Zaptel E1 pulse signalling not working

Asterisk Asterisk Support
1

I am trying to get a TE210 card to run E1 with pulse signalling on Asterisk.

The E1 span works fine for outging pulse signalling, but won’t decode incoming pulse digits.

When my setup is reset to DTMF everything works well in both directions.

When set to fxo_ls incoming pulse signalling works well.

It looks as though any incoming pulse dialling is being interpreted as a meaningless jumble of flashes and winks.

My setup is as follows

asterisk-1.2.10
zaptel-1.2.7

zaptel.conf

span=1,0,0,case,hdb3
e&me=1-15,17-31

zapata.conf

immediate=no
signalling=em_e1
pulsedial=yes
channel => 1-15,17-31

In the event on in incoming pulse call i get the following

– Starting simple switch on ‘Zap/1-1’ *** Incoming call starts

and so on.

Also does anyone know how to elegantly change the idle pattern on an E1 E+M link as I have had to interchange the bits in wct4xxp.c (in t4_rbsbits() for outgoing and t4_check_sigbits() for incoming)

Suggestions welcome!

In your zaptel source, edit the file “zconfig.h”. Uncomment the “#define EMPULSE” line and recompile Zaptel. Make sure to reload the zaptel drivers also. This should do it for you.

Thankyou - that works perfectly.

I did note that that #define EMPULSE is only in the svn version and am curious as to why it isn’t in the releases.

Because it was a new feature and only bug fixed get put into the branch/releases. It will be in the new 1.4 release though.

My zaptel.conf

span=1,1,0,ccs,hdb3,crc4
bchan=1-15,17-31
dchan=16

span=2,1,0,ccs,hdb3,crc4

dchan=47

Global data

loadzone = au

and zaptal.com:

switchtype=national
pridialplan=unknown
prilocaldialplan=unknown

group=1
context=incoming
channel =>1-15
channel =>17-31

i have spent lot time on it could not figure it out. Also does not work for incoming calls.
