[comp.dcom.telecom] Inward Calling

jjc@unix.cis.pittsburgh.edu (Jeffrey James Bryan Carpenter) (07/29/89)

Hi,

I've seen people talk about the operator calling "inward" and have an
idea what this is, but what is the technical description of what it
is?

Thanks,

[Moderator's Note: 'Inward' is simply the operators' positions in a given
location. Operators in other cities, or 'Inward', can be dialed by another
operator, but not by a subscriber. Typically, 'Inward' has a three digit
number of the form 121. For example, to reach Miami, Florida Inward, your
operator would dial 305-121. Your telephone is blocked from dialling codes
of this sort, or 141, which is Directory Assistance, or 131 and 181, which
are operators performing miscellaneous functions.

Why would an operator in one place call an operator in another city? The
most common reason is to seek assistance in getting through to a number in
the distant community which appears to be out of order, or unreachable for
some reason. The operator in one town may wish to have the verifying operator
in another town check on these conditions. Another reason would be to seek
assistance in coin collection on a collect call to a payphone. The distant
operator cannot control the collection or return of coins, so she would
call the local operator there, get the connection to the payphone and have
the operator on that end supervise the collection.   PT]
