Component States
Signaling destination problems can result from any of the following:
• SS7 traffic restart handling
• SS7 STP problems
• Configuration problems
• Software problems
• Bearer Channels
Bearer channels are at the core of the solution. The goal is to ensure that a bearer channel successfully
communicates between two endpoints. The state of the bearer channels is often a good indicator as to
the health of the overall system. In the SS7 network, CICs identify each bearer channel in the network.
The state of each channel is maintained by the EMS.
Destination Point Code Status
This example describes the status command for destination point codes (DPCs).
CLI> status dpc id=dpc1;
Reply : Success:
DPC ID -> dpc1
OPER STATE -> DPC IN SERVICE
RESULT -> ADM configure result in success
REASON -> ADM executed successful
The possible operational states returned by the status dpc command are as follows:
• DPC IN SERVICE—the connection to the DPC is up and the DPC is in service.
• DPC OUT OF SERVICE—the connection to the DPC is down and/or the DPC is out of service.
Note The DPC-ID is not the destination point code (DPC). You must check the DPC-ID entry in the
Destination Point Code table to determine the actual DPC value.
Aggregation Status
Aggregation routers are used in the Cisco BLISS for Cable solution as cable modem termination systems
(CMTSs).
Use the following command to check the status of an aggregation router (CMTS):
CLI> status aggr id=CMTS1
Reply : Success:
AGGR ID -> CMTS1
OPER STATE -> AGGR IN SERVICE
RESULT -> ADM configure result in success
REASON -> ADM executed successful
The possible operational states returned by the status aggr command are as follows:
• AGGR IN SERVICE—the connection to the CMTS is up and the CMTS is in service.
• AGGR OUT OF SERVICE—the connection to the CMTS is down or the CMTS is out of service.
