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.
