OT: Cable Lengths [7:74776]
I have a question regarding the max length for a 100BaseT cable. Granted I haven't done a wealth of research on this so feel free to point me to google if the answer is mind numbingly simple, which it probably is I have always understood the 100M limitation on 10BaseT ethernet cable to be attributable to the time it would take a collision signal - assuming you are running at half duplex - to be returned in time to prevent the next packet from being sent. In other words any longer than 100M and the sending station would not get the message in time that there had been a collision and thus continue sending packets instead of backing off. I have heard attenuation mentioned, but not as the real reason for the distance limit. My question is given that many stations are running 100 full duplex these days - thus removing the collision concerns - does this effectively change the maximum distance for cable runs? Or is attenuation truly a factor in anything over 100M? In general I am referring to standard Cat5 cabling Just curious...

Re: Cable Lengths [7:74776]
looking at it practically, you can run cable at 150 m and still make it work. but the question is, will it meet the reference crieteria. there are a lot of things to be looked at here of which an important factor is attentuation. -Nakul [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I have a question regarding the max length for a 100BaseT cable.

I've seen situations where the legal length has been nearly doubled on full duplex connections without much apparent trouble. I don't know if I'd trust a Windoze box in this kind of configuration, but routers, unix hosts, etc, don't seem to mind too much.

RE: OT: Cable Lengths [7:74776]
The diameter of a 10Mbps Ethernet collision domain is much bigger than 100m (you can calculate it from the smallest allowed frame size, the transmission speed, and the signal propagation speed), so that limit is most definitely not based on collisions.

Windows *sucks*. I've seen it act stupid in lots of situations where a FreeBSD laptop with the exact same configuration works just fine.

EM Back-to-Back Cable [7:73954]
Hello I want to connect EM ports on Cisco routers back-to-back, but wandering how it can be achieved. Seems Type 2 and 5 of EM are symmetrical, so theorically it seems possible, but pratically is it true? If it is possible what kind of cable should I use ? Some kind of roll-over or cross-over cable might be needed, but what kind of pin connections ?

RE: Access server 2511 Cable Tricks [7:73671]
Regular RJ interfaces on a 2511RJ use a rollover cable - just like the console cable that comes with routers. They shipped green cables with the routers - I guess to make it easy to trace them.

RE: cisco back to back cable [7:71992]
One more possible issue. Recently I installed a back-to-back cable in my lab. On the DCE end I verified the cable: sh controllers s 0 - It showed DCE. I then configured the interface; config t int s0 clock rate 130 ip address no shut end The router returned an error message that seemed to indicate that it thought there wasn't a DCE cable on that interface. Now interface s1 was configured for a DCE cable and it worked just fine. OK, reload the router. no change Power off the router Now it works.

I'm thinking that even mentioning a straight through cable when connecting two T1 interfaces together is a good way to confuse the person asking the question.

RJ-45 and RJ-48 as used for a T1 circuit are effectively the same. As long as the distance is not too great from the demarc to the router, Cat 5 UTP cable can be used. For long distances, shielded UTP is called for. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Thomas N Sent: Thursday, June 12, 2003 1:39 PM To: [EMAIL PROTECTED] Subject: RJ48-RJ48 cable [7:70596] Hi All, I am wondering what is the difference between the RJ48 and RJ45 connector/cable?

An RJ48 connector is basically an RJ45 connector with only pins 1,2,4 and 5 terminated for a T-1. I don't recall if there are any other differences. I think just about any short, straight-thru, flat satin cable will work just fine. Many of them have ferrite rings on them for noise reduction, I believe. In a pinch a straight thru Cat 5 cable would work just fine. There may be some technical reasons why you wouldn't want to use twisted pair cable, but I don't know about them. I try not to use UTP unless I have to, though. Someone else here is bound to have more technical details and they can fill in what I've neglected to mention or correct any mistakes I made.

Thomas, You can use a straight-through CAT5 or CAT3 patch cable. The difference is in the meaning of the pins.

Re: creating console cable for cs11152 [7:64368]
I see what you're after now. yes you can do this. the adapters are the trick here. cisco will use a rollover cable to essentially pair wire 1 on one end to wire 8 on the other end (2 to 7, 3 to 6, etc...). in theory what this does is reverses the the Tx and the Rx and the other corresponding wires for flow control and modem control. the adapter then comes in for when you plug it in to the interface. for example if I have a eia-232 configuration, then my adapter will have to be wired correctly to place the correct pin from the adapter to the correct wire on the rollover cable. same thing can be said if I have a v.35 cable, I need to have the adapter connect the Tx pin to the Tx wire of the cable. this is why cisco advertises their db-60 interface as being 5-in-1, because depending on how the pins match the wire, they have 5 different specifications possible(one being eia-232) now sticking to eia-232, the specification calls for 8 pins, which is perfect for 8-wire cable and thus why cisco uses it for all their modular console ports. now the adapters come into play. the adapters can serve one of two purposes, 1) straight-through or 2)rollover. if the cable you use is a rollover, well then the wires have already turned the Tx into a Rx wire and thus your adapter needs to be straight-through to accomplish having the ends stay Tx to Rx. if the cable you use is straight, well then the wires are Tx to Tx and thus you'll need an adapter to change the Tx to the Rx. now heres the kicker and the reason I suspect you're having problems. this whole discussion of Tx going to a Rx end-to-end depends on the fact that the console port of a router (or a CSS) is a DTE and your PC serial port is a DTE and thus needs to be rolled-over. on the other hand some older cisco equipment had their console ports configured as DCEs, which might very well be you case. so what to do? put the adapter onto your computers serial port, plug the cisco rollover cable into it and then right into the console port of your css. if it works you're done, if not get a standard straight-through cat5 cable to use instead of the cisco rollover, that one will then work.

