1.5 Device and Network Security
If this radio network equipment is used for mission-critical applications, it
is important to be able to ensure security and continuity of operation. For
IP-network-connected equipment, it is also important to ensure that this
equipment is not a means of compromising other equipment in the network.
All network elements should be physically secured, where possible. This
includes the use of locked cabinets and locked rooms. Seals on connectors
can also provide a visual indication of unauthorized tampering.
Tait recommends that all network and audio connectors should be sealed
with the stick-on type of seal. The seal should reveal if any of the
connectors have been unplugged, or if any unauthorized equipment has
been plugged in.
The seals should be difficult to remove without breaking, and should bridge
between the cable and equipment side (plug and socket) of the connection.
Seals should cover any unused network or audio sockets. This includes the
Ethernet connector on any adaptor front panels, any spare switch ports, and
the console port on the router and switch.
The seals should be difficult to reproduce. A sticker initialed or signed by
the technician should satisfy this.
Seals must be replaced if they need to be disturbed during maintenance.

Warning Risk of missing calls! Switching between Internal Bat-
tery and EXTERNAL AC/DC, BATTERY ISOLATE will likely
cause the transportable base station to restart!
When the switch is set to Internal Battery, the transportable base sta-
tion runs from the internal battery only.
When the switch is set to EXTERNAL AC/DC, BATTERY ISOLATE,
the internal battery is disconnected from all circuitry in the transportable
base station. In this situation, all the circuits in the transportable base
station, including the repeater, can only run from an external DC or AC
supply.
When connected to a mains lead (AC supply), the repeater will run and
charge the battery if the battery switch is set to EXTERNAL AC/DC.
