Preliminary Information

Bit

Functional Description
7
HDLC0
HDLC0 Select.
If one, then HDLC0
is connected to the data link on
selected S
a
bits at a rate of 4, 8, 12,
16 or 20 kbits/sec. If zero, HDLC0 is
deselected and all HDLC0 interrupts
are masked.
6
HDLC1
HDLC1 Select.
If one, then HDLC1
is connected to time slot 16 in CCS
mode. If zero, HDLC1 is deselected
and all HDLC1 interrupts are
masked.
5
RxTRSP
Receive Transparent Mode.
When
this bit is set to one, the framing
function is disabled on the receive
side. Data coming from the receive
line passes through the slip buffer
and drives DSTo with an arbitrary
alignment. When zero, the receive
framing function operates normally.

MLBK
Metallic Loopback.
If one, then the
external RRTIP and RRING signals
are isolated from the receiver, and
TTIP and TRING are internally
connected to the receiver analog
input instead. If zero, metallic
loopback is disabled.
5
HDB3
High Density Bipolar 3 Encoding.
If zero, HDB3 encoding is enabled
in the transmit direction. If one, AMI
signal without HDB3 encoding is
transmitted.
HDB3
decoded in the receive direction.

always
4
MFRF
Multiframe Reframe.
If one, for at
least one frame, and then cleared
the MT9075A will initiate a search
for a new signalling multiframe
position. Reframing function is
activated
on
transition of the MFRF bit.

one-to-zero
3
DLBK
Digital Loopback.
If one, then the
digital stream to the transmit LIU is
looped back in place of the digital
output of the receive LIU. Data
coming out of DSTo will be a
delayed version of DSTi. If zero, this
feature is disabled.
2
RLBK
Remote Loopback.
If one, then all
bipolar data received on RRTIP/
RRING are directly routed to TTIP/
TRING on the PCM 30 side of the
MT9075A. If zero, then this feature
is disabled.
1
SLBK
ST-BUS Loopback.
If one, then all
time slots of DSTi are connected to
DSTo on the ST-BUS side of the
MT9075A. If zero, then this feature
is disabled. See Loopbacks section.
0
PLBK
Payload Loopback.
If one, then all
time slots received on RTIP/RRING
are connected to TTIP/TRING on
the ST-BUS side of the MT9075A
(this excludes time slot zero). If
zero, then this feature is disabled.
