5.8.9.7. Configuration Notes 
The following notes apply to all applications (grounding/flash to
trunk, suffix dialing after grounding, and picking up after a consultation
hold):
- This setting is valid for BWMSCH lines. The same basically applies to other lines (see PTIME). In PTIME TBLK (corresponds to CIRCIDX in TACSU) check that BWMSCH L3 = 240 ms and L4=120 ms; These may have to be adapted to fit the line that is connected.
- You must set OVRA in the COT of the trunk circuit.
- The application only functions when the trunk circuit for the outgoing seizure is reached over the CO (WABE) digital analysis result.
For grounding and flash to the line, the following applies:
- Configure the digital analysis result OPROVR in WABE.
To pick up a consultation hold with TC-SL coupling, the following applies:
- Configure the digital analysis result PUEXT in WABE. In the COT of the trunk circuit,
you
must set CONS (COT OVRA is not needed for the feature alone).
The OpenScape 4000 no longer has the COT CONS; a replacement will follow later.
To allow suffix dialing, the following applies (for example, after OPROVR):
- You must set USD in addition to OVRA in the COT.
