Definitions
Application Module – A module inserted into the front of the chassis that performs a prescribed set of independent
functions (e.g., modulator, upconverter).
Rear Interface Module (RIM) – A module inserted into the rear of the chassis to configure a slot for a specified
application module.
Transmission Network Control System - TNCS is a comprehensive element management system that provides
centralized end-to-end monitoring and control of broadband transmission networks. TNCS is a mixture of software
and hardware components that is used as a headend, hub, and HFC equipment status monitoring and
management tool. Minimizing downtime and increasing the broadband network reliability are the primary objectives
of TNCS.
Controller Module – The module that resides in the left-most slot (Slot

Controller Module – The module that resides in the left-most slot (Slot
∅), which controls back-up functions and
communications between application modules. It also provides the Status Monitoring and Control (SMC) interface
necessary to communicate with external network management programs such as Scientific-Atlanta’s TNCS
product.
Automatic Backup – The feature that allows the controller module to sense a malfunction in any application
module in that chassis and re-route the input/output signals to a designated back-up application module.
Plug and Play – The feature that allows instant replacement and configuration of a faulty application module
without requiring user set-up or power interruption of an entire chassis.
