The 2503 doesn't have an DSL capabilities so you won't be able to
connect it up to your ADSL connection, you'd need to get a standard ADSL
router for that. However if you really wanted to play around you could
get another one and connect it up as...

ADSL <<>> ADSL Router <<Ethernet>> 2503 <<Serial>> 2503 <<Ethernet>>
Your Computer

...and have a different subnet between each one, and then have your
internet traffic routing across it all.

Hi Terry,

Thanks for your reply,

Just to get things a little more clear,
I will be connecting my adsl router to 2503 on its ethernet port and
from the serial port on 2503 i will connect a cable to my NIc on my
pc.
This means i need a serial to rj45 cable. Do you what is the cable
called, or i just ask for serial to rj45 cable.

Thanks for your Help

No, you can't connect the serial to the ethernet.

This is what I've done on occasion, and it may help. You want to use an
ADSL router, preferably through a crossover cable to your 2503. If
memory serves me, you need a transceiver on the 2503. You could still
connect your computer to the router via another crossover, unless you
have a spare place on the 2503 for a second transceiver. Centrecom and
others make them, they are relatively inexpensive. You also need a
rollover cable which is serial-RJ45 to go from the serial to the Console
port of the router. I am going to suggest the following, which may save
you some energy as it did me. Go get an adapter which is usb-serial. If
you search carefully, you can pay maybe $8.00 and shipping on Ebay. If I
recall, Cables-R-Us is one vendor. I like this kind of adapter because I
can move it around to my other devices. If you expand your network, I
recommend 3550s or 2620s, though I know that's subject to debate. I find
the 2620 a much better router for practice, even though I've been at it
only since August, and paid money out the @$$ for my entire set up. If
you are spending money on equipment, do yourself a big favor. Get thee
to a store and get the CCNA Command Quick Reference, which I have found
an indispensable asset! Just the cabling guide alone was worth the price
for me!

Best Wishes,
David
