Note 2:Remember that the following Metrics (FRT, OFR amp。 OTD) are applicable and required for all product categories. TL 9000 質量管理體系測量手册 A8 Table A1. Product Category Definitions Category Code Category: Definition: Examples:  Pedestals  Microwave / radio towers Conduits Channels for the containment of optical fiber or metallic cable.  Innerduct  Multibore conduit  PVC pipe Transport Equipment Equipment located in the central office or at the customer premises, but inside the work demarcation point, for the transmission of digital or analog munication over transmission media. This product category includes equipment for terminating, interconnecting, and multiplexing munications circuits. Cross Connect Systems Equipment to provide a physical termination point for physical cables and individual conductors. They can be manual or automated, metallic or optical. Crossconnect systems, such as distributing frames, Digital Signal Cross Connects (DSXs) and Fiber Distributing Frames (FDFs) provide the following basic functions: crossconnection of work distribution facilities and equipment in the central office, electrical protection for conductive media, test access, temporary disconnection, and termination points for facilities and equipment.  Digital Signal Cross Connect (DSX)  Digital Interface System (DIS)  Fiber Distribution Frame (FDF)  Feeder Distribution Interface (FDI)  Digital Crossconnect System (DCS)  Electronic DSX  Optical DSX  Optical Interface Systems Carrier Systems / Multiplexers Equipment for transmitting multiple munication channels over a single transmission facility. This category includes equipment for transmission over interoffice trunks, for example, from central to remote offices. Interoffice / Long Equipment for transmission between central offices, between 企业 () (大量管理资料下载 ) Note 1:Product Categories listed in RED and italicized will be used for possible Data Aggregation only.

TL 9000 質量管理體系測量手册 A9 Table A1. Product Category Definitions Category Code Category: Definition: Examples: Haul exchanges, or between carriers, as opposed to transmission between an end office and a remote location, typical of a loop carrier. Metallic Carrier System Carrier system that uses metallic transmission medium.  Analog carrier (N,L carrier)  D4, D5 digital carrier Optical Carrier System Carrier system that uses optical transmission medium. SONET / SDH Transport Systems Fully featured digital transmission system employing optical medium  OC3, 12, 48, or 192 SONET equipment configurable as linear or ring.  Similar for STMx SDH equipment WDM / DWDM / Optical Amplification Products Shelf level subsystems used for multiplexing, demultiplexing, or amplification of optical signals. Lack the built in protection, electrical conversion and other features of a SONET Transport System.  Wavelength Division Multiplexer [WDM]  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).  Digital loop carrier (DLC)  Universal digital loop carrier (UDLC)  SLC remote terminal  Integrated digital loop carrier  Analog loop carrier 企业 () (大量管理资料下载 ) Note 1:Product Categories listed in RED and italicized will be used for possible Data Aggregation only.

TL 9000 質量管理體系測量手册 A10 Table A1. Product Category Definitions Category Code Category: Definition: Examples: There is an analogtodigital (A/D) conversion of analog inputs to the DLC and these signals, which are carried digitally within the DLC, undergo a digitaltoanalog (D / A) conversion when output at the COT or RT. The transmission facility used by a loop carrier may be metallic cable pairs, repeated metallic cable pairs, or optical fibers. Line Terminating Equipment / Distributing Frames Equipment to provide the termination point for voicegrade and voicegrade patible facilities and equipment in a central office. It is posed of protectors, connectors and terminal strips or blocks. Distributing frames are categorized as either conventional or modular.  Tall conventional distributing frames  LowProfile Conventional Distribution Frames (LPCDFs)  Conventional protector frames  Combined Main Distributing Frame (CMDF)  Subscriber Main Distributing Frame (SMDF)  Trunk Main Distributing Frame (TMDF)  Inter。
