Epoch-M1C RF Repeater

User Manual V1.1

1. Introduction of Epoch-M1C

1.1 Overview

Epoch-M1C series repeaters enhance in-building wireless coverage in the most
effective and cost efficient way. For its intelligent design and versatility, Epoch­M1C series repeaters are the ideal choice for indoor wireless coverage problems.
An Epoch-M1C series repeater can be used as a stand-alone repeater with
passive antennas connected to it or it can also be used as a feeder repeater to a
DAS (Distributed Antenna System).

1.1.1 Highlights

• 20 dBm Composite Output Power

• 80 dB Gain

• 25 dB AGC Range @ 0.5 dB Step

• Can Set AGC Output Power Level

• Band Selectable via Software

• Can Support Non-Contiguous Bands

• Supports Embedded Wireless Modem

• Supports Network Management Monitoring System via SNMP

• Supports Auxiliary Alarming for a DAS or a Third-Party Repeater

1.1.2 Special Features

User Manual V1.1

1. Server Antenna Port
One end of the coax cable will connect to the “Server Antenna Port” of
Epoch-M1C while the other end of the cable will connect to the server
antenna which is pointing towards the intended coverage area.

2. Power LED
The Power LED will be lit Green if the power is turned on and will be not
lit if the power is turned off.

3. Wireless Modem Access
You can manually place or take off the wireless modem.

4. Donor Antenna Port
One end of the coax cable will connect to the “Donor Antenna Port” of
Epoch-M1C while the other end of the cable will connect to the donor
antenna which is pointing towards the BTS.

5. VFD Display
In this display, you are able to view the repeater vitals in each link (e.g.
RSS, Gain, Output Power & Alarms).

6. Alarm LED
If there is an alarm, the Alarm LED will be lit Red. If there is no alarm the
LED will not be lit.

7. VFD
VFD stands for “Vacuum Fluorescent Display.”

** Please refer to Appendix B for more detailed information on how the
VFD button operates.

8. USB Interface
For management and troubleshooting purposes, you can connect your PC
to the Epoch-M1C via a USB cable.

9. Dry Contact Interface (AAI)
AAI stands for Auxiliary Alarm Input. It acts as the interface between the
two devices (Epoch-M1C & DAS or third-party repeater) so that it can
pass alarming information from the third-party device to the Epoch-M1C.
The following table illustrates the PIN assignment which can be
customized according to the third-party device so that proper alarming
parameters are passed to Epoch-M1C.

AGC Mode
AGC (Auto Gain Control) adjusts the variable gain of the repeater to ensure a
constant specified output power of 20 dBm. The functionality of the AGC feature
is assured under the condition that the input BTS signal is within the specified
AGC range (-60 to -35 dBm => assuming AGC Level is set to 20 dBm) and that
sufficient isolation exists between antennas (≥ 93 dB). By default, the
box is checked. To manually change the gains in both the links,

AGC ON

AGC ON

must

be unchecked.

If

AGC ON

is checked and

Uplink Tracking ON

is unchecked, the user can specify
the AGC level in the downlink and in the uplink respectively @ 0.5 dB step (0 to
20 dBm). By default, the AGC Level is set to 20 dBm in each link.

Downlink/Uplink HPA Mode
The HPA mode enables the user to turn the HPA on or off. If the HPA is turned
off on either link, the Epoch-M1C will not operate properly. Both HPAs needs to
be turned on for the RF portion of the repeater to work in both directions
(downlink and uplink). By default, the

Downlink/Uplink HPA ON

boxes are

checked.

Either or both HPAs can be turned off for troubleshooting purposes during an
installation process.

Advanced RF Technologies, Inc. Proprietary Document Page 18 of 38

Epoch-M1C RF Repeater

User Manual V1.1

Uplink Tracking/Offset Modes
Uplink tracking mode enables or disables the

Uplink Tracking ON

feature that
sets the gain in the uplink equaling to the gain in the downlink. The tracking
gain offset is the difference between the uplink and downlink gains. For
example, if the downlink gain is 80 dB, the
the

Uplink Tracking Gain Offset

is set to 3 dB, the uplink gain would be 77 dB.

