  • Page 212 In this chapter, “cross-connect” and “circuit” have the following meanings: Cross-connect refers to Note the connections that occur within a single ONS 15327 to allow a circuit to enter and exit an ONS 15327. Circuit refers to the series of connections from a traffic source (where traffic enters the ONS 15327 network) to the drop or destination (where traffic exits an ONS 15327 network).

    The I-Temp symbol is displayed on the faceplate of an I-Temp compliant card. A card without this Note symbol is C-Temp compliant. 13.1 Overview The Cisco ONS 15327 uses common control cards, mechanical interface cards, optical cards, and an Ethernet/fast Ethernet card. This overview provides a summary of the cards. Figure 13-1 shows the ONS 15327 slot assignments.
  • Page 384: Common Control Cards

    Because no bandwidth is reserved for protection, unprotected schemes maximize the available ONS 15327 bandwidth. On the ONS 15327, only OC-N cards can run unprotected. DS-N cards are protected by default because of the automatically created protection group, XTCProtGroup.

    14.3.1 Conditions When an SA failure is detected, the ONS 15327 also sends an AIS downstream. When it receives the AIS, the receiving node sends a remote failure indication (RFI) upstream. AIS and RFI belong in the conditions category and show up on the Conditions window of the ONS 15327. However, unlike most conditions that are nonalarmed, Telcordia classifies these conditions as not reported (NR).
  • Page 417: Severities

    Minor alarms, such as Fast Start Synchronization (FSTSYNC), do not have a serious effect on service. FSTSYNC lets you know that the ONS 15327 is choosing a new timing reference because the old reference failed. The loss of the prior timing source is something a user needs to look at, but it should not immediately disrupt service.
  • Page 418: Ais-p

    Alarm Troubleshooting Alarm Procedures The ONS 15327 detects an AIS in the SONET overhead. This alarm is secondary to another alarm occurring simultaneously in an upstream node. An incomplete circuit path causes an AIS. For example, it is raised when the port on the reporting node is in service but a node upstream on the circuit does not have its OC-N port in service.

    To determine the validity of the K byte signal, examine the received signal. Use an optical test set capable Step 1 of viewing SONET overhead.
