Command History
Usage Guidelines
This command sets the Connection Threshold parameter for the specified SPD in the Telephony Channel
Descriptor (TCD) messages. A dial-up attempt is considered a connection failure if an answer
connection is not made after ten rings. The CM continues to try to connect until the connection threshold
is reached. If multiple phone numbers are configured using the
cable telco-return spd phonenum
command, the CM dials each phone number until it makes a connection or exceeds the configured
threshold.
Note
This command is available only in images that support telco-return. These images have a “t” as part of
the image name.
Examples
The following example shows the connection threshold being set to 20:
router(config-if)# c
able telco-return spd 2 threshold 20
