Multipoint Backup Addressing
For a central-site multipoint dial backup configuration,
the digital bridge is controlled by the control DSU. Each
central-site DBM-V, DBM-S, or DBM-D in the
COMSPHERE 3000 Series Carrier has its own physical
address, which is determined by the carrier number/slot
number and used only for commands issued from the
SDCP. In addition, each DBM-V, DBM-S, or DBM-D has
a unique network address in the 1 to 255 range.
When not in dial backup, the tributary DBMs have
network addresses under the control DSU and at the same
level as the tributary DSU ( Figure 4-32 ). The term under,
as used here, means that the sequential address begins
with the control channel, followed by the slash delimiter
and the DSU network address, followed by the slash
delimiter and the tributary DBM network address; e.g.,
1/1/4 in Figure 4-32. When in dial backup, the tributary
DBMs retain the same address and are also addressable as
tributaries of the central-site DBM-Vs, DBM-Ss, or
DBM-Ds (
Figure 4-33
).
During dial backup, remote commands are routed
through the digital bridge and the DBM-Vs, DBM-Ss, or
DBM-Ds to the tributary DSUs or DBMs. The central-site
bridge supports nondisruptive ( NonD ), mixed ( Mixed ),
and disruptive ( Disr ) diagnostic types ( Diag Type ). The
Disruptive Diagnostic Type ( Disr Type ) should be set to
3600e, or Br56 for switched 56 kbps dial backup.
