This +is how to check them out from the public subversion server. + +These are the commands you would type to install them: + +`svn co http://svn.digium.com/svn/zaptel/branches/1.4 zaptel-1.4` +`cd zaptel-1.4` +`make; make install` + +`svn co http://svn.digium.com/svn/libss7/trunk libss7-trunk` +`cd libss7-trunk` +`make; make install` + +`svn co http://svn.digium.com/svn/asterisk/trunk asterisk-trunk` +`cd asterisk-trunk` +`./configure; make; make install;` + +This should build Zaptel, libss7, and Asterisk with SS7 support. + +In the past, there was a special asterisk-ss7 branch to use which contained the SS7 code. +That code has been merged back into the trunk version of Asterisk, and the old asterisk-ss7 +branch has been deprecated and removed. If you are still using the asterisk-ss7 branch, it +will not work against the current version of libss7, and you should switch to asterisk-trunk +instead. + +CONFIGURATION: +In zaptel.conf, your signalling channel(s) should be a "dchan" and your bearers should +be set as "bchan". + +In the asterisk-ss7 branch, there is a sample zapata.conf that is installed which +contains sample configuration for setting up an E1 link. + +In brief, here is a simple ss7 linkset setup: + +signalling = ss7 +ss7type = itu ; or ansi if you are using an ANSI link + +linkset = 1 ; Pick a number for your linkset identifier in zapata.conf + +pointcode = 28 ; The decimal form of your point code. If you are using an + ; ANSI linkset, you can use the xxx-xxx-xxx notation for + ; specifying your linkset pointcode. +adjpointcode = 2 ; The point code of the switch adjacent to your linkset + +defaultdpc = 3 ; The point code of the switch you want to send your ISUP + ; traffic to. A lot of the time, this is the same as your + ; adjpointcode. + +; Now we configure our Bearer channels (CICs) + +cicbeginswith = 1 ; Number to start counting the CICs from. So if Zap/1 to + ; Zap/15 are CICs 1-15, you would set this to 1 before you + ; declare channel=1-15 + +channel=1-15 ; Use Zap/1-15 and assign them to CICs 1-15 + +cicbeginswith = 17 ; Now for Zap/17 to Zap/31, they are CICs 17-31 so we initialize + ; cicbeginswith to 17 before we declare those channels + +channel = 17-31 ; This assigns CICs 17-31 to channels 17-31 + +sigchan = 16 ; This is where you declare which Zap channel is your signalling + ; channel. In our case it is Zap/16. You can add redundant + ; signalling channels by adding additional sigchan= lines. + +; If we want an alternate redundant signalling channel add this + +sigchan = 48 ; This would put two signalling channels in our linkset, one at + ; Zap/16 and one at Zap/48 which both would be used to send/receive + ; ISUP traffic. + +; End of zapata.conf + +This is how a basic linkset is setup. For more detailed zapata.conf SS7 config information +as well as other options available for that file, see the default zapata.conf that comes +with the samples in asterisk. If you would like, you can do a `make samples` in your +asterisk-trunk directory and it will install a sample zapata.conf for you that contains +more information about SS7 setup. + +For more information, please use the Asterisk-ss7 or Asterisk-dev mailing +lists (I monitor them regularly) or email me directly. + +Matthew Fredrickson +creslin@digium.com + |
