4. Today’s Enterprise Operational Landscape
Constantly changing
Business 2.0, UC, Collaboration, not just buzz terms
Enterprises de-centralized, yet focused
New applications to serve customers
New methods to control costs
Constantly changing
Business 2.0, UC, Collaboration, not just buzz terms, they are a fact of business life, even to the point I was at the US ITPX conference where someone announced that UC is passe and has been replaced by collaboration
Enterprises de-centralized, yet focused
with the recent economic slowdown there have been many changes to the operational landscape. Companies and institutions have decentralized but need way for those remote locations to communicate and cooperate (UofH trying to coordinate telecommunications across a number of locations across the island)
New applications to serve customers
as mentioned above UC (unified communications), OCS (Office Communications Server) all trying to offer more services through the same platform. Just look at the success of iPhone, Android and iPad
New methods to control costs
many of these news services are there to restrain costs and one of the prime driving factors in the move to VoIP

5. Today’s Enterprise Telephony Landscape
Massive proprietary legacy infrastructure base
VoIP benefits real: cost savings, productivity, application integration
New choices, more flexibility
Migration to VoIP fast, but could be faster
Massive proprietary legacy infrastructure base
large number of companies, institutions with existing PBX or Centrex infrastructure and all trying to determine
VoIP benefits real: cost savings, productivity, application integration
New choices, more flexibility
everyday there appears to be new offerings and new sub-offerings for the telecom industry especially as the industry changes – look at what has happened since Nortel collapsed.
Migration to VoIP fast, but could be faster
what is holding up the move.

6. Enterprise Telephony Priorities
Operational/Total Cost Reduction
Reliability/Availability/Security
Scalability
Standards
System Integration/Consolidation
Operational/Total Cost Reduction
need to reduce the operational costs, line, maintenance building
Reliability/Availability/Security
issues of QoS, what equipment can be supported in the future, security of information
Scalability
can our system be scaled any more, if not , what are the alternatives
Standards
what are the forthcoming standards and how do they affect future of telephony
System Integration/Consolidation
how do I integrate multiple systems and diverse locations.

7. Objections to Migrating to VoIP
Heavy Investment in Legacy Equipment and Cabling
End User Comfort with Existing Telephony Setup
Investment to rewire with Category 5/6 Data Cable
Power over Ethernet (PoE) Switch Required
Disruption of work environment while cabling and PoE installed
Heavy Investment in Legacy Equipment and Cabling
End User Comfort with Existing Telephony Setup
Handsets still working well and cabling difficult to replace
Investment to rewire with Category 5/6 Data Cable
how to handle historical, rental/leased buildings, who benefits when you move
some institutions can only do as part of a renovation schedule that can extend out years
Power over Ethernet (PoE) Switch Required
up to $40 per station
special rooms required
Disruption of work environment while cabling and PoE installed
how do you re-cable a hospital without impacting surgery schedules for example

8. Objections to Migrating to VoIP - continued
Investment cost of new IP phones
Disruption of work flow as employees require training on new functionality of IP phones
Lack of confidence in the quality of VoIP
Anxiety of stepping into the unknown
Investment cost of new IP phones
start at $100 and move on up. To compete with some of the legacy handsets could be looking at more than $300 for the equivalent IP phone
Disruption of work flow as employees require training on new functionality of IP phones
Have to train the employees in how to use another new piece of equipment. Its bad enough computers, mobile phones, are changing all of the time
Lack of confidence in the quality of VoIP
How confident are people in the QoS issue
Many times it is far superior to PSTN however as it is new QoS issues are heard about with more frequency
Anxiety of stepping into the unknown

14. Duo County Telephone Centrex VoIP Migration Issues
Goal
Seamless transition as possible from the DMS100 platform to their MetaSwitch hosted platform
- Made decision to switch to MetaSwitch in 2007 to allow for more flexibility and features in their voice offerings;
- Began a staggered migration of customers to the Metaswitch in 2008, and completed that in mid- 2009,

15. Duo County Telephone Centrex VoIP Migration Issues
Problems Faced
To switch to IP phones - cumbersome and labor-intensive
new cable runs in many areas;
additional AC power requirements for the phones;
significant learning curve and unavoidable service interruptions for the customer.

16. Duo County Telephone Centrex VoIP Migration Issues
Solution – Existing Phones with TVA Interface to Metaswitch platform:
Duo County can work in active businesses without affecting their work routine;
One day versus three to four days to migrate
Handset retention was a major positive factor;
directly affects the time spent training the customer after the migration.
Can mount these units without having to do any rewiring, either of phone lines or providing extra AC power.
Since the Portico TVA unit has a working range of 3000 feet, and many of their Centrex users were located in the downtown area, those customers could be served from a central office, allowing Portico TVA units to be mounted at Duo County’s central office, allowing them to utilize their existing private IP network. This had a bonus affect that they could use their existing copper pairs from our central office, and complete the migration without even going to the customer premise. At other locations, they simply mounted the unit where the existing demarc blocks were located, making the migration very simple.
After working closely with the technical team at Citel, we were able to hold customer changes in phone operation to a minimum, and customers seemed to appreciate that. For all the small changes that they had to make, they were pleased to gain some advantages, such as a better Caller ID display, easier transfer of calls, and no longer needing to push a direct line key for an incoming call.

