4-10 Configuring the Physical Ports
Uplink Mode, uplink operation mode
SDH
SONET
BER Threshold, controls activation of the Line BER SD and EED
Enable, the EED and SD statistics data is collected
Disable, the EED and SD statistics data is not collected
EED Threshold, Excessive Error Defect threshold in 1E-N, where N = 3, 4
or 5. The Excessive Error Defect is detected if an equivalent BER exceeds
selected EED threshold. The Excessive Error Defect is cleared if the
equivalent BER is better then 1E-(EED + 1).
10E-3, 10E-4, 10E-5
SD Threshold, Degraded Signal Defect threshold in 1E-N, where N = 5, 6,
7, 8 or 9. The Degraded Signal Defect is detected if an equivalent BER
exceeds selected SD threshold. The Degraded Signal Defect is cleared if the
equivalent BER is better then 1E-(SD + 1).
10E-5, 10E-6, 10E-7, 10E-8, 10E-9
J1 Path Trace Configuration controls the insertion of a user-defined test
string (trace) into the transmit path (J1 byte). A second menu opens to
define the following:
Enable/Disable, transmit path trace insertion is enabled or disabled
Actual Rx Path Trace, specifies the format of the path trace (up to 62
characters for SONET and up to 15 characters for SDH)
Tx Path Trace, transmit test string
Rx Path Trace, receive test string
Padding, select spaces or nulls.
Both sites must be configured the in the same manner.
J1 Path Trace.
Physical Failure Forwarding specifies whether the Ethernet traffic is
interrupted if an STM-1/OC-3c uplink failure is detected.
Enable the Ethernet traffic is interrupted if an STM-1/OC-3c uplink
failure is detected
Disable the Ethernet traffic is not interrupted if an STM-1/OC-3c uplink
failure is detected.
