Invalid Rng Rsp Number of times the Cisco uBR900 series received invalid ranging response
messages.
Invalid Reg Rsp Number of times the Cisco uBR900 series received invalid registration response
messages.
T1 Timeouts Number of timeouts caused by the Cisco uBR900 series not receiving a valid
upstream channel descriptor (UCD) from the CMTS within the specified time.
T2 Timeouts Number of timeouts caused by the Cisco uBR900 series not receiving a maintenance
broadcast for ranging opportunities from the CMTS within a specified time.
T3 Timeouts Number of timeouts caused by the Cisco uBR900 series not receiving a response
within a specified time from the CMTS to a RNG-REQ message during initial
maintenance.
