Accept calls from all IP addresses or Accept calls from only the following IP addresses – Allows the user to
selectively accept inbound calls based on the source IP address.
Data Management Parameters
Termination Character – The user may define a termination character that will cause any buffered characters to be sent.
In conjunction with the Termination Character parameter, the user may define the length of a block check sequence in
Block Check Length that follows the termination character. This will ensure that LRC or CRC characters following the
Termination Character are included in the same outbound message.
Transmit Timer – The user may define a timeout value that will cause any buffered characters to be sent.
Maximum Block Size – The user may define a block size threshold that will cause buffered characters to be sent.
Session Timer – Forces a hang up after a specified period of time without regard to any activity that may be in process.
This feature is designed to guard against sessions that are inadvertently left active and could therefore create large
network usage fees. When set to zero this timer is disabled.
Inactivity Timer – The user may choose to configure the PAD to terminate a connection if no inbound or outbound data
traffic occurs for a defined period of time.
Note : Any Data Management Parameter may be disabled by setting its value to zero.
