| Wan Link (Green)
Wan Activity (Yellow)
My explanations of the lights (if they are on):
Power: The
Modem/
Router is connected to a
power source properly
Alarm: Something is wrong with the router (Bad Thing)
Lan Link: The
Modem/
Router is properly connected to an
Ethernet NIC or a hub.
Lan Activity: The
Modem/
Router is communicating with your computer or internal network.
Wan Link: The
Modem/
Router is trained (connected to the CO)
Wan Activity: The
Modem/
Router is talking to the
ISP
And if they are not on:
Power: The
router is not receiving power
Alarm: All is well internally
Lan Link: Either the computer connected to the router is off, the
hub it is connected to is unplugged, or there is a problem with the
cabling
Lan Activity: Your Computer is not actively talking with the router (not necessarily a bad thing).
Wan Link: The modem is not
trained.
Wan Activity: The router is not currently talking to the
ISP.
And from the back:

|_______________________________|
What the ports are for:
ENET (Ethernet): Cat-5 network cable goes here
MGMT (Management): a piece of cable with an
RJ-45 connection on one end and a 9-pin serial connection on the other goes here (the RJ-45 end) used to
terminal in to the router.
WALL: Phone Cord goes
directly from here to the wall.
PHONE: You can connect a standard telephone into this jack.
Cisco has released two routers in the 67x series, the 675 and the 678. The 675 will only work in
CAP mode, while the 678 can do both
CAP and
DMT (a
bios flash on the router will switch it from one to the other).
The 67x series came into
Cisco when they acquired
Netspeed. For the operating system, the routers run an updated version of Netspeed's
NBOS called
CBOS. The current
CBOS version we're supporting at my company (DSL line support) is 2.4.1
Current rumor is that Cisco is getting out of the
CPE business, and the 678 is the last DSL modem/router they will release.
