What is Lync Server?
What is Lync Server?
• Lync not LINQ• The new name for OCS• An IP-PBX or traditional PBX replacement• A new breed of software-based telephony• Fully immersed within your PC or *Mac desktop
user experience – Office, SharePoint & Lync Client• The heart of Microsoft’s UC stack – complimented
by Exchange Server 2007/10 Unified Messaging*Unable to schedule conferences via Mac edition of Outlook

Office Communications Server
Microsoft®
A PBX companion – high level deliverables include:• Voice calls via existing handsets (RCC) and Communicator/“Optimised
Devices” (EV)• Video calls• IM and presence• Mobility (including IM, presence and single-number reach)• Collaboration (desktop/file sharing, group chat and *dial-in conferencing)
*Office Communications 2007 R2
Then…

A PBX replacement – via added functionality:• Enhanced resilience - without the need for h/w load balancing (web workloads still
require HLBs)• Survivable Branch Appliance – a purpose-built appliance for branch deployments• Call Admission Control (CAC) – for the prevention of VoIP over subscription• Enhanced 9-1-1 (NA only) – CU1 delivers location functionality• Superior conferencing - voice announcements, lobby and an integrated client! (no
Live Meeting client or Outlook Conferencing add-in)

Technical differentiators from OCS
• Planning Tool• Export to Topology Builder (.tbxml)
• Topology Builder• Tool used for .tbxml import, topology setup, modification and
validation prior to deploying first server and publishing within the Central Management Store (CMS)
• Communicator Web Access (CWA) depreciated in Lync – OCS 2007 R2 CWA can be deployed
• Call forking is also depreciated, RCC still available for 3rd party PBX integration
Setup, deployment and management changes worth mentioning
28/07/2011 Microsoft Unified Communications User Group London (MUCUGL) 8
• PowerShell and Silverlight-based Lync Control Panel replaces MMC
• Role-based access control (RBAC) for delegation of specific Lync tasks, incl. 11 out-of-the-box roles
• Mediation role can now be collocated with front end role = minus 1 server
Essentially one Standard Edition Server could support Enterprise Voice, IM, Presence and Conferencing for up to 5000 users!
Setup, deployment and management changes worth mentioning (continued..)
28/07/2011 Microsoft Unified Communications User Group London (MUCUGL) 9
• Replaces Active Directory for most configuration storage (phone numbers still held within AD)
• The CMS data is held within a SQL database
• Centralises the administration of all Lync Server roles (including Edge servers)
• There is a minimum requirement of 2 x CMS databases - 1 x master (RTC) and 1 x replica (RTCLOCAL)
• RTC and RTCLOCAL databases are replicated
• Resilient architecture – Front End Server CMS (replica) will continue to function where connectivity is lost to the master
Central Management Store (CMS)
28/07/2011 Microsoft Unified Communications User Group London (MUCUGL) 10
• Put simply CAC is the bandwidth management service built into Lync Server
• CAC bandwidth policies can be set to control
• Audio - max bandwidth (kbps) assigned for all/individual sessions• Video - max bandwidth (kbps) assigned for all/individual sessions
• Policies are applied between sites, where multiple network subnets can be associated
• Alternate routes can be utilised where over-subscription occurs, i.e. when local ISDN is at capacity then a route to PSTN over an Internet based SIP trunk could apply
Call Admission Control (CAC)
28/07/2011 Microsoft Unified Communications User Group London (MUCUGL) 11
• Media bypass reduces the load on your Mediation servers (allowing support for up to 5000 users, where Front End and Mediation roles are collocated)
• This is achieved by negating the need for transcoding between the Lync client or phone and the voice gateway
• In this scenario the G.711 voice codec is used, instead of RTAudio
• Recommended gateway vendors include AudioCodes, Dialogic, NET and Ferrari
Media Bypass
