ACCULINK 316x DSU/CSU
Prt(1, 2, 3, or 4):
Data Port Channel. Assigns the port to DS0 channels on either the Network T1 interface or the DSX-1 Drop/Insert T1
interface. When you select a port, some of the following configuration options appear, depending on your selections.
NOTE: Ports 3 and 4 are not available on Model 3161 DSU/CSUs.
Assign To: NET
Next NET DTE Prev
Data Port Channel Allocation Destination. Assigns this port to either the Network or DSX-1 Drop/Insert T1 interface.
NET – Assigns this port to DS0 channels on the Network T1 interface.
DTE – Assigns this port to DS0 channels on the DSX-1 Drop/Insert T1 interface.
NOTE: When you change this configuration option from one T1 interface to the other, the DSU/CSU deallocates all DS0
channels allocated to the previous interface.
NOTE: The DTE selection will not be displayed if the DSX-1 Drop/Insert T1 interface is disabled.
Assign By: Block
Next Block ACAMI
Data Port Channel Allocation Method. Designates the method for assigning DS0 channels to the destination T1 interface.
Block – Allocates DS0 channels to this port by the block method.
ACAMI – Allocates DS0 channels to this port by the Alternate Channel AMI method. The difference between block and
ACAMI is that the number of channels allocated with ACAMI is double the number needed for the port rate. With ACAMI,
every alternate DS0 channel does not carry data from the port but always transmits and receives all ones.
Chan – Allocates DS0 channels to this port by the individual channel method.
NOTE: When you change this configuration option from one method to another, the DSU/CSU deallocates all DS0
channels allocated with the previous method.

Data Port Rate (appears for the block and ACAMI methods only). Designates the data rate for the port. Available
selections depend on the current base rate configured for the port. The factory default for Nx64 is
384 kbps and Nx56 is 336 kbps.
NOTE: When you change this configuration option from one rate to another, the DSU/CSU deallocates all DS0 channels
allocated based on the previous rate.
NOTE: This configuration option does not appear if the individual channel allocation method (Chan) is selected using
the Assign By configuration option.
