2. Overview
RC953-FE4E1/8E1 (RC953-FX4E1/8E1) is Inverse Multiplexer which delivers Ethernet
services over existing TDM transportation network. These equipments can be used in
point-to-point topology and hub-and-spoke topology with RC953-8FE16E1 located in the
central office. RC953-FE4E1 (RC953-FX4E1) allows the transmission of fast Ethernet
over 4 bonded E1 circuits (8M) and RC953-FE8E1 (RC953-FX8E1) allows the
transmission of fast Ethernet over up to 8 bonded E1 circuits (up to 16M). There is optical
option for fast Ethernet port to provide an economical path towards extending the distance
of an existing Ethernet network. Additionally its advanced features such as automatic E1
link adjustment provide our carriers a cost-effective, flexible and reliable solution for
high-quality Ethernet Service delivery by using TDM network resources.

6.2.3. Connect the fast Ethernet interface
For electrical Ethernet interface: connect one end of the Cat. 5 UTP cable with Ethernet
router/switch and one end of the cable with the fast electrical Ethernet port of RC953. The
LNK indicator will be ON after correct connection.
For optical Ethernet interface: connect one end of the fiber with optical router/switch and
the other end with the optical Ethernet interface of RC953.
6.2.4. Connect the E1 cable
For unbalanced E1 equipment: use 75ohm unbalanced BNC cable.
For balanced E1 equipment: use 120ohm balanced RJ-45 cable.
6.2.5. Power on
If power supply is DC –48V, first connect middle end to PGND. Turn off Power Supply,
connect “-48V” end with the lower electric level cable, “0V” end with higher electric level
cable. Make sure no reverse connection, or no short circuited, and then turn on power.
When Power Supply is turned on, the PWR indicator should be ON.
6.2.6. Service configuration
Please refer to the command notebook and configuration guide of RC953-8FE16E1 for
the service configuration.

7. Q & A
If there are any problems during installation and using, try the following proposals. If the
problems still can not be solved, please contact distributors/agents for help.
z PWR, PWR1 and PWR2 are all OFF
Please check if power supply cable is connected and then check if the Power Supply
Board works normally
z SYS indicator is not flashing
The equipment is down, please restart the device or tell us. Please remember that the
SYS indicator will become flashing a little time later after powered on.
z E1 LOS indicator is ON
Loss of receiving signal occurs at e1 port. Check whether E1 cable is connected correctly;
if there is still LOS alarm please change the E1 cable otherwise there is something wrong
with the equipment.
z Ethernet LINK indicator OFF
Please check if the UTP cable is broken off first and then check if the equipment that
connects with RC953-8FE16E1 works normally. Please make sure that the correct
Ethernet cable is used.
