7.1.2 OAM Flows Supported
28237-DSH-001-C
7.1.2.1 F4 OAM Flow
7.1.2.2 F5 OAM Flow
Table 7-2. VCI Values for F4 OAM Flows
The F4 OAM flow is the Virtual Path level, provided by OAM cells dedicated to
ATM layer OAM functions for Virtual Path Connections (VPCs). The F4 flow is
bidirectional.

The same pre-assigned VCI value is used for both directions of the F4 flow.
The F5 OAM flow is the Virtual Channel level, provided by OAM cells dedicated
to ATM layer OAM functions for VCCs. The F5 flow is bidirectional.

Table
Table 7-3. PTI Values for F5 OAM Flows
There are two kinds of F4 OAM flows which can simultaneously exist in a VPC:
• End-to-end F4 flow (used for end-to-end VPC operations
• Segment F4 flow (used for communicating operations information within
OAM cells for the F4 flow have the same VPI value as the user cells of the VPC.
F4 flow OAM cells are identified as F4 flow cells by a pre-assigned VCI value
There are two kinds of F5 OAM flows which can simultaneously exist in a VCC:
• End-to-end F5 flow (used for end-to-end VCC operations
• Segment F5 flow (used for communicating operations information within
OAM cells for the F5 flow have the same VPI value and VCI value as the user
F5 flow OAM cells are identified as F5 flow cells by a pre-assigned PTI code
