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.
