The Configuration field allows each connection to be independently provisioned:

-
Bit
Name
Definition
5
CONTYP
The connection type. If this bit is 1, the VC is an ABR
connection. Otherwise, the VC is a VBR/CBR
connection. This bit affects the choice of Cell Rate
Policing Configuration Registers. When CONTYP is 1
(an ABR connection), the ABR Cell Rate Policing
Configuration registers are used by the policing
processor, when CONTYP is 0, the VBR/CBR Cell Rate
Policing registers are used by the policing processor.
4
DROPUP
Indicates that this VC should be output to the
Microprocessor Cell Interface only (not to the Output
Cell Interface). Otherwise, the VC is presented on
Output Cell Interface (provided it is not a cell which is
filtered by the Routing Configuration Register).
3
AAL5
Identifies the VC as an AAL Type 5 Connection. This
enables AAL5 packet discard/tagging.
Note: If AAL5 policing is used, then only one GCRA
can be used (either GCRA1 or GCRA2). The GCRA
which is not being used must have its increment
field set to 0x00000.
2
Active
Identifies the VC as an active connection. If this bit is
set to 1, the VC is an active connection. Otherwise the
VC is an inactive connection. The bit is checked during
one-second servicing to determine if the connection is
still active. It is the responsibility of the microprocessor
to set and clear this bit during activation and
deactivation, respectively, of a connection.
1
Count User
If this bit is set, the CLP=0 and CLP=1 cell counts
include user information cells.
0
Count OAM
If this bit is set, the CLP=0 and CLP=1 cell counts
include OAM and RM cells.
The Status field provides a single location for the fast determination of the
connection state:
