Bell SOP no longer requires registration and RE numbers, as I too discovered
earlier this year when I traded in my Bell set and replaced it with a
ten-year-old Stromberg 2500D (which was culled from a junkyard and works
better than the three-year-old Bell set ever did).  The ESS offices, at
least, seem to be able to handle quite a range of ringer current loads,
and the company claims to be able to gauge the ringer load on the line
fairly accurately.  However, although I'm not familiar with the method
used for such measurements (I need to research that when I have time),
I can tell you that I'm not very impressed by it.  A few months ago, I
lost about three weeks of phone service when the tip conductor opened up
somewhere between the central office and my dropline.  The explanation
for the lengthiness of the outage could easily occupy several paragraphs,
but suffice it to say that I had numerous conversations with Repair Service
dispatchers and various people in the business office in the interim.
For the last two weeks of the ordeal, the open reduced to a noisy inter-
mittant.  This brought about an interesting mode of operation -- average
loop current was high enough to hold the line, and remarkably, the C. O.
DTMF decoder even worked (more or less) properly; it was just impossible
to carry on a conversation.  At this point, a service representative
(who surely intended it as a kindness) decided I needed a break, and so
rather than dispatching a repair truck when she was certain the trouble
MUST be in my phone (it's a customer-owned set, you know, and they
ALWAYS cause  trouble) she "tested" it from her console as she spoke
to me (on another line, obviously).  Her testing revealed not only that
the connection was solid [:-)] but also that I had THREE (count 'em,
three!) sets plugged in.  Oh well, what's 200% error, anyway?  I guess
the instrument's measurement tolerance is GMV (that's Guaranteed Minimum
Value for all you non-hardware hackers).  It seems likely that an
instrument like that will "detect" as many nonexistant devices as
anything else. The impasse was finally broken by the intervention of,
of all things, the CWA strike.  During the strike, you see, when all
the flunky employees are out of the office, they reassign some white-
collar types to hold down the fort.  Consequently, on my last call to
Repair Service, I got some engineer (I guess) who understood what I was
telling him and faithfully wrote it all down.  (By that time, I had
traced the line as far back as I could without seriously endangering
my health.)  Voila!  The following day, the lead was finally repaired.
This, Ladies and Gentlemen, is the kind of service for which the phone
companies feel justified in charging us an extra fifty bucks a month!

Feel like writing your Congressman?  You have my blessing.
