Manual for Node AM4
4.2.5. Alarm Forwarding
Alarms can be forwarded from the Node AM to a defined phone number or to the OMC
via the Ethernet port on the UI2 Board (see chapter
4.3.6
) or via an optional modem. This
enables the provider to control and to query the status of the network via packet switched,
circuit switched, or LAN connection. Faults and irregularities can be recognized and
eliminated.
With a modem equipped the Node AM also provides an SMS feature, by which the unit
is able to send out alarm messages as SMS. For further details please contact
CommScope.
4.3. Components
The actual configuration of the individual Node AM4 can be seen in the configuration list,
which is part of the delivery. It is also available as an electronic list accessible via
software.
The following figure shows the layout of a system using single-band RF cards only. If one
or more dual-band cards are equipped the only deviation is a different type of multiband
combiner (see figure 4-3).
