Patton electronic user manual Model 6511RC Matrix Switch major functions and interfaces

Model 6511RC User Manual 1 • Introduction

Figure 2 shows the major functions and connections the Matrix Switch provides within the ForeFront chassis. Each Model 6511RC enables service providers to perform SDH multiplexing and demultiplexing with any-to- any timeslot mapping for up to 2048 DS0 channels. The on-board TDM multiplexer can map any of the 4096 DS0 timeslots on the TDM bus in the chassis midplane to any of the 2048 DS0s on the STM-1 uplink. Each DS0 consists of a 64 kbps communication channel, or timeslot. The integrated SDH aggregator combines DS0 channels into E1 signal streams, then maps those E1s into a STM-1 signal for high-speed transmission on the SDH trunk.

The Model 6511RC provides an Ethernet-switching fabric for packet-based management and user traffic tra- versing the ForeFront chassis. The powerful Ethernet switch connects the high-speed packet-switched bus in the ForeFront chassis midplane with two 10/100/1000 Ethernet uplinks. Offering fast Ethernet switching and flexible timeslot aggregation, the Model 6511RC Matrix Switch enables the ForeFront AIS system to deliver a surprisingly compact, high-speed trunking solution at very low cost.
