Amplified Conference Assignments (LED 01 W
04)-Light
LEDs 01 - 04 to identify which PEKU
ports should be connected to external amplifiers.
External Amplified Conference is provided by
customer-supplied two-way amplifiers connected
to system PEKU ports to provide amplification of
"two-line" calls. Up to four amplifiers can be
connected (two PEKU ports for each amplifier) to
amplify up to four two-line calls simultaneously
with RCTUB, RCTUBA/BB and C/D, three with
RCTUA. The amplifier is switched into the call
automatically when a two-line call is established.
Amplifiers are switched into calls starting from the
lowest PEKU ports to the highest (see Program
IO-3 System Record Sheet). Skipping PEKU ports
is allowed.
Example:
The first amplifier can be connected to
PEKU ports 017 and 018, skipping ports 009 and
010. In this case, LED 02 should be ON and LED
01 should be OFF. (See Program 10-1, LEDs 19
and 20; Program 10-2, LEDs 18 and 19; and
Program 15-5 for more information regarding Two-
line Conference.)
IMPORTANT!
A DK280 system operating with the RCTUB,
RCTUBA/RCTlJBB or RCTUC common
control unit allows up to 10 simultaneous Two-
line Conference connections (four with the
RCTUA). The amplifiers are switched in
automatically starting with the first connection.
Calls made when there are no amplifiers
available will not be amplified.
Note:
The external amplifiers will also amplify two-
line DISA, Call Forward External, DNIS
externally routed calls, DID, and tie line trunk
to trunk calls.
Program 12-System Assignments - Basic Timing
(Initialized data for Program 12: Code 3 = 1, Code 4 =
2, Code 5 = 0, and Code 9 = 4.)
n Pause Timing, Code 3-Short and long pauses
may be programmed in Speed Dial numbers by
station users. The short pause length can be set
system wide for either 1.5 or 3 seconds with this
program. The long pause is always 10 seconds.
Note:
This program applies to Speed Dial numbers
used for both voice and data calls. Data call
pause length is determined by the program.
n
Flash Timing, Code
4-When on a CO line, a
station user can press the Flash button and the
line will open (flash) for a period of either 2
seconds, 0.2 seconds, or 0.5 seconds depending
on this assignment. (A flash can also be activated
by dial code Cnf/Trn # 4 5). In general, this
choice reflects whether to disconnect and regain
dial tone (two seconds), or to use PBX or Centrex
features which require a flash signal (0.5
seconds). This flash timing also applies to flashes
inserted when dialing via data interface units
(DIUs).
Note:
The 0.2 seconds option is not normally used
in the United States.
4 Pause After Flash, Code
5-Some COs or
Centrex facilities require a period of time after a
flash signal before they can accept dialing signals.
A selection of pause timing is available to
automatically delay any dialing signals after flash.
This timing applies to Speed Dial calls (with flash
signals between the telephone number digits) as
well as to manual dialing.

Auto Attendant, DISA, Call Forward External,
and DNIS External Network Routing
Disconnect Timer, Code
8-If any of the call
types listed above are made on loop start lines a
call could lock-up (keep busy indefinitely) if the CO
does not send a disconnect signal (CPC or AR)
when the callers hang up. This timer will prevent
loop start lines from locking up by disconnecting
the call automatically when the timer expires, 4,
10, or 20 minutes from the start of the call. Callers
will hear a warning tone and can reset the timer
repeatedly by dialing "0". This disconnect feature
is only needed for loop start lines.
H
WCS Seize Time, Code
g-One channel of the
RRCS Dual-tone Multi-frequency (DTMF)
receiver/decoder is seized when it is needed for
the decoding process, such as with a standard
telephone with a DTMF dialpad. When placing
outgoing calls with DTMF standard telephones,
the talk path to the outside party is not "cut-
through" until the RRCS circuit is released. The
