Sync Data Port Assignments

Assign To: Network

Network DTE Port

Allows you to assign a synchronous data port to DS0 channels on either the network interface, the DTE Drop/Insert (DSX-1) interface, or another port.

Network – Assigns this port to DS0 channels on the network interface.

DTE – Assigns this port to DS0 channels on the DTE Drop/Insert (DSX-1) interface. If the DTE Drop/Insert (DSX-1) interface is disabled, this selection does not appear.

Port – Assigns this port to another port. Use this feature to designate a port as a backup port. You can attach an external backup device to a backup port 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. 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 T1 interface to the other (Network or DTE) deallocates all DS0 channels assigned to the previous interface.

Sync Data Port Assignments

Assign By: Block

Block ACAMI Channel

If you select NET or DTE using the Assign To configuration option, this configuration option 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 Alternate Mark Inversion 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.

Channel – Allocates DS0 channels to this port by the individual channel method.

NOTE: Changing this configuration option from one method to another (Block, ACAMI, or Channel) deallocates all DS0 channels assigned to either the network interface or the DTE Drop/Insert (DSX-1) interface.
