Los Angeles Verizon

The La Habra central office was built back in the 1950's as a step-by-step office by the General Telephone Company. It remained a step-by-step office for nearly 30-years. In early 1980, construction started on an addition to the building to make room for a new EAX2B analog electronic switch. In January 1981, the EAX2B was placed into service. At the time, only one of that c.o.'s three existing prefixes were cut over to the new switch, and that was prefix 694. For a few more years, it remained both a step and electronic office. Eventually, the step system was fully retired and the remaining prefixes, 691 & 697, along with a newly added prefix, 690, was cut over to the EAX2B. Over the next few years, prefix 905 was added. In the early 1990’s, the EAX2B switch was retired and was replaced by a 5ESS digital switch, which remains in service to this day.