When its time to stop for bad weather they will tie bouys to the cable and sled chains and then leave and come back later.

Here are the 2 devices that will do what you are looking for. But what these devices do is load balance seesions outbound from the local lan. So if you have like 5 pc's on the lan and 2 pc's started internet explorer at the same time one pc will go out over one connection the other pc will go out over the 2nd connection.

It seems like you could only load balance sessions and not packets, which would be pretty useless in almost all circumstances. Might I instead suggest that you simply upgrade your bandwidth (simple, easy way) or use another hack like a download manager tool (about as tricky as a Cable/DSL load-balancer)? http://download.com.com/3150-2071-0.html?tag=stbc.gp -dre Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=59307t=59306 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Power Cable [7:58614]
Sounds like a standard IEC kettle lead to me. At least here in the UK, thats what they're for, electric kettles. IIRC these plugs are used for temperature-resistant leads, and the notch allows you to use a temperature-resistant lead in any application, but to disallow the incorrect lead in your kettle or other hot object. This may be an indication that your 7000 is going to suck some serious power 8^) In the UK you can get one of these in the local electical store, YMMV. rgds Marc NetEng wrote: I bought a 7000 router off of ebay.

The cable you mentioned should work. The AC power supplies on a 7000 and a 7507 are the same. (Unless changed recently.) FWIW They shipped the same cord with Cat5K Power Supplies even though there is no notch on the PS receptacle end. Any chance that they sent you a cable for a 7513?

RE: Cisco DTE/DCE Cable [7:58103]
Maybe you don't need to change your cable at all. DCE vs DTE is significant at layer 1 for clocking issues. There is also DCE DTE at layer 2 for Frame Relay purposes. The layer 1 DCE does not have to be on the same box as the layer 2 DCE.

So far, so good. I managed to get the MIB file CISCO-DOCS-REMOTE-QUERY-MIB.my and i saw that it can be used since version 12.1(2)T1, or this is what i understood from 'added 12.1(2)T1'. Another problem is that the software version on my uBR is 12.0(10)SC - early deployment release software (i assume i need an upgrade :))). Now. I have a few linux boxes and i run MRTG.

I assume there has to be a way to solve this problem without going to each and every customer and reset the cable modem.. When a modem looses the frequency it was acquired on, it starts scanning for another one. At first, it takes steps of (I believe) 3 MHz. So it doesn't take a very long time to go through the whole spectrum. But when it still can't find a frequency, it starts scanning in steps of 125 kHz. And then it can take an awfull lot of time for the modem to acquire again. When you reboot the modem, it will start looking for the frequency it was last acquired on, before it starts scanning. So that's why a modem comes online immediately after a power cycle. Maybe you're just not waiting long enough for the modem to re-acquire again? It would be interesting to see what the modem is doing, so maybe you can get a friendly customer to look at that via the web browser? (If that's possible, as I don't know the make of the modem) At least then you know if the modem is scanning or just locked up. Hope that helps.

Talk to you later. ;-) Priscilla What this means is that in this RJ45 splitter situation, the two senders don't know when the other one is sending. The hub isn't putting it back onto their receive wires. They can still do ordinary collision detection if some other station in the collision domain sends while they are sending, but they can't hear each other. The result must be severly errored frames that the hub merrily propagates to all ports! That's very bad. I think the only reason it works is because the recipient NICs drop the garbage and upper layers at the sender retransmit. Also, it works because the stations aren't actually sending at the same time a lot of the time. Now I wonder why the splitter didn't work on the switch? Did the switch diable the port due to the high number of CRC-errored frames or did it recognize some other problem?? Was there a link light? Just for old times sake, I plugged that splitter back into a wall jack and tried it with our switch (unfortunately, that sits where I couldn't easily get to it, so I can't answer the link light question at the moment). Sure enough, I got that cable unplugged popup on both machines. I'm guessing that your'e right about the switch locking out the port. Our IS folks were gone for the evening, so I couldn't ask them if they have the ports locked down to a single MAC, or anything along those lines. It might simply be that having two NICs on a switch port causes impedence issues that didn't affect a hub in quite the same way?

The TX/RX loopback is inside the NIC, from what I understand. I don't think the senders see each other's transmissions even though their TX wires end up being the same wire past the splitter. But I always try to work above the physical layer and may be missing something. Well, it's time to move on.

Re: can cable spliter create more switch port? [7:55667]
I will volunteer a similar cable I have seen a long time ago. Only 2 pairs are required for connection. I have seen an adaptor where two circuits were wired to provide two ports over one cable where there wasn't enough wire strung. At the patch panel two cables came out of one port into two switch ports. At the distant end another adaptor broke out to two PCs. For 10BaseT it worked OK.

can cable spliter create more switch port? [7:55667]
Hi.. I have a friend staying in the hostel room which has a wall port (RJ45) link to the internet. As there are two persons (two PC) staying in that room. So they bought a cable splitter. (one side with one female RJ45 jack and another side with two female RJ45 jack). So that two PCs can connect to internet at the same time, However, I did the same thing to my switch port to make it one switch port to two ports but my PCs that connected to the two ports can't connect to the network at all. Did I did anything wrong? Bought the wrong cable splitter? Or my friend's campus end back is different from mine?

A UTP cable has eight wires (one day with we will use them all). An ethernet connection uses 4 wires (pins 1,2,3,6) at the moment CDDI (1,2,7,8 I think). All a cable splitter does is it saves you running two seperate cables to a destination, it uses the spare 4 wires and makes an extra cable point. Got nothing to do with electronics.
