System Configuration and Operation Cross-Connecting WAN Time Slots
Figure 3-28. Cross-Connect Circuit Type Selection
TC
You can define the pattern to be transmitted on a cross-connected circuit if one of the circuit’s
two WAN links fails. This is known as Trunk Conditioning (TC), and the available selections
depend on the Type column setting.
If the Type setting is
d
(data), no TC choice is available and the system automatically shows
moos
. An example of this is shown as Figure 3-28.
If the Type setting is
v&s
(voice with signaling), the TC choices are shown in Figure 3-29.
They are as follows:
user
(user-defined bit pattern),
e&m
(trunk signaling),
fxsl
(foreign
exchange station-loop-start),
fxsg
(foreign exchange station ground-start),
fxsd
(foreign
exchange station-defined network),
plar
(private-line automatic ringdown),
dpo
(dial-pulse
originating),
fxol
(foreign exchange office loop-start),
fxog
(foreign exchange office
ground-start),
fxod
(foreign exchange office-defined network),
dpt
(dial-pulse terminating)
and
mrd
(manual ringdown).
If you choose
user
, also enter a two-digit hexadecimal code for the bit pattern to be sent in
each direction. Each digit can be from
0
to
9
or
a
to
f
. Figure 3-30 shows a typical signaling
bit pattern entry screen.
