RMCU Installation
1. Insert the RMCU (component side facing right) into the appropriate slot, and apply firm, even
pressure to ensure proper seating of the connectors.
2. Gently pull the unit outward. If the connectors are properly seated, a light resistance is felt.
3. Wire the RCMS jacks, J4 and J5, to the network CAMA trunks per Figure 10-9 on page 10-17.
4. Test the CAMA trunk and set the 3-dB Pad switches, SW101 and SW 201, for the appropriate
volume level.
