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. 
Note: For detailed information about Staging Bridges Support, see Staging Bridges: 
Reduce Network Message Traffic and Improve DHCT Staging Efficiency

Support for the Netcrypt Bulk Encryptor 
The Netcrypt Bulk Encryptor optional feature is a powerful encryption engine 
designed for use in Gigabit Ethernet (GbE) transport networks. The Netcrypt Bulk 
Encryptor encrypts digital broadcast and narrowcast transport streams across 
multiple headends and can use up to three distinct conditional access systems 
(CASs). 
Note: Broadcast refers to one signal going to many sites; narrowcast refers to one 
signal going to a select group of sites. 
The Netcrypt Bulk Encryptor has a maximum throughput of 4 Gbps. It is capable of 
encrypting as many as 4000 input programs into individual transport streams 
suitable for digital broadcast or multicast sessions. The Netcrypt Bulk Encryptor also 
provides the technology to multicast both the input and the output streams. 
The Netcrypt Bulk Encryptor enables you to maximize your bandwidth usage and 
provides countless programming options that will enhance your service to your 
customers as well as increase your revenue potential. 
Note: If you would like to purchase or activate this separate software product for 
your system, contact your Cisco marketing representative.
