“Signaling that occurs between switches (such as private branch exchanges (PBX), local exchange carrier and interexchange carrier) in telephone networks is sent either within the voice traffic (in-band signaling) or on a separate dedicated signaling channel (out of band signaling). The Channel Associated Signaling (CAS) is an in band method to set up and tear down calls. This supervisory signaling is carried as 'on-hook' and 'off-hook.' The addressing is carried as DTMF (Dual Tone Multi Frequency) or as MF (Multi Frequency). This form of signaling is still used to route calls on the public switched telephone network including subscriber lines like 2-wire local loops, on trunks between central offices, and on access trunks such as PBXs,” said Vijay Kulkarni, CEO of GL Communications.
He further added, “GL’s CAS and SS1 legacy protocol test solution supports simulation and analysis of signaling and voice communications interface between the National Airspace System (NAS) Voice System (NVS) and the legacy NAS voice switches, utilizing Ground to Ground (G/G) trunks that support analog interphone call processing.”
In addition, “GL's T1/E1 Cards and USB units provide T1 and VF I/O jacks through which one can monitor or inject audio signals from or onto a designated T1 timeslot, or VF line. The T1/E1 hardware test platform along with analyzer and emulator supporting legacy protocols can generate selective SS-1/ SS-4 signaling, voice call signaling, 2-wire call, single frequency signaling, MFC-R2 analog, E and M signaling types of signaling and voice being carried over communication channel and can analyze these signals in real time.”
