1 Topology overview - deployment design
The Alcatel-Lucent OmniPCX Enterprise Communication Server is part of the next generation of
enterprise IP-PBX communication systems. It is designed around native IP technologies and allows
the customer to deploy mixed or legacy solutions to support a converged data-voice network.
The Alcatel-Lucent OmniPCX Enterprise Communication Server architecture provides a single logical
communication system whose benefits are:
– Scalability and ability to increase system performance and increase the number of
supported users: flexible solutions for businesses of all sizes
– Resiliency and reliability, producing a highly stable service level consistent with its use
– Easy access from anywhere: communication solutions fit to all types of user profiles
– Technologically transparent: smooth migration of existing network
– Easily upgradeable and future-proof: protect and leverage existing investments
This flexible architecture allows the Alcatel-Lucent OmniPCX Enterprise Communication Server to be
installed and operated in a totally distributed design configuration on a single site (campus) or across
multiple sites.
The Alcatel-Lucent OmniPCX Enterprise Communication Server is designed to meet the needs of all
types of architectures and configurations. The choice of a telecommunication solution is mainly based
on topology and architecture. Alcatel-Lucent OmniPCX Enterprise Communication Server solutions can
address the following deployment models, offering state-of-the-art telephony services:
– A single-system for a local environment. The simplest package is based on a single
Appliance configuration containing embedded applications.
Depending on the licenses, users can access the Messaging, Conferencing, Collaboration,
Security services.
– A centralized call handling system with distributed hardware solution for a campus
environment or multi-site environments (e.g. branch offices). A centralized call handling
implies a central Alcatel-Lucent OmniPCX Enterprise Communication Server, controlling
one or more remote Media Gateways, located locally or in remote sites
– A distributed call handling system with distributed hardware solution for multi-site
environments. A distributed call handling implies several Alcatel-Lucent OmniPCX
Enterprise Communication Servers. The Alcatel-Lucent OmniPCX Enterprise
Communication Server can be networked to cover multiple buildings, sites, or campuses,
at various geographic locations. In these types of configurations, each Alcatel-Lucent
OmniPCX Enterprise Communication Server is considered as a network node
Alcatel-Lucent OmniPCX Enterprise Communication Server solutions are not limited by the network
infrastructure and can operate on IP (H.323 and SIP included) and TDM.
These different types of infrastructure can co-exist in the enterprise.
The OmniPCX Enterprise allows a network consisting of several sites to be built with a high level of
service integration and transparency. It also allows interconnection with legacy PCXs or with next
generation IP-PBXs using digital TDM or IP technology.
