• Flashes once to indicate that a CRC error has

 

occurred (during normal operation) or bit errors

 

have occurred (during 511/511E tests).

TM

(Active Yellow) glows yellow to indicate that the

 

Model 1088/K has been placed in Test Mode. The

 

unit can be placed in test mode by the local user or

 

by the remote user. The TM LED will flash for

 

400 msec when a valid packet is received from the

 

Model 1001MC.

5.3 TEST MODES

The Model 1088 offers two proprietary loopback test modes, plus a built- in V.52 BER test pattern generator to evaluate the condition of the modems and the communication link. These tests can be activated phys- ically from the front panel.

Overview

Figure 11 below shows the major elements used in the loop-back and pattern tests available in the Model 1088. Each block has several func- tions. Following Figure 11 are descriptions that show how the elements are used during Test Modes.

Framer

The framer is used to determine the status of the line. In normal operation the framer transmits and expects to receive framed packets from the far end. If the framer receives framed packets from the far end, the DSL Link LED will be active. If framed pack- ets are not received, the DSL Link LED will be inactive. The restart procedure uses this information to determine if a valid connection
