COMSPHERE DualFlow Data Service Units
Auto Bckup:Disab
Next Enab Disab
Automatic Backup . Controls automatic initiation of a call setup attempt upon failure of the DDS network, defined as
detection of No Signal or Out-of-Service codes, or excessive bipolar violations. (Automatic dial attempts begin after the
Network Time-out expires.)
NOTE: The backup connection is made through the EIA-232 port.
Enab — Upon detecting a failure of the DDS network, the DSU waits for a period equal to DDS Timeout, and if the
DDS network is still down, it attempts to establish a dial backup connection to the number specified by
the Backup Directory pointer after the Network Time-out expires.
Disab — No automatic attempt is made to establish a dial backup connection.
Backup Dir: 1

Backup Directory . The DBM can store 10 dial strings or telephone numbers, identified by the numbers 1 through 10. This
display shows the identifier of the current default dial string to be used to set up a dial backup call for automatic backup
as described in the Auto Bckup configuration option, or when the backup command is received from the DCP or the
NMS.
Chang — Produces a data entry display for changing the directory entry identifier.
BckupOnCMI:Disab
Next Enab Disab
Backup on Control Mode Idle . This configuration option determines whether the DSU treats a control mode idle (CMI)
condition as a facility alarm to trigger automatic dial backup. Configuration option Auto Bckup must be enabled.
Enab — Upon detecting CMI for 250 to 500 milliseconds from the network, the DSU attempts to establish a dial
backup connection to the router after the DDS Time-out expires. When enabled, CMI will also generate a
Facility Alarm (FA). Do not use this configuration option if the DSU is configured to generate CMI.
Disab — No attempt is made to establish a dial backup connection if CMI is detected.
AutoRestor:Disab
Next Enab Disab
Automatic Restoration . Controls whether the DSU automatically terminates the dial backup call when the DSU
determines that the DDS circuit has been returned to service.
When DTRCallCon is enabled (set to Orig or Ansr), disable AutoRestor .
Enab — Restoral of the DDS circuit triggers automatic restoration (after the Restoration Time-out expires).
Restoral of the DDS circuit does not trigger automatic restoration. Disable when DTRCallCon is enabled.
Disab —
NtwkTimOut: 0:20 for a control DSU, 01:00 for a tributary DSU
Next Chang Prev
Network Time-out . Length of time the DDS network must remain out of service before the dial backup call attempt
sequence is made. This configuration option only has an effect if Auto Bckup is set to Enab. When configured for
nondisruptive diagnostics or rate adaption, this configuration option must be set to greater than or equal to 20 seconds.
Chang — Calls up a data entry display for changing the current value which can range from 1 second to
30 minutes. The cursor has two positions: a minutes field with a range of 0 to 29, and a seconds field with
a range of 00 to 59.
