FOM16 Installation Description
FOM16-V2.0-20021114
3. Electrical Installation
3.1 FOM16 can be either AC- or DC-powered. If both AC and DC are fed at the time, The AC
power is selectable internally first and the DC power is used as a back up power source.
3.2 Use the rear left AC power connector to connect to an AC power outlet capable of furnishing a
supply voltage for either 110 or 220 VAC.
3.3 Use the rear right DC power connector to connect to a DC power source capable of furnishing
a supply voltage -48 VDC.
3.4 FOM16 consists of 16 E1 tributaries, i.e. CH1 ~ CH16. Each E1 tributary uses 4 pins, i.e.
Input Tip/Ring and Output Tip/Ring. Each rear DB-25 connector contains a 4-E1-tributary
group, that is, there are 16 pins designated for 4 E1 tributaries and 9 pins for frame ground
(FGND). The pin assignments are shown in the Fig.7 and Fig.8.
3.5 For the unbalance interface, each E1 tributary has two BNC connectors designated TXTIP
(transmit output) and RXTIP (receive input), as shown in Fig.9 and Fig.10.
