Resolving SS7 Network Related Problems
Setting the Service State of a C7/SS7 Link or Linkset
To change the service state of an SS7 link, log in to the active Cisco PGW 2200 Softswitch, start an MML
session, and enter the set-c7lnk:c7link_name:serv_state command.
Where:
• c7link_name—MML name of the SS7 link you want to modify.
• serv_state—Service state to set. Valid values for SS7 links are IS, OOS, FOOS, INH, and UNH.
Note To set the last link in a linkset out of service, you must enter the FOOS service state in the
command.
For example, to set the service state of the SS7 link (c7link1) to IS, enter the set-c7lnk:c7link1:IS
command.
Verify if the selected SS7 link is in the proper service state by performing the procedure in the Retrieving
Service State of C7/SS7 Links or Linksets, page 3-45.
Note To modify the service state of the backhaul link for the Cisco ITP-L, set the state of all link types that
are associated with that Cisco ITP-L. The possible link types are S77 links (c7lnk), D-channels, (dchan),
and IP links (iplnk).
Setting the Service State of an IP Link
To change the service state of an IP link, login to the active Cisco PGW 2200 Softswitch, start an MML
session, and enter the set-iplnk:iplink_name:serv_state[::confirm] command.
Where:
• iplink_name—MML name of the IP link you want to modify.
• serv_state—Service state that you want to set. Valid values for IP links are IS, OOS, and FOOS.
• confirm—This parameter is required when you are setting the service state of an MGCP link. Other
types of IP links do not require this parameter.
For example, to set the service state of the IP link (iplink1) to IS, enter the set-iplnk:iplink1:IS
command.
For example, enter the set-iplnk:mgcplnk1:IS:confirm command to set the service state of an MGCP
link called mgcplnk1 to IS.
Verify that the selected IP link is in the proper service state by performing the procedure in the
“Retrieving the Service State for IP Links” section on page 3-46.
Note To modify the service state of the backhaul link for the Cisco ITP-L, set the state of all link types that
are associated with that Cisco ITP-L. The possible link types are S77 links (c7lnk), D-channels (dchan),
and IP links (iplnk).
