[comp.dcom.telecom] "110" Code

DREUBEN@eagle.wesleyan.edu) (DOUGLAS SCOTT REUBEN) (09/28/90)

In response to Bob Goudreau's posting about a special code for "976"
like numbers (sorry for the terrible oversimplification of your
posting...):

Just in case anyone cares, I think 110 is used to call back an
operator on an operator assist call IF you have three way-calling.

See, let's say I make a operator assist call, and after the call is
over, I want to talk to the operator again (perhaps for "time and
charges"). If I have Three-Way calling, any FLASH that I generate with
the hookswitch or whatever will usually cause me to get a three-way
dial tone, and no matter what I won't be able to flash the operator on
the initial leg of my call.

SO, some Bell Co.s (or psuedo-Bell Co.s) use the code "110" to flash
an operator. You basically get the three way tone, dial "110", and
then you are dropped back to the initial call and an operator will
come on the line shortly. (It is similar to dialing *70 [Call Waiting
Block] using three-way calling, after you dial *70 your calls are
blocked and you are dropped back down to your initial call. )

I've noticed that DMS offices don't seem to support this, but older
1/1A ESS offices seem to have it. (I've never had the opportunity to
try it on a 5ESS ... anyone know if it works there?)

Another reason for not using "110" that I'm suprised no one has
brought up in the last burst of replies: in most modern switches that
I've used, dialing "11" is the functional equivalent of dialing "*".

(PS: Yet Another Reason the Universal Card PIN is not on the card --
you can have it changed with a phone call.)
