:
The Receive Section of a given channel will declare the LOL condition
anytime the frequency of the Recovered Clock (RCLK) signal differs
from that of the E3CLK input clock signal (if the channel is operating in
the E3 Mode), the DS3CLK input clock signal (if the channel is
operating in the DS3 Mode) the STS-1CLK input clock signal (if the
channel is operating in the STS-1 Mode), or that clock signal which is
derived from the SFM Clock Synthesizer block (if the chip is operating
in the Single-Frequency Mode) by 0.5% (or 5000ppm) or more.

Receive Positive Data Output - Receive Data Output - Channel 2:
The function of these output pins depends upon whether the channel/device
has been configured to operate in the Single-Rail or Dual-Rail Mode.
Dual-Rail Mode - Receive Positive Polarity Data Output
If the channel/device has been configured to operate in the Dual-Rail Mode,
then all positive-polarity data will be output via this output pin. The negative-
polarity data will be output via the corresponding RNEG_n output pin. In other
words, the Receive Section of the corresponding Channel will pulse this output
pin "High" for one period of RCLK_n anytime it receives a positive-polarity pulse
via the RTIP/RRING input pins.
The data that is output via this pin is updated upon a user-selectable edge of the
RCLK_n output clock signal.
Single-Rail Mode - Receive Data Output
If the channel/device has been configured to operate in the Single-Rail Mode,
then all Receive (or Recovered) data will be output via this output pin.
The data that is output via this pin is updated upon a user-selectable edge of the
RCLK_n output clock signal.
