Integrate Backup Power into VoIP Networks
Voice over IP (VoIP) is exploding in popularity as an application for business
data networks. VoIP promises to consolidate a company's data and
telecommunications infrastructure as well as its support resources. As a
result, a company can lower its hardware and service costs while raising
productivity through the use of more elaborate and customizable telephony
applications.
Unfortunately, there are serious limitations inherent to the data networks
that are increasingly called upon to support VoIP. The primary limitation is
power availability. Before moving voice traffic from traditional circuit-
switched public phone systems to private data network connections, one
must consider a public phone system's unique attribute—battery support. In
order to deliver extremely high availability for such vital services as
emergency 911 support in the event of extended power outages, public
phone systems are connected to massive battery arrays.
While most data networks have some type of backup support during power
outages (provided by UPS Systems and/or generators), the backup runtime
is generally much less than the 4 to 8 hours of backup that is typically
provided for public phone systems. Because of this shortcoming, VoIP
applications generally require an increase in the UPS System-supported
power capacity (e.g. more or larger UPS Systems). Increased UPS System
capacity provides power for network-dependent phones and increases
overall backup runtime to ensure that normal telephone operation (including
911 service) remains available in the event of an extended power outage.
Reflecting on important lessons learned during its own transition to IP
telephony, Cisco provides several best-practice recommendations. One of
the most important recommendations is installing a UPS System to
guarantee availability:
“Plan Your Power: When an IP network carries voice,
reliability is essential. In case of an emergency,
people need to summon assistance by dialing 911.
When using inline power to switches and routers, make
sure they are connected to an uninterruptible power
supply [UPS System] to guarantee dial tone if the
power should go out.”

Consider the Diverse Needs of VoIP Network Equipment
Before selecting a UPS System to ensure 100% availability of IP telephony
systems, it's important to consider the unique requirements of VoIP network
equipment. Network designs hosting VoIP applications will vary widely from
business to business due to a number of variables, including the scale of
the network and the variety of legacy equipment involved. However, three
devices are common to all networks:
Client Devices (phones, PC-based soft phones, etc.)
During the transition to IP telephony, these devices will either (a) derive
their power from the network cable via a Power over Ethernet (PoE)
connection scheme, or (b) plug into a local AC source.
If they plug into a local AC source, they must be protected by a UPS
System. Often a desktop UPS not only safeguards phone service, but also
guarantees file integrity for associated PC users.
Networking Devices (switches, routers, etc.)
During the transition to IP telephony, port capacity on the network and in
wiring closets will increase to accommodate additional devices (phones)
connected to the network. Increased port capacity will increase the power
requirements placed on your UPS System, either reducing runtime or
overloading the UPS. Note that if a networking device also supplies Power
over Ethernet, the aggregate load of all client devices will also be borne by
the networking device's UPS System.
Generally, an existing UPS will be inadequate to (a) power the increased
load [watts] and (b) power the load for an acceptable length of time. Five to
fifteen minutes of runtime provided to gracefully shut down the typical data
network is inadequate for IP telephony users who expect phone service to
continue for HOURS, not minutes.
Call Processing Devices (servers and related storage systems)
During the transition to IP telephony, dedicated servers are typically added
to drive voice and messaging applications, while storage systems are
required for voicemail and other messaging applications. Similar to the
increased burden placed on networking devices, call processing devices will
experience increased loads and will require increased runtime.

