IP PBXs Unwrapped

As businesses seek to migrate to IP-based telephony solutions, introductions of pure IP and converged systems are on the rise, according to the latest research. Database publisher and analyst group TelecomTactics finds that pure IP systems and converged systems represent a combined 70 percent of new system introductions in 2004 compared to only 35 percent in 2000. Traditional telephone systems that can be IP-enabled or those with no support for VoIP are on the decline.

Businesses are moving to take advantage of IP-based solutions, but protection of their current equipment investment remains a priority. The goal is to avoid high costs by retaining and reusing existing line and station cards and telephones on a new IP system. Converged systems that support both packet and circuit switching are a good fit since these systems accommodate connection to analog and digital telephones, as well as newer IP devices. In 2002, the enterprise telephony market experienced a surge in introductions of converged systems by Avaya, Mitel Networks, NEC, Siemens and other manufacturers.

Pure IP platforms utilize IP peer-to-peer switching, connecting stations directly to each other through the IP network, but can incorporate optional gateways or interfaces for traditional analog and digital connections.

IP networking benefits businesses with distributed locations and makes it more cost-effective to include small branch offices in a network. In 2004, a number of manufacturers introduced pure IP platforms, including 3Com, Comdial and Toshiba with small and mid-sized offerings, and Cisco, NEC and Nortel Networks with platforms for larger enterprises (see system profiles).

Businesses benefit from new IP-based employee productivity applications, including instant messaging, presence, IP audio and video conferencing and collaboration. Collaborative applications help to reduce travel and facilitate communication among dispersed workgroups, allowing employees to easily share information from any location on a corporate network. Web-based conferencing lets conferees record presentations and use white-boarding or engage in face-to- face video calls. Presence-based communication improves employee and customer interactions, allowing users to define how they wish to be reached (via desk phone, cell phone, e-mail, instant messaging or other media). New sophisticated, IP-based contact center functionality adds agent/supervisor instant messaging, collaborative Web browsing, e-mail automated response, live Web chat and multimedia queuing/routing to name a few.

Further studies show that support for IP telephones on business telephony platforms continues to rise from only 20 percent in 1999 to more than 80 percent in 2004. Leading manufacturers are rounding out their IP phone portfolios, offering a range of choices from cost-effective, entry-level and mid-range phones to advanced models. By transmitting voice over a companys data network, IP telephones can reduce costs and easily extend office telephone features to a remote location such as a home or branch office. Corporate directory access, call-history logging, conversation record, large pixel-based displays, color touch-screens and even interoperability with a PDA are among the many popular IP telephone features.

3Com NBX V3000

3Com Corp’s NBX V3000

3Com Corp’s new NBX V3000 is an IP PBX platform for small offices or small and medium businesses. The modular NBX V3000 targets businesses with two to 40 users, but can expand to support as many as 1,500 stations using the SuperStack 3 NBX expansion chassis. The NBX V3000 unit includes four CO line ports; one analog station port; 15 ‘Group 2’ phone licenses for 3Com 3102 IP phones; a four-port auto attendant; voice mail capability with 400 storage hours; and the NBX NetSet utility for browser-based administration. This pure IP solution for small businesses delivers IP features and functionality at a key system price, according to 3Com.

Like 3Com’s earlier NBX platforms, the NBX V3000 voice-over- LAN solution includes auto attendant, voice mail, call detail recording, TAPI software and browser-based Web administration - a cost savings over typical PBX systems that require external equipment. The initial NBX V3000 system has 128MB memory, supporting up to 250 devices, eight Virtual Tie Lines and 12 auto attendant/voice mail ports. A 512MB memory upgrade (for a system total of 640MB) increases capacity to 1,500 devices, 48 Virtual Tie Lines and 72 auto attendant/voice mail ports. The SuperStack 3 NBX expansion chassis and interface cards enable the system to handle T1/PRI trunking and additional CO lines up to a 720-trunk capacity. The expanded NBX V3000 has the same capacities as the SuperStack 3 NBX, but does not support optional redundant disk mirroring or redundant power.

The 3Com NBX V3000 is compatible with all 3Com interface boards, gateways, 3Com phones and NBX software applications, providing investment protection for NBX customers.

Alcatel’s OmniPCX Office
