80 System description
The PC application, pcANYWHERE©, can provide remote access to any
PC with a modem. The remote user dials the MAT PC which contains
the required ITG data (whether stored locally or on a MAT server). Once
connected, the remote user can perform any operation available to that PC.
Per-call statistics support using RADIUS Client
The IP Trunk 3.01 (and later) architecture isolates the TLAN network
interface from the system. However, the system does not have direct access
to per-call statistics on the voice quality of the call. These statistics are
important 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 performance
IP 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 a
network 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 call
identification.
• The TM 3.1 Call Accounting application does not correlate RADIUS per
call 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 presentation
to the user.
A RADIUS client on the IP trunk card allows per-call statistics of the IP
network call to be sent from the cards to a network listener. The client is
based on RFC2139, which defines the accounting portion of the RADIUS
protocol. The IP trunk card uses the authentication algorithm based on
RFC1321.
Configuration
Use TM 3.1 to configure the following RADIUS parameters:
• enable/disable RADIUS record generation
• IP address of the RADIUS listener
• IP port number of the RADIUS listener
