Although monly installed on the subscriber’s premises, equipment with essentially identical function installed in the service provider’s facility may also be classified as customer premises equipment. Enhanced Services Platforms Systems that provide an environment in which servicespecific application programs can execute and an infrastructure by which those application programs can provide enhanced services. Although each enhanced services platform has a corresponding service creation environment, that creation environment is sometimes packaged separately and may execute on a different platform. Interactive Voice Response (IVR) Platforms Equipment used to allow menu navigation and information retrieval, often from legacy databases external to the IVR platform itself. Messaging Platforms Equipment for storage and retrieval of voice and/or fax messages Voice mail systems MultiApplication Platforms Equipment which provides an environment rich in capabilities so that multiple, possible disparate services can be provided concurrently. Unified/Universal Messaging (system providing a subscriber the means, from a given device, to manipulate messages originated on like or different devices. Such devices include, but are not limited to, conventional telephone handsets, wireless handsets, PC terminals, 企業(yè) () (大量管理資料下載 ) Note 1:Product Categories listed in RED and italicized will be used for possible Data Aggregation only.

Dense Wavelength Division Mulitplexer Microwave Carrier system that employs fixed microwave transmission. ? 6, 8, 11, or 18 gigahertz microwave radio Loop Carrier Equipment for deploying multiple voice or digital channels over fewer physical channels than would be otherwise required (a “pair gain” function). ). Loop carriers are typically digital systems which employ timedomain multiplexing (TDM) but may include analog systems as well. Loop carrier systems consist of a Central Office Terminal (COT) located near the switching system, a Remote Terminal (RT) located near the customer to be served and a transmission facility connecting the COT to the RT. Individual munications circuits (such as POTS and Foreign Exchange [FX]) are accepted as separate inputs at the COT (RT), timedivision multiplexed (in a digital loop carrier) by the loop carrier system and reproduced at the RT (COT). ?

Product Category Definitions Category Code Category: Definition: Examples: (TCAP) queries and responses are used to municate with the SCP as is done for 800 Data Base Service and ABS. SCPs may support one (1) or more services per SCP and SCPs may be deployed singularly as standalone nodes, as mated pairs, or as multiple replicates (more than 2) to increase their availability. SCPs, connected to STPs, are associated with applications that consist of servicespecific software and a database of customerrelated information. This product category includes conventional SCP equipment, plus other platforms such as service nodes, intelligent peripherals, or service resource facilities, which may bine capabilities of a SCP, SSP or which may be used to provide AIN functionality or other enhanced services within the work. ?
