L2 PROTOCOL (ATM–NET–ATM) > CONFIG > ATM CONFIG > DATA SCRAMBLING

DATA SCRAMBLING can be ENABLED or DISABLED for cell traffic. Configuring this setting incorrectly for a particular circuit will cause poor performance at the ATM Layer.

The setting must match the configuration setting of the ATM switch or DSLAM at the other end of the circuit.

L2 PROTOCOL (ATM–NET–ATM) > CONFIG > ATM CONFIG > HEC COSET

Header Error Control is located in the last (5th) byte of the ATM cell header that checks for cell integrity only. The Coset polynomial is applied to the received HEC for comparison with the HEC generated internally. HEC errors may be detected after synchronization, and any detected bit errors prompt that the cell be dropped. The choice are ENABLED (def) or DISABLED.

L2 PROTOCOL (ATM–NET–ATM) > CONFIG > PVC CONFIG

Configure up to six ATM PVCs from this menu (five data and one voice PVC).

To insert a new PVC, press the I key when over the NUM column. A new inserted PVC will always be set up with the default parameters. To copy parameters from an old PVC to the new PVC, use the copy (C) and paste (P) keys. Entire configuration trees can be copied with this method.

To delete an unused PVC, use the D key when the cursor is over the number in the NUM column. Once deleted, the PVC is gone permanently.

L2 PROTOCOL (ATM–NET–ATM) > CONFIG > PVC CONFIG > NUM

Displays the index number for the PVC entry.

L2 PROTOCOL (ATM–NET–ATM) > CONFIG > PVC CONFIG > ACTIVE

Activates the ATM PVC. The choices are YES or NO. Default is NO.

L2 PROTOCOL (ATM–NET–ATM) > CONFIG > PVC CONFIG > SUB-INTERFACE

This is a read-only field which displays the physical and logical port of the interface using the following nomenclature: [A.B], where A represents the physical port (network interface is 0, Ethernet is 1) and B represents the logical port for the Layer 2 protocol (i.e. PVC for Frame Relay, PPP link, etc.) Each configured logical port is assigned a number corresponding to the order in which they are listed in the L2 Protocol configuration fields.

L2 PROTOCOL (ATM–NET–ATM) > CONFIG > PVC CONFIG > VPI

ATM Virtual Path Identifier located in the ATM cell header identifies the virtual path over which this port is running. The range is 0-256. The default is 0.
