3.8 External Communication
An optional Analogue Telephone Gateway MP-114

satellite communication system using 2 or 4
analogue trunks. Optionally, MP-118 provides up
to 8 trunks.
The gateway and screw terminal block are
mounted on the left side wall inside the cabinet.
The Ethernet 1 output on the exchange backplane
is connected to the Ethernet input on the gateway.
A and B wires on pin 3 and 4 in the RJ11 FXO
outputs are connected to the FXO screw terminal
block.
The Gateway and LAN interface are ready
mounted and wired from the factory if included in
the customer’s order.
Connect the analogue trunks to terminals FXO 1-8
