Transmit Set Delay Bits 7-0. Writing to this register forces a one time setting
of the delay through the transmit slip buffer. Delay is defined as the time
interval between the write of the transmit STBUS channel containing DS1
timeslot 1 and its subsequent read. Delay is modified by moving the position
of the internally generated DS1 frame boundary.Delay (when set) will always
be less than 1 frame (125 uS). This register must be programmed with a
non-zero value (such as 0FH).
Table 29 - Transmit Message Word (T1)
Transmit Message Bits 7 - 0. The contents of this register are transmitted
into those outgoing DS1 channels selected by the Per Time Slot Control
registers.
Bipolar Violation Error Insertion. A zero-to-one transition of this bit inserts
a single bipolar violation error into the transmit DS1 data. A one, zero or
one-to-zero transition has no function.
CRC-6 Error Insertion. A zero-to-one transition of this bit inserts a single
CRC-6 error into the transmit ESF DS1 data. A one, zero or one-to-zero
transition has no function.
Terminal Framing Bit Error Insertion. A zero-to-one transition of this bit
inserts a single error into the transmit D4 Ft pattern or the transmit ESF
framing bit pattern (in ESF mode). A one, zero or one-to-zero transition has
no function.
Signal Framing Bit Error Insertion. A zero-to-one transition of this bit
inserts a single error into the transmit Fs bits (in D4 mode only). A one, zero
or one-to-zero transition has no function.
Loss of Signal Error Insertion. If one, the MT9074 transmits an all zeros
signal (no pulses). Zero code suppression is overridden. If zero, data is
transmitted normally.
