5 • DS0 Mapping Model 6511RC Matrix Switch Administrators’ Reference Guide
30 Introduction
Introduction
The Model 6511RC Matrix Switch concentrates the traffic capacity of up to 63 E1 lines for delivery over a
155.52 Mbps optical or electrical STM-1interface. The Matrix Switch provides an interface to the TDM mid-
plane bus within the ForeFront chassis. The total capacity of the TDM midplane bus is 4096 simplex DS0s,
the equivalent of 64 E1s. Each DS0 channel can be mapped in either direction, transmitting to the TDM mid-
plane bus or receiving from the TDM midplane bus. The 6511RC places the DS0 traffic into the STM-1 mul-
tiplexer for transport over the SDH network. To place DS0 traffic from the TDM midplane bus to the STM-1
you must define a DS0 mapping (also called an internal connection or cross-connection). The source is DS0 traffic
on the H.110 side, and the destination are STM-1 virtual containers. The 6511RC’s DS0 Mapping Overview
window (see
figure 17 ) provides the means for managing (mapping) internal connections.
Figure 17. DS0 Mapping Overview window
Devices connect to the 6511RC via the STM-1 optical or electrical interface, and H.110 ports. (A device will
connect to an H.110 port via the 6511RC’s interface to the TDM midplane bus in the cPCI chassis mid-
plane). Each DS0 mapping defines a one-to-one connection between a selected number of timeslots on one
H.110 port and an E1 port or a TU-12. Use the DS0 Mapping management web page to define these DS0
mappings (internal connections) and to view previously defined mappings.

The DS0 Mapping Configuration window and related windows provide the means for you to manage the
6511RC DS0 mapping subsystem. To display the DS0 Mapping Configuration window (see
figure 17 ), on the
6511RC Configuration Menu, click the DS0 Mapping link.
