Status String Meaning
Inactive The interface is not yet active.
Waiting for rate negotiation The interface is in the process of sensing the data rate
configured for the IDSL line at the central office. This status
applies only to an interface set to idsl-cmn mode, in which the
router can sense the data rate automatically.
Backup recovery in progress The interface is in the process of recovering back to the
primary interface from a backup interface after a failure.
Connected at xxx Kbps The interface is connected to the DSLAM or other end device at
the specified data rate. (xxx will be one of 64, 128, or 144.)
Status String Meaning
Inactive The interface is not yet active.
Active The interface is active, and this is an interface that does not
require SPIDs.
Active, n of m SPIDs
registered
The interface is active, and this is an interface that requires
SPIDs. n indicates the number of SPIDs that have been
successfully registered so far, and m indicates the total
number of SPIDs to be registered. If n is less than m, the
device is still in the process of registering some of the SPIDs.
