WAN device (for example, a cable modem, DSL modem, or fiber modem). Note:
Only full duplex modes are supported.
PRI 0/0 RJ-45 connector providing E1 (2.048Mbps) or T1(1.533 Mbps) PRI interface, meet-
ing all requirements of ITU-T recommendations for G.703. Use a shielded E1 or T1
interface cable for 120 Ohm balanced connections to connect the SmartNode with
an NT or ET, e.g. a PBX or LE.
PRI 0/1 RJ-45 connector providing E1 (2.048Mbps) or T1(1.533 Mbps) PRI interface, meet-
ing all requirements of ITU-T recommendations for G.703. Use a shielded E1 or T1
interface cable for 120 Ohm balanced connections to connect the SmartNode with
an NT or ET, e.g. a PBX or LE.
PRI 0/2 RJ-45 connector providing E1 (2.048Mbps) or T1(1.533 Mbps) PRI interface, meet-
ing all requirements of ITU-T recommendations for G.703. Use a shielded E1 or T1
interface cable for 120 Ohm balanced connections to connect the SmartNode with
an NT or ET, e.g. a PBX or LE.
PRI 0/3 RJ-45 connector providing E1 (2.048Mbps) or T1(1.533 Mbps) PRI interface, meet-
ing all requirements of ITU-T recommendations for G.703. Use a shielded E1 or T1
interface cable for 120 Ohm balanced connections to connect the SmartNode with

•
Restart the unit with the current startup configuration—Press (for less than 1 second)
and release the Reset button to restart the unit with the current startup configuration.
•
Restart the unit with factory default configuration—Press the Reset button for
5 seconds until the Power LED (see

the unit with factory default configuration.
•
Restart the unit in bootloader mode (to be used only by trained SmartNode tech-
nicians)—Starting with the unit powered off, press and hold the Reset button as
you apply power to the unit. Release the Reset button when the Power LED starts
blinking so the unit will enter bootloader mode.
