MS48IP Programming Guide
79
CRL Time Filter:
If there is no metering pulse or polarity reversal facilities on lines, then this program
can be used to calculate the outgoing call duration as appropriate as possible.
8 7 7 7 P
Parameters
P
:
10 …90
CRL Filter Time in seconds.
Default Value
P=30
Notes
1. The minimum value of the parameter P is 10 for export systems.
2. This program is used to record calls as the duration specified with “P” elapsed
without any relevant tone (ring back, busy, overflow, etc.) is received through
the line.
3. For the extensions to which fax or modem is connected, the tone reception
routines used by this program may decrease the communication speed.
Therefore, for such extensions the intrusion authority level is set to “6” and thus
the CRL Time Filter is not applied to these extensions and thus the
communication speed is high enough.
