Signaling
After the physical layer has been tested when provisioning or troubleshooting T1 voice trunks, it is also necessary to
test the transmission and signaling performance of the circuit. This testing verifies the ability of a switch or PBX to
handle incoming calls and ensures switch-to-switch communications. By placing, receiving, or monitoring voice calls,
connectivity can be verified. The 2209 captures and displays digits, signaling events, and signaling bits to provide a more
detailed level of analysis.
The 2209 also simultaneously displays physical layer results so comprehensive testing of the voice trunk can be
completed in a matter of minutes. The 2209 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
