Alcatel-Lucent Enterprise Communication Solutions
April 2014 Offer
– IP Touch Security service (encryption)
– T.38 fax communications over IP
– Possibility to configure heterogeneous numbering plan in the ABC supranetwork
– Compatibility with current network services of the Alcatel-Lucent OmniPCX Enterprise
Communication Server (e.g. Automatic Route Selection)
An ABC-F Trunk Group on IP can only be configured between two nodes (of different ABC sub-
networks) in R9.0 or higher. An ABC sub-network can contain nodes in releases lower than R9.0 (this
depends on the Alcatel-Lucent compatibility between releases).
Use of ABC trunk groups on IP implies the following restrictions:
– Both ABC trunk groups on IP and TDM leased lines cannot be supported at the same time
between two ABC sub-networks
– Only one ABC trunk group is supported between two nodes located on different ABC sub-
networks
3.2 ABC network features
Distributed call handling is available for enterprises with multiple sites.
Each site is equipped with a specific Communication Server E-CS (which may be duplicated), using
the same basic software as typical single-site configurations (classic or IP configured).
The servers are interconnected to provide the customer with all the expected benefits of networking
(cost optimization, centralized resources, transparent service for the end user, centralized
management, etc.)
These services are supported by the enhanced ABC (Alcatel-Lucent Business Communications)
protocol, which is compatible with the QSIG-GF standard.
The ABC protocol has four main modules:
– ABC-F for feature transparency - provides users with the same telephone services
regardless of their location in the enterprise.
– ABC-M for network wide management - allows centralized, simplified management
– ABC-R for network wide routing - optimizes routing for cost/resource optimization and
simplifies routing management
– Virtual services which carry the ABC-A (Application) protocol which allows the
centralization of applications (e.g. voice mail centralization) but also specific information
relating to the call distribution or multi-line feature (there can be managers located in one
node and their assistant located on another node, a phone connected on a node may be
supervised from a phone connected on another one, etc.)
