3 CO line circuits for the three CO lines
7 digital telephone circuits
one for each of the five digital telephones;
the PDIU-DIs do not require dedicated cir-
cuits.
one for a digital door phone/lock control unit
to support a door phone
one for the PDIU-DS connected to the mo-
dem
2 standard telephone circuits
one for the modem
one for the facsimilie machine
A music source for Music-on-hold and Back-
ground music can be connected to the Key
Service Unit MOH RCA jacks.
5.23 Conclusion. Several optional PCBs in addi-
tion to the Key Service unit would be needed for the
application. Two CO line circuits and four digital
telephone circuits would be provided by the KSU.
The third CO line circuit, as well as two digital
telephone circuits would be provided by an op-
tional QCDU. A second QCDU would be neces-
sary to provide the seventh digital telephone cir-
cuit. An optional QSTU would provide the two
standard telephone circuits. An optional QRCU
would be needed for the Dual-tone Multi-frequency
(DTMF) tones generated by the devices (modem
and facsimilie machine) connected to the standard
telephone lines.
5.30 The following provides an examples of how to
configure a STRATA DK16.
5.40 Strata DK16 - Example 1 (Bank)
5.41 Customer Requirements. A bank needs two
CO lines and six digital telephones (three of which
must be equipped with a PDIU-DI). It also wants to
connect a printer to a PDIU-DS.
5.42 Analysis. The bank's system hardware re-
quirements are as follows:
• Two CO line circuits for the two CO lines.
• Seven digital telephone circuits. Six for tele-
phones and one for the PDIU-DS. (The
PDIU-DIs do not require a dedicated circuit.)
5.43 Conclusion. A standard Base Key Service
Unit would be adequate in this case. The unit's
standard eight digital telephone circuits and four
CO line circuits could easily accommodate the
bank's needs.
5.50 Strata DK16 - Example 2 (Office/Ware-
house)
5.51 Customer Requirements. In addition to five
CO lines, a small office-warehouse facility needs
11 digital telephones (three of which will have
PDIU-DIs), two PDIU-DSs, a modem, a facsimile
machine, conference capability, a door phone,
one standard telephone, Music-on-hold, and an
amplifier/speaker for paging.
5.52 Analysis. The customer's requirements could
be broken down as follows:
14 digital telephone circuits
one for each of the 11 digital telephones; the
PDIU-DIs do not require dedicated circuits.
one for each of the two PDIU-DSs
one for a digital door phone/lock control unit
to support a door phone
3 standard telephone circuits
one for the modem
one for the facsimile machine
one for the standard telephone
A music source for Music-on-hold and an ampli-
fier/speaker for paging could both be connected
to the Key Service Unit RCA jacks.
A K4RCU would be needed for the Dual-tone
Multi-frequency (DTMF) tones generated by the
devices connected to the standard telephone
circuits.
A PCOU would be needed for the fifth CO line.
5.53 Conclusion. An Expansion Key Service Unit
in addition to the Base Key Service Unit would be
needed for this application. The three standard
telephone circuits could be contained on the op-
tional KSTU PCB in the Base Unit. However, a
PDKU installed in the Expansion Unit would be
required for six of the 14 digital telephone circuits.
The Expansion Unit would also be needed for the
PCOU. The optional K4RCU, along with the music
source and the page/amplifier, as noted earlier,
could be connected to the Base Unit.
