error count, and a clear error count option. See Figure 6-7 on page 6-5. Selecting Data Mode will cease the

transmission of the QRSS pattern and start transmission of a loop down pattern as previously described.

NOTE

When in CSU Loopback w/BERT, only the Data Mode for the T1 under

test may be selected. Selecting any other option results in an error

message.

Figure 6-7. Loopback Menu with BERT Selected

Line BERT

A Line BERT enables the MX2800 to perform a “head-to-head” BERT test toward the CSU. Selecting Line

BERT

replaces all incoming network traffic for the selected T1 with an unframed QRSS pattern toward the

CSU. When Line BERT is selected, additional menu items appear and show the state of pattern synchroni-

zation, cumulative error count, and a clear error count option. Selecting Data Mode ceases QRSS pattern

generation and substitution of the incoming data stream.

NOTE

When in Line BERT mode, only the Data Mode option for the T1 under

test may be selected. Selecting any other option will result in an error

message being displayed.
