TTD (Transmit Traffic Description) Index
The value of this object identifies the row of the ATM Traffic Descriptor Table
that applies to the transmit direction of this VCL.
AAL (ATM Adaptation Layer) Type
An instance of this object only exists when the local VCL endpoint is also the
VCC endpoint and the AAL is in use. The type of AAL used on this VCC
includes AAL1, AAL3/4, and AAL5. “Other” indicates a user-defined AAL type.
“Unknown” indicates that the AAL type cannot be determined.
Transmit Size
This is the maximum AAL5 CPCS SDU size, in octets, that is supported on the
transmit direction of this VCC. An instance of this object only exists when the
local VCL endpoint is also the VCC endpoint and the AAL5 is in use.
Receive Size
This is the maximum AAL5 CPCS SDU size, in octets, that is supported on the
receive direction of this VCC. An instance of this object only exists when the
local VCL endpoint is also the VCC endpoint and the AAL5 is in use.
Encaps Type
This is the type of data encapsulation used over the AAL5 SSCS layer. An
instance of this object only exists when the local VCL endpoint is also the VCC
endpoint and the AAL5 is in use. The definitions reference RFC 1483
Multiprotocol Encapsulation over ATM AAL5 and to the ATM Forum LAN
Emulation specification.
VCL CC (Cross Connect) Id
This object is implemented only for a VCL that is cross-connected to other
VCLs that belong to the same VCC. All such associated VCLs have the same
value for this object, and all their cross-connections are identified by entries in
the Cross Connect Table for which VCL CC Id has the same value. The value
of this object is initialized by the agent after the associated entries in the
Cross Connect Table have been created.
Row Status
This object is used to create, delete, or modify a row in this table. To create a
new VCL, this object is initially set to “createAndWait” or “createAndGo.” This
object must not be set to “active” unless the following columnar objects exist in
this row:
• RTD Index
• XTD Index
• AAL Type (if the local VCL endpoint is also the VCC endpoint)
• Transmit Size (for AAL5 connections only)
• Receive Size (for AAL5 connections only)
• Encaps Type (for AAL5 connections only)
