Dear list, I have a vector (array, table row, whatever is best) of frequency values for categories (or bins), and I need to 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

Hi, I am having some difficulties with matrix operations. It is a little hard to explain it so please bear with me. I have a very large data set, large enough that it needs to be split in parts in order to deal with. I can work things on these "parts" but the problem lies in adding together these parts for the final answer. So that been said, let's say that i split the data in 2

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

Hi there Just a quick question, I will be building some servers in a lab utilizing Digium E1 cards. I would like if possible to avoid the expense of installing an e1/ISDN30 in my lab. I have two questions really, first does anybody know of an effective simulation 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

Hello Everyone, I'm running a dhcp server on CentOS 4.4. It's providing IPs and remote booting for a number of thin clients. I've recently had problems rebooting a few thin clients. Here is the error I've been seeing: Jan 16 14:16:45 at01 dhcpd: DHCPRELEASE from 00:40:63:e5:71:4f specified requested-address. Jan 16 14:16:45 at01 dhcpd: DHCPRELEASE of 10.1.1.150 from

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) ?

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

Hello all, this is not really an * question but it is somehow related, i am trying to develop a working proposal for cheap and quick telephony services using Voip running over *. By running a wireless network (over 802.11 a/b/g devices), i plan to be able to reach customers directly with eithe table top or handheld 802.11 sip enabled phones. But the disadvantage is that how do i power each radio

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

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.

Hello all, We've discovered that VoIP (IAX2) + Citrix + Video is pegging the measly CPU on the Netopia router our ISP provided. We've got 3Mb/3Mb and will increase to 4/4 next year. The Netopia simply breaks out our WAN IPs, and we've got a switch hooked up to it on the inside (Actually I've got a QoS box in-between). ------------- | Internet | | on Cat5 | -------------

Hi All, Need some information on getting the right storage array to buy for my cluster configuration can anyone help me with this my Setup so far 2 Athlon 2800 Sempron System 1 Wti Network power switch 1 24 Port 10/100 Cat5 switch 2 Adaptec 39160 scsi host adapter pci cards installed in the systems. I need to know what is the best storage solution with this configuration Thanks

>From their website, the key difference between the polycom 500 and 600 phones is the number of "lines" they support. What does this mean in terms of asterisk? Do I have to have a seperate extension for each of these lines or ? Also, slightly off-topic, how does the 500 POE "optional" cable work? Is this similar to have a power box on your desk, or is just a differently

Before committing to about 50 of the spa942's, I like to take a last poll from those on the list to identify any negative issues that might be associated with the audio, functionality, early failures, etc, on the spa942. Expecting to deploy these using existing cat5 cabling and both rj45 jacks. Been using three of theme in a short term demo with the customer, but the demo systems has

The "telco guys" probably did something non-industry standard and reversed send and receive in the jack that they plugged the CAT5 into. Sure it works, sure it is easier, sure it is not the correct way of doing things.

Hi again folks! ;) As before, I will transform one E1 30 Channel PRI into 30 FXS channels using Adit 600. Now I'm into choosing server platform. And the two opponents are: * Dell PowerEdge 750 w/ SCSI RAID (or even SATA RAID1) * FujistuSiemens PRIMERGY RX100 S2 (SATA RAID1) As I've seen people having problem with HP server, I havn't looked at it at all. What experience do you

All, I need help. I have an (actually 2) Adtran TA750's with 8 FXO ports. I get a terrible buzz on every FXO port. If I unplug the Adtran and put an analog phone on each incoming line, I have no buzz. I also have 2 Carrier Access Access Bank I's with 12 FXO ports. When I plug the same analog lines into either one of those, no noise or buzz whatsoever. I went so far as to move the TA750

Hello all. I've been a fan of the xiph project for some time, thank you for your excellent work. I am looking for a fully-developed, beta, or alpha open-source hardware platform for remote deployment to terrestrial fm transmitters and streaming to general internet listeners. Willing to participate in development/beta testing of projects or possible $ support for an existing project. Able
