TIMEMK
The TIMEMK bit determines the state of the Timing Marker bit (bit 8 of the G.832
Maintenance and Adaptation byte). When TIMEMK is set to logic one, the Timing Marker bit
in the MA byte is set to logic one. When TIMEMK is set to logic zero, the Timing Marker bit
in the MA byte is set to logic zero.
TUMFRM[1:0]
The TUMFRM[1:0] bits reflect the value to be inserted in the Tributary Unit Multiframe bits
(bits 6, and 7 of the G.832 Maintenance and Adaptation byte). These bits are logically ORed
with the TUMFRM[1:0] overhead signals from the TOH input before being inserted in the
MA byte.
PTYPE[2:0]
The PTYPE[2:0] bits reflect the value to be inserted in the Payload Type bits (bits 3,4,5 of the
G.832 Maintenance and Adaptation byte).
FEBE
The FEBE bit reflects the value to be inserted in the FEBE indication bit (bit 2 of the G.832
Maintenance and Adaptation byte). The FEBE bit value is logically ORed with the FEBE
indications generated by the FRMR for any detected BIP-8 errors. When the FEBE bit is
logic one, bit 2 of the G.832 MA byte is set to logic one; when the FEBE bit is logic zero, any
BIP-8 error indications from the FRMR causes bit 2 of the MA byte to be set to logic one.
