Troubleshoong Guide for IP/GPRS, GPRS/PSTN & Bi-Path IP/PST
FOR IP FAILURE FOR GPRS FAILURE FOR PSTN FAILURE
IP LED 201 indicates the IP
path is up
GPRS LED 202 indicates
the path is up if IP/GPRS. If
GPRS/PSTN the GPRS is
LED 201
PSTN LED 202 indicates the
PSTN path is up
Has the Quick Start Guide been
followed? Has the TCD been
Associated and Activated by
the ARC?

Has the quick Start Guide
been followed? Has the

Is the RJ45 physically
connected to the TCD and the
Router/Switch?
Is the Emizon antenna
physically connected to the
TCD and positioned
correctly?
Is the PSTN wired to T1 and
R1 terminals? Unscrew
White SLIC cover to check
the wiring
Is LED 301 next to the RJ45
Cable flashing? LED 301 only
indicates data is passing. LED
201 indicates the IP path is
signalling.
Take a signal strength on
the TCD by pressing
SW402 once, then Observe
the GS reading, Minimum
is 12, maximum is 31. The
GA and GR reading must
read 05. E.g. GS 27, GA 05,
GR 05
With a Multi-meter check if
there is approximately 50V
present on PSTN
connections between T1
and R1
Has the RJ45 cable been tested
for data? e.g. Can you connect
to the Internet? Try rebooting
the router for two minutes. Try
a speed test on a laptop
If a standard Antenna
(matchbox sized white) is
currently fitted and the
signal is below 12, try
installing an Emizon High
Gain Antenna Internally or
externally to improve the
signal strength. A 5M
Extension is also available
from CSL
Press SW401 for 5 seconds
to force a poll and wait 5
minutes, observe LED 202.
LED 202 should flash then
go solid on to indicate the
PSTN path is up
Does the TCD require a Static
IP Address? The TCD is DHCP
enabled by default. To apply a
Static IP Address, Subnet mask
and Gateway, use Emizon
Online Maintenance / Phone
app or call CSL
If the GPRS signal is still
low, relocate the High Gain
Antenna externally to
improve signal strength to
12 or above. The minimum
recommended signal is 12
and the maximum is 31.
The higher the GS reading
the better the signal. GS
99 indicates no signal
Can an outside call be
made with a Butt phone
tester?
