What are channel banks?

T1 channel bank - Telco Systems - DCB24Before IP packet-based networks took over the technology world, TDM (time-division networks) ruled the landscape. Though the technology was inefficient and harder to scale, it was extremely reliable and secure compared to today's Internet-connected and cloud-based approach. Many organizations and government sectors still utilize TDM technology or a hybrid approach due to security issues, budget constraints, and applications that don't require further complexity. For example, the Federal Aviation Administration (FAA) has many applications for the airline industry that still utilize TDM and analog technology in the background. Why? because it is extremely reliable in an environment where mistakes cannot happen and its budgets are kept in check for a true return on investment.

Channel Banks were the first digital converters (Multiplexers) for T1, E1, and PRI transmission and TDM based networks. At one time in the past, each phone line was analog with a one-to-one connection, in fact, a single phone line was often shared by several people due to limitations in the number of copper wires that were available. With the advent of TDM and channel banks, a single copper line could now carry multiple phone lines digitally and convert them back to analog for compatibility with existing phones. A channel bank was capable of converting (24 for T1 and 32 for E1) analog phone lines over a single digital line. During the 1970s and '80s, this conversion took place across the entire country to upgrade voice and data networks. Channel banks were in demand and millions were sold and implemented over the years. There are still countless channel banks in service simply because their function is still relevant and continues to provide a return on investment.

Fast forward to the present and many companies and organizations have older equipment that is starting to fail or pressure to expand and test older analog and/or TDM based networks. A channel bank or channel bank alternative is required. Though most channel bank manufacturers have either stopped manufacturing them, gone out of that business, or became too expensive, Pulse Supply has been with you the entire time to provide Channel bank solutions and alternatives.

Many current applications do not require a channel bank based on original manufactured products or specifications. Pulse Supply can help you determine exactly what is required. We have been around for over 25 years and lived through the channel bank revolution and evolution.
