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

Selecting the Appropriate Sized PoE Midspan and UPS
Example: Switching closet with 96 IP lines (4x 24-ports switches) providing connectivity to 48 users, each with a PC and a PoE-powered IP phone.
Equipment Rated input Power
in Watts
X Number of stacked switches
X 1/Power Factor = Power in VA
24-port switches without PoE support 150 X 4 X 1.10 = 660
24-port switches with PoE support 400 X 0 X 1.10 = 0
Midspan units 220 X 2 X 1.05 = 462
Other equipment 0 X 0 X 1.43 = 0

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.
