Host RJ-11 IP Gateway User Guide, version 23
Configuration Settings and Commands
• Modem Service: Enables modem emulation on both the incoming and outgoing network con-
nections. The target peer (specified in the Phone Number Translation table and configured in
the Protocol Settings page) determines the type of outgoing connection that will be made.
• Outgoing Network Connection: Enables an outgoing connection to the specified host.
• Outgoing Telnet Connection: Enables an outgoing telnet connection to the specified host.
• Modem Service Options: When Modem Service is selected, you may also configure the
Source TCP Port. In most cases, the value used for the source port is arbitrary and you can
leave this field set to 0 for “any”. However, if your server or firewall has specific requirements
you may specify an explicit source port number in the Source TCP Port field. If this port is not
available when the TCP service starts up, an error will occur and the TCP service will reset and
try again.
Phone Number Translation
This table can be used to translate phone numbers into IP addresses or Hostnames. If the attached
device dials one of the specified telephone numbers, the corresponding IP address and port are
used to make the TCP connection. Note that all non-numeric characters except the “,” (comma) in
the phone number are ignored.
When modem emulation is enabled, the Host RJ-11 IP Gateway can detect the phone number from
ATD commands. Although the IP address of the remote host can be embedded directly into the
ATD command, certain devices can't always be easily configured to do this.
FIGURE 6. Host RJ-11 IP Gateway: Phone Number Translation
The Default Translation entry is used if the dialed phone number is not found in the list. (The dial
backup number is not used in the Host RJ-11 IP Gateway.) The phone number table has a number
of features to ease initial configuration. When an attached device dials a number that is not in the
table, the device server creates a dummy entry in the table. This entry will consist of just the phone
number. Until you fill in the remainder of the entry (IP Address/Hostname and Port) and save it,
this entry will not be used.
