Configuration OptionsC-12 3162-A2-GB20-40August 2000Sync Data Port Assignment OptionsTable C-5. Sync Data Port Assignment Options (1 of 3)Sync Data Port AssignmentsAssign To: NetworkNetwork DTE PortAllows you to assign a synchronous data port to DS0 channels on either the networkinterface, the DTE Drop/Insert (DSX-1) interface, or another port.Network – Assigns this port to DS0 channels on the network interface.DTE – Assigns this port to DS0 channels on the DTE Drop/Insert (DSX-1) interface. Ifthe DTE Drop/Insert (DSX-1) interface is disabled, this selection does not appear.Port – Assigns this port to another port. Use this feature to designate a port as abackup port. You can attach an external backup device to a backup port and manuallyassign the selected port to the backup port (i.e., route data from the selected port to thebackup port). When a port is assigned to another port, DSR is turned on. EDL does notoperate when a synchronous data port is assigned to another synchronous data port.Therefore, if EDL is enabled, it is ignored.NOTE: Changing this configuration option from one T1 interface to the other(Network or DTE) deallocates all DS0 channels assigned to the previousinterface.Sync Data Port AssignmentsAssign By: BlockBlock ACAMI ChannelIf you select NET or DTE using the Assign To configuration option, this configurationoption designates the method for assigning DS0 channels to the destination T1interface.Block – Allocates DS0 channels to this port by the block method.ACAMI – Allocates DS0 channels to this port by the Alternate Channel Alternate MarkInversion method. The difference between block and ACAMI is that the number ofchannels allocated with ACAMI is double the number needed for the port rate. WithACAMI, every alternate DS0 channel does not carry data from the port but alwaystransmits and receives all ones.Channel – Allocates DS0 channels to this port by the individual channel method.NOTE: Changing this configuration option from one method to another (Block,ACAMI, or Channel) deallocates all DS0 channels assigned to either thenetwork interface or the DTE Drop/Insert (DSX-1) interface.
