do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's
path protection feature, which may be used in any topological network configuration. Cisco does not
recommend using its path protection feature in any particular topological network configuration.

  • Page 22 An APS Inconsistent alarm means that an inconsistent APS byte is present. The SDH overhead contains K1/K2 APS bytes that notify receiving equipment, such as the ONS 15310-MA SDH, to switch the SDH signal from a working to a protect path when necessary. An inconsistent APS code occurs when three consecutive frames contain nonidentical APS bytes, which in turn give the receiving equipment conflicting commands about switching.

  • Page 43 The Interconnection Equipment Failure Working ONS 15310-MA SDH Payload Bus alarm indicates a failure in the main payload bus between the ONS 15310-MA SDH and the reporting Ethernet card. The controller card and the Ethernet or electrical card are no longer communicating.
  • Page 44 RPRW, page 121, to indicate the failure. In a typical scenario that triggers Cisco proprietary RPR protection, the errored node raises RPRW, and SDH or data errors such as TPTFAIL, page 139. If, however, a packet-over-SDH (POS) port is placed in down administrative state, the card will raise an RPRW without raising any SDH B3 bit alarms or data alarms.
