What is E2-1, S3-1, T0-1 in a Cisco router?

[JEDI]

In class, I learned my Cisco on a 2500 series router. That router had E0, E1, S0, S1, Console, and Aux ports.

I'm now looking at a diagram of a network w/Cisco 7000 router. That router has E2-0, E2-1, E2-2, S3-0, S3-1, S3-2, T0-0, T0-1, T0-2, T0-3, T1-0.

What is a E2/1, S3/0, T0/1, etc?

The 7000 series has slots. The E in your example is a 4 port Ethernet card, in slot 2. The S is a 3 port serial card, and the T is Tokenring I think.

Man, I'm slow. Blasted phone!:disgust:

Yeah, that covers it pretty well!
For some dumb reason i was thinking the European format. Like, E1 instead of T1 etc etc.
Man, sometimes my brain is thinking the right stuff in relation tot he wrong thing at hand.
I hate it when it does that. :frown:

ok..here's another question.

On the schematic, it goes cisco 7000-> csu/dsu-> t1 circuit-> paradyne-> cisco 7000.

What's a paradyne box?

It's another csu/dsu, paradyne is just the name. Here is a pic of one.
