6. MONITORING DIGITAL PORT AND DIGITAL CHANNEL STATUS
So far the UCM6510 has both digital trunk and data trunk successfully configured. Users should be able to
use it for phone calls and Internet connection. In this example, 10 channels (channel 1 to channel 10) are
used for voice, 13 (channel 11 to channel 23) channels are used for data. While using the digital trunk and
data trunk, users can monitor the connection status via UCM6510 web UI.
 Monitor interface status under web UI->Status->PBX Status.

Connected and working
RED alarm: there is physical wiring problem,
loss of connectivity, or a framing/line-coding
mismatch with the remote switch.
YELLOW alarm: connected but the link is
working only one-way. This means that the
remote switch is not able to maintain sync with
you, or is not receiving your transmission.
The following example scenarios could trigger
YELLOW alarm:
1. The T1 port is connected with J1
connection.
2. Incorrect cable is used.
3. When using E1, one end is using CRC4
