M1 Error Count in Bit or Block. When set to
0, M1 check logic will count bit errors. When set
to 1, block errors are counted. Only
M1BITBLKCNT[C] is valid for STS-48/STM-16.
Reserved. These bits must be written to their
reset default value (00).
number of consecutive all-zeros/-ones pattern
detected to declare receive LOS state for each
channel. The time scale is in steps of 8 (for
STS-3/STM-1 and STS-12/STM-4) or 32
(STS-48/STM-16) bits at a time. Only
LOSDETCNT[A][12:0] is valid for STS-48/
STM-16.
Receive Reference Sync Select. Select refer-
ence output from channel A (00), B (01), C (10),
and D (11).
Receive Reference Sync Enable. When set to
0, the receive 8 kHz (50% duty cycle) sync out-
put, RxREF (pin AK3), is placed in the high-
impedance state.
Reserved. These bits must be written to their
reset default value (000000000).
Receive TOAC Frame (Sync) Inhibit Channel
A. When set to 1, the TOAC sync output,
RxTOHF (pin AK4), is placed in the high-imped-
ance state.
Receive TOAC Clock Inhibit Channel A.
When set to 1, the TOAC clock output,
RxTOHCK (pin AK5), is placed in the high-
impedance state.
Receive TOAC Data Inhibit Channel A. When
set to 1, the TOAC data output, RxTOHD (pin
AL2), is placed in the high-impedance state.
Receive TOAC Odd or Even Parity Insert
Channel A. When set to 1, the output TOAC
parity bit is even. When set to 0, the parity is
odd.
