5-40 Interface Parameters Menu
• Main Link Local Analog Loopback – In this mode the data transmitted from
FCD-IPM to the T1 line is sent back to the receive path instead of the received
data from the T1 line. The loopback is shown in Figure 5-48.

• Sublink Local Analog Loopback (for FCD-IPM with a sublink) – In this mode
the data transmitted from FCD-IPM to the sub T1 line is sent back to the
receive path instead of the received data from the sub T1 line. The loopback is
shown in Figure 5-49.

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 T1
• Tone injection to the T1 – a 1 kHz signal is injected into the receive voice
port path, replacing any receive signal from T1, and injected into the T1
transmit path, replacing any transmit signal to T1
• Remote port loopback – the voice port signal which is received from T1 is
transmitted back to T1.
