Can you have collisions on a serial link? Thanks again.

Howard,
Does is it really matter if it is BSC or SDLC multidrop network. In an IBM
SDLC network you are dealing with Master/SLave design so you will never get
collisions becuase the Master controlls the transmission time
Most are full duplex, so in those cases, no you shouldn't..

This isn't an actual answer to your question about BSC and SDLC, which
Howard can do, but for all of you wondering about this issue, I recommend
chapter 3 of Tannenbaum, Computer Networks.
He goes into lots of interesting details about how to allocate a single
broadcast channel among

A serial link, is not a shared media.
Serial link is used for point to point connection = no collision
U can have collision if Tx is connected on Tx on the other side of the
cable, but if the cable and interfaces (X21, V24 ...) are good, there's no
collision.

I'm in general agreement, but be aware that you might run into IBM
BSC
I think this is actually more of a CCNP troubleshooting question. Think
about the type of media you're dealing with. Collisions happen on media
that allow multiple devices to speak at the same time. If the media or
topology does not allow multiple access then you cannot have
collisions.

Tis why I said most and shouldn't :) I expected the longtime lurkers to
come back with a couple that weren't full duplex.

I agree with you.
Serial link is not always full duplex. It depends of the relation between
the two entities : primary/secondary (Normal mode : SDLC - SNRM frame) or
Balance mode (LAPB - SABM frame).

When I first started at the bank as a teller, we were running 9600 bps
multidrop lines. but, luckily for me, I was blissfully unaware of
anything related to networking at the time, so I didn't notice. ;-)
By the time I started in the department we had upgraded to 56k frame
relay with Motorola
