Reserved.
In the M23 mode (M13_M23_CBP = 1
in each received DS3 M-subframe are checked for loopback
requests. If the third C bit differs from the first and second C
bits in the yth M-subframe for 5 successive DS3 frames,
M13_DS2_LB_DETy is set to 1. M13_DS2_LB_DETy is
cleared when the third C bit does not differ from the first two C
bits in subframe y for 5 successive DS3 frames. In the C-bit
parity mode, M13_DS2_LB_DETy is fixed at 0.
Reserved.
The M13_DS2_RSV_RCVy bit changes state only after the
reserved bit in the E1 mode (M13_DS1_E1Ny = 0) is received
as the same value for 4 consecutive DS2 frames. DS2 frame
periods are not counted while M13_DS3_OOF = 1. It is set
equal to the reserved bit.
Reserved.
A logic 1 of M13_DS2DMX_LOCy bit indicates that loss of
clock is detected on the DS2 clock input, XC_DS2DMXCLKy.

The M13_DS1_LOCx bits indicate when loss of clock is
detected on a low-speed clock input, XC_DS1CLKx.
