Re: Another CCIE Written Question [7:17050]

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 competi

Re: Another CCIE Written Question [7:17050]

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.. > >Brian "So

Re: Another CCIE Written Question [7:17050]

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 F

Re: Another CCIE Written Question [7:17050]

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). -- Stephane LITKOWSKI Student in a french computer science school EPITA Telecom & Network spe

Tis why I said most and shouldn't :) I expected the longtime lurkers to come back with a couple that weren't full duplex. Brian "Sonic" Whalen Success = Preparation + Opportunity On Thu, 23 Aug 2001, Howard C. Berkowitz wrote: > >Most are full duplex, so in those cases, no you shouldn't.. > >

Re: Another CCIE Written Question [7:17050]

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. On mos

Re: Another CCIE Written Question [7:17050]

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. -- Stephane LITKOWSKI Student in a
