The AAL2 Virtual Channel Link (VCL) Table
          
This table contains configuration and state 
information of a bi-directional AAL2 Virtual 
Channel Link (VCL) at an ATM interface. Each 
VCL entry has an associated Connection 
Identifier (CID) table, comprised of one or
more CID entries.  Each VCL entry refers to
an Audio Profile (AP) by type (pre-defined or 
user-defined) and index into an AP table.
          
An AAL2 VCL entry is created by the agent 
when an RFC2515 (ATM-MIB) atmVclEntry of 
atmVccAalType 2 is created.  Objects in the 
row entry can by modified by CLI or ZMS if 
the connection is down.  Deletion of AAL2 VCL 
entries is controlled by the rfc2515 (ATM-MIB) 
atmVclRowStatus.

The AAL2 Channel Identifier (CID) Table
          
The AAL2 Channel Identifier Table contains 
status, I.366.2 SSCS parameters, and I.366.1 
SSCS parameters for the channel identifier. 
Default values for these objects are defined
in the AAL2 VCL entry.  Values in the AAL2 
Channel Identifier entry can supercede the 
defaults specified in the AAL2 VCL entry.
          
The maximum number of connections or CIDs
allowed per ATM VCL is 255.
          
Certain atmVccAal2AppID values (ie, any app
running over Common Channel Signaling) can 
cause the auto-creation of an AAL2 CID entry.
When the creation of an AAL2 VCL entry does 
not lead to the auto-creation of an AAL2 CID 
entry by the agent, a CLI or ZMS request from 
the CLI or ZMS can use the AAL2 CID entry 
RowStatus object, aal2CidRowStatus, to create 
an aal2CidEntry instance.  In this case, an 
rfc2515 (ATM-MIB) atmVclEntry must exist prior 
to creating an AAL2 CID entry.
          
AAL2 CID entry deletion is accomplished with 
the AAL2 CID entry RowStatus object, 
aal2CidRowStatus.  If an AAL2 VCL entry
is deleted, then the agent cleans up all
associated AAL2 CID entries.

AAL2 Audio Profile Table
          
A profile is a set of entries, where each 
entry specifies an encoding format (see 
STR-VMOA-LES-01-00 Annex A) with a UUI range
and length. This set defines a mapping that 
informs the receiver of a type 1 packet how 
to interpret the packet contents, i.e. which 
encoding format in the profile is being used. 
Once a profile is adopted between a transmitter 
and a receiver, the transmitter can select 
any entry of the adopted profile and the 
receiver shall accept any entry selected by 
the transmitter.
          
Unlike the Pre-defined Audio Profile entries, 
which are created by the agent, the User-defined 
Audio Profile entries consists of READ-CREATE 
objects created via CLI or ZMS.
