transmitted to the CPM directly with the help of a
special protocol. If turned off, one fault call or fault
data message per call will be transmitted to the CPM.
Debug Mode
(OFF)
The Debug Mode feature can be turned of by
pressing the < key, the Line Card will receive the
calls in silence. It can be turned on with the > key,
then all the communication going on the phone line
will be heard. The default setting is off.
LCD Contrast
The contrast of the Line Card LCD can be set here.
The lower values will result lighter display, the higher
values on the opposite, darker.
LCD Contrast
008 (00-15)
The contrast value can be decreased with the < key
and increased with the > key. The contrast can be set
from 0 to 15. The default setting is 8.
The Handshakes
The number and order of handshakes that a Line
Card will give on a call are programmable. The
maximum number of handshakes is 8. Each
handshake can be set independently at the Format
Options, HSK Sequence section
HSK Sequence
< Handshake 01 >
Each handshake can be set from 0-4, the numbers
have the following meaning:
00
No handshake, terminator
01
Dual tone handshake (1400/2300 Hz)
02
2300Hz handshake
03
1400Hz handshake
04
SIA FSK Handshake (2225 Hz)
The last handshake in the sequence have to be 00,
this acts as a terminator of the handshake sequence.
The handshake numbers can be increased with the <
button and decreased with the > button. The default
handshake sequence is 1-2-3-4-0-0-0-0.
The duration of the handshakes defines how long
should the Line Card emit the 1400 Hz and 2300 Hz
handshakes. This option can be set at the Format
Options, HSK Duration section of the menu:
HSK Duration
009 x 100 ms
The time can be adjusted by 100 milliseconds from 5
to 80. The default value is 9 which means 9 x 100 ms
= 0.9 seconds.
The interval between the handshakes gives the time
the Line Card will wait for an answer after issuing a
handshake. After the handshake interval time has
expired the Line Card will give the next handshake or
terminate the call. The handshake interval value can
be set at the Format Options, HSK Interval section:
HSK Interval
040 x 100 ms
The interval can be adjusted by 100 milliseconds
from 4 to 64. The default value is 40 which means 40
x 100 ms = 4 seconds.
The billing delay is the time the Line Card will wait
after answering the call to give the first handshake.
The time can be set at the Format Options, Billing
Delay section of the menu:
Billing Delay
020 x 100 ms
The delay can be adjusted by 100 milliseconds from
5 to 40; the display is hexadecimal. The default value
is 20 which means 20 x 100 ms = 2 seconds.
The length of the SIA handshake can be set
independently of other handshakes. This option can
be set at the Format Options, SIA HSK Length
section of the menu:
SIA HSK Length
009 x 100 ms
The time can be adjusted by 100 milliseconds from 3
to 20. The default value is 9 which means 9 x 100 ms
= 0.9 seconds.
Communication Options
The communication programming options include
communication
timeout
and
format
selection
programming. The communication timeout defines
the time the Line Card will wait for a communication
event, after it has received an event. This parameter
can be set at the Format Options, Comm. Timeout
section:
Comm. Timeout
50 x 100 ms
The timeout can be adjusted by 100 milliseconds
from 10 to 160. The default value is 50 which means
50 x 100 ms = 5 seconds.
