• Receive Size (for AAL5 connections only)
• Encaps Type (for AAL5 connections only)
Encaps Type
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. (Reference RFC 1483 
Multiprotocol Encapsulation over ATM AAL5 and 
the ATM Forum LAN Emulation specification.)
AAL (ATM Adaptation Layer) Type
Only exists when the local VCL endpoint is also 
the VCC endpoint, and AAL is in use. The field 
indicates the type of AAL used on this VCC, which 
includes AAL1, AAL3/4, and AAL5. The value 
“Other”
 is a user-defined AAL type. “Unknown” 
indicates that the AAL type cannot be determined.
Last Change
The value of “sysUpTime” at the time this VCL 
entered its current operational state. If the 
current state was entered prior to the last re-
initialization of the agent, then this field contains 
a zero value.
Cross Connect Id
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.
Xmit Descr Index
Identifies the row of the ATM Traffic Descriptor 
Table that applies to the transmit direction of this 
VCL.
Transmit Size
Only exists when the local VCL endpoint is also 
the VCC endpoint, and AAL5 is in use. The 
maximum AAL5 CPCS SDU size in octets that is 
supported on the transmit direction of this VCC.
Rcv Descr Index
Identifies the row in the ATM Traffic Descriptor 
Table that applies to the receive direction of this 
VCL.
Receive Size
Only exists when the local VCL endpoint is also 
the VCC endpoint, and AAL5 is in use. The 
maximum AAL5 CPCS SDU size in octets that is 
supported on the receive direction of this VCC.
