1.1. ACD Interface Requirements
A Aura Contact Center ACD configuration consists of a Meridian 1 switch
(Option 11C, Option 51C), a NCCM server (formerly known as Aura
Contact Center Server or SCCS), a switch Administration & Data Server
(ADS). The Meridian 1 switch, the NCCM server, and switch ADS are
connected together via a private Ethernet subnet that Avaya refers to as an
ELAN. (See XFigure 1X.)
Figure 1: Aura Contact Center Hardware Configuration
The NCCM server is also attached to a public Ethernet subnet called a
CLAN. The NCCM (NCCM) Administration & Data Server and the nodes
on which the system software runs (PGs, CallRouter, etc.) are also
attached to the CLAN. All communication is based on TCP/IP.
The Aura Contact Center Peripheral Gateway (PG) can run in simplexed
or duplexed configurations. In a duplexed configuration, only one side of
the PG communicates with the ACD at any given time.
The Meridian 1 switch performs basic telephone switching functions.
Most of the intelligence of the system is in the NCCM server. The only
way Unified ICM can communicate with Aura Contact Center is via the
NCCM server.
The Aura Contact Center PIM does not support configurations that use
Nortel’s Meridian Link Services 4.0 on a NCCM server. Meridian Link
Services 4.0 is supported only for the Meridian PIM.
