and sent another. The new one does ring the phone (once) much as the old
one did (at one time) but then it crashes just like the old one. I suspect
that if I keep ringing the phone whatever failed completely on the old one
will fail on the new one. I guess people don't even test with mechanical
ringers anymore...

You might be able to adjust the ringer to accept a lower ring voltage.
Check out this link http://www.sandman.com/ringvoltbul.html and scroll down
until you see "Adjusting an old 2500 set ringer to ring on lower
voltages..." It all depends on if your ringer actually has the Bias spring
adjustment. Cheap clone ringers usually don't have it.
Mike Sandman's web site has quite a few devices available that can amplify
the ring voltage if it is absolutely needed.

Waste of time. Buy a new phone with an electronic ringer. About ten
bucks at Wal-Mart.

Like a 1A2 Shoebox KSU - it senses ring voltage and generates it's
own locally to run the tel set and external ringers. The only limit
is how many ringers the 130VAC 20Hz supply in the KSU can drive, and
they do make BIG supplies for big premises.
Anyone know the REN for the input on a Western Electric 400G card?

The current device is making the phone ring but it is crashing thereafter.
The sequence is that I hear a relay click in the Cell2Tel, the phone rings
once, I hear another relay click in the Cell2Tell, and then the Cell2Tel
reboots. It's possible that the residual charge on the ringer's capacitor
is too much for whatever the line is switched back too after the ring
generator. It's clearly a pretty poor design.

I've got two shoeboxes (a 550 and a 550C, with the plastic lift off cover
rather than a hinged door) and none of the 400-type cards installed specify
an REN. And none of the 1A2 BSP handbooks I've got reveal that number,
either. Maybe 400 cards got invented before REN was thought up and WE never
went back to compute or measure that particular characteristic?

A few weeks ago I connected an original 500 set from 1951 to an FXS port
hosted by an 'Internet Phone Jack (IXJ)' card in my asterisk box; it
rang it with gusto. I may try various Command Communications line sharing
boxes too, with increasing ringer loads, until they fail since, oddly,
the documentation that I have is silent regarding ringing capacity.
I seem to remember some sizable magnetics in these boxes, but don't
remember what is on the IXJ card; wouldn't a tuned primary of a step
up transformer in the circuit of a gated oscillator be an adequate
ring generator? The insides of the few VoIP ATAs that I have inspected
don't have much iron on the PCB ;)

HOW DID THE SPREAD OF ISLAM AFFECT THE WORLD?
Among the reasons for the rapid and peaceful spread of Islam was the
simplicity of its doctrine - Islam calls for faith in only one God
worthy of worship. It also repeatedly instructs people to use their
powers of intelligence and observation. Within a few years, great
civilizations and universities were flourishing, for according to the
Prophet, "seeking knowledge is an obligation for every Muslim."
The synthesis of Eastern and Western ideas and of new thought with
old, brought about great advances in medicine, mathematics, physics,
astronomy, geography, architecture, art, literature, and history. Many
crucial systems such as algebra, the Arabic numerals, and also the
concept of the zero vital to the advancement of mathematics, were
transmitted to medieval Europe from Islam. Sophisticated instruments
which were to make possible the European voyages of discovery were
developed, including the astrolabe, the quadrant and good navigational
maps
