Also, use only cable labelled RG6. And, check all connections to make sure they are not loose or poorly

terminated.

It will give a lot of practical info about LAN wiring. For cabling hardware, check out MicroWarehouse at

tab. Scroll down to 'System tools', select it by clicking on it, and click

'Details' button. Select 'NetWatcher' from the menu, and OK your way out.

DSL Modem – Replacing PacBell’s – Watch for VPI/VCI

Note: my PacBell/SBC Westell Wirespeed has VPI=0 and VCI=35.

He used to have a Cayman 3220H and recently tried hooking up in his home an Efficient Networks 5360

that was recently installed in his office. The red lights turned to green after a while, but try as he might, he

couldn't get an internet connection, even though he used the exact same settings that were used by the

Cayman. Trying to reach someone at Pacbell is going to require a 30-minute hold time only to be asked 10

times what operating system he's using. I'm wondering if maybe the MAC address (I'm pretty sure DSL

modems have one) is hard coded at the CO to prevent illicit access, which would explain why he's not

getting through. Anyone know for sure?

Although your DSL Bridge's Ethernet interface does have a MAC address, I doubt that it has anything to do

with the problems you're experiencing.

You probably need to set the VPI/VCI settings to what they were with the Cayman. You should be able to

configure this, but I'm not familiar with how to do that with the Efficient Networks Bridge. I also don't

know what the settings ought to be for your service. A helpful ISP like Sonic.net would tell you, but good

luck dragging that info out of SBC.

Your DSL modem talks to the ISP using ATM packets over a PVC. The two numbers are the VPI/VCI

which are the address of your PVC at the ISP's end, similar in concept to an IP address and port number.

Here are some definitions from a document I don't have a current link to:

virtual circuit

Logical circuit created to ensure reliable communication between two network devices. A virtual circuit is

defined by a VPI/VCI pair, and can be either permanent (PVC) or switched (SVC). Virtual circuits are used

in Frame Relay and X.25. In ATM, a virtual circuit is called a virtual channel. Sometimes abbreviated VC.
