help me out on this and show me the right direction?

Generally, only 30 channels of that E1 are usable for voice. One of the
channels is devoted to timing and another one of the channels is generally
used for signalling. The channels are usually signalled thusly:
zaptel.conf (upcoming as /etc/dahdi.conf)
bchan=1-15,17-31,33-48,50-62
dchan=16,47
and:
zapata.conf (upcoming as /etc/asterisk/chan_dahdi.conf)
pri_cpe=1-15,17-31,33-48,50-62
The channels are accessible in Asterisk as Zap/1, Zap/2, etc. up to Zap/62.
Note that you MUST keep the gaps for the D channels.

What kind of machine do i need to process 32 calls (or 64 calls incase i
buy a 2 port E1 card).
|
Any modern machine should work fine. Single core, 1.2GHz should handle it
fine, and any extra hardware you throw at it will be gravy.

Will all other channel technology configuration files be renamed to follow
this pattern (chan_<technology>.conf) or will DAHDI just be an anomaly?

You can do "genzaptelconf" to get a general framework to then edit.

I think it was only done this way because there's a kernel-level config and an
Asterisk config file, so this was done solely to make the name different (and
try to avoid confusion). I'm not necessarily opposed to changing the other
channel drivers, though.

So would it make more sense to change the name of the kernel level conf
file instead of introducing this inconsistency and causing much gnashing
of teeth amongst the users opposed to any change?
Not that I get to, but I'd vote for /etc/dahdi-kernel.conf and
/etc/asterisk/dahdi.conf. But then, I would have voted against DAHDI in
the first place 
Thanks in advance,

Thanx a lot Tzafrir and Tlighman. But i need to clear some more concepts
before starting to implement anything.
In ATFOT i read about configuring an analogue pstn line, by configuring
/etc/zaptel.conf and some other things in etc/asterisk/zapata.conf, that was
just one line. if I configure the E1 card then ,correct me if im wrong, i
will have similar 32 channels like that single pstn line in TDM card, The
only difference will be the number of channels?
what are b & d channels and whats the difference between them?
Talighman..
Can a 1.2GH machine handle 62 CONCURRENT zap calls?
If you can provide me a good source where i can find all the necessary
info then it will be more easier and faster for me.

No. As I said before, you will have 30 channels of voice. Not 32.
| Quote: | what are b & d channels and whats the difference between them?
|
Bearer channels can transport voice. The data channel is used exclusively
for signalling.
| Quote: | Tilghman..

That would be 60, not 62. Remember, there are 2 D channels, one for
each circuit. I provided the 1.2GHz speed as an example of the minimum
you will probably need, as long as you do no transcoding, conferencing, or
other tasks which would up the CPU load. If you do either of those tasks
(or the myriad of other tasks, like running a database on the same machine),
you will need more CPU. And given that a 1.2GHz machine is now generally
more expensive than most new machines (which are considerably faster), it
would probably be a wise choice to get the fastest machine for your money.
I don't know what exactly is the sweet point on processors this month, but
it's probably around 2.2GHz dual core.

span=4,4,1,esf,b8zs
What does this statement do. What do different values separated by comma
mean. Also the last option "b8zs", i read about it that it is only used in
T1s, so if i use E1 then what should i put there. I read somewhere that E1
uses HDB3 instead of B8ZS. Is this write?

Configs for a live four port Digium T1 card. genzaptelconf took care
of it for me, Sangoma has an install script that generates these files
as well. Intel(R) Pentium(R) 4 CPU 2.80GHz.

What does this statement do. What do different values separated by comma
mean.

That is generally explained in the zaptel.conf.sample in the zaptel
source tree.

T1s, so if i use E1 then what should i put there. I read somewhere that E1
uses HDB3 instead of B8ZS. Is this write?

Go to www.voip-info.org and read.....
I was giving you an example generated by genzaptelconf for a T1, I am
assuming that if you set the jumpers on the board to E1 or it is an E1
card, genzaptelconf will create the appropriate settings. I know the
Sangoma scripts do.
If you have issues with your setup, sometimes crc4 can cause issues.
The LED on the card flashes from greed to red quickly was the symptom
I found.
Thanks,
Steve Totaro |
