Setting the Interfaces
Using Autosetup
Structured is not covered by Autosetup because searching through a
N OT E
PDH framing structure would take an unacceptable amount of time.
All line rates are searched for a signal. If a signal is found, a search for
framing pattern is made. All possible framing structures are searched
except for Structured.
If a framing pattern is found, a search for PRBS pattern is made.
SONET Input
If an STS-12 interface is chosen, the search will start on the STS-3
selected for test. All SONET line rates are searched for an electrical,
optical or binary signal.
If a signal is found, a search of payloads will start.
The payload search starts with STS-12c SPE in STS-12 and continues
with ATM, STS-1 SPE, VT-6, STS-3C, VT-2 and VT1.5.
For each payload a search is made to find a framing pattern. If a framing
pattern is found, a search for PRBS patterns is made.
TIP: If it is known that the signal of interest is in a particular STS-3 e.g.
number 3, then the Autosetup search can be speeded up by setting the
RECEIVE
for a signal will then start in STS-3 number 3.
