[comp.dcom.telecom] Answer Detection and Supervision

K_MULLHOLAND@unhh.unh.edu (KATH MULLHOLAND) (03/10/91)

Yesterday I spent an hour with a representative from HOMISCO, a
company which specializes in answer *detection* devices for hotels.

Apparently, their little black box is attached between our LD trunks
and our system 85, and monitors the lines for certain soundsthat
indicate the call has been completed.  HOMISCO claims a 90% accuracy
rate.  The box only monitors calls that last less than a set
threshhold -- two minutes maximum.

Since we resell to students here at the University of New Hampshire, I
an interested in answer detection to reduce complaints of bills for
uncompleted calls, and to capture revenue on short calls.

Does anyone out there have experience with HOMISCO to share?

How is their box likely to interface with our non-analog trunks?  We
have three T-1's, and the salesperson said they interface at the RJ.
Is this possible with T-1 without degrading or jeopardizing the
service?

Last, are there people out there who can give the current status of
answer *supervision*.  If our CO has a #5 ESS, is it likely that we
could get answer supervision signals on less than a four-wire circuit?

If anyone would like more details on this sales call, I'll be happy to
provide what information I have.
