A distributed signaling system seven (SS7) call handling system (107) includes an SS7 message transport protocol level three (MTPL3) processing module (202), an SS7 message transport protocol lower level (MTPLL) processing module (258), and a local interconnection media (240). The SS7 MTPL3 processing module (202) includes an SS7 MTPL3 network layer (204) and an MTPL3 local network interface (218). The SS7 MTPLL processing module (258) includes an SS7 message transport protocol level one (MTPL1) physical layer (259), an SS7 message transport protocol level two (MTPL2) link layer (256), and an MTPLL local network interface (254). The local interconnection media (240), for example an Ethernet, couples the MTPL3 local network interface (218) to the MTPLL local network interface (254).
