G.SHDSL Back-to-Back with 3700 and 2600

Hi

I'm want to configure 3700 and 2600, both with G.SHDSL wics installed,
to run a link over an EPS 9 circuit is this possible and what
configuration do I need on each of the routers.

Thanks

Rich

Hi Thomas,

Have tried that smaple config before but it does not work the line
does no even come up. The other problem is I no nothing about ATM why
is there a PVC 0/35 then PVC 8/35 also do you have to have a dialer
interface can't the ATM interface's just communicate without this

Thanks

Rich

 

The sample config does not seem to work do I need special cables or
are straight through RJ11 OK

Rich

 

Straight-through RJ11s should be fine.

I have a back-to-back 828 G.SHDSL configuration working based on the
sample config; though I think I removed the aal5snap encapsulated pvc (pvc
0/35). I did notice that the link can take up to several minutes to
establish (don't know if this is a 'feature' or not).

Cheers,

Matt

 

You will need acrossover cable.

I did find the pinouts for these ports the other day but can't
find them now.

 

Huh? How can you cross over a single pair of wire?

 

OK. I don't understand this much at all. (Still maybe I'll
learn something.)

How not?
If I cross the single pair of wires connected to
my car battery the car will not work and may in fact be
permanently damaged.

If I cross the single pair of wires on the connection to my
co-ax ethernet cable I suspect that my station would not work.
(I do know a little about this - baseband - signalling)

On the other hand if I cross the single pair or wires
connecting my bedside lamp to the mains it will still work.

If I cross the single pair of wires to my 1950 telephone
I suspect that it will still work. I guess that a modern
phone is the same and I suppose that a DSL line should not
be sensitive either.


Pinout for Cisco DSL ports:

As you can see the pins are differentiated by name (Tip - Ring)
if the polarity did not ever matter would anyone bother?

** Anyway, are you saying that a crossover cable is not needed
in this case? **

Thanks.

 

So what does the following mean taken from this link

The twisted-pair straight-through cable, for customer premises
equipment (CPE) applications, is supplied. The Y-cable, for central
office (CO) and 4-wire patch panel applications, is not supplied.
