Interoperability Compliance Testing; General Test Approach; Test Results - Avaya RAD IPmux-14 TDMoIP Application Notes

5. Interoperability Compliance Testing

The interoperability compliance testing focused on transporting the T1/E1s utilized for Avaya DS1
Converter Remote Port Network connectivity, over an IP network using the RAD IPmux-14
TDMoIP Gateway device. The testing was performed for transporting four T1s from an Avaya
MCC1 Media Gateway (main PN) at the main site to an Avaya SCC1 Media Gateway (remote PN)
at the remote site. The same tests were repeated for transporting four E1s.

5.1. General Test Approach

The general approach was to validate the execution of maintenance tests for the remote PN and make
a variety of calls over the main PN and remote PN. The test calls included voice calls, data calls
using modems, and fax calls – off net and on-net calls. Synchronization of remote PN with main PN
is critical to the success of this solution and was configured and validated. The main objectives were
to verify that:
• The remote PN is up and working when the DS1 Converter link is established.
• The hardware objects on the remote PN, such as DS1-C facility, tone-clock, fiber-link etc.,
are working properly and can be maintained via Avaya Communication Manager
maintenance test commands.
• Resetting the hardware such as DS1 Converter board or remote port network, or resetting the
Avaya Communication Manager works properly.
• The on-net voice calls (from main PN to remote PN, or remote PN to main PN) and the off-
net voice calls (remote PN to public network via main PN) have good quality and no static or
echo.
• Modem calls from the remote PN to the public network via the main PN are successful.
• On-net and Off-net Fax calls are successful.
• DTMF tones can be transmitted successfully from remote PN to the public network.
• The maximum possible calls over the DS1 Connector complex (over 4 T1s or 4 E1s) can be
established.
• The system operates properly during and after a load test.

5.2. Test Results

All test cases completed successfully. With the appropriate synchronization of main PN and remote
PN, the voice, data and fax calls were successful. The following behavior was observed in one of the
scenarios:
1. DTMF tones are transmitted from remote PN to public network successfully. However, when
the digit keys are pressed and released on the telephone, even after the key is released, the
DTMF tone is heard for another fraction of a second as if it is being echoed.
