Product Category Definitions Category Code Category: Definition: Examples: Wireless Transmission Equipment for analog or digital transmission to the subscriber unique to wireless services. This category does not include interoffice or longhaul wireless carrier systems. Base Station Equipment Equipment which provides the interface between wireless systems and the Public Switched Telephone Network (PSTN). It provides, for example, electrical signaling isolation as well as switching, routing, billing, and features capabilities. It provides subsystems for vocoding and selecting hand off decision. ? BSC ? BSS Base Transceiver System (BTS) Equipment which provides the radio link to the mobile subscribers. It is connected to the BSC though a backhaul interface between the BSC and BTS for both vocoded and overhead packet traffic. ? BTS Pilot Beacon Unit (PBU) Equipment whose primary purpose is to transmit and ANSI JSTD008 Pilot channel and ANSI J STD008 Sync channel and a partial ANSI JSTD008 Paging channel. The PBU is intended to notify a mobil unit of a change in CDMA coverage and can be used to assist in the execution of cellular CDMAAMPS and interfrequency CDMACDMA handoff. It is designed with the capability for extended temperature and environmental operation ranges. 4 Operations amp。 OTD) are applicable and required for all product categories.

Product Category Definitions Category Code Category: Definition: Examples: NOT generally in series with the customer circuit and may be connected to a variety of access equipment and work elements with integral access features. This equipment may have analog and perhaps a variety of digital (., T1, E1) types. Failure of this equipment doesn39。 however, it inhibits the ability to maintain the work and to restore lost service. Test Support Software Computer software that runs on a general purpose puter (office environment) and perhaps the maintenance work that the puter uses to municate with the CO access and test equipment. Operations Support Systems Systems that provide TMN (Telemunication Management Network) pliant, flexible, scaleable, and interoperable solutions to automate service activation, service assurance, and work capacity management processes to worldwide existing and emerging work services and equipment providers. On Line Critical Real time systems, demanding high availability, typically 24 hours a day and 7 days per week. ? Network traffic management ? Surveillance of 911 ? Fire alarms On Line Noncritical Real time systems with lower availability demands than on line critical systems. ? Provisioning ? Dispatch ? Maintenance Off Line Traditional business systems that are run off line sometimes in batch mode, typically overnight and do not have high availability expectations. ? Inventory ? Billing records ? Service creation platform 5 Common systems Any of a variety of specialized generic, shared equipment to support work elements. Common systems include power systems and the Network EquipmentBuilding System (NEBS) that provides space and environmental support for work elements. These systems are located in central offices and remote building locations. 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.

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.
