Allocating Data Ports Using the Block or ACAMI Assignment Method
By using the block or ACAMI (Alternate Channel Alternate Block Inversion)
assignment method, you can assign a data port to a block of contiguous DS0
channels on either the network interface or the DTE Drop/Insert (DSX-1)
interface.
The block assignment method allows a block of contiguous channels to be
assigned by specifying a data port rate 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 T1 interface (Network or DTE Drop/Insert) 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. From the Main Menu screen, select Configuration.
2. From the Load Configuration From screen, select Current.
3. From the Configuration Edit/Display screen, select Cross Connect.
4. From the Cross Connect screen, select Sync Data Port Assignments.
5. Use the Assign To field to specify the destination T1 interface (Network or
DTE).
6. Use the Assign By field to specify the assignment method (Block or ACAMI).
7. After filling in the Port Rate field, specify a port assignment for the initial DS0
channel in a block of contiguous, available DS0 channels.
8. Select S
ave or, if you want to return to the Cross Connect screen, press your
Esc key and then save your changes from that screen.
