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.

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
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.
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:
