Table 3-16.

External Modem (COM Port) Options (2 of 2)

Alternate IP Address

Possible Settings: 001.000.000.000 – 223.255.255.255, Clear
Default Setting: Clear (000.000.000.000)

Specifies the Alternate IP Address for the COM port when the alternate phone directory
is used. If this configuration option is not configured (i.e., it is zero), the COM port’s
primary IP Address is used when the alternate telephone directory is used.

Display Conditions – This option does not appear if External Modem Commands is
set to AT. Only in effect when the COM port is configured as a network
communication link (Port Use is set to Net Link, see Table 3-15,

Communication Port

Options

).

001.000.000.000 – 223.255.255.255 – Shows the COM port’s Alternate IP Address,
which you can view or edit. The first byte (i.e.,

nnn.255.255.255) can be any number

from 001 through 223, excluding 127. Remaining bytes (i.e., 223

.nnn.nnn.nnn) can be

any number from 000 through 255. Leading zeros are required.

Clear – Clears the Alternate IP Address for the COM port and fills the address with
zeros ( i.e., 000.000.000.000 ).

Alternate Subnet Mask

Possible Settings: 000.000.000.000 – 255.255.255.255, Clear
Default Setting: 000.000.000.000

Specifies the Alternate Subnet Mask for the COM port when the alternate phone
directory is used.

Display Conditions – This option does not appear if External Modem Commands is
set to AT. Only in effect when the COM port is configured as a network
communication link (Port Use is set to Net Link, see Table 3-15,

Communication Port

Options

).

000.000.000.000 – 255.255.255.255 – Shows the subnet mask for the COM port, which
you can view or edit.

Clear – Clears the subnet mask for the COM port and fills the address with zeros
( i.e., 000.000.000.000 ). When the node subnet mask is all zeros, the IP protocol creates
a default subnet mask based upon the class of the IP address:
Class A: 255.000.000.000, Class B: 255.255.000.000, or Class C: 255.255.255.000.
