• Level S-1.1
L-1.1
IN : −8 to −28 dBm/ −10 to −34 dBm
OUT : −8 to −15 dBm/ 0 to −8 dBm

Note: Operation of the TX SW and RX SW are not required in
1+0 system.
4 In HS system, set the TX SW to No.1 or No.2 to On condition at
transmitting end, (refer to
Chart 3-8)
5 At receiving end, set the RX SW to either No.1 or No.2 to On
condition,
6 Measure BER and confirm that the values are indicated as
follows:
Requirement: 1 x 10
–12
or less
7 At receiving end, change setting of t
he RX SW to opposite No.1
or No.2 from it in step 5 and confirm that the measured value
satisfies requirement given in step 6,
8 Change setting of the TX SW to opposi
te No.1 or No.2 from it
in step 4 and confirm that the measured value satisfies
requirement given in step 6,
9 At receiving end, change setting of t
he RX SW to opposite No.1
or No.2 from it in step 7 and confirm that the measured value
satisfies requirement given in step 6,
10 Restore all connections and controls to normal.
