In general, this timer value should be left at the factorydefault setting of 10 seconds. Select from values of 1, 2, 5, 10(default), 20, 50, 100, and 200 seconds.TXFAThis option specifies the length of time both endpoints attempt todetect the BONDING frame pattern when a call is connectedbefore determining the BONDING call has failed. This timervalue should be left at the factory default setting of 10 seconds.However, when interoperating with other manufacturers’BONDING equipment it may be necessary to lengthen this timerto match TXADD01. Values of 1, 2, 5, 10 (default), 20, 50, 100, and200 seconds may be selected.TXADD01This option specifies the length of time both endpoints wait forthe additional call to be connected at the end of negotiationbefore determining the BONDING call has failed. The factorydefault setting of 20 seconds is sufficient for most calls to gothrough, although when dialing overseas it may be necessary tolengthen this timer to allow for slower call routing. Values of 1, 2,5, 10, 20, 50 (default), 100, and 200 seconds may be selected.3=CONFIG1=Netw. options2=DTE options3=Protocol4=Quick setup5=Security6=Remote Config1=Clear Channel2=BONDING mode 13=V.1204=V.1105=DSU 57.6 ASYNC6=T-LINK7=SAP8=FALLBACK9=PPP async-sync1=TXINIT2=TXFA3=TXADD014=TXDEQ5=TANULL6=TCID7= Async.
