MediaType
|
mmf (multimode fiber), smf (single-mode fiber), or ds3 (direct signal, level 3)
|
LineSpeed
|
For OC-3c, the operating speed is 155.52 Mb/s; for OC-12c, it is 622.08 Mb/s; for DS-3 it is 44.736 Mb/s.
|
NumVpiBits
|
For OC-3c, 11 bits split between NumVpiBits and NumVciBits. NumVpiBits cannot exceed 6 bits for OC-3c.
For OC-12c, 13 bits split between NumVpiBits (default is 4) and NumVciBits (default is 9). NumVpiBits cannot exceed 8 bits for OC-12c.
For DS-3, 12 bits split between NumVpiBits (default is 4) and NumVciBits (default is 8). NumVpiBitscannot exceed 7bits for DS-3.
|
NumVciBits
|
This field is read only. It takes remaining bits from NumVpiBits. For example, if NumVpiBits is 3 for OC-3c, then NumVciBits is 8.
|
ScrambleEnable
|
Sets the port to scramble the data by clicking the box.
|
FramingMode
|
Sets the framing for the port to:
- SONET (Synchronous Optical Network), the standard format used in North America.
- SDH (Synchronous Digital Hierarchy), the standard format used worldwide except in North America.
- Any of the following Digital Signal, Level 3 (DS-3) formats:
|
ClockSource
|
Sets the clock source for the port to:
- loopTimed, which means clocking is derived from the SONET line.
- freeRunning, which means clocking is derived from the on-board clock.
Note: If you have two connected s, you must set both to freeRunning or one to freeRunning and one to loopTimed; do not set both to loopTimed.
|
LoopBackMode
|
Sets the loopback mode to:
- off
- internal
- external
- ds3PayloadLoop
- ds3DiagLoop
- ds3LineLoop
|
MacAddress
|
MAC address assigned to a particular interface.
