A  Screens Reference
When adding an access endpoint with the ITC administered as restricted, its 
associated port can be a channel from a DS1 circuit pack with Zero Code Suppression 
administered as zcs or b8zs.
For an existing access endpoint, ITC can only be changed from restricted to 
unrestricted if its associated port is a channel of a DS1 circuit pack with its Zero Code 
Suppression field...

Data Module — Type ethernet 
Use the ethernet data module type to define an interface between port 17 on the 
C-LAN board and the LAN. This data module associates a link number and extension 
number with the C-LAN port address.

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.

The valid subnets for each Class of address are:
Notice that all 5 valid Class C subnet masks can also be valid Class B or Class A 
subnet masks, and all 13 valid Class B subnet masks can also be valid Class A subnet 
masks.
For example, 
255.255.255.224 is a valid subnet mask for all three address 
classes. It allows 6 (2
3-2) subnetworks for Class C addresses, 2046 (211-2)...

Destination DigitsUsed to enable access to the correct trunk group at the far end of the connection. This 
is typically the trunk access code (TAC) plus the extension of data module on the far 
end. If you use just the extension, then you must administer UDP and AAR route 
patterns to access the correct trunk group. 
Destination Node NameName of the node at the far end of this...

Data Module — Type procr-intf (used for BX.25 connections with the si model)
Use the procr-intf data module type to define an interface between the Processor 
Interface circuit pack and the DS1 facilities carrying the X.25 data for the connection 
to far end switch. This data module associates a link number with a physical channel 
number and extension number for the PI port...
