NTU Alarms and Status Reports
The 1643 AM / 1643 AMS provides enhanced PM support for third party NTUs. It
supports a two port Ethernet SHDSL modem (NTU) which is connected via 1 to 4
parallel TU-12s over SHDSL mapped links. The Enhanced NTU ETH LAN port PM
counters are available via the QD2-Lite extension. The Ethernet traffic bandwidth is
optimized by GFP-F encapsulation and VC-12-Xv virtual concatenation using LCAS.
The 1643 AM / 1643 AMS supports the following enhanced NTU alarms and status
reports.
• SDH port status
Note that dEQP, dINTB, dNAE, dDEG-N, dAIS-U, dLOP-U, dPLM-V, dTIM-V,
dRDI-V, dDEG-V, and dUNEQ-V are supported in Release 6.0.
• Ethernet port status
Note that dANM and dLOS are supported in Release 6.0.
• Updated Encaps and VCG status: TLCR, PLCR, FOPR, TLCT, PLCT, FOPT, LOA
Note that dLOF-G, dPLM-G, SQM
Remote SHDSL Power Supply (RPS) Support
The 1643 AM / 1643 AMS manages an external Remote SHDSL Power Supply (RPS)
box via the MDI/MDO interfaces. Note that remote power supply must be set to
’managed mode’ by the DIP switch=ON in the power box.
The Lucent OMS can also be set to ’managed mode’ for the remote power supply.
The 1643 Access Multiplexer AM / 1643 Access Multiplexer Small AMS supports the
following remote power supply provisioning functions.
•
Restart_cmd: Restarts the RPS module after forced shutdown
• Enable/Disable RPS related alarms (per port and not per alarm). This provisioning
is used to suppress alarms generated by the RPS module.
The 1643 Access Multiplexer AM / 1643 Access Multiplexer Small AMS remote
power supply module supports the following alarms.
• RPS power failure (per box)
• Overl: Overload (per port)
• OpenC: Open circuit (per port)
• FSD: Forced shut down (per port)
• Leak: Leakage asymmetrical (per port)
• HVolt: Overvoltage alarm (per port)
Note that the external power supply module has a maximum number of 12 SHDSL
ports.
Note that the MDI interfaces 1...4 and MDO interfaces 1...4 will not function as
normal when the RPS is set to managed mode.
