I need to create a couple of tie lines between a legacy system and an Asterisk system. I was told that the tie lines are E4 Superframe E&M. I have done E&M wink but have no idea about E4 Superframe E&M and Google is not helping me here. Does anyone know about this type of signaling and if Asterisk can handle it? Thanks, Steve
There used to be a prefix command in asterisk, it doesnt seem to work any more. How can I add a prefix to an outbound call?

Sounds like ESF-based T1 CAS with E&M wink signaling to me...? On Tue, 16 Oct 2007, Steve Totaro wrote:> I need to create a couple of tie lines between a legacy system and an > Asterisk system.

I was told that the tie lines are E4 Superframe E&M.That sounds like a miscommunication; they probably meant D4, which was the framing method used before ESF came along. See the Wikipedia page about DS-1 for more information. In zaptel.conf this can be specified by using 'd4', 'sf' or 'superframe'. It is likely that this T1 is using AMI for line coding as well, because most systems that use B8ZS line coding use ESF for framing. -- Kevin P.

"d4,ami" in zapata.conf in the span definition. -- Tilghman

To my way of thinking, it would be better to have the legacy tie-line reconfigured to use esf if possible. Is D4 (superframe) well supported in Asterisk, are there less features? If it is virtually the same, then I guess I will just setup Asterisk to use it rather than messing with the legacy system. Thanks, Steve
