Signaling conversion/signaling gateway

Some telecom equipment from overseas can not communicate with the local telecom network. The versatile interfaces of SPAS programmable Switch support the comprehensive standards at lower cost, and help realize the conversion among R2MF, SS7, ISDN PRA, CAS, Access network V5X signaling.
Voice codec may be incompatible when the interface of the input is different from that of the output. Multi-function signal tone board, in this case, can be used to realize the conversion of the voice codec. An example is the voice conversion between E1 A LAW and T1 U LAW.
