C.2 Card Default Settings
• Line Coding (E1-42 cards) defines the E-1 transmission coding type that is used.
• Line Length (DS3i) defines the distance (in feet) from the FMEC connection to the next termination
point.
• Line Type (E1, E1-42, and DS3i cards) defines the type of framing used.
• Port State (all cards) sets the port to one of the four available states (IS, OOS, OOS_MT, or
OOS_AINS), depending on whether you need ports in or out of service.
• SF BER Level (STM-N, TXP, and MXP cards) defines the signal fail bit error rate.
• SD BER Level (STM-N, TXP, and MXP cards) defines the signal degrade bit error rate.
• Enable Sync Messages (STM-N and MXP cards) enables synchronization status messages (S1 byte),
which allow the node to choose the best timing source.
• PJ VC4 Mon (STM-N cards) sets the VC4 that will be used for pointer justification. If set to 0, no
VC4 is monitored.
• VC4 IPPM Enabled (STM-N cards) enables intermediate-path performance monitoring on a node
for transparent monitoring of a channel that does not terminate on that node.
• Send Do Not Use (STM-N, TXP, and MXP cards) sends a DUS message on the S1 byte when
enabled.
• Far End Inhibit Loopback (DS3i card) enables DS3i cards to inhibit loopbacks on the far end.
• Payload Type (TXP and MXP cards) defines the type of client signal.
• Termination Mode (TXP and MXP cards) defines the type of termination (line, section, or
transparent).
• ALS Mode (TXP and MXP cards) sets the automatic laser shutdown feature to one of four available
states (disabled, auto restart, manual restart, manual restart for test).
• ALS Recovery Interval (TXP and MXP cards) sets the automatic laser shutdown recovery time
interval.
• ALS Recovery Pulse Width (TXP and MXP cards) set the automatic laser shutdown recovery pulse
signal width.
• FEC (TXP and MXP cards) enables or disables the FEC monitoring on the optical transport network.
• G.709 OTN (TXP and MXP cards) enables or disables the G.709 monitoring on the optical transport
network.
• FEC Thresholds (TXP and MXP cards) set the performance monitoring parameters for gathering
FEC performance data and detecting problems early.
• Optical Thresholds (TXP and MXP cards) set the performance monitoring parameters for gathering
physical optics performance data and detecting problems early.
• OTN Thresholds (TXP and MXP cards) set the performance monitoring parameters for gathering
OTN trunk-side performance data and detecting problems early.
• PM Threshold Settings (all cards) set the performance monitoring parameters for gathering
performance data and detecting problems early.
Note For more information about the performance monitoring parameters, refer to the “Performance
Monitoring” chapter in the Cisco ONS 15454 SDH Troubleshooting Guide.
