Selecting a CS PDU Encapsulation Method

You can use one of three CS PDU encapsulation methods at the ATM DXI

interface level -- AAL 5 Encapsulation, AAL 3/4 Encapsulation, and No

Encapsulation.

Deﬁning the CS PDU encapsulation on the interface level sets the default value

for any PVCs you may add. Normally, any new PVCs use the default AAL 5

encapsulation. By setting the CS PDU encapsulation method to AAL 3/4 at the

interface level, all new PVCs that you add to the interface automatically use

AAL 3/4 encapsulation.

Use No Encapsulation (a proprietary value) if you do not want the interface to use

any CS PDU encapsulation.

When selecting a CS PDU encapsulation, choose the encapsulation method that

you want most PVCs on the interface to use. You can always change the

encapsulation method for individual PVCs after you add them.

Enabling or Disabling the Multicast Function

By default, the ATM DXI interface does not accept multicast packets. However,

you can enable the multicast function to accept multicast packets.

Caution: When assigning data encapsulation to an interface, make sure that

the encapsulation method matches that of the receiving device on the other end

of the ATM network.
