I
Receiver Negative Bipolar Input – Channel_n:
The Receive Section of Channel_n uses this input pin, along with RTIP_n to receive
the bipolar line signal from the Remote E1 Terminal.
V11
TxON
I
Transmit ON/OFF Input:
Upon power up, all of the transmitters are powered off. If the TxON pin is pulled
"High" all 21 transmitters are powered on. Individual Channels can be powered
down by connecting TxClk_n "Low" and with TPOS_n/TNEG_n data applied to that
Channel_n.
N
OTE
:
Internally pulled "Low" with a 50k
resistor.
