[sdiy] New synth DIY site ?

[Paul Schreiber]

    HA! I designed a 672 channel telephone SLIC system (analog phone to T1). Each channel had 6 
    Aromat relays (3 for line, 3 for remote testing). That's 4032 per rack. The average central 
    office had 64 racks or 258,048 relays. 


  Funny, I thought these were usually used in outside plant enclosures, the 5 foot wide white boxes, for doing pair gain out miles away from the CO instead of running lots of copper.

  You need them at *both ends* :)

  SLC-96 and DMS-100 are typical pair-gain channel banks.