Select a UPS System which Provides the Highest Availability, Resiliency
and Manageability
When selecting a UPS System, the most obvious criterion to consider is
whether a UPS System has enough capacity (VA/watts) to power equipment
while having enough battery capacity to operate during a power outage for
your required duration. Specific Tripp Lite UPS System recommendations are
listed at the end of this document. Often overlooked during the selection
process, however, are more subtle, yet critical, criteria that should be
considered, including availability, resiliency to power anomalies and
manageability.
1. Availability
Availability hinges on three considerations: the VoIP equipment's power
supply configuration, the UPS System's battery configuration and the UPS
System's power electronics topology.
A. VoIP Equipment Power Supply Configuration
Many switches and routers are equipped with redundant power supply
capability. If one power supply fails, a second power supply steps in
and powers the device. Redundant power supply configurations are
strongly recommended to ensure continuous system availability.
Whether one or two power supplies are deployed, the equipment can
draw power from one of three sources: directly from facility power alone
(for simplicity's sake we will use the term “wall” to describe this
source), from a single UPS System or from multiple UPS Systems.
The following tables detail a switch's operational status, from a power
perspective, in both redundant and combined (non-redundant) modes.
The tables detail switch status under a variety of operational scenarios,
including power supply failure, utility failure and UPS System failure.
Note: Larger switches often have the capability to be alternatively configured to operate in
a combined (non-redundant) configuration. In combined mode, two power supplies'
capacities will be summed. A true doubling is not generally achieved. A factor of 1.67x is
typical. In combined mode, there is no redundancy. Should a power supply fail, the
available power is generally reduced to the capacity of a single power supply.

B. UPS System Battery Configuration
UPS System availability, and therefore VoIP system availability, is most
critically dependent upon the capacity of the UPS System's battery
configuration. The number of UPS System batteries, both internal and
external, determines the amount of runtime that is provided during a
power outage. As mentioned previously, the runtime must fit the
application. Most existing data networks are unlikely to provide reserve
runtime power comparable to the public switched phone network. One
has to determine a runtime estimate of what is adequate or desirable
specifically for a VoIP application. Most users conclude that hours, not
minutes, of backup runtime are required to maintain voice operations.
Like any estimate, a runtime estimate will be imperfect and will also be
impacted by future capacity requirements (such as the addition of more
phones). Therefore, it is critical that the selected UPS System can
accommodate external battery packs to increase runtime as needs
increase, or maintain runtime in a growing phone environment.
Runtime scalability with external battery packs also yields the ability to
hot swap battery packs at the end of their useful life without a service
interruption. Similar hot swap battery replacement is also the norm for
the UPS System's internal batteries.
C. UPS System Power Electronics
If a UPS System's power electronics fail during a utility power outage,
the supported IP telephony system will obviously crash. If the UPS
System failure occurs while utility power is present, however, different
UPS power electronics topologies can impact IP telephony system
availability in different ways.
On-Line UPS System with Internal Bypass
With power present, an internal power electronics fault in an on-line
UPS System will result in the load automatically being powered by a
bypass path inside the UPS. As long as utility power remains present,
the UPS will continue to power the connected IP telephony system
without interruption and will continue to condition the power against
basic power anomalies. In the event of a power outage, the system
will crash.
Upon development of a bypass condition, a service interruption needs
to be planned to replace the UPS System.

With power present, a battery system failure will not cause a system
interruption. As long as utility power remains present, the UPS
System will continue to power the connected IP telephony system
without interruption and will continue to condition the power against
most power anomalies. In the event of a power outage, the system
will crash.
In the event of a battery system failure, the internal batteries of the
UPS System and/or the external battery packs can be replaced
without a service interruption.
On-Line UPS System with Internal Bypass and External
Maintenance Bypass
With power present, an internal power electronics fault will result in
the load automatically being powered by a bypass path inside the
UPS. As long as utility power remains present, the UPS will continue
to power the connected VoIP system without interruption and will
continue to condition the power against basic power anomalies. In
the event of a power outage, the system will crash.
In the event of a bypass condition, the power electronics module of
the UPS should be replaced. This can be performed while the system
remains in service, as the input and output power connections are
physically and electrically separated from the power module itself.
This functionality is available presently in Tripp Lite's 5-16KVA
SmartOnline™ Hot-Swappable Modular UPS Systems.
With power present, a battery system failure will not cause a system
interruption. As long as utility power remains present, the UPS
System will continue to power the connected IP telephony system
without interruption and will continue to condition the power against
most power anomalies. In the event of a power outage, the system
will crash.
In the event of a battery system failure, the internal batteries of the
UPS System and/or the external battery packs can be replaced
without a service interruption.
Line-Interactive UPS System
With power present, an internal power electronics fault can result in
the load crashing. As the operational requirements of a line-interactive
UPS System are very simple when power is present, this is extremely
rare. Line-interactive power electronics failures are normally only
detected when the power fails and the UPS attempts to power the load
from its battery-driven inverter.

