Staging Bridges Support
The current staging method involves sending all EMMs to every bridge on the
DNCS network when operators stage DHCTs with the reverse plant disabled (one-
way staging). The primary purpose of Staging Bridges support is to provide the
capability for operators to identify a specific bridge (hub) on which staging is to be
performed. Then, staging communications are delivered to the specific bridge used
for staging. Staging Bridges Support eliminates the need to broadcast staging
communications (EMM distribution) throughout the entire network, and it reduces
the processing load on the DNCS when staging is performed.
