Appendix D. S-Register List

 

 

 

S42

BOND TXADD01

The number of seconds both endpoints wait for the

 

 

additional call to be connected at the end of negotiation

 

 

before deciding the BONDING call has failed. When

 

 

dialing overseas, it may be necessary to lengthen this

 

 

timer to allow for lower call routing.

 

 

Range = 0 to 255, 50 sec is default

S43

BOND TXDEQ

The number of seconds both endpoints attempt to

 

 

equalize the network delay between the bearer channels

 

 

before deciding the BONDING call has failed.

 

 

Range = 0 to 255, 50 sec is default

S44

BOND TANULL

The number of seconds the answering endpoint attempts

 

 

to detect the BONDING negotiation pattern from the

 

 

originating endpoint before aborting to clear channel

 

 

mode. It may be necessary to shorten this timer if the

 

 

DTE equipment connected to the ISU 128 also has

 

 

timer constraints for completing non-BONDING para-

 

 

meter negotiation.

 

 

Range = 0 to 255, 10 sec is default

S45

BOND TCID

The number of seconds both endpoints attempt to

 

 

negotiate agreeable values for bearer channels and

 

 

channel capacities before deciding the BONDING

 

 

call has failed.

 

 

Range = 0 to 255, 5 sec is default

S46

V25 MODE

Selects the type of V.25 bis dialing used.

 

 

0

= Asynchronous V.25

 

 

1 = HDLC V.25

 

 

2 = BISYNC V.25

 

 

3

= HDLC with flags V.25

S47

RS-366 TIME

Determines the amount of time the RS-366 port will wait

 

 

for EON or inactivity to terminate a dial string before

 

 

dialing a number.

 

 

0

= Wait for EON only

 

 

10= Wait for 1 second or EON

 

 

20= Wait for 2 seconds or EON

 

 

50= Wait for 5 seconds or EON

 

 

100=Wait for 10 seconds or EON

 

 

200=Wait for 20 seconds or EON

S50

LINE MODE

Selects the operating mode of the ISU 128.

 

 

0

= Dial service (switched service)

 

 

1

= Leased service (non-switched service)
