Description
Ethernet Port
RJ45 port that supports 10/100Mbps connections and provides
Power over Ethernet (PoE) power to compliant devices.
Antenna Connector
One of the three connectors for the three 5GHz antennas supplied
with the CMAP. The other two connectors are located on the other
side of the unit (see
DC Connector
In addition to the power supplied by the coaxial cable from the
CMTS, the CMAP may also be DC powered.
Shorting pins 3 and 4 in the DC power connector using an electrical
shunt will reset the CMAP to factory default settings. For more
information, refer to
Coaxial Cable
Connector A
Provides a 9 dB lower sample of the downstream RF signal as seen
by the modem electronics. Therefore, the CATV tap should be
selected to provide a measured downstream signal level on this
port, which is approximately 12 to 20 dBmV in the channel being
used.
Coaxial Cable
Connector B
Connects to the cable modem termination system (CMTS) at the
headend using a tap on the plant and it provides AC power to the
CMAP. AC power is supplied via Power Over Cable (POC). For
