Maintenance testing
For circuit testing during maintenance operations, the system provides:
• Loopbacks on incoming E1 , DS1, E3, DS3 and X.21 signals (loopbacks on
E1/DS1/X.21 are exclusive)
• Loopbacks on outgoing E1, DS1, E3, DS3, SHDSL and X.21 signals
• Cross-Connect loopbacks at AU level
• NT1 (Network Termination) loop-back on a 2 Mbit/s line dedicated to ISDN.
SDH performance monitoring
Provisioning and retrieval of performance monitoring parameters are derived from the
overhead bytes (SOH, POH of each VC) and are in accordance with ITU-T
Recommendations G.874 and G.826. This is accomplished via Lucent OMS and
ITM-CIT. Performance threshold counts are user settable. Each managed NE has a
current data register for 15 minutes or 24 hours.
The following parameters are monitored:
• Severely Errored Seconds (SES)
• Errored Seconds (ES)
• Background Block Errors (BBE)
• Unavailable Seconds (UAS).
Ethernet performance monitoring
Ethernet (LAN and WAN) performance monitoring information can be derived from
bytes sent, bytes received and packets dropped. This information is available in 15
minutes or 24 hours registers.
ISDN performance monitoring
ISDN Performance monitoring information can be derived for 2 Mbit/s signal from
pN_EBC (Near-end Errored Block Count).
