It seems to have been built purely for this purpose, as the cable leg connecting CMC to the L-3I transcontinental is too long to be powered just from the ends. The station is still in use for the fiber route overlaid on the L-1 cable ROW. text/html 2025-03-31T01:35:55+00:00 Anonymous (anonymous@undisclosed.example.com) https://td-2.org/facilities/cable/ca_coaxial_repeater?rev=1743384955 CA Coaxial Repeater This is a stub page for a coaxial cable-type repeater station in California along I-10. My assumption is that it's a L-4 or L-5 route but that needs to be confirmed. It is now colocated with a modern precast concrete hut for fiber regenerators, and is very close to a Sprint fiber regenerator called Redcloud. text/html 2025-05-27T16:23:55+00:00 Anonymous (anonymous@undisclosed.example.com) https://td-2.org/facilities/cable/colorado_fountain_mystery_repeater?rev=1748363035 Colorado Fountain Mystery Repeater In Colorado, along the I-25 corridor south of Denver, there are several buildings that appear (based on various evidence, sometimes only circumstantial) to be telephone cable repeaters.

There is no microwave tower at Kingman, and it has not received any of the additional underground buildings common at some other L-3I stations. There is just the surface entry structure (in its original white and blue paint), ventilation, and a hoistway. text/html 2026-04-06T02:14:46+00:00 Anonymous (anonymous@undisclosed.example.com) https://td-2.org/facilities/cable/l-3i_repeater_l1e?rev=1775441686 L-3I Repeater L1E This L-3I repeater, east of Socorro, is pretty much the same as all the others.

It is located some distance south of Tucumcari. Unlike most of the L-3I undergrounds in the West, it has a rather modern and relatively large surface building, suggesting that it's seen significant reuse for some type of equipment.
