SxS had no native DTMF mode.  To provide Touch-Tone in a SxS office
required a translator that listened for DTMF and DP and translated
DTMF to DP. Often only certain line finder groups would be equipped
with such translators because they had to monitor every call to see if
their services were needed.  The translation equipment was pretty
expensive.  This also meant some customers had to have their numbers
changed to get Touch-Tone.

The situation would be different in Southern California, which was
originally all SxS and with growth in the population and network
routing requirments had to have senders in each office to route
outgoing calls. Those were equipped with translation equipment for all
calls, and adding DTMF was not that big a deal.

I think you stored it in the blue box. grin MORE than once, during a phone call, I whistled at something the person on the other end said, and the phone system hung up the call. D*mn that 2600 Hz disconnect tone. I had several friends that could manually whistle at a Bell 103 modem well enough send specific characters. There was also one guy who could whistle up a Bell 212 modem well enough to have it hear one particular string of characters -- nothing meaningful, but absolutely consistent. ***** Moderator's Note ***** I recall my first trouble report on an SF-supervised trunk. I was talking to a guy in Atlanta, and I said "let's see if it responds to 2600 ...". He immediately yelled "Don't put in on the spea... ", and he was gone. Bill Horne Moderator
