MCC-545C PACKET DATA RADIO

12/2000

TTR –

Time-to-retransmit in minutes (default is 20 minutes); i.e., the message is
retransmitted if it has not reached its destination within this time frame.

NUP –

Neighbor-up threshold (default is 20 acquisitions); the number of times a Station
must hear from another Station within a one minute time interval before it
becomes a neighbor.

NDOWN –

Neighbor-down threshold in minutes (default is 20 minutes); if there is no
communication with a neighboring Station within the set time, the route to that
neighbor is ignored. Setting NDOWN to 0 maintains the routing to the neighbor
indefinitely.

RDOWN –

MASTER OPERATION ONLY - Remote-down threshold in minutes (default is
1,440 minutes); if there is no communication with a Remote Station within the set
time, the Remote is declared down and is removed from the Remote table.
Setting RDOWN to 0 keeps a Remote defined indefinitely.

OTL –

Outstanding text limit (default is 20 texts); the number of messages a Station is
allowed to send to another Station without an end-to-end acknowledgment.

CONNP –

MASTER OPERATION ONLY - Connectivity message precedence (default is 1
precedence); information on changes in the connectivity table is given highest
precedence (automatic feature).

ETEAP –

End-to-end ACK message precedence (default is 0 [zero] precedence); the
acknowledgment of a message when it reaches its final destination is given
highest precedence.

HTO –

History file timeout in minutes (default is 10 minutes); maintains information for
duplicate filtering.

TEXTL –

MASTER OPERATION ONLY - Text size in segments (default is 32 segments).

FLOODP –

MASTER OPERATION ONLY - Partial "flooding" precedence level (default is
A precedence). Messages of this precedence level and above are transmitted over
all routes of minimum length; messages below this precedence are not sent over
all minimum length routes, but are sent only over the routes where the shortest
transmit queues exist.

MBHOP –

meteor burst link hop weight (default is 1 hop). Defines the number of network
hops to associate with a meteor burst Master Station link when determining the
minimum path to use in routing a message. MBHOP should be set high enough to
prevent a meteor burst Master Station link to be chosen over a line-of-sight
Remote to Remote link in a network that is predominantly line-of-sight.

INF –

MASTER OPERATION ONLY - Infinity hop quantity (default is 8 hops).
Defines the width of the network in hops plus one to determine when connectivity
