OpenScape 4000 is a converged IP communication platform, ideal for medium and large converged (IP and TDM) enterprises, scaling from 300 to 12,000 users on a system.

 OpenScape 4000 is the No. 1 converged voice solution in Europe and India, and is highly-placed in Gartner’s 2013 Unified Communications Leaders ‘magic quadrant’.

 It supports the full range of OpenScape UC applications, so you can look forward with confidence to increased workforce productivity.

OpenScape 4000 enables you to offer the best of both worlds – VoIP and UC – to drive productivity, and protect your investments by integrating into existing network wiring, devices, features, and software.

And you can trust it: OpenScape 4000 is deployed in more than 25,000 customer installations across 80 countries with more than 25 million licenses in service.

OpenScape 4000 runs on standard server hardware, allowing for data center deployment, or as a traditional PBX chassis.

The future-proof architecture supports IP-distributed branch concepts and complex corporate networks as well as stand-alone systems.

FlexLicensing means your user licenses can move to a SIP-based OpenScape Voice solution. And you can take advantage of the security provided by OpenScape Session Border Controller, along with the savings of SIP trunking.

As a powerful and highly available communications solution, it offers a rich set of endpoints, mobility choices, edge solutions, unified communications and standards-based integration and interoperability with business-critical applications and

It supports this capability with a built-in assistant and powerful, easy-to-use set of system management apps.


IT architecture

Modular, stackable, reliable and seamlessly expandable, OpenScape 4000 V7 offers an ideal solution for an enterprise communications infrastructure – regardless of size and location requirements.

With its modularity, the availability of scalable access points, software- based branches, plus powerful networking support – analog, TDM, or IP – it provides a perfect solution for seamless expansion and can be integrated with any IP infrastructure.

The OpenScape 4000 communication server is the highly available central control unit with redundant power supplies and redundant LAN interfaces. The OpenScape 4000 V7 duplex architecture enables complete redundancy for call control, CSTA application connectivity and administration, even in geo-separated locations.

The AP 3700 access points and the new HiPath Access modules fit in a standard 19-inch shelf and are integrated directly in the IT infrastructure.

The OpenScape 4000 SoftGate application offers software-based and cost-effective OpenScape 4000 VoIP functionalities running on standard x86 server platforms.

The OpenScape 4000 communication server can be flexibly implemented in configurations to support smallest to the largest enterprise. It supports up to 15 directly-connected access points, plus 83 IP-distributed access points, HiPath Access or SoftGate branches.

A maximum of 12,000 subscribers can be supported in these configurations per OpenScape 4000 communication server. Configurations with up to 100,000 users can be implemented without difficulty in networked systems.

The modular structure of OpenScape 4000 also enables cost-effective resilience solutions to be realized in small and mid-sized configurations.

OpenScape 4000 Server Deployments

The new architecture of the converged IP system OpenScape 4000 allows a pure software installation at a standard server that is equipped with a Linux operating system.

With this software version, existing customer solutions can be migrated to a data center and IT-based solution in which traditional TDM and analog devices as well as CO trunks are still supported.

OpenScape 4000 V7 now offers two different deployment options:

  1. Compact PCI (cPCI) OpenScape 4000 communication server
  2. Industry standard servers with Linux

Both deployment options support up to 12,000 users per Linux server or duplex cPCI deployment. Up to 100,000 users can be managed by the OpenScape 4000 Manager system administration software.

Compact PCI Server

The compact PCI server option (cPCI) supports converged IP requirements involving applications with a big number of analog and TDM devices, DECT applications, or specialised industry-sector applications.

The new cPCI hardware offers new redundancy opportunities and can be deployed in a highly scalable and secure way in data centers.

Linux Servers

Deploying the OpenScape 4000 on industry-standard Linux servers is suited for converged-IP telephony requirements and is well suited for highly-distributed deployments.

It provides a low total cost of ownership for both hardware and maintenance and, like the cPCI option, is scalable and secure.

OpenScape 4000 SoftGate application

The OpenScape 4000 SoftGate application provides cost-effective VoIP functionalities with reliable branch survivability options and an easy IT integration in the OpenScape 4000 solution and management suite.

This new software application offers full HiPath feature access for IP endpoints and SIP connectivity for trunking and subscriber, based upon a standard server with Linux SLES 11 SP1.

Any OpenScape 4000 SoftGate site integrates seamlessly in the communication system and network like any IPDA access point (AP 3700 IP with HG 3500) – in terms of features and administration.

The open architecture of the OpenScape 4000 SoftGate application enables integration in a VMware virtualisation environment. In addition, the OpenScape 4000 SoftGate application supports IPV7 SIP trunking and enables Peer-to-Peer video integrations with HD video systems or softclients. Using SoftGate media server capabilities, it can also be used for software-based music-on-hold and announcements deployments.

With this application, customers can reduce capital cost (CAPEX) plus operational cost (OPEX) and deploy centralised applications with uniform user experience.

HiPath Access

HiPath Access is a cost effective and 19-inch modular solution that can be deployed in survivable branch solutions and into your IT infrastructure.

It consists of flexible, stackable and highly-scalable 1U modules which provide all required analog, digital and DECT interfaces of a branch solution with HiPath Access 500 and OpenScape 4000 SoftGate.

Access Point Emergency concept for branches

OpenScape 4000 AP-Emergency completes the survivability functionality for access points (AP), HiPath Access 500, and OpenScape 4000 SoftGate branches.

With APE, a continued operation is also possible in the event of a failure of the central call control or WAN Link failure to central call control. In cases of host system failure, the survivability function can assume control of one or several different access points (AP 3700, HiPath Access 500, and/or OpenScape 4000 SoftGate); thus ensures sustained communication capabilities within the enterprise. A prerequisite is that the APs controlled by a survivability unit still have a functional IP infrastructure.

This gives you optimal security for all access points and IP branches connected to the OpenScape 4000 communication server.

Signaling and Payload Survivability for IP branches

This function performs that voice is routed via PSTN and signaling is routed via IP or PSTN survivability connections for IP branches. This expanded survivability functionality can be used as an alternative dynamic path if the IP network fails, all available VoIP resources are occupied, or IP quality is found to be poor. Also, static configuration of payload routing over PSTN can be used for smooth transformations of existing branch offices from PSTN to IP networking.

This flexible mix between IP and TDM networking for payload and best possible signaling capabilities allows the migration to homogeneous branch networks and the implementation of centralised applications as required. Signaling and Payload survivablity allows highest flexibility in optimisation operational expenses (OPEX) – in any market or communication environment.
