The time-to-live parameter input is truncated to a 10-minute boun¬da¬ry.

If you enter 60 through 69, the TTL for the next message will be 60

minutes. A resultant value of 0 (parameter range 0 – 9) means the message

will never time out.

TTR – Time-to-retransmit in minutes (default is 30 minutes); i.e., the

message is retransmitted if it has not reached its destination within this

time frame.

NUP – Neighbor-up threshold (default is 2 acquisitions); the number of times

a Station must hear from another Station within a one minute time interval

before it becomes a neighbor.

NDOWN,xx,yy – Neighbor-down threshold in “xx” minutes (default is 120

minutes), and “yy” is the number of times a Station attempts to

communicate with a neighbor before attempting to talk to another Station;

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 – Remote-down threshold in minutes (default is 2 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 Station 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 2 precedence);

the acknowledgment of a message when it reaches its final destination is

given highest precedence.

HTO – History file timeout in minutes (default is 5 minutes); maintains

information for duplicate filtering.
