[mod.telecom] Selective call waiting feature on GTEDS-5?

crg@UW-JUNE.ARPA.UUCP (05/23/86)

Can anyone tell me if I should be able to have the selective call waiting
feature discussed here previously on a line served by a GTEDS-5 (206-822-)?
The ability to block call waiting signal during data calls is what I'm
interested in.

The service rep at GTE/NW says they don't offer the feature but I'm
wondering if they don't know they have it or really don't have it.
If there are more specific questions I should ask GTE about the
CO gear please advise.  Thank you.
