Loopback Activate Code Length—Selects the number of loopback pattern bits from LBA
[addr 043] that are compared to received data. This is done in order to determine whether a
Loopback Activate Code [LOOPUP; addr 048] has been detected. LOOPUP is recovered if the
received data pattern contains fewer than 63 bit errors in a 24 ms period, or lost if 64 or more
bit errors are detected in a subsequent 24 ms period. F-bits that overwrite or are inserted into
the loopback pattern are not counted as bit errors. Accurate code detection is provided on lines
with up to 1E-3 BER.
First bit expected of LOOPUP pattern
Second bit expected of LOOPUP pattern
Third bit expected of LOOPUP pattern
Fourth bit expected—Last bit if UP_LEN selects a 4-bit pattern
Fifth bit expected—Last bit if UP_LEN selects a 5-bit pattern
Sixth bit expected—Last bit if UP_LEN selects a 6-bit pattern
Seventh bit expected—Last bit if UP_LEN selects a 7-bit pattern
First bit expected of LOOPDN pattern
Second bit expected of LOOPDN pattern
Third bit expected of LOOPDN pattern
Fourth bit expected—Last bit if DN_LEN selects a 4-bit pattern
Fifth bit expected—Last bit if DN_LEN selects a 5-bit pattern
Sixth bit expected—Last bit if DN_LEN selects a 6-bit pattern
Seventh bit expected—Last bit if DN_LEN selects a 7-bit pattern
