4.1. SYSTEM OVERVIEW
The EQT router is a matrix router that provides a simple cost-effective solution for small router
applications. The EQT consists of 32 or 16 equalized inputs and 32, 24, 16, 8 or 4 reclocked outputs.
Each input and each output is interfaced through a common crosspoint that is controlled by the main
processing unit.
The processing unit interfaces the various control options such as Q-Link, Ethernet and serial with the
crosspoint, allowing full control of the routing resources. The processing unit also provides a video
reference to the crosspoint to maintain clean switching on the switch line.
The major components of the EQT router are shown below in Figure 4-1, Figure 4-2 and Figure 4-3.
