3Com NBX V3000 IP Telephony Solution


The 3Com® NBX® V3000 Analog platform is a full-featured IP telephony solution designed for small- and medium-sized organizations moving to a Voice over Internet Protocol (VoIP) architecture. Its ease of use allowsnon-technical personnel to make individual or system-wide changes withthe click of a mouse. The system’s ability to scale up to 1,500 devices andto support standards-based protocols, including Session Initiation Protocol (SIP), gives organizations the confidence to choose the NBX solution for their current and future telecom needs. With a built-in analog gateway interface, the platform can connect up to four analog loop-start central office (CO) lines directly to the Public Switched Telephone Network (PSTN), reducing configuration time and its related expense. Additionally, the NBX V3000 Analog solution—in combination with an NBX Expansion Chassis—accommodates further communications options via T1/E1, PRI, analog and BRI trunking. To increase productivity and reduce operating costs, the solution also features a host of integrated applications, including voice messaging that provides a voice mailbox with auto-setup for every user, call center software that enhances the efficiency of agents in a queue, as well as easy to set-up hunt groups, auto-attendant, supervisory monitoring and call reporting. Email integration, supported on any IMAP4-compliant email system, offers the ability to share a common inbox for email and voice messages. Plus, V3000 Analog solutions let organizations centrally manage IP telephony services via the web with the 3Com NBX NetSet™ management application.


Protect Investment with Multiple Protocol Support
NBX V3000 Analog platforms with R6.0 and higher system software can operate in either of two modes: Standard NBX or SIP mode. Standard NBX mode utilizes the traditional protocol on which six generations of 3Com NBX applications have been built since 1998, while SIP mode allows the platform to communicate with third-party SIP-compliant devices and applications. 3Com’s goal of ensuring its customers access to continuously evolving telecom standards, maximizes functionality and the return on investment (ROI) from NBX solutions.

Enable Business Applications with SIP
SIP support unlocks access to advanced software that optimizes the productivity-
enhancing benefits of VoIP technology and facilitates employee
communications with collaborative tools such as IP Messaging and IP
Conferencing applications.

Increase Productivity with Built-In NBX Automatic Call Distribution (ACD)
Call center hotline, help desk and telesales staff work more efficiently with NBX ACD software included in the V3000 Analog platform. Two agent licenses are packaged with each platform and additional licenses are available with key-code activation. Supervisors obtain real-time, up-to-the-minute vital statistics on call center performance via voice monitoring or on their computer screens with PC-based software.

Ease IP Telephony Implementation
Standards-based design, including support for switched IEEE 802.3af Power over Ethernet (PoE), facilitates seamless integration with existing network infrastructure. The web-based NBX NetSet management utility, hosted by the NBX platform, provides intuitive system configuration that lets organizations avoid the need to train personnel in using commandline interfaces or new programming languages.

Match IP Phone Choices To Any Application and Budget
3Com helps organizations leverage existing infrastructure investments by offering a range of IP phone choices, all with robust feature-sets. Options include 10/100/1000 Mbps Ethernet/IP phones, softphones, receptionist consoles and cordless phones that run in either standard NBX or SIP call control mode. Where secure connectivity needs to be maintained while roaming through a business location, 3Com also offers the SIP-based 3108 Wireless Phone, an 802.11b/g-compliant wireless handset in a flip-phone form factor.

Cost-Effectively Expand To Meet Evolving Needs
Organizations can boost capacity or add functionality with practical keycoded software upgrades that let them align their needs and budget. With cost-saving incremental licensing, they can scale their NBX system up to 1,500 devices (lines/stations with maximum of 720 PSTN lines).

Create a Seamless Multiple Voice Network
NBX V3000 Analog solutions connect not only branch sites to corporate offices, but also remote and home office workers to their main office convergence services.
