NOTE 3:Set the SW0-2 and SW0-3 as follows:
NOTE 4:When the system is a clock source office, set the SW0-2 and SW0-3 on all the BRT
cards mounted in PIM0 to OFF.

MP card will receive the 
clock signal from BRT0 at 
its PLO0 input.
When more 
than one BRT 
is provided.ON ON ON OFF OFF ON ---- OFF ONMP card will receive the 
clock signal from BRT0 at 
its PLO0 input, under nor-
mal conditions.
If a clock failure occurs with 
BRT0, MP card switches to 
the PLO1 input which gets 
clock from BRT1.

The figure in the SWITCH NAME column and the position in   in the SETTING POSITION
column indicate the standard setting of the switch. When the switch is not set as shown by the
figure and  , the setting of the switch varies with the system concerned.
NOTE 1:Set the groove on the switch to the desired position.
NOTE 2:When the power is on, flip the MB switch to ON (UP position) before plugging/
unplugging the circuit card. SW11 (DIP SW)

NOTE 3:The system can supply clock signals from two clock supply routes.
In normal condition, the system synchronizes to the clock signals supplied on the PLO0
of MP card via the Back Wiring Board, and if the clock signals fail, the clock supply
route takes over to PLO1 automatically. Set SW11-2 and SW11-3 as follows:
NOTE 4:When the system is a clock source office, set the SW11-2 and SW11-3 on all the BRT
cards mounted in PIM0 to OFF.
NOTE 5:Mount the BRT card which receives a source clock signals into PIM0. CONDITIONSBRT0 BRT1 BRT2 ---- BRT11

When one BRT 
is provided.ON ON
MP card will receive the clock 
signal from No.0 circuit of 
BRT0 at its PLO0 input.
If a clock failure occurs with 
No. 0 circuit, MP card 
switches to No. 1 circuit of 
BRT0.
When more 
than one BRT 
is provided.ON ON ON OFF OFF ON ---- OFF ONMP card will receive the clock 
signal from BRT0 at its PLO0 
input, under normal condi-
tions.
If a clock failure occurs with 
both No. 0 and No. 1 circuits 
of BRT0, MP card switches to 
the PLO1 input which gets 
clock from BRT1.
