19
Program Option [39] as “01” to enable the line fault report;
program “00” to disable the transmission of the line fault
condition to computer and printer.
[DEFAULT 01]
Option [3A]: Programmable Output
The DRL2A provides one programmable output at the terminal
TxPG1 of the DML2A backplane board, for the left hand
Line Card, and one programmable output at the terminal
TxPG2 for the right hand Line Card.
Program Option [3A] with one of the following:
00
Programmable output follows the Error Message
LED
01
Programmable output will switch to ground for
100mS in Two-way Audio Condition
NOTE:
This option will be over-written by the Video
DOWNLOOK option selection.
[DEFAULT 00]
Option [3B]: FBI RS232
To enable the computer FBI superfast protocol, program
the option [3B] as "01". Please see page 42 for details.
[DEFAULT 00]
Option [3C]: Filter Option
The Line Card will process incoming signals through a filter
circuit if this option is selected. If this option is not selected,
the Line Card will process incoming signals through a software
filter. Program Option [3C] as “01” to enable this feature, or
as “00” to disable it.
[DEFAULT 00]
Option [3D]: Reserved for future use
Option [3E]: Mute Buzzer
Operation of the Line Card’s buzzer may be programmed
as follows:
00
Buzzer sounds for Line Fault, CPM2 Error, or if
an Alarm occurs during a CPM2 error
01
Buzzer does not sound for any events
02
Buzzer sounds for Audio, Line Fault, CPM2 Error,
or if an Alarm occurs during a CPM2 error
03
Buzzer sounds for all status change conditions
[DEFAULT 00]
Option [3F]: Last Message On
When Option [3F] is enabled, the last alarm message will
be retained on the Line Card display screen until a new
signal is received. Program Option [3F] as “01” to enable
this feature, or as “00” to disable it. If Option [3F] is disabled,
the stand-by message described in Section 1.4 will be
displayed when communication of an event is completed.
[DEFAULT 00]
Option [40]: Hook Flash
The hook flash feature is used for two-way audio in a PBX
system. The line card can hook-flash the line for 100ms-
900ms programmable to put the line on hold and then back
on line for 3 seconds and hang up. Program option [40] to
"01" for 100 ms, "02" for 200 ms, etc. "00" will disable the
option.
[DEFAULT 00]
Options [41] through [46]: Handshake Selection
The DRL2A is a multi-format receiver capable of sending
several handshakes to a dialer. Often it is important which
handshake is sent first. Program Options [41] through [46]
according to your applications. If all six Options are
programmed as “00”, 2300Hz handshake will be sent.
Handshake Options
00
No handshake
01
Dual tone handshake
02
2300Hz handshake
03
1400Hz handshake
04
SIA FSK handshake
08
Modem II handshake
10
Modem IIE and ITI handshake
13
Single Dual tone handshake
(Refer to Appendix D for Corresponding Formats)
Option [47]: Handshake and Kissoff Duration
Some control panels have difficulty in understanding the
receiver’s handshake and/or kissoff tones on noisy phone
lines. Option [47] provides a possible solution for this problem
by providing longer constant tones. Program one of the
following:
00
1.0 second tone
01
1.5 second tone
02
2.0 second tone
03
800 ms tone
Note that this option affects only handshakes 02 and 03.
[DEFAULT 00]
Option [48]: Interval Delay Between Handshakes
The DRL2A Line Card will usually wait for signals from the
control panels for 4 seconds before sending the next
handshake, if there is no signals received. In certain
applications, control panels can not wait long enough to
get their own handshake especially if the handshake is
programmed as the third or fourth handshake.
Program Option [48] with one of the following:
00
4 second interval
01
1 second interval
02
2 second interval
03
3 second interval
[DEFAULT 00]
Option [49]: 2-Way Audio (Handset) Activation Time
Option [49] determines how long, in minutes, the 2-Way
Audio function will be active once it is initiated. At the end
of this time, the Line Card will hang up the line.
Program a value from “01” to “99” for 1 to 99 minutes.
Three (3) minutes is the recommended length of time for
the 2-Way Audio Activation time.
To disable the 2-Way Audio feature, program Option [49]
as “00”.
NOTE:
SIA, Contact ID FBI Super Speed and Modem II, will
identify to the DRL2A when it should switch into Two-Way
Audio. Therefore overwriting option 4A, 4B and 4C, but will
still follow the time programmed at option 49.
[DEFAULT 00]
Option [4A]: Account Codes to Activate 2-Way Audio
Option [4A] determines which Account Codes will be able
to activate the 2-Way Audio feature. Program the first digits
of the desired Account Codes in Option [4A]. For example,
to allow all account codes between 1000 and 2FFF to activate
the 2-Way Audio function, program Option [4A] as “12”. To
allow all account codes between 3000 and 6FFF to activate
the 2-Way Audio function, program Option [4A] as “36”.
