PackeTimePTP Module Configuration


The PackeTimePTP Module Configuration screen consists of the following status information sections:

Note: After making the changes on the Edit screen, you must click Apply on this screen for the changes to take effect. However, to not disrupt PTP service, you should make all changes first then click Apply only once. Each time you click Apply, the PTP card stops service for 30 seconds while it re-configures to its new settings. Click Refresh to update the display.

Each field of the module configuration screen is described in the table below.

Domain

Indicates the PTP Domain. Range = 0 to 255

Two Step State

Indicates whether the two-step clock operation is enabled. This panel is not displayed for legacy devices earlier than SSU 2000 6.3.

PTP Profile

 

Profile

Identifies PTP profile to ITU_G8265_1 or TELCOM_2008 selection. This panel is not displayed for legacy devices earlier than SSU 2000 6.3.

PTP SSM Option

 

SSM Option

This option is only available when PTP runs on ITU_G.8265.1. All the clock classes are defined according to the PQL (Priority Quality Level) value. Users are allowed to choose SSM Option 1 or Option 2 to determine the exact clock class. This panel is not displayed for legacy devices earlier than SSU 2000 6.3.

PTP Time Message

 

Second

Identifies PTP current time in seconds

Nano Second

Identifies PTP current and fractional time in nano seconds

PTP Management Attributes

 

Clock ID

Identifies PTP Clock ID which must be unique to avoid system conflicts and ensure interoperability.It is recommended that each active PackeTime PTP card's ClockID be set using the MAC-based value. The format is 0Xaaaaaaaaaaaaaaaa. The “a” represents a hex value. The 0X is a hex number token. The format contains a prefix hex number token (0X) following up to 16 hexadecimal characters.

Clock Class

Identifies the PTP master clock class

Clock Accuracy

Identifies the PTP master clock accuracy per the clock accuracy table

Time Traceable

Indicates if the time is traceable

Frequency Traceable

Indicates if the frequency is traceable

Domain

Indicates the 8-bit domain number
