Voice Diagnostic Tools
There are three voice diagnostic tools that are available for FCD-IPM. They can be
set independently for each voice port:
• Tone injection to the voice port – a 1 kHz signal is injected into the receive
voice port path, replacing any receive signal from E1
• Tone injection to the E1 – a 1 kHz signal is injected into the receive voice
port path, replacing any receive signal from E1, and injected into the E1
transmit path, replacing any transmit signal to E1
• Remote port loopback – the voice port signal which is received from E1 is
transmitted back to E1.
