2.4OAM


The S1400 maintain a management information database. The database is accessible separately from craft interface of standalone type STU-C and STU-R. The database includes provisioning parameters, alarm/status and Performance information. OAM (Operation, Administration and Maintenance) of the Scorpio 1400 is listed below:

  • UNMS manages S1400 system via SNMP agent interface and provides a user-friendly GUI-based operational interface under PC / Windows or HP Open-View systems.

  • Support standard MIB RFC 2495 for DS1 / E1, and RFC3276 for SHDSL interface.

  • MIB follow the standard RFC1157, RFC1212.

  • CID Console: The S1400 has an EIA-232 connector for user-friendly menu-driven CLI operation.

  • SNMP management message interface V1.0.

  • The provisioning parameters for each SHDSL System were provided through the CID.

  • The provisioning parameters for each SHDSL System includes loop attenuation threshold, SHDSL SNR Margin threshold, performance parameter threshold, SHDSL power back off, data rate or line rate, clocking architecture, DS1/E1 interface and DS1/E1 frame format, line code, etc.

  • The S1400 was provided with a nonvolatile memory stores all provisioning parameters.

  • A default configuration setup option was provided. The SHDSL System can be set to this status.

  • The SHDSL was provided with an EOC for OAM data and signals transmission, including configuration, fault message and performance monitoring data, and loopback control signal, etc. The EOC complies with section 9.5 of ITU-T G.991.2.

  • Remote control / monitoring S1000 via Telnet and Ethernet

  • Remote in-band control/monitoring CPE via G.SHDSL EOC

  • Remote Software Upgrade: Remotely via Ethernet port with TFTP protocol, Locally CID console terminal with XMODEM protocol.

  • Automatically and manually configuration backup and restoration to / from local nonvolatile memory

  • Support Alarm Surveillance function, any event detected will be reported to Craft Interface Device (CID) and UNMS automatically. The alarm reports include managed object, alarm/event type, alarm severity, day/time occurred.

  • Support Performance Monitoring function

  • For test and diagnostic purpose, a simulated noise sources and test loop are built in, the S1000 / S1400 system provides various loopback paths, which are depicted in Figure 5-1 and Figure 5-2.

  • For each STU-C and STU-R, the built-in PRBS generation and detection are provided for loopback performance test on per channel basis. Test results are displayed. The supported PRBS patterns include 211-1, 215-1, QRSS, 220-1, 223-1

  • ITU-T V.54 in-band activated and deactivated loopback code words are provided for end-to-end loopback function, the details are depicted in Figure 5-3.

  • BER measurement is performed for both directions of transmission and the tests in each direction will be performed in full duplex mode with both STU-C and STU-R simultaneously transmitting data. The test loops defined in ITU-U G.991.2, are individually inserted between the STU-C and the STU-R.

  • The noise level test procedure complies with section A.3.1 of ITU-U G.991.2.
