TxOn
Transmit ON/OFF
Upon power up, the transmitters are powered off. This bit is used
to turn the transmitter for this channel On or Off if the TxON pin is
pulled "High". If the TxON pin is pulled "Low", all 16 transmitters
are powered off.
0 = Transmitter is Powered OFF
1 = Transmitter is Powered ON

E1Arben
E1 Arbitrary Pulse Enable
This bit is used to enable the Arbitrary Pulse Generator for shaping
the transmit pulse shape when E1 mode is selected. If this bit is
set to "1", this channel will be configured for the Arbitrary Mode.
Each channel is individually controlled by programming the chan-
nel registers 0xN08 through 0xN0F, where n is the number of the
channel.
"0" = Disabled (Normal E1 Pulse Shape ITU G.703)
"1" = Arbitrary Pulse Enabled
