Each communication port served by the Connection Oriented Router (COR) and "RUNNING" is provided with a maximum number of sessions equal to the sum of the PVC and SVC channels configured in its parameters.
Session numbering always starts from 1 and it is contiguous.
In SVC sessions, the index (SES:) is not related to the number of the logical channel in use (LGCN), while in PVC ones they coincide (SES:=LGCN).
Commands for displaying the sessions status are described in the section COR connections of chapter Commands relating to the Connection Oriented Router. The available commands are:
C CThe command D C shows the current status of sessions. Here is an example of displaying all the ports status, shown values are examples:
[14:40:11] ABILIS_CPX: D C PO:A PO:0 SES:1 CONN FROM PO:905 SES:4 CG: PR:0 PO:0 SES:2 UP CLR:00,00 PO:0 SES:3 CONN FROM PO:905 SES:1 CG: PR:0 PO:21 SES:1 DOWN CLR:F0,B0 PO:301 SES:1 UP CLR:F0,B0 PO:301 SES:2 UP CLR:F0,B0 PO:301 SES:3 UP CLR:F0,B0 PO:301 SES:4 UP CLR:F0,B0 PO:301 SES:5 UP CLR:F0,B0 PO:328 NO SESSIONS AVAILABLE PO:900 NO SESSIONS AVAILABLE PO:905 SES:1 CONN TO PO:0 SES:3 CD:00 PR:0 PO:905 SES:2 UP CLR:F0,D0 PO:905 SES:3 UP CLR:00,00 PO:905 SES:4 CONN TO PO:0 SES:1 CD:00 PR:0 PO:905 SES:5 UP CLR:00,00 PO:905 SES:6 UP CLR:00,00
As the previous example shows, for active connections the following information set is displayed:
For not active connections the following information set is displayed:
The command D CE shows the current status of sessions, it also displays the call data for active and not active sessions. Here is an example of the information displayed after executing this command. Shown values are examples.

For active connections the following information set is displayed:
For not active connections values related to the last connection or last connection try are displayed:
It is important to underline that these commands work only on "RUNNING" ports, which have also to be served by the COR. To have a list of all the running ports, use the command D RUN.
If a given port is "RUNNING" but neither SVC or PVC sessions have been configured, both the commands will show the message "NO SESSION AVAILABLE" in correspondence of that port.
The following example shows extended information about a single port, the other example demonstrate how to clear a particular connection:
