Hi Everyone,
First time placing a post, I hope someday to share and
contribute to the group like all of you.

BRI interfaces. Each BRI to be connected to a remote site. My first task
was to get BRI0 up

strange problems. My most current problem is that DTR on the TA keeps going

Tony,
If you have an ISDN modem, it's pretty much the same thing as an analog
modem (from the routers perspective). If you are trying to plug the ISDN

In the 2503 router you have two options to make it dial put a dialer-string

This does make me wonder if any atm's use ATM.
Joking aside, many money machines use an interesting ATM variant:
At the bank that where I worked, we used ATM at the primary/secondary

The telco did the ATM FR mapping in thier switches. We also had ISDN as

It appears that you could use a router with three or more serial interfaces.
Also another ISDN BRI interface. A 2522 would be a good choice or consider a
2523 that has a Token Ring port. Next router after that could be a 2513.
Can you afford the 2522 and keep the
Ill trade you the emulator for a 2525 with modules, or a 4000m with modules
either way.

Hi,
I have two ISDN BRI S/T interface routers. Any methods connect them
together like connect serial port together at home (for Lab Test)?
Thanks!

Hello group,
I am studying for the CIT exam and I have a question
regarding multiple isdn devices sharing a single bri
connection. Assuming a router and ISDN phone sharing a
the same s/t bus, how should I Identify each device so
that when a phone comes in the router does not
respond. Assume that
Hi all,
I have a core router connected to 2 other regional
routers, with only 1 ISDN backup. The config is as
below:
Unfortunately these 2 regional routers down at the
same time and both keep trying to dial up the ISDN
line. The result is both of them unable to get the
connection. What should I

Is there anything that I will be unable to do [that is relevant to preparing
for the CCIE lab] with an ISDN simulator (versus having actual ISDN service
with my local phone company).
Thanks
Derrick,
You can not simulate an ISDN connection without some type of ISDN
switch...whether it be the telco ISDN switch, or an ISDN simulator, you need
something to act as the CO. You could purchase an ISDN line from the
telephone company, and split the B-channels. That would probably be the
No
Every effort has been made to try to simulate ISDN without a simulator, but
todate no one has come up with a fix. You need a simulator.

Can you copy the relevant portions of the configs to the list? With
something this odd it would help to look at the configs.

Michael,
I've seen this, and problem was SS7 configuration between telco
switches. Basically, they configured isdn switches so that isdn
calls can be made in only one direction.
Have you tried to connect plain phones into NT1 (in case that
NT1 supports them) and to call other location
I had a problem similar to this in Canada with an ISDN circuit. Try placing
a 9 in from of the dial string. Like office phones when you need to grab an
outside line.
My dial strings looked like 913035551212. The 9 to grab an outside line and
then the full dial string with the 1 prefix for long
Thanks, Sasa, I'll try this one.

Jim Is probably right:
You are dialing wrong phone number. It has an unknown format to the isdn
switch.

I have seen similar problems with an ISP. What are you dialing into? Another
ISDN line, PRI, or a T1?
I'm going to hazard a guess that you needed to put a 1 in front in order to
dial long distance. Are you sure that whatever type of circuit you are
dialing into can accept ISDN calls?

Guys,
As one of you suggested there was no long distance setup for the line.
Thank you for your help.
