- The protocol will allow this. Whether it ever comes to pass is
- another matter. Currently, line busy is returned from the distant
- office for a variety of reasons.

- This approach has merit, but would involve modification of OSPS or
- TOPS or whosever operator services system you are using and a
- corresponding change in the TRs which govern their functions. Another
- aspect of all of this is that "Carrier Connect Time", the period of
- time between your LD company accessing the distant (originating works
- pretty much the same way) LEC, is revenue for the LEC (The LD company
- pays) regardless of whether the call ever completes!
