OK. Now I show my ignorance. What's the difference between a T-1 and a channelised T-1? I see that Covad's voip service (formerly GoBeam) requires a channelised T-1. Then I read recently on the list that many T-1s being installed are actually HDSL....which would be not a T-1 at all...right? Michael -- Michael Graves mgraves@pixelpower.com Sr. Product Specialist

Dear all I have a dataset examining the probability of a population surviving (calculated from a logistic regression) of a species over a 200yr period. The predictor variables are either continuous but non-normal (e.g. temperature, oxygen) or categorical (e.g. channelisation), unfortunately I also have a large amount of missing values.

Hello, I am looking to buy a large number of TE410P cards for a big international project. I have studied the documentation and zaptel.conf and as result I have the following questions: 1. How do you switch the card from ISDN PRI TE to NT? This means from being configured as User Equipment (the PABX) to be Network Equipment (the Exchange). 2. How do you configure the card for E1 or T1? 3. In

Hi Please check out this product http://www.sangoma.com/products/hardware_products/data_networking/a301.html Does it work on Asterisk or Freeswitch ? Do Telcos provide an E3 connection ? One of our customers had an inquiry for terminating 6000 calls simultaneously. I want to do some homework before taking it further with him. If I use E1 lines, I will need 6000 / 30 = 200 E1 lines, which does

All, I have done research on VoIP for some time now. I'm a Cisco certified Network Engineer however Telecom is not my strongest suit. I've been a part of this mailing list for sometime but my delusions of grandeur in migrating our 25 year old phone system to a new platform have been on the back burner, until now. I have found my company is moving to a new location(building) and this

I'm experimenting (using for the first time) with using a cisco3620 to connect to the PSTN via a channelised E1 interface, with * handling all of the SIP calls. If anyone has any installation tips / help / documentation I would be most appreciative :) However, my first question is this: when I am in the setup, I see the following: Current interface summary Controller Timeslots

I'm trying to access feature codes remotely over a channelised T1 between a Norstar MICS (rev 4) and Asterisk. The timeslots are configured E&M and have been working fine under most circumstances except this one. There is mention of accessing the facility by calling Flash() from within extensions.conf, but I can't get it to work... Right now I can't tell if it's because

I've noticed a problem with calls to Hangup when talking to my Norstars over channelised T-1 E&M trunk lines - it's been present since I started to fiddle with Asterisk last December and it's still present in 'Asterisk CVS-HEAD-08/13/04-10:37:13'. Specifically, when a call is connected to Asterisk from the Norstar DTI card to my T100p I get the following conditions

Hi List, I have stupid question but I want to know it. Why we use the PRI insted of BRI ? Just for the sake of number of lines or any thing else ? And why SIP is used for making calls rather then IAX? Even we know IAX takes 1 channel for making calls? ----- Thanks and regards Virendra Bhati +91-9172341457 Asterisk Reader -------------- next part -------------- An HTML attachment was

Hi, Inspired by a recent rant about one particular provider, I am getting very curious about something I've never mastered. I'd like someone to explain this here or at least post a link or two that can educate me and probably countless others who have no knowledge in this area. I'm sure there are several of you reading this that know all about the subject. What are the various

Any know what Digium hasn't released the DS3 card? It was supposed to be out a while ago. -Matt