17. Duo County Telephone Centrex VoIP Migration Issues
“When we first started our migration process, we considered the Portico TVA a viable option to the IP Phone. We quickly realized that is was more than an option, it was the solution.” Kerry Flatt, Duo County

18. Citel’s Portico™ TVA™ Solution
SIP media adapter designed to convert existing
P-Phone, analog and digital proprietary PBX telephone sets into “SIP Endpoints”

19. Current TDM Customer Scenario
Service Provider
PSTN
Existing cabling
25 Pair
Amphenol
Nortel BCM exchange is the example here.
Using e.g. ISDN trunk to PSTN

20. Premise Based IP PBX Offering with Citel TVA

Amphenol
Telephone VoIP Adapter
PBX (BCM) is replaced here with a Telephone VoIP Adapter and IP PBX. In this example could be Asterisk… or whatever you go for.
ISDN trunk lines have been replaced with SIP trunks over IP to a SIP trunk provider.
Note. that the ISDN trunks could have been retained on the IP PBX e.g. with an Asterisk trunk card, or say if the PBX was IP Office with IP Office trunk ports. That would be a part stage to VoIP – as the user is missing out of the savings on moving to SIP trunks.

21. Hosted IP PBX Offering with Citel TVA

And here is an alternate scenario, where the old (BCM in the example) PBX is removed and replaced with a TVA, but instead of an IP PBX a hosted VoIP service is taken, the TVA makes the SIP registration direct to the hosted provider.
If the hosted provider, and TVA local services, gives you the features required.

25. Portico™ Telephone VoIP Adapter (TVA™) Compatible Handset Types – TVA12D & TVA24D
Here’s the first of 2 slides on the digital handsets supported at the moment.
Version coming out in next few weeks – includes initial Alcatel support, and some other additional phones.

26. Portico™ Telephone VoIP Adapter (TVA™) Compatible Handset Types – TVA12D & TVA24D
The TVA is configured by the Setup Wizard to support the phones of a particular PBX type – as each PBX tends to operate at different voltages.
But any supported phone within the class can then be connected
The flexibility of the TVA to drive so many phone types has led Florida department of Health as part of its Disaster Recovery Plan to deploy TVA it in its Mobile Communication Vehicles so at any installation where communications have failed they intercept the phone wiring at the rj21 plug, drop in their powered TVA, and bring the phone system straight back up for emergency use.

27. Portico™ Telephone VoIP Adapter (TVA™) Compatible Handset Types – TVA12P & TVA24P
Here are the P-Phone Centrex handsets supported by the P-Phone /Analog TVAs: These are Nortel P-Phones – from DMS100 exchanges – in UK BT Featurenet
Also supported are analog Centrex handsets, such as Featureline.
Citel have this week published a new case study on Duo County Telephone – a Kentucky based co-operative that has nearly completed a major migration of P-Phone Centrex handsets to VoIP using TVA, and the Metaswitch platform.

Two key interfaces are:
3. LAN – network connection to world of VoIP
6. Telephony interface – an RJ21 connector to the phones.

33. Cabling Requirements
Cabling to handsets requires only one pair of wires
Cabling is Polarity Sensitive for Meridian 1 phones
Cat 3 (or higher) station cable is recommended, maximum loop length is 1600 ft or 500m
Existing PBX/station wiring may be re-used
Read it out.
Cat 3 normally what is installed already.
If a few outlying phone are too far away,
consider using some IP phones.
Or position TVAs around the installation as required.

34. Telephone Station Wiring
Punch down blocks
25 pair cable
Legacy phones
Station cables
cross-wiring
Female RJ21 Connector
Of course in many cases the Amphenol (RJ21) connector can be taken off the legacy PBX and moved straight onto the TVA – no re-patching at all.
Also in commissioning it is possible to install and do a weekend or overnight test run – and then go back to the legacy PBX until formal changeover.
There is a Citel Case Study for National Sales & Distribution where the installer describes how easy the changeover can be.

35. Getting started – out of the box setup
Simply step thru the Console Setup Wizard, giving:
Unit name
Enable all ports
To setup phone class – from PBX type
Country – default codec
Static IP or DHCP
The Console is available on the serial port
e.g. hyperterminal
The Setup Wizard runs automatically first time.
Hyperterminal 9600, 8 bits no parity.
After initial config, serial console is for maintenance/support if necessary
Use USB to serial adapter.
So get the IP address from console, and….
From then on, configuration is normally via the Web Portal.
