To monitor the SS7 network, use the SS7 Monitor. You can do this in either Operator or Administrator mode.

The Monitor Entities and Single Entity Statistics menu items let you monitor and get statistics on the SS7 network and about hardware status. These menus can be accessed in Operator (non-privileged) mode, as well as in Administrator mode. Refer the SS7 Monitor on-line help for details on the information provided.

“SS7 Monitor Interface” for information on syntax and navigation.

Changing the SS7 Monitor Mode

To switch between the available modes, edit the file /etc/opt/OC/management/mgtProcessList.conf to comment out the lines that you do not require:

# To start Administrator SS7 Monitor(s)
$BINPATH/ss7AdmMon -C $CLASSNAME_1 -typeName $TYPENAME_1
# To start Operator SS7 Monitor(s)
#$BINPATH/ss7OpeMon -C $CLASSNAME_1 -typeName $TYPENAME_1

Available Network Entities

Using the Operator’s interface, you can monitor the following:

  • Hardware State

  • MTP

  • SCCP

  • TCAP

  • GDI

Monitoring MTP

If you choose MTP from the main menu, you can choose to monitor one of the following:

  • MTP

  • Destinations / Routes

  • Links / Linksets

Monitoring Overall MTP Layer Traffic

From the Monitor MTP window you can activate, deactivate, and monitor the overall traffic of the MTP layer of the SS7 stack.

Monitoring Destinations/Routes

From the Monitoring Destinations/Routes window you can activate, deactivate, and monitor the status of destinations, or individual routes to one destination. The window shows the states as defined in the ITU-T/ANSI recommendations.

NOTE: As soon as one route leading to a destination is congested, the destination is declared congested even if there are other uncongested routes leading to that destination.
Search

Use the (S)earch function (type S) to find a particular destination point code.

Test

Use the (T)est function (type T) to test the route in the TTC standard. The local host sends a SRT and expects the return of an SRA. The return notification will display, for example:

*** Routing test successful on route DPC, RPC ***

or

***Error: Routing test failed on route DPC, RPC ***

This testing function is not available for the ITU-T nor ANSI standards. If you try to test these standards, you will see an error message.

You cannot access the route while it is being tested.

Monitoring Links/Linksets

From the Monitoring Links/Linksets window you can activate, deactivate, inhibit, uninhibit and monitor the status of links to adjacent DPCs.

You can also monitor overall traffic on the linksets.

Abbreviations used in this window are as follows:

  • in the column AIOC, A = Active, I = Inhibit, O = Out of Service, C = Congested, ---- = inactive

  • Rx %Use = percentage link utilization rate for reception

  • Tx %Use = percentage link utilization rate for transmission

Link Inhibit

The link inhibit command works for ANSI and ITU-T stacks, but is not in the TTC standard. If you use TTC, you will see an error (ILLEGAL_OA_OPERATION) if you try to inhibit a link.

Search

Use the (S)earch function (type S) to find a particular destination point code.

Linkset/Link Activation Behavior

When the Stack Starts

The activation behavior of Link/Linkset is automatic if the links have been configured, that is your links become ACTIVE. If a Signaling Unit has a status of ONLINE, the link(s) pass from INACTIVE, to OUT_OF_SERVICE to ACTIVE.

If the Signaling Unit has a status other than ONLINE or STANDBY, the Signaling Unit is reloaded until it has an ONLINE or STANDBY state, and then the links will pass through the states as described above.

When the Stacks Switchover

If the Signaling Unit must pass from STANDBY to ACTIVE in the case of a HP OC SS7 host switchover, the links are not impacted and remain ACTIVE.

NOTE: When a destination is out-of-service, because of a network problem (remote destination not responding to alignment procedure, for example) you cannot inhibit all the links of a linkset. You must first deactivate the failed destination.
Starting Up After a Switchover (Active/Standby Mode Only)

If a switchover occurs when the MTP is not active, it means that synchronization failed. In this case, stop the synchronization before you re-start. You should:

  1. Stop the synchronization.

  2. Activate MTP.

  3. Re-start synchronization.

Configuring GDI

The GDI configuration screen allows you to configure the remote hosts which are authorized to connect to a particular HP OpenCall SS7 stack using GDI. Connection attempts from a non-authorized hosts are refused.

A GDI remote host is identified by its DGPC (Distant GDI Point Code) and by one or two IP addresses. The DGPC is a logical local identifier. The remote IP address and the corresponding LAN must be configured on the remote client.

NOTE: To connect to a the TCAP application, you must use SSN 256. SSN 256 is reserved in the SS7 stack for GDI. You cannot manually change this using the SCCP configuration menu.

Single Entity Statistics

The following options are available:

  • MTP

  • Linkset

  • Link

  • SCCP

  • TCAP

The statistical data for the selected entity is updated every few seconds.

MTP

From this window you can see the MTP statistics for the local point code.

Linkset

Enter the identifier of the linkset that you want to monitor.

Link

Select a link that you want to monitor.

SCCP

Enter S, then enter the entity (select from 1 to 5) and parameters that you want to monitor:

Example:

(2) Local User [ 2 <ssn> ]: in this case, enter 2 then the ssn.

TCAP

From this window you can see the TCAP statistics for the local point code.

GDI

From this window you can see the GDI statistics for the local point code.
