Just out of curiosity, How might I log into my DSL box and verify the

Another thing has occurred to me. When I had the old Netopia box, to
avoid paying for another line extension to the phone company, I ran a
15' phone cord, which came with the Netopia, from the jack to the
DSL box. The phone cord that came with the ZyEXL is maybe 4' tops.
So, rather then continuing using the old Netopia phone cord... I am
biting the bullet and putting another extension close to my DSL
modem. I'm not going to tap into the original extension the
distance of phone wire would be doubled from the NID (spelling?). I'm
going to run the wire from the NID or is it NAD and terminate
with an extension by the box. I was wondering, instead of just using the
RED and GREEN cond,
connected to the RED and GREEN terminals, would it provide more
conduction to add the yellow and black cond. too? Or, would that not
work or cause a problem sending the Verizon gods breathing fire upon
my humble self?

Either way a shorter distance from the NID to the DSL box can't hurt.


There can be 18,000 feet of wire, between you and the CO. Is another
25 feet going to make a difference ?

I'm a little curious about the two ADSL modem devices.

For example, in this thread, they mention PPPOE coming from the
Netopia Cayman 3300 series.

http://www.dslreports.com/forum/remark,9643208

I've had the same DSL setup for a number of years, and the modem I've
got, still talks PPPOE. To use the modem with a single PC, I need a
software solution in place, that understands PPPOE when it is seen
on the Ethernet cable coming from the modem.

Soon after I got the ADSL modem, and saw what a piece of crap that
kind of software solution was, I got a router. The router had PPPOE
termination as a feature (virtually all of them do that now). The
LAN side of the router talks "ordinary" Ethernet, while the cable
running between the router and the ADSL modem, is PPPOE (point to
point protocol over Ethernet).

It is possible the networking setup offered by the new modem, is
different. The ZyXEL P-660, if a combined modem/router, has no reason
to use PPPOE on the Ethernet, since it has the "router" in the name. It
has to terminate the PPPOE protocol, before it can "route" anything.

That means, you cannot slap the ZyXEL P-660 in place of the Cayman,
without at least thinking about whether the situation has changed.

Just for reference, this is my (old-fashioned) ADSL setup, with
PPPOE protocol as the only output option of the ADSL_modem.
If a newer modem was used, there would no longer be PPPOE.

The filter passes low frequencies to the phone (like 4KHz or below).
A filter is used, before each telephone. The full bandwidth is
available to the ADSL, since there is no filter in that path.

In this picture, the red color is the frequencies the analog phone
uses. The green and blue, shows the range of frequencies the ADSL
modem uses.

Yes Paul, the ZyXEL P-660 has a built in router, but I believe with just one
Ethernet port. You can hook a "dumb" 4-port Ethernet bridge to it and hook
up more than one PC, provided it is not in the bridge mode and the DHCP
section of the box has not been locked by the ISP to provide only one IP
address.

Some ISP's still lock the DHCP to only one address in order to force users,
who don't buy an external router, to pay extra to hook up more than one
computer. Then they raise the DHCP one level for each PC they were able to
extort the user into paying for.

Some ISP's still lock the configuration screens from a users view by loading
proprietary software into the box and installing a second (management) level
password. In that case the user level password only lets you view what that
ISP wants you to see. In that case your only choice is to live with the
situation or in the USA purchase a DSL modem from someone other than the ISP
and send them their box back. They usually try to retaliate by refusing
support or claiming all problems with the connection is caused by "your"
box.

When the P-660 is in the bridge mode the built in router is disabled and
the PPoE login functions have to be done by the PC or a router between the
DSL box and the PC.

When it is (not) in the bridge mode the internal router of the P-660 DSL box
sends the PPoE login for you but you do have to configure the box with the
Username and Password which it stores for use when needed.

As Paul indicated, you can't have the DSL modem sending the PPoE login info
and the PC. It's either one or the other depending if the DSL modem is set
for bridge or not.
