Data Module — Type			ppp
	Use the ppp data module for direct point to point TCP/IP connections between DCS
	nodes. This data module associates a link number and destination node with the port
	address and node name for the local node.
	The fields on this form can be changed only when the corresponding port on the
	C-LAN circuit pack has been busied-out.

Common Fields	See Common Data Module Fields (256) for descriptions of fields on this screen that
	are not listed below.
Subnet Mask	The subnet mask is used to specify the network and host portions of the IP address for
	the C-LAN port that is identified in the Port field. The IP address is administered on
	the Node Names screen and is associated with the port location via the node name,
	which is a common field on the Node Names and ppp Data Module screens.

When a new ppp Data Module is created, the system populates the Subnet Mask field with one of three default subnet masks, depending on the node name you enter in the Node Names field. If the node name is associated with a Class C address on the Node Names screen, the Subnet Mask field is populated with the default Class C subnet mask, 255.255.255.0. Similarly, if the node name is associated with a Class A or Class B address on the Node Names screen, Class A (255.0.0.0) or Class B (255.255.0.0) default subnet masks automatically populate the Subnet Mask field.

The default subnet masks correspond to no subnetting. If you want to create subnetworks, you have the option to override the default subnet mask by entering a different subnet mask in the Subnet Mask field. If you enter a subnet mask, the system checks it for validity. For Class C addresses, there are 5 valid subnet masks. For Class B addresses there are 13 valid masks and for Class A addresses there are 21 valid masks.
