Connecting 2 routers

[Guest_imported]

I have 2 routers

A 1604 R w/ ISDN phone and BRI 0 u
A 2503 w/ 2 Serial, a BRI, and a Aux.

Is there a way to connect these two for a home lab with out using the ethernet connections. Like a cross over cable, or null modem to connect the BRI's, or is that not possible.

Thanks

I'm not aware that you can connect BRI ISDN back to back. there are several ISDN demo boxes available but they are not very cheap.

If you had to AUX ports, you can connect them back to back.. see

Two serial ports can go back to back with a DCE and DTE cable screwed together or a custom cable.

Two T1 cards can go back to back by making a loopback cable.. 1 to 5 and 2 to 4 on both ends. That flips the transmit and receive pairs.

But ISDN??? I'm out of ideas
