E4 Superframe E&M?

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?

Thanks,
Jon

You have {EXTEN}shouldnt it be ${EXTEN} (or is this AEL) ?

Here's what worked:

exten=>_X.,1,Dial(SIP/"prefix"${EXTEN}@outbound trunk)

substitute "prefix" for the tech prefix you would like to append.

Sounds like ESF-based T1 CAS with E&M wink signaling to me...?

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.

I think you misheard "D4 Superframe" and yes, that's supported. "d4,ami" in
zapata.conf in the span definition.

use this

e&m=1-24 ; 1-32 for E4


zapata.conf

Thanks to everyone who has responded so quickly to my question.

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

It's invisible to Asterisk, this is a layer 2 issue. All signaling that
you care about will work the same way as you expect.

i need sleep that is for sure.

the 1-32 for E4 stuff was meant to be for E1 stuff you can just increase
the channel count. (1-31)

if possible, yes, because you get the added error information with ESF.

using d4,ami with em signalling has worked for years for us (on 1.2).
i have not tested it with 1.4

if i were you, i would 'test' the above settings first, then change to
ESF. that way at least you will have something to fall back too.

Ok finally setting this up. How do I debug since it is not PRI?

I have a Sangoma card and four tie lines. When i try straight through
cables, I see the channels starting and stopping but no green light on
card or solid light on proprietary system.

How to debug? I have tried straight thru T1, crossover 1-4,2-5,
crossover 1-5,2-4, and em_w, em, master, slave, and every combination.
Strange thing is that when the CLI was reporting simple switch
open/closed is when the other end of the cable was just dangling in the
air! I finally thought I was getting somewhere too.

Just for the record. I had to reconfigure the Sangoma startup scripts
even though my zap files were correct with d4,ami.

The real gotcha was in the cabling. One crossover was 1-5, 2-4, the
other 1-4, 2-5 and then straight through all required for the same
dialer. I have seen people post T1 crossover as 1-4, 2-4 but I thought
they didn't know what they were talking about. Now I know that there
are actually two different kinds.

sorry about that i just got back in town.

I have been lucky with only needing one type of crossover cable.

D4 superframe - more bits are used for chan signalling, results in 56k
voice channels.
Extended superframe - fewer bits used for chan signalling, results in
64k voice channels.

Otherwise basically the same, both are 1.544 mbps. If the T1 goes down,
D4 takes longer to frame up than ESF. But for pbx to pbx, aren't they
going to be located in the same room?
