Parameter: CRC Size
Path: HSSI Connector > Edit Line > Edit HSSI Parameters
Default: 32 bit
Options: 16 bit
| 32 bit
Function: Specifies an error detection scheme. You can choose either 16-bit (standard
ITU-T) or 32-bit (extended) to detect errors in the packet.
Instructions: Set this parameter to either 16-bit or 32-bit, making certain that the remote end
of the HSSI connection is configured for the same value.
MIB Object ID: 1.3.6.1.4.1.18.3.4.7.15
Parameter: Carrier Loss Debounce
Path: HSSI Connector > Edit Line > Edit HSSI Parameters
Default: 0
Options: 0 to 2147483647 seconds
Function: Determines how many seconds the line driver waits after losing the carrier
signal before transitioning to the Carrier Lost state. If the carrier signal returns
prior to reaching this threshold, the driver never enters Carrier Lost.
Instructions: For most lines, you want the driver to immediately transition to Carrier Lost
state upon detecting carrier loss. For a problem line, however, you can enter a
number of seconds for the router to sense carrier loss before entering Carrier
Lost state.
MIB Object ID: 1.3.6.1.4.1.18.3.4.7.
