TW-H6W1IR ISDN Remote Router
Installation 11
The TW-H6W1IR Front Panel
Names and descriptions of your router’s front panel LEDs are given
below:
POWER— Comes on as soon as you connect the router to the power
adapter and plug the power adapter into a suitable AC outlet.
TEST— Should be blinking if the router is functioning properly.
ISDN – LINK— Indicates that the router has an ISDN line connected
to the ISDN interface and it has been successfully initialized.
ISDN – B1 and B2— On if there is an active ISDN session on that
channel or if that channel is making or receiving a call.
ETHERNET – COL— Shines yellow when a collision occurs on the
LAN, that is, when two devices have attempted to transmit at the same
time.
ETHERNET – Uplink and 1 through 5— Each of these indicators
shines green when a connection to an Ethernet device is detected. The
indicator blinks when a transmission is received from the device, and
shines yellow when the device has been partitioned, that is, temporarily
isolated from the LAN because of excessive collisions (partitioning is a
required capability of all Ethernet hubs).
