The TESAMS (Transmission Equipment Supervisory and Alarm Management System) was developed by Siemens during the 1990s in conjunction with Telstra and is believed to be one of the first successful implementations of the OSI CMISE standards for managing transmission networks.  TESAMS is primarily used by Telstra for gathering alarms and performance data from its backbone network.  TESAMS is also used for general environmental monitoring of Telstra sites.

There are some 18 products in the product range, including several multiprocessor modules.  TESAMS equipment is capable of:

• Monitoring digital alarm points use several filtering methods

• Monitoring a range of analog points – voltage (DC & AC), current and temperature

• Operating remote outputs, eg. to switch on a piece of equipment

• Producing regular reports on trends in monitored digital or analog values

• Being locally reconfigured via the TESAMS Local Craft Terminal (LCT) or Field Terminal

• Being remotely reconfigured by the TESAMS Field Terminal or Telstra OSS systems – AMS and DPMS.

TESAMS has been widely deployed within Telstra over the past ten years.  Probably the main factor that has driven this is TESAMS’ ability to provide cost-effective alarm monitoring using a wide range of both digital and analogue service data channels in Telstra’s transmission equipment.  TESAMS is used for the monitoring of both PDH and SDH networks.

Recently TESAMS has been enhanced to work with G.703 interfaces and to support full SDH ring mode operation.

While TESAMS has primarily been designed to interwork with Telstra’s Alarm Management System (AMS) and Digital Performance Monitoring System (DPMS), interfaces can be developed to other management systems.
