16 MC 3100 and CS 1000 deployment overviewCS 1000 data access considerationsThe MCG 3100 requires data access to the TLAN of the CS 1000. TheMCG 3100 uses the CS 1000 SPS as the SIP Signaling Proxy. The mediafor all calls to and from MCC 3100 clients is anchored on the MCG 3100.The MCG 3100 will accept or transmit RTP to any IP endpoint within theenterprise (e.g. Media Cards, Other SIP clients, IP sets).ExampleIf an UNISTIM set calls a user answering through the MCC 3100 on themobile phone the RTP for the active call will be between the MCG 3100and IP set directly and then forwarded from the MCG 3100 to the CS 1000media gateway (for the trunk call to the mobile phone)Careful consideration is required based on the data network and securityrequirements of the Enterprise to allow the public internet traffic toreach the MCG 3100 from the clients while at the same time giving theMCG 3100 access to the TLAN of the CS 1000 for SIP and RTP.Licensing requirementsCommunication Server licensing requirements• Requires CS 1000 Release 5.5• Uses SIP Access Port Licenses for CS 1000 SIP infrastructure support• Requires 1 Universal Extension (UEXT) for each MCC 3100 user. TheUEXT is configured with the Fixed Mobile Convergence Line (FMCL)subtype.MCC 3100 licensing requirements• Each MCC 3100 client requires a license.• Each license key can only be used once per user.• The MCC 3100 licenses are installed on the MCG 3100.The MCG 3100 allocates the license on a first come, first served basis asthe MCC 3100 registers with the MCG 3100.• There is no requirement to distribute licenses to each end user.• The MCG 3100 administrator can revoke licenses on a per user basis,if necessary, to reclaim user licenses.Nortel Mobile Communication 3100Mobile Communication 3100 and Communication Server 1000 Solution Integration GuideNN49000-315 02.01 2 October 2009Copyright © 2008-2009 Nortel Networks.
