similar to: Channel Bank - Vina T-1 Integrator

Thanks Brian, and thanks again for the included definitions <grin> - that helped too. Your comments are really helping clear many questions. I suppose our intensions are to become an IXC. So if my local carrier is sporting old technology, they'll provide TDM services. So if I understood you correctly, the "in-band signaling" is typically SS7, and the alternative is typically

I'm considering switching my incoming phones lines from standard analog to a T-1 service from XO communications. They propose to bring in an "IAD" which has 12 lines of voice and 768k of internet bandwidth as part of a package deal. Since I want to keep the voice traffic in the digital domain the equipment they're proposing is a "Lucent Digital Vina Integrator" IAD

Pardon my ignorance, but I was hoping someone could clear up something for me. - For a few POTS lines, digium has a single port card for that, or a T1 card to a channel bank. - For 10 or more lines, digium has a T1 or E1 card for that too based on PRI channels - For 100's to 1000's of lines, I suspect a soft-switch is in order??? A traditional phone company will sell: - POTS lines for

I need to know how to setup the data side of the T1 on my Linux Box. I have found information about configuring a PRI and HDLC but nothing about the Frame-Relay type setup for data. The following is information from our T1 provider. Network T1: Framing = ESF Line code = B8ZS Build out = 0-133ft(DSX)/0dB(CSU) Clock = network Pulse-density-enforce = off alarm-option = on alarm-delay = 15

As a follow-up to my previous post where I stated the IAD would be a Vina model, after some more prodding to XO, they have told me it will either be an Adtran TA-600 or a CAC Adit 600. These products are covered pretty well on the web and I have manuals on both. So, if those knowledgeable folks had to use one of these to attach to an Asterisk box, what interface would be best or at least

I'm looking to buy a channel bank. I'll be using this to basically dual a Toshiba PBX and Asterisk so that we can deploy Asterisk in small steps and have the Toshiba as a fallback in case something goes wrong. What I need is a channel bank that will allow me to take in 12 lines using the FXO ports in the CB and then output those lines to the Digium T100P. Has anyone had experience

Hi, all I wanted to fetch data from Bloomberg for govt bonds, and analyse it further. I am having trouble in getting data as when I use field=PX_LAST, it is giving the prices but when I use field=CPN, or ISSUE_DT, it is not giving the results and just bouncing back <NA> for that. This is the piece of code: > library(rJava) Warning message: package 'rJava' was built

Hi, I am fairly new at working with Asterisk. I am having a call quality issue that I really need to get ironed out before we go to rollout the system in a week. Any help would be greatly appreciated!!! Even if it is just pointing me in the right direction. My current setup: I have Asterisk Setup on a Dell Server. It has 2 T100P cards. One will be for out T1 PRI from the Phone Company (We

Hi, friends. I keep coming to you because I'm so new to R and can't seem to figure out some simple things. Sorry. Consider the following code. I want to load a table and write out the structure to a PDF document. I just can't seem to manage writing non-graphic output to PDF. Any help? I've tried several functions, but nothing worked. All I get is the title. #

Hi, all. I'm new to R. I've been a SAS programmer for 20 years. I seem to be having trouble with the most basic task - bringing a table in an *.RData file into a data.frame object. Here's how I created the *.RData file. library(RODBC) db <- odbcConnect("*******") df <- sqlQuery( db , "select * from schema.table where year(someDate)=2006" ) save(

Hi, all; I'm new to R. Have been a SAS developer for over 20 years. Whenever I create a new table - you call them dataFrame objects - or modify an existing one, I like to open the table in a grid with horizontal and vertical sliders so that I can scan across the table and (especially) look at all four corners. If I made a gross error, it often shows up when I look at the corners of

Hi, pretty new with R and LaTeX here... I'm trying to use the latex() function from the Hmisc table with Sweave. When I try: pdflatex myfile.tex I get an error that reads: ! Undefined control sequence. l.22 \ctable It seems like this is an optional package for Tex that I haven't installed? My googling skills have neglected to locate instructions for how to install ctable on a Mac,

I've been having some problems getting a channelized T1 working with a T100P card. Perhaps someone can help: I have an Eschelon T1 coming into a Vina Integrator box. This box splits out the T1 into an ethernet plug for bandwidth and a secondary T1 which I plug into the T100P card. I've connected the two with a T1 crossover cable. I get a green light on the t100p card and can make

Hello, I would like to make sure I am not going to shoot myself in the head, so I would appreciate if you could tell me if what I am willing to do is realistic (and will work) or not. I am willing to replace our office "London" phone system when a new E1 (G703) is installed later this month and I have the choice between using asterisk or a more classical hardware PBX. The planned

Gentlemen We are attempting to use * in a simple switching application: +-----> office lines | V LEC <--PRI--> * <--PRI--> modem bank (56k dialup modems) The problem is that (even with no office lines active) the modems have difficulty establishing a connection, the connection is slow (way too slow for 56k modems) and the connections are

I have a vibration signal coming accelerometer. I converted this signal from* m/s^2* to *mm/s*. Now I am supposed to predict this vibration signal in R using historical data. (Please see the attached picture of vibration signal). Can I use this vibration signal just like that to the prediction using predictive Models or Do i need to do some processing technique before doing prediction? Are there

Hey all, I've got a PRI used for data calls right now, terminated in a MAX 4000. We're only using around 12 channels on average and 16 max, so I'd like to split off the remaining channels to terminate in an Asterisk box. Does anyone know of a device that'll take a PRI in, and spit out two PRI's that share the channels? Also need to be able to do some sort of call routing so

I've searched all the archives and can't find anything relating to my problem. I have a 128 node cluster. Al NICS are Nvidia. I have them on a network with other machines. I do PXE installs of Fedora on them. These 128 nodes have a problem with the install. The initial DHCP requests get answered, the machine accepts and then the TFTP sequence takes place. The second DHCP request is

I'm looking for people who have an xbox360 joystick to help run some tests so I can get information on implementing xinput for wine. The more 360 joysticks plugged in the better. Can you please go to the forum post I made and test: http://forum.freegamedev.net/index.php?t=msg&th=1980&start=0 Thanks, Andrew
