Select Transmit Tributary Monitoring for receive test unit
This bit selects the T1/E1 tributary observed by the test unit receiver.
The test unit can be connected to the upstream T1/E1 tributary (T1/E1
tributary going towards the DS3 interface) or to the downstream T1/E1
tributary (T1/E1 tributary coming from the DS3 interface).

Convert all B3ZS codeword patterns to “000” regardless of
polarity.
Convert codeword only if alternate violation polarity rule is
satisfied.
Interrupt vector flags are set when corresponding condition has
changed.
Interrupt vector flags contain actual status of condition.
Monitor downstream T1/E1 tributary.
Monitor upstream T1/E1 tributary.
