    Ethernet over Copper is the latest and fastest growing service providing high speed internet and bandwidth. 

    This technology utilizes multiple copper loops that allow your business to achieve speeds up to 50Mbps based on distance to the Central Office (CO). Many customers are switching their T1 lines to Ethernet over Copper because it is faster and cheaper. California Telecom’s Ethernet over Copper product guarantees 99.99% reliability backed up with a solid Service Level Agreement (SLA). Ordering Ethernet over Copper is easy, we handle all of the installation of the copper loops, customer premise equipment, router deployment and setup.  



    California Telecom’s Ethernet over Fiber (EoF) service is a super high-speed and scalable broadband bandwidth solution delivered over a private line. The type of line that is used to deliver business EoF is fiber. Fiber can deliver speeds from 50 Mbps to 10 Gbps. California Telecom will “Hand off” an Ethernet cable to your network, making connecting to the Broadband Internet simple and efficient.  



    Fixed wireless is the operation of wireless systems that connects two or more fixed locations, building with a radio or other wireless link. Usually, fixed wireless is part of a wireless LAN infrastructure. Fixed wireless data links are often a cost-effective alternative to leasing fiber or installing cables between the buildings. California Telecom offers free consultations and will set up and optimize your fixed wireless network between your offices if this is the best solution for your company.  



    California Telecom offers one of the few true dedicated symmetrical 1.5 Mbps point to point T1 connections to the internet available in the marketplace today. California Telecom owns, operates and manages the connection with end to end Cisco hardware from your point of business all the way to our data center housed at One Wilshire, Los Angeles – the premier communications hub of the Pacific Rim. Your business is then placed directly onto a high bandwidth, high capacity connection to the internet. California Telecom maintains, manages and assumes full responsibility and control over the connection route it provides. This allows California Telecom to guarantee the bandwidth, latency and reliability to a degree that is not possible with other T1 providers.  



    California Telecom will bond several dedicated T1 lines to provide increased bandwidth up to 9Mbps to meet with the demands of your company without the cost of implementing a full T3 solution. T1 lines can be added or removed at any time to remain flexible. Bonded T1 technology is perfect for hosting services such as application and web servers from a central headquarters location to remote office locations. By increasing the bandwidth at the headquarter location all remote offices benefit from the added performance and reliability.

    • MPLS


    • Managed Firewall

    MPLS Multiprotocol Label Switching (MPLS) is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links (paths) between distant nodes rather than endpoints. MPLS can encapsulate packets of various network protocols. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL.

CaliforniaTelecom customer service is a shining example of what every service provider should offer. Our IT Production Services division is fully dependent on the internet. We've been a California Telecom customer for at least 7 years, and I'm amazed with the support team and level of service. I recommend California Telecom to everyone I know, who has internet service and to those who need it. Truly the right choice!

When I was opening my new business, I spoke to many different providers but I couldn't find a match with any of the other providers regarding quality, price, and great service. California Telecom has been a great provider with quick and personal service. I highly recommend California Telecom and the solutions they offer!
