Audio Program Interface
The MCAPI2 audio program interface is connected to P6 on the back
plane. Up to (4) four input modules can be installed in the MCAPI2.
The modules slide into the MCAPI2 and plug into an edge connector
as shown in Figure 10.
Card Frame/Circuit Card Installation
The MCMF card frame used in the cabinet-mounted system includes
a swivel mount to make it easy to install circuit cards. Turn the knob
on one end of the card frame to release the mount and tilt the frame
towards you.
Install the circuit cards in the order shown below. Slide the card into the frame to engage the edge connectors.
Align the locking tabs so that they close when the card is pressed into the connectors. Be sure that each card
is properly seated in the card edge connectors.
The cards will only fit one way!
Refer to the “Telephone Access Card” section on page 27 of this manual for instructions relating to telephone
circuit card installation and connections.
