BPVE
Bipolar
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.

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.

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.

LOSE
Loss of Signal Error Insertion
. If
one, the MT9074 transmits an all
zeros signal (no pulses) in every
PCM 30 time slot. When HDB3
encoding is activated no violations
are transmitted. If zero, data is
transmitted normally.

LOS/

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. A
loss of signal is defined as either
receipt of a signal attenuated
below the analog loss of signal
threshold (selectable as 20 dB or
40 dB below nominal) or receipt
of 192 consecutive 0’s. If low, pin
LOS will go high when either a
loss of signal or a loss of basic
frame alignment state exits (bit
SYNC on page 03H address 10H
is zero).
