Sub: INTRODUCTION FOR SUPPLY OF SPECIAL CABLES We have pleasure in introducing ourselves as manufacturer's of specialised cables for over two decades catering to the needs of the Fertilizer, Chemical, Petrochemical, Oil & Gas, Steel, Power, Cement, Ceramic, Glass, Paper, Sugar and other industries. The following are some of the cables made by us: ANY CABLE, ANY TIME, ANY QUANTITY

I was once told by a lineman that the cables they use didn't have that many twists in them because it wasn't needed, and that the extra twists would effectively use more cable and thus 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

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

When I bought two Polycom 501 SIP phones, I naively thought they were Power-over-Ethernet (IEEE 802.3af) because they were "powered over ethernet." Silly me. Polycom must have some odd voltage or funny way of injecting the power, because the POE switch I bought for them (Netgear F@510P) won't power them, though if I use the Polycom-supplied AC adapter and ethernet power

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

At Sangoma we do quite a lot of back-to back T1 and E1 connections. T1 is not a very fussy connection, as the baud rate is only about 750 kbps. In our experience, for error free communications you can use the following rules of thumb: Up to 50 ft: Flat patch cable Up to 500 ft: Ordinary twisted telephone cable Cat 5 may be overkill unless you are going hundreds of feet.

If this is a cable company, it is likely that the cable to the cable modem splits off to the TV(s). Make sure there are not any unterminated co-ax cable which used to go to a TV. Make sure the cable outside the house is not damaged. The cable company can test for bad cable at your

Hi everyone, This is not directly NUT related, but i don't know where else I can still ask this. I have been using a pretty decent 2nd hand MGE ellipse premium 1200VA for a while now at home. http://www.mgeups.com/download/doc_intl/ small/premium/389uk.pdf It's been working very well for me on linux, but my linux server has recently passed away and now I only have Macs left.

Two questions that was not always clear for me [sorry for posting to this list :\]: ############################################################################################## Q1) when cabling, is the color order important? like: straight cabling: A side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown could be eg.: like this??

I have a Cisco 7960 phone. I cannot seem to use the settings button to get into the phone to change the TFTP server. I've set up a DHCP Server, TFTP Server with the same address, and the phone requests the address of 0.0.0.0, the server offers the address of 192.168.2.2, but the phone seems not to take it. I have no action on the TFTP side. So, since I can't seem to server the phone

Hi, folks: I just took delivery of new PoE cables (PN 2200-11077-002) for our Polycom phones here in the office. I have the following to report, for the erudition of existing Polycom users and those considering purchasing Polycom sets from the set of models noted in the subject: 1. The cables do indeed work (hooray). 2. The cable has a module on it about a third of the way from a female end.

Is there a cable length limit to use with a fxsmod (TDM400B) ? I noticed that if I use a very long cable 148 feet, I can hear some parasite : I hear the radio ! If I use a short cable, there is no problem... Thanks for help, St?phane HENRY

Hello everyone. I have a timing slips errors and I can't understand what source of the problem is. My installation has 2 digium cards: TE420 and TE220 cards in one server. There are 3 spans (E1) to PSTN and 3 spans to internal PBS stations - normal installation for transit communication. Span configuration is: span=1,1,0,ccs,hdb3 #TE420 - first port. To PSTN. span=2,0,0,ccs,hdb3 #TE420 -

I'm connecting a T1 PCI card to a Nortel Option 61 switch T1 card. My Sangoma A102D shipped with 2 T1 cables - which I assume are straight through. Do I need to make crossover cables for this scenario? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

I for one think it is a great idea to buy a book with hard earned money and wait a few days to a week just to get an answer to a question that is freely available on the internet immediately. Hard pressed to think of anything in the "book" that is not on with wiki with more up to date and useful information. -----Original Message----- From: Alexander Lopez

I've got a big UPS from an italian manufacturer MSC elettronica which should be megatec protocol based. They distribute it with Upsilon2000, developed by Megatec, and with a cable listed on the megatec site: http://www.megatec.com.tw/FAQ.htm How do I know the M2505 cable is the one that should be used on my UPS instead of M2502 cable? UPS that use both these cables are TRUE RS232 UPS
