Point-to-Point Configuration
To set up aggregate switching for a single-port,
point-to-point configuration, enable the following
configuration options:
•
DSU Configuration Options
(Table 6-5):
– AggrSwitch (Aggregate Switch) must be
enabled.
– AgSw Timing (Aggregate Switch Timing) must
be set to the appropriate timing source to be used
during dial backup.
•
DBM Configuration Options
(Table 6-9); for the
DBM, DBM-V, DBM-S, DBM-D, or other external
dial backup unit (DBU) connected to the switched
aggregate port:
– Rate(Kbps) (DBM Rate) must be set to the same
rate as the DSU rate.
– Diag Type (Diagnostic Type – Diagnostic DBM
Options) must be set to None or Disr.
To establish aggregate switching dial backup from the
DCP, run backup from the control DSU and command the
DBM-V, DBM-S, or DBM-D to dial and go into Dial
mode. From the 6800 Series NMS, use the Standby
Facility (sf) and Dial commands. The 6700 Series NMS
software provides a Commands pull-down window to
access Standby Facility. Aggregate switching can also be
controlled automatically, enabling the Answer External
Backup (AnswExtBU) configuration option.
Refer to Figure 1-6 for a sample aggregate switched
backup for a point-to-point configuration. The control
DSU is configured so that AggrSwitch is enabled and
AgSw Timing is set to Aggr. In this example, the DSU
takes its timing from the Switched 56 DBM when in Dial
Backup mode.
Multipoint Configuration
To set up aggregate switching for a multipoint
configuration, enable the following configuration options:
•
DSU Configuration Options
(Table 6-5):
– AggrSwitch (Aggregate Switch) must be
enabled.
– AgSw Timing (Aggregate Switch Timing) must
be set to the appropriate timing source to be used
during dial backup.
•
DBM-V, DBM-S, DBM-D, or other external
DBM
Configuration Options
(Table 6-9):
– Rate(Kbps) (DBM Rate) must be set to the same
rate as the DSU rate (no rate adaption).
– Diag Type (Diagnostic Type – Diagnostic DBM
Options) must be set to None or Disr.
