operational state. If the current state was entered
prior to the last re-initialization of the agent, then
this object contains a zero value.
RTD (Receive Traffic Description) Index
The value of this object identifies the row in the
ATM Traffic Descriptor Table that applies to the
receive direction of this VCL.
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.
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
Row Status agent after the associated entries in
the Cross Connect Table have been created.
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
