Chapter 6. Configuration

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.
