•
N:1 PVC mapping to PWE with non-unique VPI—This feature allows you to map one or more ATM
permanent virtual circuits (PVCs) to a single pseudowire. For more information, see
http://www.cisco.com/en/US/docs/ios-xml/ios/atm/configuration/15-2s/atm-n1pvc-mapping.html .
• Onboard Failure Logging—The Onboard Failure Logging (OBFL) feature collects data such as
operating temperatures, hardware uptime, interrupts, and other important events and messages from
system hardware installed in a Cisco router or switch. The data is stored in nonvolatile memory and
helps technical personnel diagnose hardware problems. For more information, see
http://www.cisco.com/en/US/docs/wireless/asr_900/feature/guides/onboard_failure_logging.html.
•
PTP Redundancy—PTP redundancy allows a PTP slave clock to select the best master from multiple
available master clocks based on clock quality and availability. For more information, see

.
• Time of Day Selection—You can use the time of day (ToD) and 1PPS ports on the Cisco ASR 903
Series Router to exchange ToD clocking. In master mode, the router can receive time of day (ToD)
clocking from an external GPS unit; the router requires a ToD, 1PPS, and 10Mhz connection to the
GPS unit. For more information, see
