Channel Config:
Dsply Clear DTE Prt1
_______________________
NOTE: The configuration options described in this table are made available by selecting Prt1, Prt2, Prt3, or Prt4
from this Channel Config screen. Table C-4 describes the DTE configuration options. For information
about the operation of Display and Clear, refer to the Configuring DS0 Channels section in Chapter 3,
Operation .
Data Port Channel. Allows the assignment of a particular port to DS0 channels on either the Network E1 interface, the
DTE Drop/Insert interface, or another port (see the Assign To configuration option below).
NOTE: For Model 3172 DSU/CSUs, only Ports 1 and 2 are available.
Assign To: NET
Next NET DTE Prt n
Data Port Channel Allocation Destination. Allows you to assign this port to DS0 channels on either the Network E1
interface, the DTE Drop/Insert interface, or another port.
NET – Assigns this port to DS0 channels on the Network E1 interface.
DTE – Assigns this port to DS0 channels on the DTE Drop/Insert interface. If the DTE Drop/Insert interface is disabled,
this selection is not displayed.
Prt n – Assigns this port to another port, where n is the port number of all available ports except the port selected from the
Channel Config screen. For example, if you select Prt1 from the Channel Config screen, Prt2, Prt3, and Prt4 appear for
the 3174. Use this feature to designate a port as a backup port. You can attach an external backup device to Prt n and
manually assign the selected port to the backup port (i.e., route data from the selected port to the backup port). When a
port is assigned to another port, DSR is turned on. Selecting Prt n and Next takes you directly to the Port Rate
configuration option, bypassing the Assign By configuration option. Only data ports with matching port base rates (i.e.,
Nx56 or Nx64) are displayed. Also, EDL does not operate 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 E1 interface to the other (NET or DTE) deallocates all DS0 channels
allocated to the previous interface.
Assign By: Block
Next Block Chan Prev
Data Port Channel Allocation Method. If NET or DTE is selected using the Assign To configuration option, this
configuration option designates the method for assigning DS0 channels to the destination E1 interface.
Block – Allocates DS0 channels to this port by the block method.
Chan – Allocates DS0 channels to this port by the individual channel method.
NOTE: If time-slot 16 is reserved for signaling, the DS0 channels associated with time-slot 16 are not available for
assignment using either method (Block or Chan).
NOTE: Changing this configuration option from one method to the other (Block or Chan) deallocates all DS0 channels
assigned to either the Network E1 interface or the DTE Drop/Insert interface.
