The tables defined by this MIB module contain a collection of managed objects that are general in nature and apply to different types of modems. The structure of this module resembles the ADSL-LINE-MIB, CISCO-SDSL-LINE-MIB, ADSL-DMT-LINE-MIB, CISCO-ADSL-DMT-LINE-MIB, etc. Observe that the tables in this module do not necessarily extend the tables defined by the these mibs. Currently, only the table that contains the configuration information extends the profile tables defined by the above modules. Mib objects must fulfill the following criteria to be contained in this mib module: 1) The ADSL-LINE-MIB or the modem specific mibs such as CISCO-SDSL-LINE-MIB, CISCO-ADSL-DMT-LINE-MIB, etc. does not already contain a managed object representing the same information. 2) The mibs object must NOT be technology dependent, they must apply to various types of DSL modems, e.g. IDSL, SDSL, ADSL, etc. *** ABBREVIATIONS, ACRONYMS, AND SYMBOLS *** ADSL - Asymmetric Digital Subscriber Line. ATM - Asynchronous Transfer Mode. XTU-C - xDSL Transceiver Unit, Central Office end. XTU-R - xDSL Transceiver Unit, Remote terminal end. BER - Bit Error Ratio. BERT - Bit Error Ratio Test. DSP - Digital Signal Processor. DSL - Digital Subscriber Line. IDSL - IDSN Digital Subscriber Line. SDSL - Symetric Digital Subscriber Line. xDSL - Group term used to refer to ADSL, HDSL, SDSL, VDSL, IDSL, etc. All are digital technologies using existing copper lines provided by the thelephone companies.
