The Communication, Collaboration, Content and Social (3CS) Reference Architecture provides frameworks for understanding — and guidelines for implementing — 3CS technologies. This Unified Communications (UC) Core Capabilities template describes the key services and features necessary to create a consistent, functional UC environment capable of supporting a wide range of needs. Using this template, enterprise engineers and architects can ensure that their UC system fits within the broader IT architectures that the organization adopts, adapts to meet future needs, and provides a platform for integration with other systems as well as addressing specific communications and collaboration requirements.
