This may be a dumb question, but does anyone know what kind of cable to use to connect directly between two WIC-T1 cards, each one installed in an 1841? I have this configuration in the test lab for doing practice for the CCNA, but can't figure out what cable to use.
Can I use two cables - a RS232 DCE and DTE and just connect them, or will that make the pinouts incorrect?
Thanks in advance,
For a serial connectors (a straight-up WIC-1T), a DCE-DTE cable back-to-back works fine. You can also pick up a DCE-DTE back-to-back cable in eBay for a few dollars.
If you have RJ45-style connectors (WIC-1TDSU), then you'd use a T1 crossover cable (1&2-->4&5)
If you have one serial jack and one rj45 jacks, then connect a CSU/DSU to the serial port and run a crossover cable between the CSU/DSU and the RJ45 jack of the other router.
