NEC-VG3-BranchHub |
NEC VG3 BranchHub™ Media Gateway connects the Sphericall IP PBX to local telephone circuits. It supports twelve phones and six local analog phone lines. The VG3 BranchHub communicates with the rest of the Sphericall system through the WAN or MAN. The BranchHub can be configured for G.711 and G.729 AB voice encoding to optimize both system and network performance. Designed for the small branch office, the VG3 BranchHub connects to the public switched telephone network (PSTN) where digital service is unavailable or cost-prohibitive. Remote management keeps on-site service calls to a minimum. Power failure transfer (PFT) keeps phones connected to the PSTN if there’s a network or power disruption. The BranchHub enhances safety by routing 911 calls to the nearest local response center. Expand the capacity of the BranchHub office by adding more Sphericall media gateways. There are economic efficiencies to the BranchHub as well. BranchHub hardware and software does the job of separate station-side and trunk-side media gateways at a fraction of the cost. Of course, no proprietary PBX hardware is necessary–the phones operate as part of the distributed Sphericall system. Intra- and inter-LATA toll charges are minimized with multiple entry points into the PSTN. Small Office, Big Features When your site needs a few phones, local line access and access to the Sphericall system, the BranchHub is the perfect choice. Your BranchHub-attached phones function the same as any other phone on the Sphericall system. You can use Sphericall Desktop software for point-and-click access to call controls, phone setup and more. Fail-Safe Reliability The VG3 BranchHub keeps you connected to the phone network in the event of a network or power failure. Up to six of the twelve phones attached to the BranchHub automatically switch to the PSTN, so both inbound and outbound calls get through. Add a Sphericall Manager Server to the branch site for even higher availability. Easy Installation and Maintenance BranchHub technology is compatible with all other components in the Sphericall system. It auto-discovers the Sphere Manager for automatic configuration instructions and firmware updates. The BranchHub is managed from a central administrative console for convenience and consistency.

NEC-VG3-COHub |
NEC VG3 COHub™ Digital Trunk Media Gateway links your broadband data network to the public switched telephone network (PSTN) or a legacy PBX. It supports ISDN and Q.SIG over T1 or E1, so it fits a broad spectrum of solutions. It also links PBXs using your broadband network and Sphericall Manager™ technology, instead of requiring costly tandem switches and leased lines. The COHub gateway is easy to implement and manage. It auto-discovers its Sphericall Manager unit to receive configuration, firmware upgrades and other instructions from the Manager. A built-in monitor jack makes line testing easy. Maintenance and monitoring is done from a central administration console or a secure, remote PC connection. The COHub can be configured for G.711 and G.729 AB voice encoding to optimize both system and network performance. The COHub design supports the telephony features you expect, such as direct-inward dialing (DID), caller ID and enhanced 911. The COHub gateway is part of the Sphericall total communications system, which brings network telephony to thousands of users today. Designed for Flexibility and Growth The COHub gateway attaches to your Ethernet or ATM broadband network using copper or fiber-optic cabling. It attaches to the phone company using T1 or E1 circuits, either directly into the PSTN or through your existing PBX. In a distributed network, multiple COHub units give you local PSTN access in multiple locations. The modular design makes it easy to add capacity when—and where—you need it. Enhances Legacy PBX A VG3 COHub lets you expand your PBX’s capabilities without an expensive PBX upgrade. It integrates seamlessly with many legacy PBXs from Nortel, Lucent, Fujitsu and others, expanding the number of users and offering enhanced features without disrupting your current users’ service. COHub units also connect separate PBXs over your broadband network. Quality-Reliability-Availability The COHub supports industry standards —and your high expectations—for superior voice quality. It supports multiple Quality of Service (QoS) standards including 802.1 p/q, CBR and DiffServ. Dynamic load balancing optimizes resource use and helps ensure service availability so that calls always go through. Bandwidth-on-demand conserves network resources. The COHub even has built-in surge and lightning protection. Telephony Interface

NEC-VG3-MeetingHub |
VG3 MeetingHub™60-port Conferencing Bridge provides on-demandconferencing for your enterprise and eliminates 3rd-party conference call service fees.
The VG3 MeetingHub uses the “meet me” model for conferencing. Participants simply dial a conference bridge extension from inside or outside the Sphericall system. Using the Sphericall Desktop, users can see a listing of all conference participants. Callers can dial directly into the conference bridge or can be transferred in via “drag & drop” call management from the Sphericall Desktop. The VG3 MeetingHub is an easy-to-deploy network appliance that enables you to avoid the costs of 3rd party conference services while increasing productivity and ease of use for your employees. |
NECVG3-PhoneHub |
NEC VG3 PhoneHub™ Media Gateway connects analog phones, modems and fax machines to your data network. You don’t need special phones or wiring. Standard analog phones connect over regular wiring to the PhoneHub ports. The PhoneHub can be configured for G.711 and G.729 AB voice encoding to optimize both system and network performance. The VG3 PhoneHub device delivers the dial tone, busy signal and other information tones to the network phones. It also delivers line power up to 2000 feet away to analog phones, over regular cat 3 (or higher) wiring. Because phone system availability is a number one requirement, the PhoneHub automatically switches one phone to the public phone network in the event of a power failure. A PhoneHub unit is one of the primary building blocks of the Sphericall system. Expand capacity 12 or 24 ports at a time by adding more PhoneHubs—up to 30,000 total ports. The PhoneHub, BranchHub™, COHub™ and Sphericall Manager components work together seamlessly. Your phone system can grow without changing technology. Feature Rich The PhoneHub supports different media connections to Ethernet and ATM networks and works with a variety of phone sets. It supports the standards for caller ID, message waiting and other advanced features. It’s also compatible with modems, fax devices, music-on-hold, paging and encryption technology. Easy to Support Add a PhoneHub to your Sphericall system and it auto-locates its Manager and receives its instructions. PhoneHub configuration and firmware upgrades are done from a central administration workstation. Regular jobs such as moves, adds and changes become logical rather than physical tasks—thanks to the ability to remotely manage PhoneHubs. Engineered for Reliability and Availability PhoneHubs keep phone service going under critical conditions. A total power failure activates the PhoneHub fail-safe switch to the public phone network so calls can still be made from a selected phone. If a PhoneHub loses connection to a Manager unit (because of a power failure or network failure) it automatically links to an alternate Manager. Your calls keep going through. Telephony Interface
