which you plugged a different computer into your cable modem and it couldn’t
access your connection, please proceed to the Troubleshooting section T2 entitled
“How do I Find Out my PC Network Information” before plugging in your MTA,
and then, section T7, “My ISP Checks MAC Addresses and I Haven’t Set Up the
Custom MAC for the MTA.” If you skip these very short exercises, a problem may
later require you to spend many minutes on the phone with your Internet Service
Provider to straighten things out. If you haven’t previously experienced that
situation, we recommend the following tip:
Tip: Cable Modem users should turn the power off the cable
modem (unplugging the cable modem’s power adapter if
necessary) for a minute before connecting and turning on the
MTA for the first time. This may resolve problems for cable
service providers who track MAC addresses on a per session
basis.
Connectors and Switches
All the connectors are of different shapes or sizes and are clearly labeled to make it
difficult to place the wrong cable in the wrong jack.
Tip: WAN stands for Wide Area Network. The cable between your
broadband modem and the MTA goes into this plug.
In the following chapter you'll find an illustration of the back of the MTA; the
following describes each plug or switch:
