handle:

a.) IP packet with F0-FD address , "To" Node is repeater's.
b ) IP packet with F0-FD address, "To" Node is not repeater's.
c ) IP packet with F0-FD address, "To" Nod e & Call is repeater's.
d.) IP packet with FE address, "To" Node is not repeater's.
e.) IP packet with FE address, "To" Node is repeater's.
f.). IP packet with FE address, "To" Node & Call is repeater's.
g.) IP packet with FE address, "From" Node is repeater's.
h.) NSI packet, an F0-FD address, with command or control text.

The corresponding situations are these:

a.) Repeater is last or only link in a linked chain
b.) Repeater is a middle link in a linked chain
c.) Repeater itself is the final target of the packet
d.) Packet is for another server, unless case g below.
e.) Repeater is last or only link in a linked chain
f.) Repeater itself is the final target of the packet
g.) Repeater is a beginning link in a linked chain
h.) Repeater itself is the final target of the packet

The above list does not cover the non-IP header packets which might be in use by a local area net. It also assumes the "source route" option, mentioned in (19) above, is not in use.

26. For a station to automatically return a packet over the path on which it came, the following steps are necessary (IP protocol is assumed):

a.) Exchange source & destination node numbers
b.) Receive and transmit using standard FE calling address.

The repeater (or non-repeater) which delivered the packet will automatically pick it up and retrace the path.

The Internet Protocol also provides for a "return route" option in the header. It could be used on a connect packet to indicate the path to be used in responding.

27. Direct connect stations using IP protocol can use "NET 00 00 00" as the network node address. NET is decimal 44.
