Caller*ID and *69

Caller*ID and *69

Post by Dave_C_He.. » Sun, 02 Dec 1990 01:13:00



I heard today that Bell of PA is now offering the Caller*ID feature
for $6.50 per month + $50-$80 for the actual device which displays the
number of the person who is calling you. I may order this service but
I have a few questions first:

1) What areas do the incoming calls have to come from for the number
to be displayed? Do they have to be local, from within PA, from an
area that also has Caller*ID, or will every number show up? What about
long distance numbers? I get most of my calls from Baltimore,
Pittsburgh and Boston. I'm in Philadelphia.

2) Are there many phones on the market that will display Caller*ID
information? If possible, I'd like to get a phone that would display
the number rather than adding a separate box.

I'd also like some information about another feature, the one which
will call back the last person who called you when you press *69.  How
much does this cost? For some reason, I have this feature installed on
my phone, yet I didn't order the service.  I found out about it by
accident. What kind of numbers will this service work with? (again,
within the same state, local,etc.)

Thanks,

 ...regarding caller-id

The call must be from a telephone served by a central office which
participates in the SS7 network.  That includes many 1ESS and 1A-ESS
switches.  Here in NJ, it excludes the newer 5ESS switches, at
present.  Also, it only works intra-lata.  Calls from outside your
LATA will probably be identified only as "OUT OF AREA".

I have been looking for something like this.  I expect to see them
as the service becomes more widespread, but I haven't seen one yet.

Same as caller-id.  It will let you call back anyone who called you,
as long as the call was intra-lata, and intra SS7 network.

Incidentally, this followup represents the state of this technology as
implemented by NJ bell as the posting date.  This is an evolving
technology, and I would expect it to change in several ways: The SS7
network will gradually encompass more of the local switching systems,
and therefore there won't be the large 'holes' in the coverage area we
have now.  Perhaps the information will be carried by the inter-lata
carriers, and will be able to deliver calling numbers on inter-lata
calls, as well as local ones.  Your telco may do things differently
from NJ Bell.

(sigh).  I really oughta put this in a file and just copy it when the
question comes up...  (but will I?  Probably not...)

For Caller*ID information to be displayed, assuming you have
subscribed to Caller*ID and have the Caller*ID box (and therefore your
CO is equipped with the appropriate hardware and software), one of the
following must be true:

1.  The caller must be calling from a phone subtending the same CO you do;

2.  The caller must be calling from a phone subtending a CO which is
equipped with SS7 (common channel signaling system #7), which is in the
same LATA as your CO.

(At some time in the future (beyond 1991), when Interexchange Carrier
SS7 interconnection is available, add:)

3.  The caller must be calling from a phone subtending a CO which is
equipped with SS7, run by a telco which has SS7 connectivity with the
caller's IC, which has SS7 connectivity at the appropriate tandem
switches, and has SS7 connectivity to your telco.

Simple, hey?

In practical terms: Today, you would get the calling number from calls
inside your LATA (in the philly area, generally local calls), from COs
which are SS7-connected (not intuitively obvious which are, but
generally some reasonably high percentage of "major" COs in the LATA
will be SS7-connected before a telco will offer CLASS).

You would not get calling number from Pittsburgh, Baltimore, or Boston.

At some point in the future -- but not before mid-1991, most likely --
you would start getting some calling number delivery from outside your
LATA.  There are so many variables involved that I won't even *try* to
predict where you would and would not get delivery....  save to say
that Pittsburgh would be your best bet (Bell of PA), followed by
Baltimore (C&P of Maryland, different telco but part of Bell Atlantic)
followed by Boston (different Regional Company -- NYNEX).

1. Inter-LATA Caller ID, *67, and *69

-----  On 23 May 1995 21:22:19 -0400, John Boteler  -----

That's very true, but I was talking about *67ers calling from one state
to another.  Your *69 can't give their number out.

Also, I realize *69 won't work right NOW for many LD calls (number would be
unavailable) but my question was actually a futuristic question.  That is,
what will be the case after 12/1/95 when all #'s are sent throughout the
nation.