Uplink Tracking ON

is checked, and

By default, the
the default

Uplink Tracking ON

Uplink Tracking Offset

box is not checked. If it was checked, then

is set to 3 dB. This means that the uplink gain

will track the down link gain and will be 3 dB less.

Downlink/Uplink Gain
The gain of the Epoch-M1C is the ratio of the input signal to the output signal.
The gain may be set in both links.

** The manual gain option is disabled when the AGC ON box is checked.

Reboot

By clicking the “Reboot” button, similar to how the operation works in a PC, the
control board of the repeater will restart itself.

Factory Setting

Clicking on the “Factory Setting”

button resets the settings of the repeater to the

In the event of a hard fail alarm, the control board will shut down the HPA (both
uplink & downlink) for 30 seconds and then turn on the HPA to check for a repeated
hard fail occurrence. If the hard fail alarm persists for up to four consecutive
occurrences, the control board will shut down the HPA for 20 minutes (total of five
consecutive hard fails). After 20 minutes, the HPA will automatically come back alive
and the control board will check if the Hard Fail alarm has cleared. If it has not, the
same process will continue as mentioned above.

** The alarms can also be viewed on the front panel of the repeater by clicking

failure and an over power hard failure:

If the threshold value for the downlink over power parameter is set to 22.0 dBm
(factory set value), a Hard Fail alarm would occur if the downlink over power
value was greater than 22.0 dBm (20 dBm is the maximum composite power
allowable). Similarly, a Soft Fail alarm would occur if the downlink over power
value was greater than 21.0 dBm but less than 22.0 dBm. Vice versa, the same
example is also applicable in the uplink side.

3 Maintenance Guide for Epoch-M1C

3.1 Periodic Inspection Checklist

Check for loose connections to the repeater and antennas. If connections are
loose, make sure that all connections are tightly fastened.
Cables and connectors are in good condition.
Ensure that the repeater brackets are in good condition and that the repeater is
securely fastened.

3.2 Preventive Measures for Optimal Operation

3.2.1 Recommendations

• Perform the

Periodic Inspection Checklist

quarterly or semiannually.

3.2.2 Precautions

• Do not operate the repeater with the antennas in extremely close

proximity as this may cause damage to the repeater.

• Do not change parameters unless instructed to do so by an authorized

supervisor.

• Do not move the repeater unless instructed to do so by an authorized

supervisor.

• Do not detach any cables to the repeater unless repair of respective

components are necessary.

The repeater is not receiving any commands from the
software. In this state, the repeater is either processing or
executing a command. Wait for a few seconds for the Rx LED
to blink periodically.

The repeater is not receiving any commands from the
software. Ensure that the repeater is tuned on and check for
proper USB port connection.

The USB port can not send or receive data. Check if the USB
driver has been installed and also verify if the physical
connection on both ends of the USB cable is secure. Ensure
that the repeater is turned on.

You would need to install the driver for the USB cable which can be
found with the CD that comes with the repeater.

Check if the power switch is turned on. Also verify if the power cord is
securely connected to the repeater. Make sure there is no power
outage.

The very first time during installation, once you connect the USB cable
to the repeater and the laptop, the PC will automatically detect a new
hardware has been added in the system and will prompt you to install
the driver which can be found in the CD. The driver needs to be
installed only once.

Check that the donor and server antennas are connected to the proper
antenna ports on the repeater.

Reposition or rotate the donor antenna until a stronger signal is
received.

Increase the separation between the donor and server antennas by
moving the antennas around or by rotating them.

Check the cabling because RF signals may be leaking and also verify
that the connectors are tightly secured.

Add an attenuator after the donor/server antenna to reduce the strong
donor/server signal coming into the repeater.

If the repeater is connected to a DAS, there is a good chance the DAS
system could cause a strong signal to come in on the uplink side of
the repeater, causing an

Try to reduce the AGC Power Level using the GUI software.

An oscillation in the system could cause this alarm. Check if there is
sufficient separation between the donor and the server antennas.
