Data Port Channel Configuration Options
Channel Config:
Dsply Clear DTE Prt1 Prt2 Prt3 Prt4
_______________________
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,

.
Data Port Channel. Allows the assignment of a particular port to DS0 channels on either the network interface, the G.703
DTE interface, or another port (see the Assign To configuration option below).
NOTE: For 2-port E1 NTUs, only Ports 1 and 2 are available; for 1-port E1 NTUs, only Port 1 is available.

Data Port Channel Allocation Destination. Allows you to assign this port to DS0 channels on either the network interface,
the G.703 DTE interface, or another port.
NET – Assigns this port to DS0 channels on the network interface.
DTE – Assigns this port to DS0 channels on the G.703 DTE interface. If the G.703 DTE 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
4-port E1 NTUs. 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. EDL (for 2-port and 4-port E1 NTUs) 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 interface or the G.703 DTE interface.
