A Versatile Remote Creates a Smooth Upgrade Path for Existing Remote Sites

A remote telemetry unit (RTU) that supports both LAN and dial-up connections makes it simple to upgrade existing remote sites to LAN-based monitoring, even if LAN access is not immediately available.

Originally, this site was monitored by a legacy remote using a dial-up connection to report to its master. This can be immediately replaced with an advanced remote that uses a dial-up connection to send alarm data to a PPP server, which transmits the data over LAN to the master.

This is an immediate solution to bringing LAN-based monitoring to the site. Later, when the site is brought into the network, the same remote can be quickly transferred to LAN as a primary connection with a minimum of provisioning and without disconnecting alarm inputs. The dial-up connection is still retained as a backup secondary connection in case of LAN failure. This process creates a smooth transition to LAN-based monitoring with minimum equipment costs.
