Table 8: Description of switches SW3 to SW6 on the LD4 RJ card
CA2.1 SWITCH EXPLANATION
ON Leave set to ON position. If the LD4 RJ card is fitted in a synchronising slot,
the ON position allows the PBX to take the ISDN network clock as
reference clock. In a non-synchronising slot, CA2.1 has no effect. The
synchronising positions in an XL cabinet are the locations 1-00 to 1-05. For
an XS cabinet, all positions are synchronising. On XS12, the backplane
does not transmit the network synchronisation (synchronising slots are T0
interfaces built into the UCT card).
OFF Do not set it to OFF position (in OFF position, the ISDN clock is not taken
as reference, whatever the slots).
SWITCH CA2.2 EXPLANATION
M Position not allowed
S Slave LD4 RJ: To be set to position S on all LD4 RJ cards (LD4 RJ card
always slave).
SW3 Remote power supply for interface 3
SW4 Remote power supply for interface 2
SW5 Remote power supply for interface 1
SW6 Remote power supply for interface 0
