(Continued) Master
and Slave
If the Master is unlit but the Slave is flashing, the Slave chassis is
synchronizing to the Master.
If the Master is unlit but the Slave is lit, the Slave chassis is synchro-
nized to the Master.
NOTE: If the Master chassis’s reference clock drifts or changes, the
Slave chassis will re-synchronize to the new clock. The Slave LED,
therefore, may flash during normal operation, even after it has initially
synchronized to the Master chassis.

Card On-Line Lit green to show functional readiness (e.g., the card is communicat-
ing properly with the rest of the system). If unlit, check for improper
connection; if still unlit, try another card or another card slot.
Circuit Busy Lit yellow to indicate that at least one of the 8/16 circuits is busy
(e.g., connected to a voice channel). Unlit when all the circuits are
idle.
NOTE: As of version 6.0, the Circuit Busy LED also lights when a
station residing on a DKSC-16 or DKSC-16+ is listening to back-
ground music.
Single-Line Card Card Active Lit green to show functional readiness (e.g., the card is communicat-
ing properly with the rest of the system). If unlit, check for improper
connection; if still unlit, try another card or another card slot.
Circuit Busy Lit yellow to indicate that at least one of the eight circuits is busy
(e.g., connected to a voice channel). Unlit when all the circuits are
idle.
