TXDEQ
This option specifies the length of time both endpoints attempt to
equalize the network delay between the bearer channels before
determining the BONDING call has failed. Values of 1, 2, 5, 10,
20, 50 (default), 100, and 200 seconds may be selected.
TANULL
This option specifies the length of time the answering endpoint
attempts to detect the BONDING negotiation pattern from the
originating endpoint before aborting to clear channel mode. In
general, this timer value should be left at the factory default set-
ting of 10 seconds. However, it may be necessary to shorten this
timer if the DTE equipment connected to the ISU also has timer
constraints for completing non-BONDING parameter negotia-
tion. Values of 1, 2, 5, 10 (default), 20, 50, 100, and 200 seconds
may be selected.
TCID
This option specifies the length of time both endpoints attempt to
negotiate an agreeable value for bearer channels and channel
capacities before determining the BONDING call has failed.
Select from values of 1, 2, 5 (default), 10, 20, 50, 100, and 200 sec-
onds.
Async. Rev.
This option specifies the negotiation revision for asynchronous
BONDING. Rev. 1 specifies multi-vendor compatible negotiation.
Rev. 0 specifies ADTRAN proprietary negotiation. This option
has no effect on synchronous negotiation.
V.120
The V.120 protocol is a CCITT compliant rate adaptation method
providing DTE service between the ISU 2x64 and other V.120
compliant devices at rates less than the 64 kpbs ISDN bearer
channel rate. V.120 supports both synchronous and asynchro-
nous DTE rates. See Recommended Operating Protocols on page 6
for available V.120 rates. Figure 6-21 illustrates the menu path for
selecting V.120.
