A Logic 0 on this Bit Will Cause the M23 Stuffing to be
Determined by the External Stuff Request; Otherwise,
Fixed Stuffing is Used.
A Logic 1 of this Bit will Enable M13 to Receive and Out-
put Ds3 Payload Through a Serial Link.
The P Bits and, in CBP Mode, the CP Bits in the DS3
Frame Immediately Following Each 0 to 1 Transition of the
Input SMPR_BER_INSERT
Bit is Set to 1.
This Bit is Used Only in the C-Bit Parity Mode. In this
mode, if it is 0, the second c-bit of each ds3 frame, c2, Is Set
To 1. Otherwise, the transmit value of C2 is input through pin
TCBDATA (E12).
This Bit is Used Only in the C-Bit Parity Mode. In this
mode, if it is 0, the unused C bits of each DS3 frame (the
fourth through sixth and the sixteenth through twenty-first) are
set to 1. Otherwise, the transmit values of these bits are input
through pin TCBDATA (E12).
Bit During Normal Transmission.
This Bit is Used to Force Errors in the Transmitted DS3
FEBE Indication. If the Bit is Set, all DS3 Frames are
Transmitted with the FEBE Bits Set to 000.

Ones by Setting M13_TFEAC_CTL to 00.
by setting M13_TFEAC_CTL to 01, and M13_TFEAC_CODE
= x5x4x3x2x1x0, where x5x4x3x2x1x0 Is the appropriate
value for the alarm or status codeword.
In order to activate a loopback, the user may set
M13_TFEAC_CTL = 11, And M13_TFEAC_CODE =
x5x4x3x2x1x0, where x5x4x3x2x1x0 Is the Appropriate value
for the loopback codeword. The M13 will then transmit 10 rep-
etitions of the activate codeword, 0 000111 0 11111111, fol-
lowed by 10 repetitions of 0 x5x4x3x2x1x0 0 11111111. After
transmitting this 40 octet sequence, it will set

In order to deactivate a loopback, the user may set
M13_TFEAC_CTL = 10, and M13_TFEAC_CODE =
x5x4x3x2x1x0, where x5x4x3x2x1x0 is the appropriate value
for the loopback codeword. The M13 will then transmit 10 rep-
etitions of the deactivate codeword, 0 011100 0 11111111, fol-
lowed by 10 repetitions of 0 x5x4x3x2x1x0 0 11111111. After
transmitting this 40 octet sequence, it will set
M13_TFEAC_DONE to 1.
