Matrix Switch test tools

For the purpose of testing and troubleshooting the STM-1 link, the DS0 Mapping definitions, and H.110 bus connectivity, the Model 6511RC Matrix Switch offers the following tool sets:

•Loopback test modes for the Matrix Switch STM-1 port

•SDH Section Trace and SDH Path Trace functions for the STM-1 link The following sections describe these tool sets in detail.

Loopback test modes for the STM-1 port

The Matrix Switch provides the following diagnostic loopback test modes for the STM-1 port:

•SDH facility loop (see section “Facility Loop [sonetFacilityLoop(1)]” on page 87)

•SDH terminal loop (see section “Terminal loop [sonetTerminalLoop(2)]” on page 88)

•H.110 loop (see section “Other Loop [sonetOtherLoop(3)]” on page 90)

The facility and terminal loops are specified by the SDH protocol. The H.110 loop is proprietary to the Fore- Front Matrix Switch, and fulfills the SDH specification for a third vendor-defined loop.
