Clocking modes
Internal, external, or receive recovered
DTE rate
All 64k steps from 64 to 5696 kbps
Ethernet interface
Four RJ-45, 10/100Base-T, IEEE 802.3 Ethernet
Diagnostics
V.52 compliant (511) pattern generator and detector with error injection mode controlled by front-panel
switch. Local and Remote Loopback control either by a front-panel switch or from the DTE interface.
Status LEDs
Power (Green)
The Power LED glows solid during normal operation. At startup, during the POST, the LED blinks once
every second. If the POST fails, the unit does not enter normal operation, and the LED blinks once every
0.4 seconds.
DSL (Green)
The DSL LED glows solid while a DSL link is established. While the DSL link is training it blinks once every
second.
Link (Green)
The Link LED shows that there is an active physical network connection to the Console or an Ethernet device.
Activity (Green)
The Activity LED shows that there is data being transferred over that port. During a software upgrade proce-
dure, if the Activity LED is on for an unusually long time, there is a problem with the upgrade, and the device
should be restarted. The TFTP server should be checked (normal upgrades take about 10 seconds on a
100mbit link).
Configuration
Configuration is done with either externally accessible DIP switches, CLI or through the EOC (Embedded
Operations Channel) from a Model 3296RC G.SHDSL concentration card.
Power and power supply specifications
