TL1 Protocol - Brief History And Recommended Equipment

The TL1 Protocol is widely used in network management. It was created to solve several problems, the most significant of which was the incompatibility of devices using different proprietary protocols. Other goals for TL1 protocol included a human readable format and responsiveness to commands.

Because it was designed to be open, TL1 protocol can be considered a precursor to SNMP. So long as a group of devices support TL1, they will be able to communicate, regardless of manufacturer.

But computer-to-computer communication isn't the only benefit of the TL1 protocol. It is also human readable. Although it is structured enough to be parsed, it is also relatively easy for humans to read. This allows a much higher level of understanding with a much lower learning curve than was possible before.

Finally, the TL1 protocol supports responses to commands. A user can issue a command to a TL1 device requesting that it report all of its standing alarms, for example.

Today, TL1 is an aging protocol, but its popularity requires that any high-quality alarm monitoring system must be designed with TL1 protocol in mind.
