8.6 RJ-45 Ethernet M&C Connector Pin-Outs
The 10/100BaseT Ethernet M&C connection utilizes a RJ-45 connector, as shown in the following
figure, which also depicts the arrangement of the pins, looking into the connector. There are two
Ethernet connectors, one for the demodulator only (P1 on the AMT-70 and J10 on the AMT-73L)
and one for the modulator and demodulator (P6 on the AMT-70 and J9 on the AMT-73L).
Use of the demodulator only Ethernet port is intended for factory testing and updating demodulator
software changes.
communications with the modem during normal usage.
