6.2.5 Switch settings
Flash Eprom programming switches
• CA1.2 = ON -> Flash Eprom programming (card not operational)
• CA1.2 = OFF -> Card operational
Mandatory Position
100 Ohm adaptation straps
• CA1_i.1 = ON and CA1_i.2 = ON -> Access adapted 100 Ohms
• CA1_i.1 = OFF and CA1_i.2 = OFF -> Configuration for Y bus
(do not use for
base stations)
where i: Value from 0 to 15
Remote power supply configuration straps
• Swi_P* positioned at 1.2 = Remote power supply ON
• Swi_M* positioned at 1.2 = Remote power supply ON
• Swi_P* positioned at 2.3 = Remote power supply OFF
• Swi_M* positioned at 2.3 = Remote power supply OFF
where i: Value from 0 to 15
"_P": + 40 V or + 48 V
"_M": - 40 V or - 48 V
The two switches must be positioned on the same side: 1-2 or 2-3
DECT configuration switches
• Top side
• CA1.1 = ON -> Master mode
• CA1.1 = OFF -> Slave mode
• Bottom side
• CA2.4 = ON -> no M bit in S frame
• CA2.4 = OFF -> S frame M bit in service (base station synchronisation)
Factory setting
The CA2.4 switch must be set to OFF
to operate with DECT base stations.
The CA2.4 switch set to ON enables use in CBT mode (transparent B channel) for videophones,
routers and modems. In this case, there is no M bit in the S frame for all the card equipment and
it is not possible to equip synchronised DECT base stations with the M bit.
V11 clocks have 100 ohms adaptation resistors that must be connected:
• CA2.1 = ON -> resistor on SYN pair
• CA2.2 = ON -> resistor on SYNA pair
• CA2.3 = ON -> resistor on SYNB pair
Note:
DECT base stations and S0 terminals cannot be combined on the same LDS board
(DECT base station/S0 equipment combinations not allowed).
