13.5 Connect the OAI Telephony Gateway to the MCU
1. The OAI Telephony Gateway must be connected as the last box in the MCU
chain. Connect the OAI Telephony Gateway to the OUT port on the MCU, using
the IPC cable supplied.
2. Double-check that the IN and OUT ports are correctly connected on all MCUs.
The first MCU will have no connection to the IN port; the last MCU is connected
to the OAI Telephony Gateway. The following diagram shows a chain of four
MCUs and the OAI Telephony Gateway.

Do NOT stack the MCUs and OAI Telephony Gateway on top of each
other. Units should be placed side by side physically touching the
adjacent unit.
3. Power up the entire system.
•
The Power and IPC LEDs on front panel of the OAI should be on. If the IPC
LED remains off, try replacing the IPC cable. If this does not correct the
problem, or if the Error LED is on, contact Customer Service.
•
All the MCUs should go through their usual diagnostic routine, and a unique
Box ID should display on the status LEDs of each MCU. If this does not
happen, recheck the IPC wiring.
