BOND TXFA
Specifies the number of seconds both end-
points attempt to detect the async BOND-
ING frame pattern when a call is connected
before deciding the async BONDING call
has failed. When operating with other man-
ufacturer's async BONDING equipment it
may be necessary to lengthen this timer so
that it matches TXADD01.
0 to 255, 10 sec is default.
S42
BOND TXADD
The number of seconds both endpoints wait
for the additional call to be connected at the
end of negotiation before deciding the async
BONDING call has failed. When dialing
overseas it may be necessary to lengthen this
timer to allow for slower call routing.
0 to 255, 50 sec is default
S43
BOND TXDEQ
The number of seconds both endpoints at-
tempt to equalize the network delay be-
tween the bearer channels before deciding
the Async BONDING call has failed.
0 to 255, 50 sec is default
S44
BOND TANULL
The number of seconds the answering end-
point attempts to detect the Async BOND-
ING negotiation pattern from the
originating endpoint before aborting to clear
channel mode. It may be necessary to short-
en this timer if the DTE equipment connect-
ed to the Express XRT also has timer
constraints for completing non-BONDING
parameter negotiation.
0 to 255, 10 sec is default
S45
BOND TCID
The number of seconds both endpoints at-
tempt to negotiate agreeable values for bear-
er channels and channel capacities before
deciding the async BONDING call has
failed.
0 to 255, 5 sec is default
S52

vice.
