The STEM newsletter is a quarterly bulletin designed to keep you informed of the latest developments in STEM: interesting applications, the latest features and a series of how-does-it-work articles, together with news of forthcoming events.
A concise summary of the demand and supply sides of incremental demand, maximum utilisation, deployment, planned units, supply ratios, Functions and pre-run installation.
The Seventh Annual STEM User Group Meeting will be held on 18–20 September 2002 in the traditional surroundings of Emmanuel College, Cambridge, UK, and is of interest and value to current and prospective users alike. This popular event delivers insight into best modelling practice and deeper understanding of the latest developments in STEM, and also provides a great opportunity to meet and learn from other STEM users.
A new suite of STEM reference models on ADSL, MAN, UMTS and WLAN, published on this site in February 2002, have been attracting a lot of attention. With the imminent release of STEM 6.2, we are now looking at how this new technology revolutionises and simplifies conventional approaches to modelling service packages and cost categories.
The long-awaited 6.2 update to the STEM modelling platform is nearing completion, with time-series views in the Editor, persistent formatting of graphs and tables in the Results Program and a powerful new template-replication feature with the potential to massively streamline the service and cost structures of large models.
An examination of the cost-allocation mechanism in STEM, looking at the calculation structure, multiple cost streams, resource age tracking and used/slack costs, plus a preview of some new developments including direct costs, intermediate slack results and breakdown of service costs by resource.
In order to determine a pricing strategy for long-term survival, carriers can use STEM to automatically calculate the unit costs of all services provided on a telecoms network, broken down at the modeller’s discretion into access costs per line, backbone network costs per Mbyte or simply total costs per minute.
Telkom Indonesia wished to model a voice backbone network with 29 trunk switches from three different manufacturers and 178 bearers on a number of transmission technologies. Building such a complex model would normally be a time-consuming process, but STEM’s new replication feature enabled Telkom to quickly determine the LRIC of a minute of traffic on each of a total of 435 routes between trunk switches.
A familiar interface is a must-have for peripheral STEM users, from colleague to customer, and here we provide an essential guide to the ins and outs of linking STEM model inputs to data in Excel.
The STEM User Group Meeting in Cambridge in September saw the first live demonstration of the new eSTEM technology, a COM interface enabling D-STEM licensees to publish access to STEM models in a Web browser.
Analysys is providing the network modelling software and telecom scenarios for an interactive online game, produced by Light Reading, which will let you play the role of an ILEC looking to upgrade its existing network infrastructure. You'll set tariffs, select various next-generation network technologies, and then compare RoI with other competitors.
