Unified Communications Stretching The Infrastructure Mike Daly Group Head Unified Communications HSBC

Introduction Today IP, Ethernet, Cat5e & the odd bit of fibre ( “the plain old LAN / WAN”) has acquired the status of the information highway,is expected to last forever and support all communications past, current and future. The Infrastructure (whether Wired, Wireless or Broadband) is now the commodity carrier of Data, Voice and Video solutions to meet the increasing demands of changing working practises, delivery of multiple applications & services (or Unified Communications as the demand for User Presence and Mobility increases by the day . Applications & services are now more than ever dependent upon the delivery infrastructure as more demands are placed on it. The rise in Non Elastic / Contention Intollerant based services require the infrastructure to be capable of many additional features ranging from Access Security, Quality of Service, Application Prioritisation, Contention Management, Capacity Management and above all the ability to manage costs (tariffs, port allocation, IPT/ Video bandwidth & Backbone capacity. The paper aims to ensure integration & harmonisation between Equipment suppliers and Infrastructure Standards Groups (TIA-B, FIA, ECA) to ensure the User or Design Authority fully contribute and leverage infrastructure standards to meet the challenges of system and application delivery. The paperwill examine key design and management requirements for Communications using Broadband, Wireless & LAN / WAN Infrastructures and associated standards. Finally the development of “adequate” implementation specifications is key to position the infrastructure to meet current and future demands

Industry Requirements To ensure that the CMA and its membership are fully represented In the development and implementation of Infrastructure standards To actively engage with key industry groups TIA-B, FIA, & ECS to allow CMA contributions to standards and work items within the unberella TIA-B group that will directly impact CMA members in the design, implementation and support of communication systems To directly influence the development of standards To provide Users with an independent and agnostic source of advise and guidance at key design and network / infrastructure stages.

User & Design Guiding Principles Understand what you are asking for. Understand the complete network requirements and define them clearly. Don’t ask for the impossible. Understand the limitations of each delivery infrastructure vs service requirements ( LAN, 3G, Broadband, WiFI) Understand the impact of changing your requirements (time, cost, performance) Confirm backwards & forwards compatibility before you complain that it doesn’t work. Understand what you will get for your money. Understand how you expect to validate, accept, support, change, expand the network at the time of negotiation & ordering. Infrastructure Design Team Delivery & Actions , not Words No Voyages of Discovery. No Surprises. Honesty Agreed design requirements and system specification. Trust : Design & Supply ability. Trust in resolving technical & compatibility issues
