Hello again,

A short question about Cellular Phones:

Let's say I have a 666 channel cell phone, and am in a system that
uses all 832 channels.

I start a call in Cell Site "A", on channel 555. I then drive to
site "B", and am switched to a new channel.

My question is: How does the new site, "B", know that I only have
                a 666 channel phone? Or does it know? Will it
                know not to connect me to channel 821, or will
                it try to connect me to 821, see that I don't
                responsd, and then try a lower, below-666 channel?

                Also, do cell systems leave space in the below-666
                range for phones that don't have 832 channel
                capabilities? IE, if a most of the below-666 channels
                are used, will it reserve some for callers that can't
                go above 666 so that if they come into the area they
                won't be cut off?

Well, thanks in advance for any info,

-Doug
