You are aware that DSL (even SDSL) is half duplex and a T1 is full duplex, right?
1.5m sdsl can only do 768 sustained duplex, or 1.5 out 0 in, or 0 out 1.5 in. a T1 will do 1.5 in and 1.5 out sustained. This is due to a separate transmit and receive path on a t1 and a shared path on sdsl. The s in sdsl means symmetrical, not duplex, that is that the signaling rate is the same in either direction, but still half duplex. For VoIP a t1 is worth double what a 1.5 sdsl is because of the duplex nature of the traffic, unlike most internet that is download-centric. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Wiley Siler Sent: Monday, June 13, 2005 9:43 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] Should I choose DSL @ 1.5 or a full T1?

Don't know if I'm getting a break for having a voice and a data circuit broken out from one fiber drop, but that's what I'm paying here in Orange County. Also, I had a business cable modem before, which was *allegedly* not shared for business customers (suspicious) and the throughput was a roller coaster, as was the latency. The DS-1 cleared all that up. /rg Robert Goodyear Brand Up LLC http://www.brand-up.com _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
