...nd it looks like prices on KVM head units have dropped a bit over the years. Some of the older units only worked with Windows, Internet Explorer and ActiveX. Others like the ATEN KH1516i supposedly use Java and are far better from a cross-platform point of view. I'm on the fence about the CAT5 cables over the more traditional style, it seems like the CAT5 cable system would give a lot more flexibility in dealing with USB vs PS/2 servers (or even serial only?). The bigger advantage with the CAT5 stuff seems to be fewer length limitations and less space used in the rack for the head u...

...find the median category. Trivial to do by hand, but I was wondering if there is a means to do it in R in an elegant way. The obvious medioan(vector) returns the median frequency for the binns, and that is not what I want. i.e,: freq cat1 1 cat2 10 cat3 100 cat4 1000 cat5 10000 I want it to return cat5, instead of cat3. Thanks a lot Martin

Is there any technical difference between a T1 cable and a cat5e patch cable as far as using them with Digium T1/E1 cards? Can PRI circuits terminating at a smart jack connect successfully to Digium cards using straight through CAT5e cables? If so, are they using all of the pins in the cable? Thanks in advance

We currently have a 15-phone system using Asterisk, a combination of analog phones/Grandstream HandyTone-286 and Grandstream BT101s, and 4 X100Ps connected to analog lines. The system works well except for the occasional echo problem. I have all the echo parameters configured, removed all the extra incoming analog lines except to the PBX, etc. following all the advice on the wiki and on the

...on tool I can use to replicate a real world PRI but without the telco line being installed. And secondly, can I have a scenario with 2 asterisk servers with digium e1 cards 'back to back' one configured as the network side and the other configured as the client side (can I just use a single cat5 straight through cable between them ?? and cant the Digium e1 cards operate ok in both modes?) Any advice would be greatly appreciated

What gives with the stupid stupid power system on the Polycom IP500 (I hope they changed it on the 501's). Anyway, does anyone know if you can get some type of joiner to connect two Cat5 cables together, and will this affect the call/signal quality because my Ethernet cable is longer than the dumb 11ft polycom supply (oh and their manual is the wrong about which end goes into the handset end...how bad is that).

...s cost and weigh more than triple what they do now. He told me that with the number of twists in the Cat 5 cable it would cancel out any interference, but he also stated that the effective length was calculated using a cable with less twists and subsequently 'less dense' and that if using a Cat5e cable you must factor that in. so if you use cat5e cable your are fine but you can't go as far. Regarding the Smart Jack it is mostly used as a location at the CPE where the Telco can loop and make sure that the problem is at your end. So your assumption is correct that you can plug anything...

...uments it like this: Pin: Signal: 1 Rx1 2 Rx2 4 Tx1 5 Tx2 (http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm - bottom of page) So my question about a "real" T1 cable isn't specifically about a crossover cable, although the principle will still apply. I was talking about using Cat5/5e 4-pair cable (*not* a pre-made Ethernet patch cable, just Cat5 cable in general) to carry a T1 signal between the NIU/SmartJack to the CPE. (I could crimp my own or buy them, depending upon my specific needs. For a short jump I'd probably just fabricate my own.) So the question is really...

Can't anyone stop self-promotion and tell the poor guy what he needs. A T1/E1 X-over cable using an RJ-45 (8-cond.) is pinned out as follows: 1 - 4 2 - 5 3 - NU 4 - 1 5 - 2 6 - NU 7 - NU 8 - NU NU = Not Used I have not in my experience seen any problems with using a Good Quality Cat5 vs. Cat 3 (telco standard) cable for X-connects. YMMV, but you should be fine. As far as the shielding goes, I use UTP cables and Connectors all the time and some of my X-connects run over 100 feet. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-...

I heard about some inexpensive security cameras which get their power through the same cat5 cable which delivers the data/pictures (which would simplify wiring tremendously). Does anyone know about these? Do they work with Linux, particularly CentOS? tnx 4 tips.

Hi, My set up is : Asterisk with B410P in NT mode <-------------cat5 straight cable ----------------> Another PBX in TE mode Is the 100 Ohm terminator you can find on B410P boards, necessary when connecting in NT mode to another PBX (set in TE mode) ?

...E of 10.1.1.150 from 00:40:63:e5:71:4f via eth0 (not found) Depending on the thin client, the MAC and the IP changes. Otherwise, the errors are all the same. The effect on the thin client end is that it doesn't get an IP, and so it doesn't boot. The usual remedy is to unplug/plug-in the cat5 cable at the thin client, or to move the thin client to another network drop. This has me thinking there's a problem with the cat5 cabling (the office is going through a major renovation). But, I'm not 100% that is the case. It could be a problem with the dhcp server.

...d be using pri but i am not sure,. i also am not sure if i would be using 1-24 kewlstart or 1-23 + 1 delta. I am also not sure if i need any extra configuration since they are p2p, do i need to set timing on one end? Also for the wiring, i have a verizon smartjack for the p2p t1 and i am running cat5e from the smartjack to the asterisk box, do i wire this like a standard ethernet cable t568b? or does it need to be wired differently? Verizon was going to install it but then they told me they DO NOT use shielded cable which i thought was needed, so i decided i would do it myself and save some m...

Hey All, I have a user whose Cisco 7960 died the other day. When you disconnect the Ethernet cable the phone boots (as far as it can w/o network connectivity) but as soon as you plug in the CAT5 it goes dead. (no lights, no sound, no display, nothing) I tried to contact Cisco but they say I have to contact the vendor. I have sent an email to the vendor (www.thevoipconnection.com) and I am waiting to hear back from them. I have asked Google in every possible way I can thing of and I have...

Hi there, what phones are available that have two ethernet ports? I want to do some cabling at a new installation and i heard there are such phones (SIP i guess) out there. That way i dont have to run two cat5 to the user desktop. I think 3COM had one but can't find the web site reference for the two port phone thanks, erick
