Port class guidelines and default settings
There are different recommendations and default settings for the physical port, the E_Port, and the
FOP_Port and FCU_Port. Please refer to the following sections and plan carefully before you begin
configuring the port.
• “Physical port setting guidelines”
• “E_Port subclass setting guidelines”
• “FOP_Port and FCU_Port subclass setting guidelines”
NOTE
E_Ports and VE_Ports are not supported in Access Gateway mode.
Physical port setting guidelines
For the physical port, use the default settings listed in Table 15 for all areas and alarms except for
Invalid Transmission Words and Invalid CRC Count. For Invalid Transmission Words and Invalid CRC
Count, the alarms should be set at two points: a low boundary and a high boundary, with the goal to
alarm as the number of invalid words per minute rises above the low boundary and again as it rises
above the high boundary. it is recommended that you set the high boundary at 25 and set the
alarms to alert the error log any time this high boundary is exceeded.
Port class default settings
