MTP3 Userpart Configuration

• MTP3 user part unique ID is used to configure identical MTP3 userparts in each MTP3 module and to connect ISUP networks.

---

• The Connection mode parameter specifies the different modes of connection for an MTP3 userpart. The following values are allowed:

Connection mode	Description
SCCP	MPT3 userpart is used in conjunction with an above local SCCP layer and cannot be controlled by the host application
SCCP with alarms	MPT3 userpart is used in conjunction with an above local SCCP layer and cannot be controlled by the host application but the host application will receive ALARM notifications
ISUP	MTP3 userpart is used in conjunction with an above local ISUP layer and cannot be controlled by the host application
ISUP with alarms	MPT3 userpart is used in conjunction with an above local ISUP layer and cannot be controlled by the host application but the host application will receive ALARM notifications
Host SCCP	MTP3 userpart is used as a standalone and communicates with remote SCCP layer (host application)
Host TUP 5	MTP3 userpart is used as a standalone and communicates with remote TUP layer (host application)
Host ISUP	MTP3 userpart is used as a standalone and communicates with remote ISUP layer (host application)

• The Sub-service field specifies the type of network. If validation is activated in the general MTP3 configuration, all userpart messages will be compared to this sub-service field type. All non-matching messages will be discarded. The following values are allowed:

Sub-service field	Description
International	Messages sent by the layer will concern international traffic
National	Messages sent by the layer will concern national traffic
Reserved	Reserved for national use

NOTE: For all national networks (including TTC and NTT), the 'Sub-service' field is configured with 'National'. For international networks, the 'Sub-service' field is configured with 'International'.

NOTE: For international networks you must have the same values for Prior Message Queue Length 1 to Prior Message Queue Length 1 in a MTP3 Link Configuration.

---

• The Link type field specifies the MTP3 protocol variant required to provide service to the userpart connected through this upper Service Access Point (SAP). The following values are allowed:

Link type	Description
ANSI	Used for ANSI88 and ANSI92
ITU	Used for ITU88, ITU92, ITU97, Q767, SINGAPORE and ETSI
CHINA	Used for CHINA
ANSI96	Used for ANSI96 and TELCORDIA
TTC	Link type not available yet
NTT	Link type not available yet

• The DPC length field specifies the length of the DPC for messages communicated through this SAP. For allowable values, see MTP2:Destination Point Code.

• The Switch ID parameter specifies a value to regroup linksets and user parts together. Allowable values are from 10 to 255.
