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
1 submenu. 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.
