Easy to Create Very Large Routers

Creating very large routers in the Trinix design is accomplished by using
special circuitry for simple and cost effective expansion. For example,
Using passive port expansion modules, a 1024 x 1024 router can be built
using Grass Valleys 512x512 or 512x1024 Routing switchers.

Using the 512x512 Routing Switcher

A 1024 x 1024 router can be built using four 512 x 512 frames coupled
together with the passive port expanders in four equipment racks. These
expanders can also be used to provide dual or quad, non-inverting outputs.

Using the 512x1024 Routing Switcher

A 1024 x 1024 router can be built using two 512 x 1024 frames coupled
together with the passive port expanders in two equipment racks.

Control Systems

The Trinix router can be controlled by a variety of control systems. The
Trinix router can be controlled by the Jupiter Facility Control System using
a Crosspoint bus connection (see

Glossary

) and either a VM-3000 System

Controller or a CM-4000 System Controller. The VM and CM controllers
can receive switching commands from a variety of serial sources, including
Jupiter control panels or an automation computer. Trinix can also be con-
trolled using a direct Ethernet (“CPL”) integration with the Grass Valley
Encore or SMS 7000 control system.

The Symmetric Trinix Frame

Trinix was designed with reliability and serviceability in mind. Each frame
has redundant power supplies, redundant fans, and a physical topology
that is designed to maximize cooling. Mission critical modules are front
loading and hot swappable.

Power Supplies

All Trinix frames accommodate a minimum of two load-sharing power
supplies and have two AC inputs. This duplication allows for full redun-
dant operations.

Each power supply is front loading, hot swappable, and has its own fans
for cooling. The 128 x 128 frame includes two fan modules, the 256 x 256
frame includes three, and a 512 x 512 frame includes six fan modules.
