5.7 G.772 Monitor
In this application, only 14 transceivers are functional and two transceivers are used for nonintrusive monitoring of
input and output of the other 14 channels. Channel 9 is used for 10 to 16 channels and Channel 1 is used for 2 to 8
channels. G.772 monitoring is configured by
GMC
Registers (
Table 6-9
). While monitoring channel 1 can be
configured in remote loopback and the monitored signal can be output on TTIP1 and TRING1. While monitoring
channel 9 can be configured in remote loopback and the monitored signal can be output on TTIP9 and TRING9.
5.8 Loopbacks
The DS26334 provides four loopbacks for diagnostic purposes: analog loopback, digital loopback, remote
loopback, and dual loopback. Dual loopback is accomplished by turning on digital loopback and remote loopback at
the same time.
5.8.1 Analog Loopback
The analog output of the transmitter TTIP and TRING is looped back to RTIP and RRING of the receiver. Data at
RTIP and ring is ignored in analog loopback. This is shown in
Figure 5-10
.
