Interface Modules
Interface modules are voice modules inserted in the slots provided on a
Universal Analog Voice Module supporting FXS, FXO, E&M and Voice/Fax
Switch modules. The type of interface module selected will depend on the
signaling required (see page 6-2).
Removing an Interface Module
Figure 6-10. Removing the Connector Cover
1. Facing the rear of the voice/fax module, remove the screw on the left side
of the connector cover with the Phillips screwdriver (see Figure 6-10
above).
2. Unhinge the right tab from the slot on the right side of the interface
module, then remove the connector cover. Save the screw.
3. Disconnect any modular cables from the RJ-11 connectors or unplug the
terminal block from the interface.
4. Unscrew the two spring-loaded captive screws with the medium-sized,
flathead screwdriver.
5. Grasp the interface module firmly and slide it slowly toward you until
it is free of the Universal Analog Voice Module (see Figure 6-11 on page
6-8).
Caution:
!
The interface module must not be inserted into, or removed from
the unit, while the unit is operating. This could cause damage to
the unit or cause interruption of network services or both.
