80 System descriptionAlternatively, the PC application, pcANYWHERE©, can be installed in hostmode on the TM 3.1 PC to provide remote access to any PC with a modem.The remote user dials the TM 3.1 PC which contains the required IP Trunk3.01 (and later) data (whether stored locally or on an TM 3.1 server). Onceconnected, the remote user can perform any operation available to that PC.Remote AccessRemote Access is supported on the MMCS IP Gateway. Remote Accessallows a MAT user, such as Nortel Networks support personnel, with no ITGdata to manage the ITG card remotely.The PC application, pcANYWHERE©, can provide remote access to anyPC with a modem. The remote user dials the MAT PC which containsthe required ITG data (whether stored locally or on a MAT server). Onceconnected, the remote user can perform any operation available to that PC.Per-call statistics support using RADIUS ClientThe IP Trunk 3.01 (and later) architecture isolates the TLAN networkinterface from the system. However, the system does not have direct accessto per-call statistics on the voice quality of the call. These statistics areimportant for the purpose of the following:• make sure the network is providing the contractual service level• solve help desk inquiries or refund "bad call" charges• identify network problems and track network performanceIP Trunk 3.01 (and later) uses a Remote Authentication Dial In User Service(RADIUS) client to transmit these statistics from the IP trunk card to anetwork device:• The IP trunk card sends a Start record when a call begins.• The IP trunk card sends an End record when the call is released.• The End record contains QoS information and the amount of data sent.• Both records contain the Called and Calling Party numbers for callidentification.• The TM 3.1 Call Accounting application does not correlate RADIUS percall statistics with the Meridian 1/CS 1000M CDR.A network "listener" receives Start and End messages and stores the data.Applications can retrieve the stored data for processing and presentationto the user.Nortel Communication Server 1000IP Trunk FundamentalsNN43001-563 02.01 StandardRelease 5.5 21 December 2007Copyright © 2007, Nortel Networks.