In the event of a power electronics failure, a service interruption
needs to be planned to replace the UPS System.
With power present, a battery system failure will not cause a system
interruption. As long as utility power remains present, the UPS
System will continue to power the connected IP telephony system
without interruption and will continue to condition the power against
many power anomalies. In the event of a power outage, the system
will crash.
In the event of a battery system failure, the internal batteries of the
UPS System and/or the external battery packs can be replaced
without a service interruption.
2. Resiliency to Power Anomalies
The fundamental outcome one hopes for in adding UPS System support to
a network is to enhance system availability. But an additional concept—
resiliency—is very important as well. UPS System resiliency reflects the
ability to respond positively to a number of operating variables.
A. Voltage Variation
Currently, one of the most popular UPS System topologies for VoIP is
provided by on-line UPS Systems. An on-line UPS System can deliver
perfect power even if it encounters a very wide range of input voltages.
The on-line UPS does this without relying on its battery reserves, leaving it
well prepared to respond to a power outage. Because of its continuous
AC-DC-AC conversion process, during an outage an on-line UPS System
will also exhibit zero transfer time between power failure detection and
power delivery to your equipment. On-line UPS Systems are widely
acknowledged to be compatible with all types of VoIP devices.
In many networks with distributed UPS Systems, line-interactive UPS
Systems are widely deployed. If input voltage levels are below the line-
interactive UPS System's automatic correction capability, the UPS will
switch to battery to maintain acceptable output voltage. In areas with
chronic extreme brownouts, this frequent switching to battery can reduce
reserve power as well as shorten battery service life—putting critical
systems at risk in an outage.
While the transfer time of a line-interactive UPS System (several
milliseconds) is extremely fast, this short delay has been theorized as the
cause of packet losses, or even system shutdown in some applications.
Depending on your power environment and the sensitivity of your IP
telephony components, a line-interactive UPS System may or may not be

adequate. Generally, line-interactive UPS Systems do not pose a problem.
This is the subject of some debate and is generally presented as a major
issue by vendors biased towards selling online UPS Systems.
Line-interactive UPS Systems do tend to cost less than on-line UPS
Systems and operate with higher efficiency, reducing electrical costs.
In theory, an on-line UPS System battery should be used less frequently
due to input voltage variation, and will therefore last longer. This advantage
will manifest itself more as the frequency of input voltage variation
increases.
B. Harmonic Distortion
Only an on-line UPS System will address input harmonic distortion.
Because an on-line UPS System deconstructs and reconstructs the input
power, it can deliver distortion-free power. A line-interactive UPS System
will pass through input waveform distortions. Harmonic distortion tends to
be an elusive “gremlin” issue when it affects connected loads.
C. Transient Spikes (or “Surges”)
Both line-interactive and on-line UPS Systems address sudden increases in
voltage.
D. Electromagnetic Interference
While both line-interactive and on-line UPS Systems address these
phenomena, an on-line UPS typically offers far superior filtering capability.
3. Manageability
VoIP system availability is closely tied to UPS System manageability. To
ensure continuous availability, UPS Systems must be incorporated as an
integral part of a sound hardware management scheme. UPS Systems are
extremely manageable and responsive, communicating their status
automatically and triggering application shutdowns prior to battery
exhaustion in the event of a power outage or extreme voltage variation.
There are various methods to communicate with UPS systems, including
SNMP, Web, network software and direct connection. While most users
choose SNMP/Web accessory cards installed inside UPS Systems for
communication, the most essential requirement is to deploy and use some
method of communication. Without a management application running for
your UPS Systems, the day will come when the UPS batteries fail and your
system fails as your power fails. Simple management steps taken at
installation can save significant problems later.

