MTP2 has a well defined interface (in the form of functional calls) with the hardware, which is to be ported. This is EXPLAINED in detail, in the MTP2 Porting Guide. 

The multiple SS7 links are handled by the hardware in any fashion (polling in round robin or any other manner/ interrupt driven) – MTP2 PLACES no restriction on this.

MTP2–hardware interface CONSISTS of a SET of functions, which are invoked by the hardware as needed :

• Whenever the hardware is READY to transmit, it will invoke a well-defined MTP2 function.
• Whenever the hardware has received a signaling unit, it will invoke another MTP2 function.
