INTRODUCTION
The SV8500 is a premier IP Communications server from NEC’sUNIVERGE®360 series of models.It supports voice, unifiedcommunications and mobility solutions for tens of thousands of users. Designed to easily andefficiently scale, it meets the needs of the largest enterprises, supporting up to 192,000 ports in a networked environment. It is implemented as a 3RU server, but may also include up to 16 8RU PIR’s. The server is loaded with the main, feature pack, and any system software options. It is the Telephony Processor for the system handling all activities associated with IP Peer-to-Peer communications as well as the traditional TDM telephones. It controls all of the “Protocol Handling” functions of the IP terminals and trunks as well as manages the communications between SIP devices/terminals and IP Peer-to-Peer or TDM devices.
The server functions on a Linux Operating System Platform (O/S) wherein IP based Telephony interconnection is possible through a true client/server IP PBX design.Utilizing the Linux platform leverages from the flexibility of operating in a redundancy option configuration, to provide a reliable connection for IP terminals, gateways and PC soft-phones. NEC maintains an exceptionally high MTBF (Mean Time Between Failures) with this platform by incorporating flash memory cards as opposed to hard disks as used in traditional servers.
The solution consists of the following items:
- The SV8500 as a 19” Rack mountable 3RU server. This hardware platform utilizes an industry standard Intel processor and is powered directly from AC100-240-volts or DC-48-volts. This server controls the features and licensing options for the system in addition to the Processor for managing communications between SIPdevices, TDM devices and extended SIP terminals as IP Peer-to-Peer.
- A 19” rack mounted expansionchassis is available if needed.
- In addition to the servers, a range of distributed IP media converters and gateways is also available to cater for access to the traditional services at the host site or at remote locations.
At the heart of the system is an IP-PBX based on a true client/server design platform that does not require circuit switched common equipment hardware for support of any analogue stations or trunk circuit requirements.A generic full software feature package comparable to those previously available only with traditional circuit switched PBX systems are provided to customers. Key features that typically all customer look for such as; survivability, redundancy,reliability, an extensive range of telephony features, and terminal options are provided.
SCALABILITY
The server has primarily been designed for customers who require a significant percentage of their telephony equipment to be IP based for desktop and/or wireless. It is very easy to scale due to the simplicity of its build rules and licenses and offers a per port growth path for its IP connectivity, with a maximum capacity in a standalone configuration of 6,144 ports. However, with the addition of the optional NEC Fusion software (FCCS) a solution can be expanded for up to 192,000 ports in a feature transparent cluster. A high density gateway chassis TDM (PIR) can be deployed if required which supports up to a maximum of 384 ports.
SURVIVABILITY
Multiple levels of solution survivability are offered by the server.An alternative registration server called a SR-MGC is implemented as the lower level of survivability. One or more SR-MGC servers can be deployed remotely from the host on a WAN.
Their implementation location would be dependent on redundancy levels required and the overall network design. IP Terminals and IP Gateways support multiple registration options and they can take advantage of one or many SR-MGC’s should the network to the host be lost.
Hot standby host servers are at the very top level. In case the primary server fails, a hot standby system providesfull service tothe desktop IP terminals, IP devices, TDM high densityGateways, and others by mirroring the host.
LEVERAGING
NEC has a strong focus on supporting customers who have previously purchased their products and consequently offer various options for backward compatibility.
- Regular software releases available which allows customers to gain access to all of the latest software version features by implementing a software upgrade.
- Most packages from the large IMX, ICS and IPX NEAX models of PBX are still compatible with the newer high density TDM chassis (PIR).
- Supports CCIS links to any other existing NEAX PBX systems that support CCIS Trunking.
SUPPORTED OPTIONS
A wide and varied range of integrated communications software options, features, terminals and devices are supported. This provides customers with the capability to build extremely flexible and robust configurations and with the strength to scale it to suit their immediate and future business needs.
SYSTEM SOFTWARE UPGRADES
Major software versions are being released periodically. These software versions only required for users looking at utilizing the additional and more recently incorporated features. Customers can skip several software releases but are still able to upgrade to the very latest software level if they have the appropriate hardware platform.
The system software can be loaded from a CD onto the system flash card. The new software version is then updated with a system reset which can be conducted at a time most convenient for the customer. A CPU reset for a typical system would normally take between 10 and 40 seconds before the system is back online. The reset time is still less than 2 minutes even for a very large system implementation.
INTEGRAL HANDSET SUPPORT
Connection of UNIVERGE desktop IP terminals that use Extended SIP signaling are allowed. From a user perspective, the desktop IP terminal will operate similarly to that of a traditional desktop digital terminal. This can dramatically reduce implementation costs due to the limited requirement for staff training.Hot-desking and individual operator security can be implemented simply by using thedesktop IP extension log-on, log-off capability. Significant network infrastructure savings can also be achieved by utilizing the additional PC switch port connection available on the advanced UNIVERGE desktop IP extensions.
In supporting mobile workforces, Voice over WLAN handsets utilizing Session Initiation Protocols are supported. The desktop IP extension can be configured with up to four alternate server addresses in order to cover WAN failure or loss of internet connectivity.
