Chapter 7. Protocol Options

near- and far-end DCE need to be configured to use the BONDING mode 1 protocol. Also, if the second B channel number is different from the first B channel, it is important that the 7-digit LDN is programmed in the answering unit. The BONDING mode 1 protocol negotiation phase has numerous timers to allow for transmission delays due to satellite hops, international calls, etc. The timers may be adjusted if necessary by entering into the BONDING mode

1submenu. Figure 7-2 illustrates the menu path for setting the timers.

BONDING Mode 1 Protocol Menu Tree

The timers are defined as follows:

TXINIT

This option specifies the length of time the originating endpoint attempts to detect the BONDING negotiation pattern from the answering endpoint before deciding the BONDING call has failed. In general, this timer value should be left at the factory default setting of 10 seconds. Values of 1, 2, 5, 10 (default), 20, 50, 100, and 200 seconds may be selected.

TXFA

This option specifies the length of time both endpoints attempt to detect the BONDING frame pattern when a call is connected before deciding the BOND- ING call has failed. This timer value 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 timer so that it matches TXADD01. Values of 1, 2, 5, 10 (default), 20, 50, 100, and 200 seconds may be selected.
