Receiving Incoming Data Calls
The MCM-4M can receive incoming asynchronous data calls from a PSTN modem.
For simple connectivity (in either the ‘stand-alone’ mode or ‘VPN tunnel’ mode) the establishment of
the incoming asynchronous data call to the MCM-4M can be used to convey the application data
between the originating terminal within the customer’s private data network and the remote terminal
attached to the MCM-4M.
When used in conjunction with the VPN mode, the asynchronous data call to the MCM-4M
can be used to force the MCM-4M to initiate the VPN tunnel back to the customer’s private
TCP/IP data network. In this way, the full bandwidth of the VPN tunnel may be used to
transfer large data files more quickly. Once the VPN tunnel has been opened and the data
transfer commenced the PSTN data call can be released
