Commtel Communications has been selling, installing and servicing these systems since the early 1990's.  Thus, our staff has extensive experience with these systems.  And as such, we still have product distribution lines available

There are still a great many Norstar Meridian and Toshiba digital phone systems in use all throughout Southern California, we know, we installed many of them.  It is true that most of the original dealers have abandoned the technology or they have simply gone out of business.

So, if you are not ready to upgrade to the new VoIP systems and wish to keep using your existing Legacy system, we would be glad to assist you in maintaining them.

Session Initiation Protocol (SIP) has become the common signaling standard for real-time communications for Voice over Internet Protocol (VoIP).  SIP is an open-standard, which enables our customers to seamlessly connect existing Customer Premise Equipment (CPE) with our carrier-class voice network.

Our SIP Trunks work with all IP PBX, Legacy, and Hybrid phone systems.

Commtel has the right solution for you!

For your enjoyment, we offer this brief chronological history of communications for the cities of Corona and Norco, California. 

We believe that in order to fully understand the present and prepare for the future we must know our past.

Whats in a name?
Corona, or South Riverside as it was originally called, was incorporated back in 1896.  Norco was first known as North Corona and it was incorporated in 1964.

Early Map Changes
The area that was to become the cities of Corona and Norco was originally located within the boundaries of the County of Los Angeles- this was way back in the year 1850.  Then in 1853, the County of San Bernardino was formed which included the land of the future cities of Riverside, Corona, and Norco.

In 1883, the new city of Riverside was incorporated.  Then, on May 9th 1893 the County of Riverside was officially formed making the City of Riverside its county seat.  This new county included the area that would become the cities of Corona and Norco.

The Telephone Companies
Beginning on March the 19th 1888, the Sunset Telephone and Telegraph Company installed the first telephone and telegraph lines for the greater Riverside city area.  This company was given the right to erect and maintain a telephone network throughout the city of Riverside, which included the areas known as South Riverside (Corona) and North Corona (Norco).

On December 26th, 1890, the Sunset Telephone Company bought the San Diego Telephone Company lines and switching equipment, thus making the San Francisco based Telephone Company the largest in the state.

During this time, the Sunset Company announced that they would build a Long Distance Telephone line from San Diego to Los Angeles, connecting all other exchanges along the way.  This included the Riverside network, which would allow customers to make long distance calls throughout most of Southern California.

In 1903, the Corona Home Telephone and Telegraph Company was being organized to make use of a telephone company franchise that was recently sold.  On December 6th, 1905, the Corona Home Telephone and Telegraph Company was in operation.

It was during this time that both Corona Home and Sunset Telephone Companies were in direct competition with each other.  The problem was that these two companies were not interconnected to one another.

If you subscribed to the Corona Home Telephone network and your neighbor across the street was a Sunset customer, trying to call them on the phone was a big NO-CAN- DO.

On July the 19th 1906, the Union Home Telephone and Telegraph Company of Los Angeles purchased several of the Home Telephone and Telegraph Companies assets throughout California.

This included the Corona-Norco area of service.  However, the Corona Home Telephone Company continued to operate as a leaser to the Union Company.  This, of course, just added more confusion to the mix.

On September 30th, 1915, the city of Corona filed a complaint against the Pacific Telephone and Telegraph Company (formerly the Sunset Telephone and Telegraph Company), the United States Long Distance Telephone and Telegraph Company, Corona Home Telephone and Telegraph and the Corona Union Telephone and Telegraph Company citing inadequacy of service and unreasonable rates.

The governing body conducting the investigation was the California Railroad Commission (the forefather of the Public Utilities Commission).

The commission found that the two Long Distance companies were not involved in so much as they were only providing long-distance services.  Subsequently, the complaint against those two companies was dismissed.  However, the Corona Home and Corona Union Telephone companies had to answer to the charges.

I am going to spare you the particulars about who was leasing what service from whom and why and who was really trying to set the usage rates for all involved and what finally happened.  The only reason I bring all this up is to make a point: the point being, the more things change, the more they remain the same and history repeats itself.

Not too far into future came the great equalizer-the Pacific Telephone and Telegraph Company of Nevada, a subsidiary of the American Telephone and Telegraph Company (AT&T) which would become the parent company for all of the Bell Systems, or baby Bells.

Eventually, Pacific Bell took over and while the branding has changed a few times over the years, it's still the same parent company, good 'ole AT&T.

Prior to the building craze, begining in the 1980's, the residences and businesses of Corona and Norco received their phone service from Pacific Bell via the Central Office located on 6th Street in Corona.  In the early years, 1947 to be exact, the area code was 213. Then in 1951, everything south of Los Angeles to the Mexican Border and up to the North end of Mono County via the backside of the Sierra Nevada's was 714.  Then in 1992, the Corona and Norco area code was changed to 909.  That lasted until July the 17th 2004 when the area code was finally changed to 951.

Thank you for visiting.  I hope that you found this brief glimpse of history highlighting the role of telephone and radio communications for the Corona and Norco area interesting.
