IP networking – The past few years

Deployment factors – The good and the bad of convergence

Applications and their roles: now and future

Converged IP networking – The next few years

Agenda

IP Networking – Where we’ve been the past few years

VoIP\Network replacement began in 2000

Complete network overhaul due to lack of vendor support

Nortel Succession 1000e v4.x Pure IP Phone switch – One enterprise, One switch, One network

Over 1,400 IP telephony devices currently in use

Targeted deployment based on renovation plans

Redundant IP Telephone switch

Analog and digital ‘IP media’ gateways to IP phone network

Targeted TDM to IP-based conversion of +/- 500 devices per year

Our customers were asking…

Improved access time to mission critical applications

Shorten time to contact critical-path personnel

Streamline patient-caregiver communications

Improve overall response-time for patients needs

Seamless access whenever possible on wired and wireless – same ‘look and feel’ wherever possible

Minimize number of ‘clicks’ necessary to authenticate

Ability to utilize ‘converged applications’ to assist in managing time\resources

Simple, multi-functional mobile devices

IP Networking – Why we’ve done this the past few years

Predictive network management – IP phones offer greater flexibility (multiple applications on a single device), embedded management functions and ease of implementation than non-intelligent devices

Improve staff productivity – Due to the implementation of WLAN roaming with IP phones, messaging, presence and desktop-based productivity applications

Can you hear me now? – Provide technology (VoWLAN, P/C clients, RIM (Blackberry), etc) to assist clinical and non-clinical staff in breaking down communications barriers and build long-term commitment to clinical partnering and process improvement

Investment protection – Maximize assets and currently deployed technology to keep up-to-date with converged voice/data/video based medical solutions

Deployment Factors

Network assessment – Make sure your network is functioning properly prior to running any type of converged applications

Good candidates – Select areas where new wiring is a must, or where it would be best served by a single infrastructure

E911 issues – Tracking down roaming and mobile IP phone users is not as easy as it seems and may require a login process

Cost savings – Adding an IP phone device or a soft phone license with headset to an existing P/C will be more productive, as well as save wiring costs.

Support staff training – Train your network staff to deploy phones or your phone staff to deploy networks?

Deployment Factors

End user familiarity – It takes very little time to in-service staff on the features of an IP device

The mystique of ‘a network phone’ – The network phone can be intimidating to all staff – But shouldn’t

New applications, new concerns – Converged applications need to be treated as you would any other productivity deployment

Workload concerns – With larger deployments where a complete cutover is next to impossible, increased complication and workload will ensue due to the parallel requirement

Single administration and infrastructure – Providing one network to keep up with instead of many

Deployment Factors

Network Management to the desktop– New IP devices offer real-time statistics on their voice quality

Network Management of the enterprise – Core network management vendors have developed Voice over monitoring tools

Wireless networking – Treated as a valued extension of your wired network, only with extra concerns for bandwidth management

Wireless productivity – Immeasurable gains when wireless devices are paired with existing systems to streamline processes

Converged Applications

Softphone application via Nortel’s MCS5100/i2050

– Freedom of movement – Bluetooth headsets

– Take your extension with you – office, home, & road

– Presence indicator lets ‘the world’ know you’re online

– Your counterparts can tell your current ‘status’

– Choose the device (soft or hard) to be communicated with

– You choose the time you wish to be ‘online’

Instant Messaging– Simultaneous use of softphone and IM means you can get more

done in less time

– Becoming a standard: will be used as much as e-mail

– SIP based softphone client can connect to many different PBX’s

– Multiple device capable, not just softphone or P/C application

Converged Networking – Where we’ll be going the next few years

Push failsafe technology to the edge – UPS and power feeds, redundant Power-over-Ethernet devices, HVAC, Fiber infrastructure

Deploy ‘media gateways’ at the edge – These devices will continue to assist in infrastructure consolidation

Switch to ‘virtual-trunking’ capabilities for your inbound and outbound telephony – Regional service providers will offer this technology in the near future, greatly assisting Disaster Recovery efforts

Video over IP and Wi-Fi will catch up quickly – Recent advances in technology and vendor relationships will net an affordable deliverable in this space

Next generation wireless – These ‘super-devices’ are hitting the market, offering Cellular, Wi-Fi, Bluetooth, Pocket PC, and instant messaging interfaces to existing applications

Considerations for CIPN - Converged IP Networking

New WLAN and softphone applications are coming out every month, each offering more and more productivity at a lower cost

New Wi-Fi technology will continue to revolutionize the environment we work in

Combination devices\applications seem to be more prevalent this year, this will greatly assist in the ‘one-device for all’ scenario

Newer IP telephony switches should offer higher density and an increased number of ‘media gateway’ interfaces in and out of the IP network

SIP and SSL based VPN technology are opening up the traveling and work-from-home environments

High-availability, zero-downtime LAN switches recently available will have a big impact on overall deployment of converged applications in 24x7
