The Number Portability Gateway (NPGW) application is a message gateway and as such statistics are required to provide throughput numbers. The DSC Platforms provide NPGW data measurements as described in the following table.
Statistics Per System
All statistics are calculated over all routing CPUs, not on a per CPU/slot basis unless stated otherwise.
The following figure shows an example for these measurements.

The instance represents the application object that generates the data measurements. The NPGW instance value is formatted as follows:
- NPGW
Statistic | Description |
|---|---|
| MTP3 Incoming Messages | Number of MSUs received from the SS7/IP network at the NP Gateway from MTP3. |
| MTP3 Incoming Octets | Number of octets received from the SS7/IP network at the NP Gateway from MTP3. |
| PSX NP T-ISUP Outgoing Queries | Number of NP Triggerless ISUP queries sent to the PSX. |
| PSX NP T-ISUP Incoming Responses | Number of NP Triggerless ISUP responses received from the PSX. |
| PSX NP T-ISUP IAMs Not Ported | Number of IAMs which are not ported as per the PSX responses. |
| PSX NP T-ISUP IAMs Ported Prefix | Number of IAMs which are ported via the IAM prefix option as per the PSX responses. |
| PSX NP T-ISUP IAMs Ported REL | Number of IAMs which are ported via the REL return option as per the PSX responses. |
| PSX NP T-ISUP Unassociated Responses | Number of NP Triggerless ISUP responses received from the PSX that cannot be matched to pending queries. Likely due to expiry. |
| PSX NP T-ISUP Queries Timeout | Number of NP queries which did not receive a response in the configurable timer interval. |
| PSX NP T-ISUP Invalid Intercepts | Number of invalid intercepted messages for NP Triggerless ISUP. |
| PSX NP T-ISUP NP Errors | Number of IAMs which could not complete the PSX NP database dip (excluding timeouts). This includes PSX down, PSX queue full, and NP response digit processing errors such as out of bounds. |
| PSX NP T-ISUP Average Response Time | Average response time for a NP Triggerless ISUP query to the PSX. |
| PSX NP T-ISUP Average Response Sample Size | Sample size of the average response time for a NP Triggerless ISUP query to the PSX. |
