Session 1 – Enhancing Employee
Productivity
• Conferencing
– (Audio Bridge, Web Collaboration, Video)
• Messaging
– (Find Me ~ Follow Me ~ Notify Me, Speech Access, Outlook Client
for Voice Mail and Fax)
• Telephony
– (Touch Screen Phone, IP Phone Applications, Microsoft Outlook
Access, Broadcast Feature)
• Mobility
– (Softphone - Desktop & Cell Phone Client, EC500, Browser-based
Communications Portal)
• Microsoft Integration
– (Office Communicator)
How many DCP phones has Avaya
introduced in the last 3 years?
Session 2 – Four Levels of
Convergence
• Why are we still talking about Convergence?
• The Four Levels

Model 0 – No Convergence
Model 1 – Converge at the Core
Model 2 – Converge at the Edge
Model 3 – Converge at the Desktop

Why are we still talking about
Convergence?
• Move from Network-Centric ~ OrganizationCentric ~ User-Centric Communications
• Avaya’s SIP e-IMS Architecture
• Expanded Integrations/Interactions - Presence
• Enablement to
Enterprise Applications
• Massive Scalability
• Application Sequencing
Model 0 – No Convergence
Model 0 – No Convergence
• Plus
– Most Secure, Highest Reliability. Events and Configuration
Changes in the Data Network are isolated from the VoIP network,
Including the WAN
– Lower requirements for PoE ports. Most Data switches can be
10/100/1000 without PoE while voice switches can be 10/100 with
PoE
– Gig IP Phones are not required to support Data Devices
– Administration is easier with this model
– Easiest model to trouble shoot voice problems
• Minus
– Higher Edge Switch Cost, more Equipment required to support
Switches dedicated to Voice and to Data
– Dual Wiring runs required to each desktop (one for voice, one for
data)
– Higher WAN cost (requires 2 Networks)
Model 1 – Converge at the Core
Model 1 – Converge at the Core
• Plus

Changes in the Data Network are isolated from the VoIP network
– Lower requirements for PoE ports. Most Data switches can be
10/100/1000 without PoE while voice switches can be 10/100 with
PoE
– Gig IP Phones are not required to support Data Devices
– Administration is easier with this model
– Easiest model to trouble shoot voice problems
• Minus
– Higher Edge Switch Cost, more Equipment required to support
Switches dedicated to Voice and to Data
– Dual Wiring runs required to each desktop (one for voice, one for
data)
Model 2 – Converge at the Edge
Model 2 – Converge at the Edge
• Plus
– Equipment requirements may be less than Model 1. Edge switch port
utilization is better as VoIP and Data Devices may be mixed on the same
switch
– Gig IP Phones are not required to support Gig Data Devices because Data
Devices are directly connected to switch ports
– A good model for offices not large enough to justify dedicated VoIP and
Data Switches
• Minus
– More Switch Administration Required than Model 1
– All Edge Switches are typically 10/100/1000 with PoE although IP Phones
only require 10/100 ports with PoE
– All Equipment must support QoS
– A Switch failure or mis-configuration effects both voice and data
– Trouble Shooting voice problems - more difficult
– Dual Wiring runs required to each desktop (one for voice, one for data)
Model 3 – Converge at the Desktop
Model 3 –Converge at Desktop
• Plus
– Less Equipment is Required for this model as VoIP and Data may
share a switch port, maximizing port utilization
– Less Wiring Required as a single wiring run to each desktop can be
used for Voice and Data
• Minus
– Higher Administration Requirement
– Gig IP Phones (higher cost) are required to support Gig Data
Devices connected to phones
– All Edge Switch ports must be PoE and 10/100/1000 to support a
mix with Gig Ethernet Devices
– All Equipment must support QoS
– A Switch failure or mis-configuration affects both voice and data
– A IP Phone problem could affect the attached PC
– Trouble Shooting voice problems - most difficult
Importance of a Sound QoS Design
and Implementation
• Prioritization of real time protocols
– Regardless of available bandwidth
• Low Latency
– < 150ms one way (ITU-T Recommendation)
• Low Jitter
– Variance between packets
– Dynamic Jitter Buffers can help
• Low Packet Loss
– < 1% to 3% - It is Subjective to the application
Why QoS is so Important
• What could happen if packets are simply
played as they arrived—out of order?
Transmitted:
I wish you were here, the weather is beautiful.
Received:
The weather is here, I wish you were beautiful.
Why QoS is so Important
• The problem with excessive packet loss for
real time protocols—dropped packets.
Transmitted:
Received:
I think, therefore I am.
I think I am.
On what manufacturer’s Ethernet
switches does Avaya VoIP operate?
Thank You!
