Portico™ Telephone VoIP Adapter (TVA™)

Citel originally manufactured the P-phone version of its Portico™ TVA™ (“TVA-P”) as a premise-based device, enabling carriers to replace their Centrex system to deliver hosted / cloud or premise-based VoIP services and applications to Centrex telephones already working and in place. As many of the carriers required Central Office (“CO”) functionality, the TVA-P was upgraded to operate in a CO environment so that the devices can be placed at the CO or the users’ premises. With 48vDC a primary source of power at many CO locations a new version of the TVA-P is undergoing regulatory approvals to provide a complete carrier solution.

Obtain VoIP features without the expense or disruption of a “rip and replace” migration.

Enterprises migrate to IP telephony for a number of reasons. They want cost savings. They want to better serve their customers. They want to gain a competitive edge.

But most VoIP migration solutions are expensive, time consuming, and disruptive. They involve obtaining LAN assessments, purchasing new LAN switching gear, rewiring, and retraining. All to support new IP handsets that may not be necessary to obtain the benefits of VoIP. In fact, according to an August 2006 Gartner Research report, an estimated $20.6 billion will be wasted on IP screen phones over the next five years.

The Citel Portico™ Telephone VoIP Adapter (TVA™) changes the dynamics of VoIP migration by enabling enterprises to obtain all the benefits of IP telephony utilizing the PBX telephones and wiring infrastructure they already have in place.

Whether the enterprise is migrating to a Hosted IP platform through a service provider or managing their own on

md_porticopremise IP PBX, Portico simplifies the migration process, and is transparent to most users. With Portico, legacy PBX telephones become new IP endpoints, so replacement simply becomes unnecessary.

The economics of Portico are so compelling, enterprises can justify migration to IP telephony even in the middle of the traditional PBX “buy cycle”. Cost-savings, productivity enhancements, additional functionality, and converged applications are all within reach.

After a fast, simple Portico migration, enterprises on Hosted or premise-based VoIP achieve:
  • Reduced monthly telecom operating expenses through centralized voice mail, IP network utilization, and the elimination of PBX and/or Key systems across the enterprise.
  • Increased productivity through centralization, or even outsourcing, of voice network management combined with enterprise-wide distribution of features and applications.
  • Seamless migration to a unified communications platform.

With so much to gain, enterprises seeking the benefits of IP telephony and convergence have no reason to wait.

FAQ’s: Portico™ Telephone VoIP Adapter (TVA™)

What are the benefits of Portico TVA?

Portico TVA allows enterprises to obtain the enhanced features of VoIP without a LAN assessment or upgrades, expensive new IP phones, or business disruption. Enterprise migration to VoIP is more affordable, faster, and easier with Portico.

Does it matter how many locations or employees there are in the enterprise?

Not at all. One of the cost benefits of VoIP is its ability to seamlessly link distributed locations over a public or private IP network, utilizing only one telephony platform. One or more Portico TVA units are deployed at each location (instead of new IP phones and LAN cabling), and connect directly to the platform over an IP network.

The enterprise won’t need new phones and LAN upgrades to support the additional voice traffic?

No new phones or cabling are required. With Portico TVA, digital (PBX), P phone (Centrex), and analog handsets are enabled with IP features and functionality, and applications that require a larger screen are accessed through a browser window. Voice traffic travels over existing Cat3 cabling to the Portico TVA, where it is translated into a packet-based VoIP communication. Additional LAN bandwidth is not needed.

TVA instead of a “rip and replace” VoIP migration strategy?

Enterprises typically save on a per port basis for migration costs with Portico TVA. Savings depend on the extent of LAN upgrades needed to provide sufficient bandwidth for voice traffic, and the type of IP phones that would have been selected.

Can the enterprise keep its PBX and use Portico TVA to obtain the enhanced features and benefits of VoIP?

No. Only IP telephony platforms, whether delivered via a service provider or an on-premise IP PBX, can provide VoIP’s extensive features that improve productivity and simplify voice communications.

Can I use multiple handset types with a Portico TVA deployment?

Yes, but only one brand per Portico TVA unit. Each Portico TVA unit is configured to work with a specific brand of manufacturer’s phones. For example, one Portico TVA unit can connect multiple Nortel Norstar® handset models to the IP telephony platform, and a second unit can connect multiple Avaya Definity® handset models.

Which IP telephony platforms is Portico TVA compatible with?

Portico interoperates with leading platforms from Asterisk, Avaya, BroadSoft, Cisco, MetaSwitch, Pingtel, and Sylantro.

Who should consider Portico TVA?

Any enterprise that wants the benefits of VoIP without the typical expense and disruption should consider migrating to an IP telephony platform with Portico TVA.

What new equipment does the enterprise need to deploy VoIP using the Portico TVA solution?

With a premise-based solution, the enterprise will need to select and install an IP PBX, and deploy one Portico TVA for every 24 users (12-port configurations also available for smaller deployments). With a hosted service provider, the only new on-premise equipment needed is Portico TVA units.

What if the enterprise plans to deploy new IP phones for some staff anyway?

A partial deployment of new IP phones frequently doesn’t add enough traffic to the LAN to require an upgrade. However, it’s recommended that the enterprise assess its available bandwidth before adding voice traffic to the LAN.

Are there enhanced features provided by the IP solution that do not pass through Portico TVA to the end user?

Almost all VoIP features will pass through to the end user. Some are mapped to the phone, while features that require a larger screen, like Call Manager, are accessed through a browser window. Occasionally a specific feature from an IP PBX or hosted IP platform won’t pass through, but this is rare, and can usually be determined before deployment.

What kinds of handsets interoperate with Portico TVA?

Portico TVA interoperates with more than 75 handset types from major manufacturers.

How is Portico TVA installed?

Installing the Portico TVA is very straightforward. With a hosted service provider:
1. Select and sign up with a service provider
2. Connect Portico TVA to the WAN connection
3. Disconnect the handsets from the PBX, and connect them to Portico TVA
4. Configure the handsets via web interface and terminal connection
5. Disconnect the PBX

With an on-premise IP PBX:
1. Install and configure the IP PBX
2. Connect Portico TVA to the IP PBX over the enterprise LAN or the Internet
Steps 3, 4, and 5 are the same as with a hosted platform, above.
