2.6 Rear Panel Connectors

The rear panel of the

FMUX04

supports the E1 and T1 interface connection, the AC or DC

power connectors, the power switch and the Ethernet connector for connection to the LAN
network for SNMP control (when the SNMP option is installed). The

FMUX04

routes the

signals from the 4 E1/T1 channels to the multiplexing circuitry and sends the multiplexed
signals to the Fiber Interface on the front panel.

2.7 Front Panel Switches, Connectors and Indicators

The front panel of the

FMUX04

, holds the optical interface, LED display, DIP switches and

RS-232 Console port/Alarm Relay connector. The optical interface is fixed at the factory per
order. The

FMUX04

supports single mode or multimode transceiver with SC, ST, or FC

connector in powers that support 2, 15, 30, 50 or 120KM reach. The front panel also provides
the Order Wire phone jack that can directly connect to any standard telephone set.
