Xmit Desc. Index The value of this field identifies the row of the ATM Traffic
Descriptor Table that applies to the transmit traffic direction of this
VCL.
AAL Type An instance of this field only exists when the local VCL endpoint is
also the VCC endpoint, and AAL (ATM Adaptation Layer) is in use.
The field indicates the type of AAL used on this VCC, which
includes AAL1, AAL3/4, and AAL5. The “other” type is a user-
defined AAL type. The “unknown” type indicates that the AAL type
cannot be determined.
Transmit Size An instance of this field only exists when the local VCL endpoint is
also the VCC endpoint, and AAL5 is in use. The field indicates the
maximum AAL5 CPCS SDU size, in octets, that is supported on the
transmit direction of this VCC.
Receive Size An instance of this field only exists when the local VCL endpoint is
also the VCC endpoint, and AAL5 is in use. The field indicates the
maximum AAL5 CPCS SDU size, in octets, that is supported on the
receive direction of this VCC.
Encaps Type An instance of this field only exists when the local VCL endpoint is
also the VCC endpoint, and AAL5 is in use. The field indicates the
type of data encapsulation used over the AAL5 SSCS layer. The
definitions reference RFC 1483 Multiprotocol Encapsulation over
ATM AAL5 and ATM Forum LAN Emulation specification.
Cross Connect Id This field 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 of this field, 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 field is initialized by the
agent after the associated entries in the Cross Connect Table have
been created.
