Cdma 2000

O&M for PDSN: OMC-IP

  • Do not use the term CEM, as you will not find this in any other documentation.

  • In the 16.0 timeframe the OMC-IP will support the 7505 router, but does not provide specific support for “PDSN” as an application. There really is no product on the marketplace where this is true. Plan of record has UNO performing PDSN configuration mgmt, and support of PDSN’s SNMP interface.

  • 3. The hardware required is multiple platforms, not a single Ultra60 and multiple Cisco software products. Cisco Works 2K, and Cisco WanManager

  • O&M for PDSN is based on OMC-IPPDSN的操作和维护是通过OMC-IP实现的

  • OMC-IP

    • Provide element management facilities for Cisco equipments:对Cisco设备提供单元管理功能

      • MGX8850 Aggregation Node

      • Catalyst6509 Ethernet Switching

      • Inter-RAN Gateway (Cisco 3660 series router)

      • PDSN (Cisco 7505 router)

    • Integration of alarms and events from Cisco equipments into OMCR将告警和事件信息从Cisco设备集中传送到OMCR

    • Hardware: SUN Ultra60

    • Software: CiscoWorks2000
