Preliminary Information

Bit
Name
Functional Description
7
BPVE
Bipolar Violation Error Insertion.
A zero-to-one transition of this bit
inserts a single bipolar violation
error into the transmit PCM 30 data.
A one, zero or one-to-zero transition
has no function.
6
CRCE
CRC-4 Error Insertion.
A zero-to-
one transition of this bit inserts a
single CRC-4 error into the transmit
PCM 30 data. A one, zero or one-to-
zero transition has no function.
5
FASE
Frame Alignment Signal Error
Insertion.
A zero-to-one transition
of this bit inserts a single error into
the time slot zero frame alignment
signal of the transmit PCM 30 data.
A one, zero or one-to-zero transition
has no function.
4
NFSE
Non-frame
Error Insertion.
A zero-to-one
transition of this bit inserts a single
error into bit two of the time slot zero
non-frame alignment signal of the
transmit PCM 30 data. A one, zero
or one-to-zero transition has no
function.

Signal
3
LOSE
Loss of Signal Error Insertion.
If
one, the MT9075A transmits an all
zeros signal (no pulses) in every
PCM 30 time slot. If zero, data is
transmitted normally.
2
PERR
Payload Error Insertion.
A zero-to-
one transition of this bit inserts a
single error in the transmit payload.
A one, zero or one-to-zero transition
has no function.

Unused.
0
DBNCE
Debounce Select.
This bit selects
the debounce period (1 for 14
msec.; 0 for no debounce). Note:
there may be as much as 2 msec.
added to this duration because the
state change of the signalling
equipment is not synchronous with
the PCM 30 signalling multiframe.

2
LOS/LOF
Loss of Signal or Loss of Frame
Selection.
If one, pin LOS (pin 61 in
PLCC, 57 in MQFP) will go high
when a loss of signal state exits
(criteria as per LLOS status bit on
page 03H address 18H). If low, pin
LOS will go high when either a loss
of signal (LLOST =1) or a loss of
basic frame alignment state exits
(bit SYNC on page 03H address
10H is zero).
1
ADSEQ
Digital Milliwatt or Digital Test
Sequence.
If one, the A-law digital
milliwatt analog test sequence will
be selected by the Per Time Slot
Control bits TTST and RTST (on
page 07H and 08H). If zero, the
PRBS 2
15
-1 bit error rate test
sequence will be selected by the
Per Time Slot Control bits TTST and
RTST. The PRBS generator is reset
whenever this bit is set to 1.
0
GCI/ST
GCI or ST-BUS Frame Pulse.
If
one, the MT9075A will transmit or
receive a GCI frame pulse on pin
F0b (pin 46 in PLCC, 34 in MQFP).
If zero, the MT9075A will transmit or
receive an ST-BUS frame pulse on
F0b.
