c) Blocking of Trunk Call through Other PBXs and How to Override It
To prohibit a TIE line call to go through PBX-2 for making a trunk call, if PBX-2
is Panasonic Hybrid IP PBX (e.g., KX-TDA100 or KX-TDA200), PBX-2 should
disable the trunk group of the outgoing call from PBX-2 against the COS of the
trunk group of the incoming call to PBX-2 (
like the programming example shown below. TRS/Barring applies to a TIE line
call on a COS of the trunk group of the incoming call basis. To override this
prohibition, access the DISA floating extension number of PBX-2 and enter a
verified code to change to the COS temporarily.
