Caution:

zSome measures are taken to protect voice modules. Still, you are recommended to install a special lightning arrester at the input end of each connection cable to obtain better lightning protection effect when the cable is led outdoors;

zRead the mark identifying a port before you connect a cable to it, making sure it is the correct port. Wrong connection tends to damage interface modules and even the Router.

zAs provisioned by Bell V, cables for FXS/FXO/E&M modules do not provide PGND wire. For this reason, a loop should be formed via the earth ground between the Router and the connected switch. In practice, the PGND wire of the switch can be connected to the chassis of the Router;

zTo ensure the EMC of the whole Router, you should connect the end of the cable with ferrite core to the Router.

Step 1: Plug one end of the cable into the RJ45 port on Router 2-Port FXS/FXO/E&M;

Step 2: Connect the other end of the cable to:

z

Telephone set, fax or AT0 loop trunk of telephone exchange, if you have installed an FXS module;

Subscriber line of telephone exchange, if you have installed an FXO module; E&M trunk of telephone exchange, if you have installed an E&M module;

Step 3: Power on the Router and check the LEDs for the slot on the front panel of the Router. Several seconds after the MIM is initialized, all the LEDs will blink once, meaning it has completed POST and is ready for work. If it fails to pass POST, the LEDs for it will keep OFF. In this case, contact your agent.
