Bits
0
Description
Loss of Transmit Superframe Alignment (LTSFA).
A 1 indicates superframe alignment pattern in
the facility data link input XFD as defined for SLC-96 is errored. Only valid for SLC-96 mode. This bit
is 0 in all other modes.
Status Counter Overflow (SCO).
A 1 indicates one of the status counters has reached the all ones
state.
Loss of Biframe Alignment (LBFA).
A 1 indicates biframe alignment pattern (alternating 1-0 in bit 2
of time slot 0 of each frame) in the receive system data is errored. This alignment pattern is required
when transmitting the Si or Sa bits transparently. Transmitted line data on the XPD and XND output
will be corrupted while in this state. Only valid in CEPT mode, this bit is forced to 0 while in the double-
NOT-FAS mode. This bit is 0 in all other modes or when programmed for double NOTFAS mode.
Biframe Alignment Established (BFA).
A 1 indicates the transmit framer has established a biframe
alignment for the transmission of transparent Si and/or Sa bits from the system data. Only valid in
CEPT mode. This bit is 0 in all other modes
This Bit Is Reserved and Set to 0.
Auxiliary Pattern (AUXP).
A 1 indicates that the receive framer has detected a unframed AUXP pat-
tern. If the receive framer is no longer receiving an unframed AUXP, then this bit is cleared on read.
The receive the detection of a valid AUXP.
Receive Continuous E Bit = 0 (RCEBIT).
A 1 indicates that the receive framer has detected receive
continuous E bit = 0 for at least five seconds.
Receive CRC-4 100 (400) ms Timer Expirer.
