24-Port FXS Analog Interface Module (WS-X6624-FXS)
The 24-port FXS analog interface module (WS-X6624-FXS) interfaces connect directly to standard
analog telephones or fax machines. The module interfaces supply ring voltage and dial tone
. The module
emulates the central office (CO) or private branch exchange (PBX), providing a service to an analog
telephone or fax machine. The telephone or fax machine connected through the FXS module operates as
if it were connected to a normal CO or PBX line.
The front panel LEDs are shown in Figure 12-5.
Note When installing the WS-X6624-FXS analog interface module in a chassis, you must have a system
ground cable attached to the chassis. Refer to the c7600 Series Installation Guide for the system
grounding cable installation procedure.
