17.2.3 OAM Controlling
OAM is a service for monitoring ATM connections. A total of five hierarchies (flow level F1
to F5) are defined for OAM information flow. The most important information flows for an
ATM connection are F4 and F5. The F4 information flow concerns the virtual path (VP) and
the F5 information flow the virtual channel (VC). The VP is defined by the VPI value, the
VC by VPI and VCI.
Note
Generally, monitoring is not carried out by the terminal but is initiated by the ISP. Your
device then only needs to react correctly to the signals received. This is ensured
without a specific OAM configuration for both flow level 4 and flow level 5.
Two mechanisms are available for monitoring the ATM connection: Loopback Tests and
OAM Continuity Check (OAM CC). These can be configured independently of each other.
Caution
The configuration of OAM requires extensive knowledge of ATM technology and the
way the
bintec
devices functions. An incorrect configuration can cause considerable
disruption during operation. If applicable, save the original configuration on your PC.
