Staging Out-Of-Band Bridges

Overview

The traditional staging method for DHCTs involves the DNCS sending EMMs to
every bridge on the DNCS network when operators stage DHCTs with the reverse
plant disabled.
Note: Staging Out-Of-Band Bridges functionality is available beginning with the
following System Releases:
SR 2.7/3.7/4.2

CV 3.4

What Are Staging Bridges?
Staging bridges are a subset out-of-band (OOB) bridge population of the DBDS that
DNCS operators assign the task of DHCT staging. This subset (which can consist of
QPSKs, CMTSs, or both) receives all staging message traffic instead of having every
QPSK/CMTS in the network receive staging message traffic.
Using staging bridges eliminates the staging communication from being broadcast
throughout the entire network (to every QPSK /CMTS hub). Staging bridges reduce
the processing load on the DNCS and reduces the amount of network message traffic
when you perform staging.
