Re: [asterisk-users] bandwidth required for Asterisk running on T1
That sounds like an E1 to me. Is that 32 DS0 channels or 24? On Fri, Apr 11, 2008 at 4:18 AM, mark morreny [EMAIL PROTECTED] wrote: Hi, The T1 is 32 x 64Kbps channels ; Codec is GSM.

Hi Andrew, Yes, it is actually a E1. Your suggestion will be greatly appreciated. Thanks, Mark On Fri, Apr 11, 2008 at 7:50 AM, Andrew Latham [EMAIL PROTECTED] wrote: That sounds like an E1 to me.

Re: [asterisk-users] bandwidth required for Asterisk running on T1
Using the online calculator mentioned in this thread will help. There is a lot to bandwidth and even more to VoIP network traffic than can be answered with your question. On an E1 that is dedicated to IAX terminating to a provider that does trunking I would say that you could get a large number of concurrent calls through On the other hand if the calls where SIP u.law and going to different network destinations you may only get a few concurrent calls to work. Its like a good bottle of wine, the bottle is just the container On Fri, Apr 11, 2008 at 11:15 AM, Pete Kay [EMAIL PROTECTED] wrote: Hi Andrew, Yes, it is actually a E1.

Re: [asterisk-users] bandwidth required for Asterisk running on T1
Additionally Mark, a Channelized (also called Integrated) T1 offers 24 channels for voice/data, but after bit robbing (for signalling, etc) you only get around 56kbps per channel. ISDN PRI over T1 has 23 b-channels of voice/data and one d-channel for signalling, etc. PRI is preferred and most common. And of course, ISDN PRI over E1 gets 30 channels of voice/data and 2 channels for signalling.
