thanks
Hello Everyone, I'll be leaving the list now. Maybe be back when I am more motivated. Just note to everyone that while I did learn a lot here, the most valuable thing I learned was to look it up myself before asking for help. Good Luck and Don't forget the blueberries.

pps to bps
Hello Everyone, Kinda tricky question about ethernet. Is the correct conversion; PPS * 704 = BPS or PPS * 672 = BPS 64 byte frame including CRC + 8bytes [preamble] + 20bytes [interframe] = 84 bytes 84 * 8 = 672 672 - 704 = 32 bits = 4 bytes. 704 popped into my head and I can't figure out why. Am I forgetting 4 bytes or am I remembering what the blueberries told me?

RE: Hub-to-Switch connection problem
The problem you are facing isn't osi layers. Its pinouts. The pinouts for 10/100 ethernet are 1,2,3,and 6. 1 and 2 are tx and 3 and 6 are rx on some devices such as switches, hubs, routers. and 3 and 6 are tx on other devices, like nics. you use a crossover cable to connect tx to rx. tell me if this helps. larry p.s. i might be backwards but the idea is the same. -Original Message- From: analogkid01 [mailto:[EMAIL PROTECTED]] Sent: Friday, December 01, 2000 4:31 AM To: cisco Cc: analogkid01 Subject: Hub-to-Switch connection problem Okay gang, I had an interesting and annoying situation yesterday morning, and I'd like to see if anyone else has had an experience like this: My client was installing an older BayStack 301 switch into their existing network, which consisted of a Bay Access Node router, as well as four stacked SynOptics LattisHubs. The router was experiencing excessive collisions, hence the installation of the switch. So we installed the switch and cabled the router to it, moved all the "power users" directly onto the switch, and left the other users attached to the hub. We attached the hub to the switch via a straight-through cable. The users who were directly connected to the switch had no problem accessing the network and Internet. The users on the hub were dead in the water. We tried swapping out the cable between the hub and switch, tried plugging either end into different ports, tried flipping the MDI/MDI-X switch, and nothing worked. The only thing that *did* work was using a *crossover* cable between the hub and the switch. Now, the rule (which I gleaned from this newsgroup, btw) is that when you're connecting devices at different OSI layers, you use a straight-through - e.g. PC to hub, PC to switch, switch to router, hub to switch - that's all straight-through. You use a crossover when you're connecting devices at the same OSI layer - router to router, switch to switch, hub to hub, PC to PC. In the situation yesterday, a straight-through seemed logical, as we were trying to connect a hub to a switch. Am I wrong here? Why did the crossover work? Thanks, BJ P.S. sorry for the Bay-centric example...I'm trying to get them to change that. ;-) _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
t1/e1
Hey everyone, I've been looking for a part # but can't seem to find it.. So in the 2600 series, there is a wic avail. that is t1 w/ csu/dsu built in. This allows you simply to make a rj-45 t1 cross-over cable and connect them. Also pretty nice, is they use slarp to config themselves.. Well, I can't seem to find an E1 version of this card. URL's and documentation would be excellent response.

RE: t1/e1
just to clarify with everyone, i am looking for the E1 version of the wic-1dsu thanks larry -Original Message- From: jonw [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 24, 2000 8:59 FatLarr To: laveritt; cisco Cc: jonw Subject: RE: t1/e1 I believe that the part number is WIC-1DSU-T1. But try this link and look under useful tools, you will find a solution finder that will list the modules and their requirements. http://www.cisco.com/go/module Jon Wagner CCNA -Original Message- From: [EMAIL PROTECTED] [ mailto:[EMAIL PROTECTED]] Sent: Thursday, August 24, 2000 10:41 AM To: [EMAIL PROTECTED] Subject: t1/e1 Hey everyone, I've been looking for a part # but can't seem to find it..
