Low-Speed Serial Data and Analog/Digital Voice Solutions are In Demand!


What do you do when legacy applications require low-speed serial asynchronous and synchronous data connectivity in a modern era? What about legacy analog and digital T1/PRI voice applications? And what you do when the legacy application requires both serial data and analog/digital voice interfaces? What happened to channel banks and hardware that solved all these applications in the TDM world? Ethernet and IP devastated the legacy world with packets and simplicity. The domino effect rippled through the TDM world worldwide and quickly made serial data and analog/digital voice hardware obsolete. Most of the world's traditional analog voice lines have or are in the process of being dismantled because of the high cost to maintain older technology.

Low-Speed Serial Data and Analog Voice Solutions - Channel Bank Alternative

The equipment and hardware may have disappeared, but many projects, applications, and legacy networks are required to use this older technology. There are many reasons why you would need and use low-speed serial data and analog voice products such as:


  • Legacy networks still in use - there are still networks that older equipment relies on for basic applications. It could be a network that monitors devices no longer made, but not cost-effective to replace.

  • Security issues - Though modern IP-based solutions are technically superior in their capabilities, with complexity comes security risks based on so many options and configuration choices. Legacy equipment was specific to the application and much easier to lockdown.

  • Internet disconnect - In a world completely connected due to the Internet, this can be a disaster for companies and organizations that must provide security for their customers, and being hacked due to a simple mistake can be devastating to all involved. Legacy TDM based equipment provides a natural disconnect from the Internet and it is much harder to breach remotely.

  • Government agencies and networks - Many government institutions, especially those with access concerns still operate on legacy technology for budgetary reasons and more so security requirements. For example, many airports and FAA institutions continue to utilize legacy serial data and voice applications because of their superior uptime, security requirements, and the need for a stable solution in extremely busy public environments.

  • Return on Investment - Many companies and organizations have had legacy networks for many years and it is cheaper to maintain them than replace them with new ones. If you can continue recouping an investment that has paid for itself several times and maintains an acceptable level of quality and functionality, why would you not?
