Quiet Mode Enable. Set high to force the EDSP into the Deactivated state. Set
low to enable activation requests (see ACTREQ).
Activation Request (Master mode only - not used in Slave mode). When
QUIET is low, a rising edge on this pin initiates activation. The signal is ignored
after activation. In Slave mode this pin may be held low or left open.
Loop Number Control (Master mode) or Loop Number Indicator (Slave
mode). This indicator is transmitted from the Master to the Slave and can be
used for loop identification in systems that multiplex data onto two MDSL lines.
In Slave mode LOOPID is valid only when in the ACTIVE state. LOOPID=0
identifies MDSL loop 1 in accordance with the ETSI standard. LOOPID must be
set before the Master is activated. LOOPID may be originated in the EMDP only
when operating in modes 6 or 7.
Activating State Indication. ACTVNG is high when the EMDP is in the
Activating state.
