Configuration OptionsC-73360-A2-GB20-20 December 1996Network InterfaceConfiguration OptionsTable C-3Network Interface Configuration OptionsHDSL Mode: NTUNext NTU LTU PrevHDSL Mode. Specifies whether the operating mode is Network Termination Unit (NTU) or Line Termination Unit (LTU). Ina poll/response environment, the LTU serves as the control unit that polls the NTU and controls such items as thedistribution of payload data, start-up procedures, and timing references.NTU – Configures for the NTU mode.LTU – Configures for the LTU mode.NET Frame: noCRCNext CRC4 noCRC PrevNetwork Line Framing Format. Designates the framing format for the HDSL Network interface.CRC4 – Configures for the CRC4 framing format.noCRC – Configures for the non-CRC4 framing format.Mgmt Link: DisabNext Disab SNMP PrevFDL Management Link. Specifies whether Facility Data Link (FDL) is enabled. Selecting SNMP allows SNMPmanagement traffic to flow over the 4 kbps data link provided by FDL. Running SNMP over FDL requires an end-to-endFDL connection and cannot be terminated within the network.Disab – Disables the FDL Management Link.SNMP – Enables the FDL Management Link for SNMP.NOTE: This configuration option is not available if EDL is enabled for SNMP.NOTE: If the local E1 NTU’s FDL is enabled for SNMP, the remote E1 NTU’s FDL must also be enabled for SNMP.HDSL: DisabNext Disab Maint PrevHDSL Performance Statistics. Specifies whether to monitor local HDSL performance statistics for each loop and maintainLoop 1 (Lp1) and Loop 2 (Lp2) performance registers.Disab – Disables Lp1 and Lp2 performance statistics.Maint – Maintains Lp1 and Lp2 performance statistics.Circuit Ident:Next Edit Clear PrevNetwork Circuit Identifier. Specifies the transmission vendor’s circuit identifier for the purpose of facilitatingtroubleshooting. The network circuit identifier is an ASCII text string that may be up to 255 characters in length.Edit – Allows you to edit and/or display the network circuit identifier using the generic text string entry screen.Clear – Allows you to clear the network circuit identifier. The network circuit identifier will be set to a null string.
