3.3.2 FXS Blades
The FXS blade (referred to as Module in the device's management interfaces) provides the
FXS port interfaces. Each blade provides three FXS port connectors - 50-pin Telco
connector (Centronics type). Each connector provides 24 FXS interfaces and therefore,
each blade provides up to 72 FXS interfaces (3 x 24 FXS). The device can be housed with
up to four FXS blades thereby, supporting up to 288 FXS port interfaces (4 blades x 72
FXS). The FXS blades are available as spare parts. For replacing FXS blades, see Section
6.2 on page 48.
Each FXS blade provides a LED on the front and rear panel, as described in Section
3.3.4.3 on page 25.
