Functional Description
7
- - Reserved. Must be kept at 0 for normal operation.
6
TE Transmit E bits. When zero and CRC-4 synchronization is achieved, the E-bits transmit the
received CRC-4 comparison results to the distant end of the link, as per G.703. That is, when
zero and CRC-4 synchronization is lost, the transmit E-bits will be zero. If one, and CRC-4
synchronization is lost the transmit E-bits will be one.
5 TAIS16 Transmit AIS Time Slot 16. If one, an all ones signal is transmitted in time slot 16. If zero,
time slot functions normally.
4
TxAO Transmit All Ones. When low, this control bit forces a framed or unframed (depending on
the state of Transmit Alarm Control bit 0) all ones to be transmit at TTIP and TRING.
3
Einv Ebit Error Inversion. When zero, received Ebits set to zero are counted in the Ebit error
counter and interrupt generator. When one, Ebits set to one are counted in the Ebit error
counter and interrupt generator.
2-0
- - - Unused.
