S41

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

SWITCH TYPE

Selects the network switch type for dial ser-

 

 

vice.

 

 

0=AT&T 5ESS

 

 

1=Northern Telecom DMS-100

 

 

2=National ISDN-1

 

 

3=NEC

 

 

4-EuroISDN
