A Bit Of History Of Hitachi PBX...

In the mid 1970's, Hitachi Telecom began producing quality PBX systems for use in the Hospitality (USA) market. These systems were designed exclusively for the Hospitality market and provided a great cost reduction solution compared to Western Electric systems provided by the Bell companies.

Through the years the AX Crossbar (1972-1978), the EX Solid State (1978-1983), the DX Space Switch (1983-1987) and the HCX Time Division Multiplex (1987-2004) PBX systems were installed throughout the USA, taking the lion's share of the Hospitality market.

Unlike the Avaya and Nortel PBX systems, which are on the verge of extinction, the Hitachi HCX PBX systems are still very much alive in many hotels. With technology moving to Internet protocol (IP) and a high potential for wireless in our future, Hoteliers have been hesitant to invest in a new Hotel PBX system; that let's face it, is rarely used by the guests, and may become outdated as soon as the installation is finished.

Devera Technologies: A One-Stop-Shop For Hitachi PBX

At Devera Technologies, we offer a one-stop-shop for all your Hitachi needs; from hardware replacement, backup software, and documentation, to services and support for the Hitachi HCX 5100, 5300, 5400 and 5500 models. Even if your current software is running without backups (or not running at all), Devera can fix, grab your current database, and back it up in the form of an "image" on our cloud drive. When (not if) your current hard drive fails, Devera can re-create your data and send you a replacement drive within 48 hours.

We also stock a full inventory of Power Supplies, which you may already know, have a tendency to fail at the worst possible moments. Be assured though, the CPSP, RGMW, CPPW, SPPW, MWPW, or RGPWA can be sent to your property within 24 hours - restoring service quickly and efficiently, should the need arise.

To learn about Power Supplies and Hard Drives (the only major parts that usually fail), click here.

In addition, we offer a service plan that covers everything within the four corners of your Hitachi HCX 5000. The cost is only a dollar per room per month. For larger properties, this minimal cost can even be negotiated!

Devera Technologies Annual Service Plan

When You Purchase An Annual Service Plan With Devera Technologies, You Will Receive The Following:

  • First, we will obtain a copy of your current database which is usually backed up on 3 (4 if 9.0+) "RCD" disks. If you have bad disks or no disks at all - don't fret, we still have quality 5.25 and 3.5 disks that are brand new and still hold data. Once we have the disks with your system data, we will create an image of your hotel and store it for you.
  • On larger systems, we may send out another Hard Drive, copy your database out of your running system, and then send the drive back to Devera for data storage. This is all included within your service plan; you are only responsible for the cost for an on-site technical interaction (if needed).
  • After we have imaged your current database, we will install an analog modem on your Hitachi HCX PBX (if you do not currently have one). From there, all remote work from us is included in your service plan. We will only charge for on-site technical interaction (again - only if needed).
  • Additionally, we stock most Selectsets which are refurbished and carry a guarantee - providing you a 'one-stop-shop' for your Hitachi needs.
