Paradyne 7112 Displaying DS0 Channel Assignments, Using the Block or Acami Assignment Method

Configuring the DSU/CSU

Displaying DS0 Channel Assignments

Use the Cross Connect Assignments screen to view which DS0 channels are currently assigned to the data port. Below each DS0 channel you will see either ªAvailableº or ªPº. DS0s with a ªPº designation are assigned to the data port. DS0s marked ªAvailableº are unused (unassigned).

Cross Connect Assignments may also be displayed by accessing the Cross

Connect Status screen under the Status branch of the Main Menu.

Using the Block or ACAMI Assignment Method

By using the block or ACAMI (Alternate Channel Alternate Mark Inversion) assignment method, you can assign a data port to a block of contiguous DS0 channels on the network interface.

The block assignment method allows a block of contiguous channels to be assigned by specifying the number of DS0's to allocate and an initial DS0 channel (the first DS0 channel in a block of DS0 channels). The number of channels assigned is determined by the port rate. These channels are automatically assigned to the destination network interface when the initial DS0 channel is selected.

The ACAMI assignment method also allows a block of contiguous channels to be assigned. However, with ACAMI, the number of channels assigned is twice the number needed for the port rate. This is because with ACAMI, every alternate DS0 channel (starting with the n+1 DS0 channel), does not carry data from the port, but instead always transmits and receives all ones.

"Procedure

To assign data ports by the block or ACAMI method:

1.Access the Cross Connect Assignments screen by following this menu selection sequence:

Main Menu → Configuration → Load Configuration From →

Cross Connect

2.Use the Assign By field to specify the assignment method (Block or ACAMI).

3.After filling in the DS0s to Allocate field, specify a port assignment for the first DS0 channel in a block of contiguous, available DS0 channels.

4.Select Ctrl-a and then Save to save your changes.
