Bits 3 to 0: G.772 Monitoring Control (GMC)
. These bits are used to select transmitter or receiver for
nonintrusive monitoring. Receiver 1 is used to monitor channels 2 to 8 of one receiver from RTIP2–
RTIP8/RRING2–RRING8 or of one transmitter from TTIP2–TTIP8/TRING2–TRING8. See
Table 5-9

Bits 7 to 0: Digital Loopback Control Channel
n
(DLBC
n
)
. When this bit is set, the LIU
n
is placed in digital
loopback. The data at TPOS/TNEG is encoded and looped back to the decoder and output on RPOS/RNEG. The
jitter attenuator can optionally be included in the transmit or receive paths.
