7.2.7 Test Functions
The W6692 provides loop and test functions as follows:
-
digital loop via DLP bit in D_MODE register: In the layer 2 block, the transmitted 2B+D data
are internally looped (from HDLC transmitter to HDLC receiver), and in the PCM ports, the
transmitted B channels are internally looped (from PCM inputs to PCM outputs). The clock
timings are generated internally and are independent of the S bus timing. This loop function is
used for test of PCM and higher layer functions, excluding layer 1. After hardware reset,
W6692 will power down if S bus is not connected or if there is no signal on the S bus. In this
case, the C/I command ECK must be issued to power up the chip.
