Timing to Establish a Connection
o A connection is established when a connection request is received from the SMDR
terminal.
Timing to Output Billing Information
o Billing information is output when a polling request is received from the SMDR terminal
connected to LAN.
Timing to Release the Connection
The connection is released when the SMDR terminal does not receive data from the
