If M13_SEL_DS2_LBy = 1, the DS2 Signal from Time Slot y
in the Received DS3 Signal is Looped Back into Time
Slot y of the Transmitted DS3 Signal.
Reserved.
A logic 1 of these Bits Means that the Received DS2 Sig-
nals are Retimed by the Rising Edge of the Associated
Clocks. A logic 0 means that the data is retimed by the falling
edge. When used in the demand clocking mode of the M23
mapping, M13_RDS2_EDGE[7:1] = 1 should be set if the
delay from the output clock to the incoming data (the maximum
should be less than 8 STS-1 clock cycles) is less than 4 STS-1
clock cycles; otherwise, M13_RDS2_EDGE[7:1] = 0 should be
used.
Reserved.
In the Demand Clocking Mode of the M23 Mapping, this
Register Provides an Extra Clock Edge Selection Capabil-
ity, in Addition to M13_RDS2_EDGE[7:1], for Retiming
Input DS2 Data. It should normally be set to logic 1 (default).
A logic 0 is suggested only to be used with
M13_RDS2_EDGE[7:1] = 0 when necessary.
Reserved.
If M13_DS2_OUT_IDLEy = 1, the Output from DS2 Output
Selection Block y is Held Low.
Reserved.
If M13_DS2_OUT_IDLEy = 0
Bit Causes DS2 AIS to be Output From the DS2 Output
Selector y; Otherwise, the DS2 Signal From Time Slot y in
the Received DS3 Signal will be Output.
