L3I to Mojave CA
- I have been in contact with a number of individuals
regarding a L3I carrier cable that was installed from
the east coast to Mojave CA in the mid 60's.
My question to the group is: Does anyone have
documentation as to exact where the eastern terminus
I have have heard three answers:
1. Airmont NY
2. Greenbelt MD
3. Monrovia MD
Now I have my guesses, but it's like trying to see
clearly through a 30-year old coke bottle.
Any references to any documents on-line (or otherwise)
from reliable sources that shed light on this question
would be greatly appreciated.
This is a private history / research account
and is no way related to AT&T in any way other
than the fact I give them money every month.

cable into Greenbelt; the "Greenbelt" thing comes from NASA having
many critical voice & wideband services going to Monrovia on radio &
extending West on the Monrovia-Mojave section of the Airmont-Mojave
cable.Monrovia was the Easternmost Main Station in Md. on the route.
