POLAND - TEST CALL
Definition / Use
This feature is used for test call handling by the Polish
PSTN to check the speech (B-) channels of external
lines.
The primary usage is in conjunction with CAS trunks
but it is also possible to be used for other types of
trunks.
Operation
The test call is initiated by the PSTN by direct dialling
in, either decadic or MFC. The dialled digits are related
to a specific ‘extension number’ which in turn starts the
test call sequence.
The test sequence is predefined:
Ring tone is sent during predefined time
(approx. 8 sec.) and then speech connection is
established to PSTN.
Test tone with predefined frequency ( 800 Hz )
and cadencies is sent to the PSTN (3 cycles of
2,5 sec. on and 2,5 sec. off at a level of -6 dBm0).
The connection is released by ASB 150 02.
Capacity / Limitations
This test can be used in all automatic incoming call
cases. Used register signalling can be e.g. decadic,
DTMF and MFC. Related trunks can be analogue,
CAS and ISDN.
One 1 - 4 digit test call number is available (see
comand 5414).
Programming
The following commands are only accessable via
RASC:
2649
Test tone
The test tone is used for external line testing purposes
to check the condition of speech (B-) channels.
For Polish test call handling following values have to be
entered:
2601
Tone fragment definition
This command defines the tone fragments for the test
tone for command 2649. The predefined default values
for the Test Call Poland are: 800 Hz and -6dBm0.
5414
Create test call numbers
This test call number which is expected to be received
from the PSTN Poland is created by this command in
line "Test call number for Poland".
5514
Delete test call numbers
The test call number is deleted by this command in line
"Test call number for Poland".
5622
Alter test call numbers
The test call number is altered by this command in line
"Test call number for Poland".
Equipment
A BTU-D card with CAS prom set is necessary to
perform the test.
