9A426-01/9A426-02 Module Specific Information

Add/Delete Entry Screen Fields

The following information briefly explains each Add/Delete Entry Screen field.

VPI

Displays the Virtual Path Identifier number of the connection you want to add or delete.

VCI

Displays the Virtual Channel Identifier number of the connection you want to add or delete.

AAL Type (Toggle)

Displays the types of ATM adaptation layer used on this VCC. Use the Space Bar to select one of the following choices:

•AAL3/4

•AAL5 (default)

Encapsulation Type (Toggle)

Displays the methods used to encapsulate data at the ATM Adaptation Layer 5 (AAL5) for each connection. The 9A426-01/9A426-02 modules support the following methods of encapsulation:

•VC Mux 802.3 LANE (default)

VC Based Multiplexed 802.3 LAN Emulation. This is the encapsulation type used when the connection is set up via SVCs. These happen automatically in the network with no user intervention.

•VC Mux Bridged 802.3

VC Based Multiplexing for bridged protocols. You can choose this encapsulation type for PVCs to do bridging.

•LLC Encapsulation

Logical Link Control for Bridged Protocols. You can choose this encapsulation type for PVCs. You cannot use this encapsulation type for SVCs.

LLC Encapsulation inserts an LLC SNAP header for each legacy LAN network type that is being encapsulated onto ATM. LLC Encapsulation is desirable when it is not feasible for a larger number of VCs to be supported, due to ATM device capacity limitations or other outside factors.

•Other

This encapsulation type is for reserved connections that are defaults built into most (if not all) ATM LANE 1.0 compliant devices. In other words, they are neither configured by hand nor set up dynamically.
