Building a MAP gateway

Is anyone familiar with developing an application sever (running on a Solaris unix box) that is able to "speak" with a Cisco ITP?

The application would be instructing the SMSC to send out SMSs. The setup wuld similar to this:

Figure 8: Cisco ITP SMS Multilayer Routing for Tele-Voting

My intended setup:
[APPLICATION SERVER] -> [CISCO ITP] -> [possibly a MSC] -> [SMSC]

The communication for the [APPLICATION SERVER] -> [CISCO ITP] would be over IP

I think I would be sending MAP messages (with the instructions for the SMSC) from my application server to the Cisco ITP. Thats the part I need help/info on. How could this be done? Anyone here ever done it before?

(I would be doing the coding (in Java), I am by no means a SS7 expert (at best I am a beginner). I have just been trying to familarize myself thus far with SS7, SIGTRAN and SCTP etc.)

Any information/suggestions would be greatly appreciated.

Essentially I am wanting to replicate (on my unix application server) the SS7 MAP Gateway functionality seen in the diagram below:

Sure. Lots of application servers do this.

The package that I am familiar with is the HP Opencall, which is a Sigtran atack, wherein you send the traffic, it converts to Sigtran , and out to the Cisco ITP. ITPs can convert to TDM, if this is needed by the Signaling Gateway.

OpenSS7 (openss7.org) also has a Sigtran stack, but it is a little flakey. I couldn't get it to run right for me.

Most SMS is sent via SMPP these days, however.

If it is just receiving and sending SMSs from SMSC, why don't you use SMPP to connect and
send msgs to SMSC. SMPP also is on TCP/IP.
Or, there is any specific requirement or restrictions do like this as you mentioned in the setup?
In that case solution suggested by RussCrush seems to be good.

RussCrush/Anil

Thanks for your responses. You both suggesting connecting to the SMSC, I should have pointed out that in my solution I only have access to the Cisco ITP (no direct connection to the SMSC) via my Application Server.

Also, I am trying to build the application from scratch. So RussCrush, I would essentially be trying to build the HP Open Call Application you suggested where I am specifically focusing on the MAP Gateway Functionality (well....something like that). And I specifically would want to actually build the application (unless of course there is a site that I could go and download the MAP gateway to my unix box  :))

Do you know of any code or similar Open Source application/code I could take a look at (apart from OpenSS7 Sigtran stack)

(Oh....my "budget" is essentially $0.00, I hoping to do this with whatever resources I can find online and books I have available to me)
