Model 6511RC User Manual 

5 • Troubleshooting and maintenance

To understand how these test modes work, you must first understand the basic architecture of the Model 
6511RC’s TDM mapping functions. The TDM mapping function provides the connection between the 
STM-1 port and the H.110 bus. Within the TDM mapper (see 

figure 60

) data passes between the SDH fram-

ing processor and the H.110 framing processor. 

Figure 60. Matrix Switch TDM mapping architecture

The various loopback test modes route data through one or both of these framing processors, with the data 
path making a U-turn in one framer or the other. Subsequent paragraphs describe the details of each loopback 
test mode for the STM-1 port.

Facility Loop [sonetFacilityLoop(1)]

You can use the facility loop to test and troubleshoot the operation of the STM-1 link, including the Matrix 
Switch’s STM-1 port and the fiber-optic or coaxial cables connected to it.

The facility loop (see 

figure 61

) returns data received from the SDH facility (the STM-1 link) back to the same 

SDH facility. In other words, when the Facility Loop is activated, the Matrix Switch receives data from the 
STM-1 link and transmits the (unmodified) data back to the STM-1 link.

The U-turn for the facility loop occurs within the SDH framer on the Matrix Switch. The data path for the 
facility loop traverses the SDH framer, but not the H.110 framer. Data enters the Matrix Switch at the STM-1 
receive port, and enters the SDH framer where it loops back toward the STM-1 link, leaving the Matrix switch 
at the STM-1 transmit port.
