Description of parameters
General explanation of the configuration parameters:
- The Network identifier parameter specifies the ID of the network
- The Protocol variant parameter specifies the SCCP protocol variant required to provide service to the userpart connected through this upper Service Access Point (SAP). Allowable values are:
Protocol variant | Description |
---|---|
ANSI | Used for ANSI |
ITU | Used for ITU |
CHINA | Used for China |
- The Self point code parameter contains the point code (address) of the local SS7 node to which the SCCP network is bounded to. Proper point code length is described in MTP2:Destination Point Code.
- The Sub-service field specifies the type of network. Allowable values are listed in SSF values table in MTP3:Userpart Configuration.
- The Default hop count parameter specifies the default hop count value. Allowable values are between 1 and 15.
- The Network bit parameter specifies the network indicator bit. Used in the SCCP address (example when sending management messages). Allowable values are:
Network Indicator Bit | Description |
---|---|
International | International indication |
National | National indication |
- The Use mapping of SIO priority importance flag parameter. Flag indicating presence of SIO priority to importance mapping. SIO priority to importance mapping should be configured only if SIO priority is carrying message importance as a national option. Allowable values: 'True' or 'False'.
- The Array of SIO priority importance parameter specifies the mapping of SIO priority to importance of message value.
- The Network timers configuration parameters are defined as follows:
Connection mode | Description |
---|---|
SST Timer | Default subsystem status test timer. Time between sending SST messages to unavailable remote subsystem. This is the same as timer T(stat.info) in T1.112.4 and Q.714. Typical value is 30,000 milliseconds (30 seconds) for ANSI and 5000 milliseconds (5 seconds) to 1,200,000 milliseconds (20 minutes) for ITU. |
SRTTimer | Default subsystem routing test timer. Time between sending SRT messages to remote subsystem (ANSI and TELCORDIA). This is the same as timer T(rtg.stat.info) in T1.112.4. Typical value is 30,000 milliseconds (30 seconds). |
Ignore SST Timer | Default ignore SST timer. Time to ignore SST messages after receiving a subsystem Out-of-Service Grant (SOG) message. This is the same as timer T(ignore.SST) in T1.112.4 and Q.714. Typical value is 30000 milliseconds (30 seconds) for ANSI and selected by management for ITU. |
CRDTimer | Default coordinated state change timer. Time to wait for subsystem SOG message. This is the same as timer T(coord.chg) in T1.112.4 and Q.714. Typical value is 30,000 milliseconds (30 seconds) for ANSI and 60,000 milliseconds (1 minute) to 120000 milliseconds (2 minutes) for ITU. |
AsmbTimer | Default extended unit data reassembly timer. This is the same as timer T(reassembly) in Q.714. Typical value is 10,000 milliseconds (10 seconds) to 20,000 milliseconds (20 seconds). |
Attack Timer | Default attack timer (ITU96). This is the same as timer Ta in Q.714. Typical value is 100 milliseconds to 600 milliseconds. |
Decay Timer | Default decay timer (ITU96). This is the same as timer Td in Q.714. Typical value is 1000 milliseconds (1 second) to 10,000 milliseconds (10 seconds). |
Congestion Timer | Default SCCP congestion timer (ITU96). This is the same as timer Tcon in Q.714. Typical value is 1000 milliseconds (1 second) to 10,000 milliseconds (10 seconds). |
