First, I think that Telephoto Bridging is used for Telephoto Communications. From what I can tell this feature would be one at the switch.
I found some information on telephoto conditioning - please note that this is written in bellsouth manuals so it may not be the easiest to understand.
Telephoto Conditioning provides transmission characteristics suitable for telephotographic communications.
Specifically, Telephoto Conditioning is provided for the control of attenuation distortion and envelope delay distortion
on telephotographic services. The attenuation distortion and envelope delay distortion parameters for Telephoto
(1004 Hz Reference)
Range (Hz) (dB)
500 - 3000 - 0.5 to + 1.5
300 - 3200 - 1.0 to + 2.5
Envelope Delay Distortion
Range (Hz) (mcs)
1000 - 2600 Less than 111
800 - 2800 Less than 181
Now I'm just curious as to what the hell telephotographic communication is. I found a definition and it I'm not sure it makes a whole lot of sense.
Pertaining to pictures transmitted via a telecommunications system.
I hope that helps you out, if not, I hope someone has a little more insight

That may be totally irrelevant, but it made me wonder if that was how they worked. If I missed the mark entirely, I will take my shame.

Dunno but there is also a video bridging service so they may well use that
I did some digging too I found lots of telcos with prices for the telephoto bridging service but no proper description of what it can be used for.
