•Type— Type of link. Possible link types are:
– HSL—The link uses the SS7-over-ATM (Asynchronous Transfer Mode)
high-speed protocol.
– SCTPIP—The link uses the Stream Control Transmission Protocol
(SCTP) IP transport protocol.
– Serial—The link uses the serial SS7 signaling protocol.
– Virtual—The link is a virtual link, which connects signaling point
instances running on the same device. SGM does not poll virtual links,
nor does it display real-time data or accounting statistics for virtual links.
•Congestion Level—Indicates whether there is congestion on the link. A link
is congested if it has too many packets waiting to be sent. This condition
could be caused by the failure of an element in your network.
Possible values for the Congestion Level field are:
– None—The link is not congested.
– Low—The link is slightly congested.
– High—The link is congested.
– Very High—The link is very congested.
Low, High, and Very High correspond roughly to equivalent ANSI,
China standard, and ITU congestion levels.
•Ignored—Indicates whether the link is to be included when aggregating and
displaying SGM status information:
– Clear the checkbox to include the link. This is the default setting.
– Select the checkbox to exclude the link.
This field can be edited by users with authentication level Power User (Level
2) and higher.
•Notes—Indicates whether there is a note associated with the link.
