Table 2-2 lists and describes the front panel LEDs on the MP-1xx.

LEDs; they only differ in the number of channel LEDs that correspond to the
number of channels.

2.2 MP-1xx Rear Panel
2.2.1 MP-10x Rear Panel
Figure 2-3 illustrates the rear panel layout of the MP-104. For descriptions of the MP-10x rear
panel components, refer to Table
2-3. For the functionality of the MP-10x rear panel LEDs, refer
to Table
2-4.
Tip 1: MP-10x (FXS/FXO) media gateways feature almost identical rear panel
connectors and LEDs, located slightly differently from one device to the next.
Tip 2: The RJ-45 port (Eth 1) on the MP-10x/FXO rear panel is inverted on the MP-
1xx/FXS. The label on the rear panel also distinguishes FXS from FXO
devices.