Alerts available from most UPS Systems and network cards include:
• Voltage levels
• Current levels
• Temperature levels
• Humidity levels
• Dry contacts for fire, water, security, etc.
• Battery capacity
• Battery failure
Commands from the administrator to most UPS Systems include:
• Reboot system
• Reboot outlet(s)
• Shut down system
• Shut down outlet(s)
• Run inverter/battery test
Tripp Lite presents a uniquely simple management scheme for VoIP
UPS System hardware. Whether management is through an IP-addressed
SNMP/Web accessory card or PowerAlert Software, Tripp Lite provides
administrators with a single JAVA-based user interface. The commonality
within this design approach makes it ideal for managing VoIP applications
of all scales across multiple OS platforms.
During a power failure, Tripp Lite's PowerAlert Software ensures a smooth
and customizable shutdown of call processing and voice messaging
applications as well as the underlying operating system.
As a unique feature, Tripp Lite's PowerAlert Software and network accessory
card (SNMPWEBCARD) are designed to accommodate multiple power
supply and UPS System hardware deployments. With a single IP address
assigned to the SNMPWEBCARD (or a single PC/Server running PowerAlert)
users can manage multiple redundant UPS Systems working in tandem to
provide optimal power to the IP telephony system's single or multiple power
supplies.
Alternative UPS System manufacturers require each UPS to be managed
individually. With these UPS Systems, there is no easy way to manage their
redundant operation without expensive and space-consuming external
power-switching accessories.

Tripp Lite's PowerAlert Software, version 12.5—which is part of an
integrated VoIP power solution that includes a Tripp Lite UPS System—has
met the Cisco Technology Developer Partner Program test criteria for
interoperability with Media Convergence Servers running CallManager,
versions 3.3(4) and 4.0(2). Through participation in the Cisco Technology
Developer Partner Program, Tripp Lite's integrated VoIP solution provides
continuous IP telephony availability to enterprise customers.
As an additional management tool, PowerAlert also offers centralized
management within a NMS-style, management tool.
Another unique manageability product provided by Tripp Lite is its Watchdog
Service Monitoring/Rebooting Software. Tripp Lite's Watchdog Software
ensures maximum availability, eliminating call processing server downtime
by automatically rebooting locked-up or poorly performing system service
applications. If a locked service cannot be rebooted, Watchdog Software
will automatically direct PowerAlert Software to reboot the server. If the
server is non-responsive, the UPS System will power down and then restart
the attached devices.
Recommended Tripp Lite UPS Systems for VoIP Applications
Establishing an adequate power protection infrastructure is essential. Again, three
areas of demand must be addressed: Client, Network and Call Processing.
Client Devices (phones, PC-based soft phones, etc.)

Networking Devices (switches, routers, etc.)
Networking hardware will typically drive the most significant changes to your
existing power infrastructure. With requirements spanning buildings and
remote wiring closets, existing facility-wide backup plans are often
impractical or unable to address the requirements of mid-size and large
switches. Focused UPS System additions with extended runtime battery
configurations more efficiently add the high level of availability that VoIP
users demand.
Tripp Lite maintains interactive sizing and configuration resources at
www.tripplite.com/selector. We also welcome your contact with our
technical staff via [email protected] or [phone].
Basic sizing is as simple as…
1. Determining the power consumption of your equipment:
Volts x Amps = VA.
2. Ensuring that the UPS System has enough power and outlets to
accommodate your equipment.
Many larger routers and switches accommodate multiple power supplies.
Once you have identified your power supply type and quantity, use the
following details to find a specific UPS System solution for your needs:
1. Identify power supply configuration
a. Single power supply or two supplies operating in redundant mode
b. Dual (combined) mode
2. Determine UPS System protection scheme
a. Single UPS System for both power supplies
b. Single UPS System per power supply (higher availability)
3. Estimate desired runtime during power outage
