I – 22 The device MUST have the following indicator lights:
Power Ethernet DSL Internet
I – 23 All physical ports and bridged connection types on the device (e.g., Ethernet, USB, Wireless, HomePlug, HomePNA, 1394, etc…) MUST have a link integrity indicator lamp on the device (1 per port if a separate physical port is present or per connection type if a separate port is not present).
I – 24 [North America] The indicator lights MUST be labeled and in the order as indicated in I – 22 in a left to right or top to bottom orientation.
I – 25 [North America] Port indicator lights not identified in I – 22 MUST be placed between the “Ethernet” and “DSL” lights and labeled (order and text) as identified in I – 23.
I – 30 The device MUST have a “On/Off” power indicator light. The power indicator MUST function as follows:
Solid Green = Power on
Off = Power off
Red = POST (Power On Self Test) failure (not bootable) or
Device malfunction
A malfunction is any error of internal sequence or state that will prevent the device from connecting to the DSLAM or passing customer data. This may be identified at various times such after power on or during operation through the use of self testing or in operations which result in a unit state that is not expected or should not occur.
I – 31 The device MUST have an indicator light that indicates ADSL layer connectivity. This indicator MUST function as follows:
Solid Green = DSL good sync
Off = Modem power off
Flashing Green = DSL attempting sync
Flashing at 2 Hz with a 50% duty cycle when trying to detect carrier signal
Flashing at 4 Hz with a 50% duty cycle when the carrier has been detected and the modem is trying to train
I – 32 The device MUST have an Internet indicator light that indicates whether or not it has at least one DSL device-controlled session up.
This indicator MUST function as follows:
Solid Green = IP connected (the device has a WAN IP address from IPCP or DHCP and DSL is up or a static IP address is configured, PPP negotiation has successfully complete – if used – and DSL is up ) and no traffic detected.
If the IP or PPPoE session is dropped due to an idle timeout, the light will remain green if an ADSL connection is still present. If the session is dropped for any other reason, the light is turned off. The light will turn red when it attempts to reconnect and DHCP or PPPoE fails.
Off = Modem power off, modem in bridged mode or ADSL connection not present
Flickering Green = IP connected and IP Traffic is passing thru the device (either direction)
Red = Device attempted to become IP connected and failed (no DHCP response, no PPPoE response, PPPoE authentication failed, no IP address from IPCP, etc.)
For bridged mode, the indicator light MUST be off.
