Note You might need to enable this command on several different combinations of ports to
determine which one is not functioning properly. A pair of operable ports successfully
connects and completes transmitting data in both directions. An operable port and an
inoperable port do not successfully connect with each other.
A sample back-to-back test might look like the following:
Router# test port modem back-to-back 2/10 3/20
Repetitions (of 10-byte packets) [1]:

in back-to-back test:CONNECT33600/V34/LAP

Tips You may reboot the port that has problems using the clear spe EXEC command.
• Enter the spe recovery {port-action {disable | recover | none} | port-threshold num-failures}
command to perform automatic recovery (removal from service and reloading of SPE firmware) of
ports on an SPE at any available time.
An SPE port failing to connect for a certain number of consecutive times indicates that a problem
exists in a specific part or the whole of SPE firmware. Such SPEs have to be recovered by
downloading firmware. Any port failing to connect num-failures times is moved to a state based on
the port-action value, where you can choose to disable (mark the port as Bad) or recover the port
when the SPE is in the idle state and has no active calls. The default for num-failures is 30
consecutive call failures.
Tips You may also schedule recovery using the spe download maintenance command.
• Enter the spe download maintenance time hh:mm | stop-time hh:mm | max-spes number | window
time-period | expired-window {drop-call | reschedule} command to perform a scheduled recovery
of SPEs.
The download maintenance activity starts at the set start time and steps through all the SPEs that
need recovery and the SPEs that need a firmware upgrade and starts maintenance on the maximum
number of set SPEs for maintenance. The system waits for the window delay time for all the ports
on the SPE to become inactive before moving the SPE to the Idle state. Immediately after the SPE
moves to Idle state, the system starts to download firmware. If the ports are still in use by the end of
window delay time, depending upon the expired-window setting, connections on the SPE ports are
shutdown and the firmware is downloaded by choosing the drop-call option, or the firmware
download is rescheduled to the next download maintenance time by choosing the reschedule option.
This process continues until the number of SPEs under maintenance is below max-spes, or until
stop-time (if set), or until all SPEs marked for recovery or upgrade have had their firmware
reloaded.
