Signaling
After testing the physical layer when provisioning or troubleshooting T1 voice trunks, it is also necessary to test the
transmission and signaling performance of the circuit to verify the ability of a switch or PBX to handle incoming calls
and ensure switch-to-switch communications. By placing, receiving, or monitoring voice calls, connectivity can be
verified. Capture and display of digits, signaling events, and signaling bits provides a more detailed level of analysis.
The 2207 also simultaneously displays physical layer results so comprehensive testing of the voice trunk can be
completed in a matter of minutes. The 2207 provides signaling and voice results such as:
• DP, DTMF, MF digit recognition
• Inter-event/digit delay mesurements
• Event/digit duration measurements
• Speaker/Mircophone or handset functionality for checking voice integrity
• Signaling (ABCD) bits
