PGW configuration assistance

dear all

i have a problem in configuring PGW2200

i configured the SS7 routes and c7links and i found the status of the links as following:
pgw-b mml> rtrv-c7lnk:c7lnk-sis-0:
MGC-02 – Media Gateway Controller 2008-10-23 11:06:20.850 EDT
M RTRV
“c7lnk-sis-0:ls-sis-egypt-0,LID=0:IS”
/* c7link sis-0 */

but the ss7path is AOOS as following :
“ss7path-sis-0:DPC=001.000.001,DNW=2:OPC=001.002.006:AOOS”

if any one can help me in solving this problem
