OAM Cell Support
OAM cells are detected and transmitted by firmware. System software displays alarm indications
detected by the firmware. Additionally, loopbacks between the ATM-UNI and the ATM-CPE can be
established. ForeSight round-trip delay cells are generated by firmware upon software request.
System software deals with these OAM cell flows:
•
End-to-End AIS/FERF
Software displays on a per-connection basis.
•
External segment loopbacks
Software initiates loopback of ATM-CPE via user command. The SAR creates the loopback OAM
cell. External loopback cells received from the ATM-CPE are processed by the SAR.
•
Internal ForeSight round trip delay
Measures the RTD excluding trunk queueing delay on each ForeSight connection. Software
displays the result.
•
Internal loopback round trip delay
Measures the RTD including trunk queueing delay on each ForeSight connection. Software
displays the result.
•
Internal Remote Endpoint Status
These cells are generated by one end of a connection due to remote network connection failure
(Abit = 0). The other end detects these cells and reports the connection status to software, which
displays it.
These commands are associated with OAM cell status changes:
•
dspalms
•
dspcon
•
dspport
•
tstconseg
•
tstdly
