3-4-2. Rear and Front panel connectors
All 4-Channel Port Cards install into the rear of the
MULTIPLEXER UNIT
. The back
plane provides both DC power to the 4-CHANNEL Port interface cards and routes signals
from the cards to the multiplexing circuitry. From here, the multiplexed signal is sent to the
Fiber Interface module installed in the front panel.
Figure 3-3 : Rear Panel Connections
The front panel of the MULTIPLEXER UNIT , holds the optical interface, LCD
display, menu keypad, LCD contrast trimmer and the status and alarm LEDs. On the optical
interface, two interface connector groups are provided for connection to either the primary
optical transmit and receive pair or to the redundant optical transmit and receive pair (if the
optical interface card has the redundant optical option). The front panel also provides the
connections to the RS-232 Console Interface (terminal mode) and to the LAN network for
SNMP control (when the SNMP option is installed).
