Disable power supply: Different
function in LT and NT modes. LT: the
DISS pin is set to (1) with the C/I
command "LTD". NT: the DISS pin is
set to (1) after receipt of MON-0 LBBD
in Auto mode.

PS1
I
Power status (primary): Different
function in LT and NT mode. LT: (1)
indicates that the remote power is
switched off. (1) on PS1 results in C/I
message "HI". Clamp to low if not
used.
NT: (1) indicates that prim. Power
supply is OK. The pin value is identical
to the overhead bit "PS1" value.

PS2
I
Power status (secondary): Different
function in LT and NT mode. LT: the
current feed value is transmitted (8 bit
serially) from a power controller. Read
the value with MON-8 "RPFC". NT: (1)
indicates that secondary power supply
is OK. The pin value is identical to the
overhead bit "PS2" value.

Crystal OUT: 15.36-MHz crystal is
connected. Suitable load capacitances
should be connected in parallel. Their
value depends on the crystal chosen
and board Layout. See "Oscillator
Circuit and Crystal", page 252 for
