Market Opportunity
 Significant VoIP advantages over traditional enterprise
telephony networks
> Reduced carrier circuit charges
> Enhanced applications
– Desktop video conferencing
– Voice-enabled Web sites
> Integrated management systems and strategies
> Increased flexibility for a reduction in overall complexity and
elimination of circuit redundancy

Market Opportunity
 Power over Ethernet Standardization
> IEEE 802.3af
– This standard allows a convenient and cost-effective powering of
the phones (no local desk DC power needed) as well as simple,
centralized power protection of the whole installation directly from
the switch/wiring closet.

IP Telephony Considerations
 Key considerations in the implementation of Power over
Ethernet
> Availability
– Five nines (99.999%) availability
– 5.3 minutes or less of downtime per year
> Simplicity of installation
– Elimination of individual AC sources

Conclusion
 Change in the way we think about powering network components.
 New network applications and devices are adapting to and greatly
benefiting from such technology.
 With the combination of this standard, it is now convenient, easy to
manage and cost-effective to reliably power network devices such
as IP phones, wireless access points, IP-based security devices
and many other devices.
