GTT MAP Status Tab
To view detailed information about all GTT MAPs associated with the selected
signaling point, select the GTT MAP Status tab.
The GTT MAP Status table displays the following information for the selected
signaling point:
• Current Poll Interval—Poll interval used to collect data for the table.
• Last Poll—Time the last poll was run. This field initially displays the phrase
Polling device. After the first polling cycle, SGM populates this field with the
actual time of the last poll.
• Point Code—Primary point code for the GTT MAP.
• Subsystem Number—Primary subsystem number (SSN) for the GTT MAP.
• Point Code Status—Status of the primary point code. Possible values are:
–
Allowed
–
Prohibited—Either the point code cannot be reached, or the point code
is labeled Prohibited by the SCCP protocol.
• Subsystem Number Status—Status of the primary SSN. Possible values are:
–
Allowed
–
Prohibited—Either the remote subsystem cannot be reached, or the
subsystem is labeled Prohibited by the SCCP protocol.
• Congestion Level—MTP3 congestion level for the primary point code.
Possible values are:
–
No congestion—Corresponds to None. The link is not congested.
–
Congestion level 1—Corresponds to Low. The link is slightly congested.
–
Congestion level 2—Corresponds to High. The link is congested.
–
Congestion level 3—Corresponds to Very High. The link is very
congested.
Low, High, and Very High correspond roughly to equivalent ANSI,
China standard, and ITU congestion levels.
