The testing circuit
7140 can establish the following test connection:
- via tie line and PEN of station 7241
- via tie line and station number of station 7241
After the connection to the second PBX is established, a continuous
tone is injected. Then the remaining digits can be entered.
This selection can be made via several nodes.
- Configure Wabe:
ADD-WABE:CD=**88,DAR=CTLS;
- Set the authorization:
ADD-COSSU:NEWCOX=xx,AVCE=CTLS;
- Set COT for the trunks:
ADD-COT:COTNEW=xx,PAR=CTLS,INFO="Selective line seizure";
- Set "TESTLN" in WABE:
If a test station is to be tested in the CTLS test, the DAR TESTLN with the CPS 10&11 must be set for this station. For the outgoing trunk the COT CTLS must also be set.
ADD-WABE:CD=**89,CPS=10&11,DAR=TESTLN;
- Set the test tone length
With CTLS the test tone injection is timer controlled. The duration of the test tone can be set using the CP timer CTLS1 (AMO CTIME, TYPESWU=CP).
CHA-CTIME:TYPESWU=CP2,CTLS1=20; /*inject test tone for 20 seconds
