Greetings,

What is the best way to busy a phone line?  I have a bank of modems
and from time to time I need to pull one from the pool.  Some modems
have a "busy out" swtich.  My modems do not have a switch.  Pulling a
modem causes the hunt to stop at modem I pulled, giving the caller a
"no one is home" type ring.  I have heard that putting a resistor
accross the wire is enough to hold it off hook.  If memory serves it
was a 1000ohm resistor.  I have hesitated to do this without trying to
learn more.  What effect does this have on the switch?  Does the
effect varry from phone switch to phone switch?

Thanks.
