Invert Transmit Clock
Possible Settings: Disable, Enable
Default Setting: Disable
When configured as the STU-C and Transmit Clock Source is set to External,
specifies whether the clock supplied by the the unit on the TXC interchange circuit DB
(ITU-T 114) is phase inverted with respect to the Transmitted Data interchange circuit

between the unit and the DTE causes errors.
Send All Ones on Data Port Not Ready
Possible Settings: Both, Disable, DTR, RTS

Specifies the action taken on the synchronous data port when an LOS (Loss Of
Signal) alarm is received on the DSL interface.
Network Initiated Data Channel Loopback
