Advanced signaling capabilities for PCM systems

Statistic screens show traffic The SunSet SDH contains the complete diagnostic tools necessary to install and troubleshoot voice circuits. Its PCM signaling features support MFCR2, SS5, pulse, and DTMF digit analysis and call emulation. This allows you to test signaling in the public networks, as well as the interfaces between the public network and PABXs. Bidirectional monitoring can troubleshoot lines and register signaling problems between two exchanges. Call emulation can be used for installation testing and verification.

Voice Frequency Testing

The SunSet SDH tests digital to analog conversion by inserting and measuring tones (50 to 3950 Hz) on individual channels. You may talk/listen over a channel using the SunSet’s integrated microphone and speaker.

Signaling analysis and noise measurements

Test channel quality with signal-to-noise, C-notch, phosphometric, 3K-flat, and peak coder offset. In-service circuits can easily be tested for signaling errors. The SunSet SDH features digit and CAS analysis. A single screen simultaneously displays the CAS status of all 30 channels in both directions. You can also trigger on specific CAS events or user specified states. Line and register signaling can also be defined with variance from ITU Q.422 and Q.441 standards.

Call emulation

The SunSet SDH can place and receive voice calls to easily verify service and voice path when installing new trunks or PABX equipment. Whether it’s DTMF, MFC-R2, SS5, or pulse, the SunSet SDH can support the wide variety of circuits you encounter. The integrated microphone and speaker (and headphone) check the voice path. A Call Emulator feature allows you to program expected call sequences. Full-duplex drop and insert testing means you can place a call or send a test tone on an in-service circuit.
