Receive TIP Input
These input pins along with the corresponding RRing_n input pin function as the
Receive DS3/E3/STS-1 Line input signal for a given channel of the XRT73R12.
Cconnect this signal and the corresponding RRING_n input signal to a 1:1
transformer.
Whenever the RTIP/RRING input pins are receiving a positive-polarity pulse
within the incoming DS3, E3 or STS-1 line signal, this input pin will be pulsed to
a higher voltage than its corresponding RRING_n input pin.
Conversely, whenever the RTIP/RRING input pins are receiving a negative-
polarity pulse within the incoming DS3, E3 or STS-1 line signal, this input pin
will be pulsed to a lower voltage than its corresponding RRING_n input pin.

These input pins along with the corresponding RTIP_n input pin function as the
Receive DS3/E3/STS-1 Line input signal for a given channel of the XRT73R12.
Connect this signal and the corresponding RTIP_n input signal to a 1:1 trans-
former. (See Figure 6)
Whenever the RTIP/RRING input pins are receiving a positive-polarity pulse
within the incoming DS3, E3 or STS-1 line signal, then this input pin will be
pulsed to a lower voltage than its corresponding RTIP_n input pin.
Conversely, whenever the RTIP/RRING input pins are receiving a negative-
polarity pulse within the incoming DS3, E3 or STS-1 line signal, then this input
pin will be pulsed to a higher voltage than its corresponding RTIP_n input pin.
