Default: TrunkCond
Range: N/A
Format: predefined
alphanumeric
Indicates that trunk conditioning will be done
with ATM network. The PSAX system will gener-
ate an idle data pattern in the payload of ATM
cells to send a signal to indicate a connection fail-
ure.
6-Port Multiserial Module:
If you are using a
6-Port Multiserial module as the ATM trunk, you
must use this value, because the Multiserial mod-
ule does not support OAM.

Unsupp
Indicates that no interworking will be done with
ATM network. The PSAX system will not send a
signal to indicate a connection failure. Do not
choose this value if you want to enable trunk
conditioning.
OAM
Indicates that OAM interworking will be done
with ATM network. The PSAX system will use
ATM OAM cells to send a signal to indicate a con-
nection failure. You can use this value if all the
ATM switches along the connection support ATM
OAM cells.
You must use this value if you selected
Unframed1s in the UpStrmIntrworking field on
the Port and Channel Configuration window of
the module you are configuring. The PSAX sys-
tem does not support upstream interworking of
unframed 1s with a downstream setting of trunk
conditioning.
