5.30. Satellite Paths Limiting Previous topic Parent topic Child topic Next topic

With this feature, it is possible to limit the number of satellite paths involved in a connection. The feature was introduced in order to ensure speech quality through adherence to the runtime requirements. The SATELLITE COUNTER introduced for this feature counts the number of satellite paths passed through. In those nodes in which a trunk group to a satellite is to be seized (in the o/g direction) a check is carried out to establish whether the threshold value has already been reached for this connection. The currently active counter, referred to in the connection setup message, is compared with the threshold value for the o/g trunk group. The connection is cleared down and an advisory issued if the counter reading, incremented by one, is higher than the threshold value; in all other cases the incremented counter reading is indicated in the message.
INFO:
Unlike the TRANSIT COUNTER check, the SATELLITE COUNTER check is performed on the o/g side before the path is seized.

The following AMOs affect this feature:

AMO COT:
Parameter
PAR=SATV: COT with check of the number of satellite paths passed through.
   
PAR=/SATV (default): no SATELLITE COUNTER check.
AMO PRODE:
Parameter
PVCD: Copying the country-specific protocol tables to the database. The CORNV33 protocol must be supported.
AMO TDCSU:
Parameter
PROTVAR: Assigning the CORNV33 protocol to the digital tie trunk circuit.
Parameter
COTNO: Assigning the COT with SATELLITE COUNTER check to the digital tie trunk circuit. The COT must first be defined by means of AMO COT (with Parameter SATCOUNT COTPAR=SATV). Not until then is the parameter SATCOUNT analyzed.
Parameter
SATCOUNT=NONE: No satellite connection permitted.
   
SATCOUNT=NONE: One satellite connection permitted
   
SATCOUNT=TWO: Two satellite connections permitted
   
SATCOUNT=MANY (default): Any number of satellite connections permitted.

Configuration of satellite path limitation

The normal configuration is no limitation. The restriction can be activated with the aid of the following commands:
  • Define COT for SATELLITE COUNTER check
    AD-COT:COTNO=10,PAR=SATC; 
    
  • Load country-specific protocol for Germany
    COPY-PRODE:TYPE=PVCD,PVCDNR=1; 
    
  • Parameterize digital circuit so that two satellite paths are admissible
    AD-TDCSU:OPT=NEW,....,COTNO=10,PROTVAR=CORNV33,SATCOUNT=TWO;
