3.5 High Speed Link Operation
High Speed Link (HSL) operation is supported in the following mode:
• Structured mode, where the data stream is framed as for conventional SS7:
— For T1, 8 bits in each of 24 timeslots are available for signaling.
— For E1, timeslot 0 is used for framing and 31 timeslots are available for signaling.
The implementation supports the use of both 7-bit and 12-bit sequence numbers as a
run-time configuration option.
The DSI SS7MD Board will support up to 4 HSL links, dependent upon the licensing.
3.6 Operation of the Thermal Sensor
Thermal Protection
The Dialogic
®
DSI SS7MDL4 Network Interface Board is a high performance, densely
packed, low profile PCIe board supporting high message rates. In achieving this
performance, the board may dissipate up to 17W and this must be taken into
consideration when selecting both the host chassis and the PCI Express slot in which to
install the board, refer to 0, “Appendix B - Thermal guidelines for server selection”. In
order to guard against hardware failure due to inadequate cooling from the host
chassis, the board is provided with an on-board thermal sensor which, in the event
that the board gets too hot, will shutdown the board.
