|  | Service Node The Open Telecommunications Service Node, Open SN, is a cost effective means of introducing IN services into non-IN networks. It has the features of a full IN implementation in a single platform and connects to the network using normal call handling signalling. The Open SN is different to most service nodes. It has been designed from the ground-up as an IN component. The Open SN functions are easily migrated to a full IN architecture - there is no need to re-implement services to provide higher capacity and a more distributed architecture. All IN functions in a single platform The Open SN incorporates all the functions of the Open SCP and the Open IP, and the call handling functions normally done by a Service Switching Point (SSP). The latter include: IN call models for originating and terminating calls Trigger detection and processing Call gapping and service filtering Production of call detail records (e.g. for billing) Full IN call handling The Open SN handles calls using the same powerful service logic and service data functions as the Open SCP enabling future migration to a full IN architecture. Easy network connection The Open SN connects to the network using the normal call handling protocol, the ISDN User Part (ISUP) available in the SS7 network. There is no need, then, to upgrade network switches to introduce IN; the existing protocols will suffice. Moreover, by using “loop routes” it is possible for a single Open SN platform to serve many network switches. This reduces the implementation cost, both in terms of service node hardware and in transmission costs. Loop routes are also utilised by the Signalling Interface Processor , where they are explained more fully. Reliable performance All the functions of the Open SN are duplicated for reliability as in other OT IN products. The Open SN has been designed for a moderate call load of 40 calls/s, which can be increased by installing multiple service node sites. For significantly higher loads, we expect that use of the Open SCP will be more efficient. With a full range of OAM features As with all OT products, the Open SCP is built for real telecom environments, with a full set of operation, administration and management features, including: online loading of new services and new service versions online management and backup of data, including voice prompts all OAM functions accessible via a text command / response interface or via CORBA objects extensive statistics comprehensive alarm indications diagnostic trace functions for call events For further information on the Open SN or any other OT products please contact us at [solutions@ot.com.au].
