Steve. You are saying this from your view of 2004. But at the time R2 was developed there were no microcontrollers and tones were decoded with LC filters. R2 provides interactive capabilities base on a simple tones protocol to retrieve ANI, dialed numbers, signalling status etc. It's compelled structure provides some kind of handshaking to deal with different kind of switches and their speed. Nowadays this is no issue at all but at the days R2 was developed you had to take into account that relays and step by step switches take their time.
On the other hand I have to agree with you... Well, what is the definition of sane anyway :-) Regards. Alfred. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Steve Underwood Sent: Monday, January 19, 2004 5:08 PM To: [EMAIL PROTECTED] Subject: Re: [Asterisk-Users] R2 support Olle E.

I'm curious. Half of R2D2, of course. Its also a stupid clunky multi-tone based telephone signaling system widely used over E1s in South America, Asia, and parts of Eastern Europe. No sane telecoms engineer would use it. However, few telecoms engineers are entirely sane :-) Regards, Steve _______________________________________________ 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
