Tips - Defining which Type is Optimal
The phone requires external power at all times. An AC wall power adapter (type C)
for powering the phone is the most obvious and immediate means; it is both the easiest
from an installation standpoint and currently the most cost-effective approach to
providing power to the phone. Adding power ports (types A or B) to an existing LAN
can be significantly more costly than the simple AC wall adapter. Nevertheless, the
added convenience of reducing the amount of cables to the desktop, or placing a phone
where power is not readily available from the building power wiring and receptacles,
is a major advantage of using power over the data network. Powering over the LAN
(type A and B or IEEE 802.3AF standard) infrastructure will reduce wiring costs as
equipment manufacturers offer more choices in standalone LAN power hubs and
integrated power/data switches.
Powering the phone over the Ethernet offers the following advantages:
 If the LAN has power backup, voice services can stay online along with data
in the event of a power failure.

Less electrical cabling is required for new buildings, office relocations,
re-configurations, and personnel moves.
 Only one cable needs to be routed to the phone desktop, with power to the
phone being an integral part of the centrally managed IP infrastructure.

Only a single network connection is required to place both the phone and the
desktop PC on the LAN - no ports or power receptacles are necessary.
