[asterisk-users] ISDN & SS7

[huu giang]

How can you caculate the number of call an SS7 channel can handle ?.
I have a E1 line, can I just need use 1 channel for SS7 signal, and other 29 
channels for data tranmission ?. Is it OK.

Giang

I do not have knowledge of the SS7 vendors for Asterisk.  Using redundant 56k 
data channels, we handle calls via 6 DS3s (672 X 6 calls) from the PSTN on a 
commercial telephone switch, with no issues at all.
 
SS7 can support any number of simultaneous calls depending only on the bandwidth 
of the SS7 channels.  SS7 is always done on a redundant channel basis since it 
is so important.

Hi cary,
 
Can you recommend me what add-on vendors I should use ?
Can a open source solution such as chan_ss7 or libss7 support many conncurrent 
calls (for example 240 calls) ?
 
Thanks

SS7 is an inter-telco system using a separate network for all signaling.
 
You must have an SS7 network connection before anything will work.
 
Then the T1 Spans run 24 64k audio paths.  The SS7 net exchanges the call data 
and connection info between the switches.
 
Asterisk doesn’t support SS7 natively although I believe there are one or more 
add-on vendors.

Hi all,
 
I'm being requested to deploy an IVR service using SS7. 
I've deployed Asterisk before using ISDN connection, but never with SS7.
Can anyone explain me the different between using ISDN and SS7 ? What need I do 
now to change to use SS7 ?.
 
Many thanks,
Giang
