YREKA
(Thanks to AB)

 Yreka was originally built by Pacific Telephone & Telegraph in the 1950s to replace manual toll equipment.  The office eventually was designated a Class 4 "Toll office" under the direct dialing plan in the 1970s and had direct trunk groups to the Redding Class 3 Primary Office.  Yreka was the toll office to the offices along the Interstate-5 corridor at the extreme upper portion of California along the Oregon border.  The tributaries of Yreka were Gazelle, Grenada, Hilt, Hornbrook and Montague.  After the divestiture of the Bell System in 1984, Yreka was removed as toll office classification and became a standalone digital switch homed to the Redding Tandem office.
