Received Payload Type Field—These 3 bits store the pattern of the payload-type field in an
MA byte (bits 3–5). No interrupt is issued to report any change in the content of this field.
RxMAPT [1] is the first bit received from the line.
Received Payload Dependent/Multiframe Indicator Field—These 2 bits store the pattern of the
payload-dependent/multiframe indicator in MA byte (bits 6–7). No interrupt is issued to report
any change in the content of this field. RxMAPD [1] is the first bit received from the line.
Received Timing Marker Bit Field—This bit contains the timing marker bit in an MA byte (bit
8) information. It is valid only when SSM mode is disabled, i.e., when SSMEn bit in Feature4
register is low. No interrupt is issued to report any change in the content of this field.
Received SSM Field—These 4 bits store the pattern of SSM field in MA byte (bit 8 collected
from 4 frames). The SSM bits are collected from 4 consecutive frames and arranged according
to the multiframe indicator field (SSM [1] is the MS bit that is received when MI = 00, etc.).

E3-832 MA Fields Registers
The E3-832 MA Fields registers collect data of specific fields from E3-G.832 type
frames. In DS3 and E3-G.751 modes, they are ignored.
E3-G.832 SSM Field Status Register (SR07i)
The E3-G.832 SSM Field Status register (SR07i) is valid only when SSM mode is
enabled, i.e., when SSMEn bit in Feature Control register4 is high.
E3-G.832 MA Fields Status Register (SR06i)
