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

A remote telemetry unit (RTU) that supports SNMP over both LAN and dial-up connections makes it simple to upgrade existing remote sites to SNMP, 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 SNMP remote that uses a dial-up connection to send alarm data to a PPP server, which transmits the data over LAN to the SNMP manager.

This is an immediate solution to bringing SNMP 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 SNMP monitoring with minimum equipment costs.
