user intervention is required with this feature, and no class of service programming is required.

BAlTERY BACK-UP INTERFACE

Provision has been made for attaching a Comdial provided optional battery back-up kt to give full uninterrupted system power in case of an AC power

CALL ANNOUNCE WITH HANDSFREE

ANSWERBACK

The internal speaker at each station provides call-announce capability over the intercom link. A handsfree response to a call-announce call can be made. This response is transmitted by the microphone built into the telephone housing..

CALL COSTING AND STATION MESSAGE DETAIL ACCOUNTING REPORTS

The system provides buift-in, estimated costing of all outside calls. tt also provides station message detail accounting (SMDA) printout reports of all costed calls as well as displayed call costs on LCD speakerphones.

Call costing, in general, provides a means of’ establishing costs to be applied to outside calls made from system telephones. Call costing computes charges for a call after it is completed. lt does not restrict dialing as toll restriction does. Call costs are based on a two-tier time rate and includes a line surcharge cost. Allowances can be programmed for call set-up and minimum call duration. The system provides several ways of determining call costing making it is possible to apply reasonable rates for the entire country.

The system is arranged to automatically provide a report whenever the costed call storage reaches 95 percent of capactty. Additionally, programming can be effected that causes these reports to be printed automatically at a specific time of day.

There are five different SMDA reports which can be produced:
