EXTender™ & PBXgateway™

Distributed enterprises utilizing a central PBX with advanced features and applications require IP migration solutions that leverage existing infrastructure investments, but also pave a road to the future of IP telephony.

A Step Toward VoIP Migration for Distributed Enterprises

Distributed enterprises utilizing a central PBX with advanced features and applications require IP migration solutions that leverage existing infrastructure investments, but also pave a road to the future of IP telephony.

Citel MCK’s EXTender™ and PBXgateway™ product suite accomplishes both objectives. Branch offices, call centers, mobile workers, and home-based workers connect to the corporate voice network over an IP network, while the enterprise extends the useful life of the existing PBX.

As a result, enterprises achieve:

  • Lower monthly telecom operating expenses through unified dialing plans and IP network utilization.
  • Increased productivity through centralization of PBX management combined with distribution of PBX features and applications across the enterprise.
  • Reduced requirements for individual PBX or Key Telephone Systems (KTS) at branch offices and call centers.

Citel’s EXTender and PBXgateway telephony solutions are designed for operational simplicity. Configuration, management, administrative, and diagnostic functions may be accessed using a dial up modem, local terminal, HTML, or Telnet connection.

For enterprises requiring the best of both worlds, Citel is the answer.

With a broad product suite configurable for enterprises with anything from a single teleworker to a large network of branch offices and mobile employees, Citel has the right managed IP telephony migration solution for you.

FAQ’s: EXTender™/PBXgateway™

Who should consider deploying an EXTender/PBXgateway solution?

Any enterprise with workers at multiple locations and significant investments in PBX infrastructure and equipment can benefit from an EXTender/PBXgateway deployment.

How are the EXTender/PBXgateway installed and configured?

The EXTender is connected to the phone(s) and the appropriate connection at the remote location.

The PBXgateway is installed within 500 feet of the central PBX. A network access device or router may be part of the configuration as well; click here for product spec sheets including sample configuration graphics, or talk to a Citel representative to find out exactly which equipment will be needed. Configuration is completed via intuitive web interface and/or terminal connection, depending on EXTender model.

What equipment will the enterprise need in addition to the Citel units to deploy an EXTender/PBXgateway solution?

All deployments require compatible handsets at each remote location. The EXTender 4000, 4100, 6000, IP6000, and 7000 also require a network access device at both the remote and central location.

How does the enterprise determine which EXTender/PBXgateway solution(s) is best for its needs?

There are several types of EXTenders, each for a different enterprise configuration. In summary:

  • EXTender 1000 is for teleworkers with analog lines
  • EXTender 3000 is for teleworkers with ISDN lines
  • EXTender 4000 is for teleworkers with broadband Internet connections
  • EXTender 4100 is for teleworkers and small office/home office (SOHO) users with broadband Internet connections
  • EXTender 6000 is for branch offices and call centers of up to 12 people, and can scale with the growth of the remote location
  • EXTender IP6000 is for branch offices and call centers that plan to migrate to a VoIP telephony platform within two years
  • EXTender 7000 is for branch offices and call centers of more than 12 people, and can scale with the growth of the remote location

EXTenders are terminated by compatible PBXgateways; in the case of EXTender 1000, 3000, 4000, and 4100 units, small deployments can also be terminated by series-specific switch modules.
PBXgateway I is compatible with EXTender 4000, 4100, 6000, and IP6000.
PBXgateway II is compatible with all EXTenders.

Does the enterprise have to use the same type of handsets at each location?

No, but all phones must be the same brand as the PBX. For example, if the PBX is a Nortel Norstar®, then all handsets must be Norstar as well, but can be a mix of model numbers.

What is EXTender? What is PBXgateway?

EXTender is the name for a suite of Citel products that extend the features and functionality of a central PBX or Key system to branch offices, call centers, teleworkers, and mobile phones. PBXgateway is the termination device installed at the PBX location in conjunction with an EXTender deployment.

What are the benefits of the EXTender/PBXgateway product suite?

They allow distributed enterprises to eliminate PBX and Key systems at remote locations. All employees utilize the same fully featured central PBX, saving money on equipment, maintenance, coordination, inter-office calls, a unified dialing plan, and more. EXTender and PBXgateway solutions also scale easily to the growth of the location. As new stations are added, another port on the EXTender and PBXgateway are utilized; when port capacity is reached, additional units can easily be added.

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

Scalability is limited only by the station capacity of the central PBX and available bandwidth.

How much money can the enterprise save by deploying an EXTender/PBXgateway solution?

For an existing branch office or call center considering a new PBX, solid savings can be expected. Instead of installing the new PBX or Key system, the location is outfitted with one or more EXTenders, and depending on network connection, an access device. Even if the remote location’s existing system is still usable, centralizing voice network administration frees up IT resources and reduces telecommunication expenses by up to 30%.

With single user deployments, savings vary widely, depending on whether the user also maintains an office workstation and how many outbound calls the user makes. Centralized voice network administration adds considerably to the savings realized with a single user deployment as well.

Which PBXs are the EXTender/PBXgateway product suites compatible with?

EXTender and PBXgateway solutions are compatible with leading PBX protocols, including Alcatel, Avaya, Ericsson, Iwatsu, NEC, Nortel, Panasonic, and Toshiba. Interoperability varies by EXTender; click here for product spec sheets, or talk to a Citel representative.

Which handsets are the EXTender/PBXgateway product suite compatible with?

EXTender and PBXgateway are compatible with more than 125 handset types.
