Re: serial interface down/down or up/down [7:47101]

[Roy Bender]

Hi Everyone, I am new to this group and I just passed my CCIE written and am
looking forward to participating.

I have done a lot of lease line installs the last couple of years, and I
have worked with EIA-530, V.35, G.703, EIA-232 etc...Most of these installs
required me to go through an additional pieces of equipment like a hardware
encryption unit or an additional set of CSU/DSU’s to extend the circuit
while maintaining the carriers Demarc point. Anyway, I have been required to
make numerous cables to make things talk. And during troubleshooting/testing
with a breakout box I discovered that the only signal required to bring the
serial port up was a high on DCD/CD with all other leads open. Just
something to think on. Cheers
