  Does some one have figures in re the economics of the SLC-96 ? I don't
remember having seen any hard numbers in TELECOM Digest.

  I mean, how much does a SLC-96 cost (equipment + installation +
maintenance) to the telco? And more to the point, how does this cost
compare with (equipment+installation+maintenance) cost of 96
local-loop pairs ?

  Or perhaps, at what point does this break even ... a community of 96
subscribers X (??) miles away are better served by SLC-96 than 96 pair
cable.

  Another question, I recently read about an SLC-120 in an Indian
telecom magazine. They were referring to the US. Any SLC-120s in
service ?
