3.3.10 G.772 NON-INTRUSIVE MONITORING
to monitor the data received or transmitted in any one of the remaining chan-
nels. The MON[3:0] bits (GCF1, 60H) determine which channel and which
direction (transmit/receive) will be monitored. The monitoring is non-intru-
sive per ITU-T G.772.

RCLK1, RD1/RDP1 and RDN1. If Channel 1 is configured to Remote Loop-
back while in the Monitoring mode, the monitored data will be output on
TTIP1/TRING1.
