TS350 Introduction
The TS350 is a versatile, light, robust and feature rich ISDN basic
rate test set for use by telephone company technicians and
engineers when installing, commissioning and maintaining ISDN
basic rate lines.
The TS350 can make an ISDN speech, data, or BERT call. It can
monitor the protocol on the ISDN line and when used with the
Genius
powerful maintenance tool. The TS350 has an internal store of
messaging protocol at Layer 1, 2 and 3 which can be inspected on
screen.
The TS350 has comprehensive test suites for making outgoing and
incoming Bit Error Rate Tests (BERT) to assure line quality;
automatic or manual Teleservice support tests; and automatic or
manual Supplementary service provisioning tests.

For ease and convenience of testing combined analogue and ISDN
NTs (Network Termination), the TS350 has a PSTN analogue
telephone mode which supports Pulse and DTMF dialling, line
voltage measurement, and last number redial.
The TS350 has 2 rechargeable AA size NiMH batteries, which will
give approximately 12 hours battery life before you need to recharge
with the charger provided in your package.
The 100 x 64 pixel LCD graphics display has a backlight with
contrast adjustment to provide clear and detailed information on call
status, ISDN signalling in real time and stored test results.
Quick Start
Battery Charging
The AA size NiMH batteries are shipped uncharged so first you must
charge your TS350 NiMH batteries. Insert the dc plug of the mains
plug top dc battery charger into the dc socket at the bottom end of
the unit.
The TS350 will turn on automatically displaying the start up screen
sequence. Leave the unit to charge for approximately 16 hours.

If you are unable to recharge the NiMH batteries you can use
alkaline AA batteries if you wish. Alkaline batteries will not be
charged when using the dc battery charger.
Making a BER test
The TS350 has default values set as follows for the BERT test:
Bearer: Data (64k unrestricted digital information)
Loops: Bearer (for incoming BERT calls)
Pattern: 211-1 (Pseudo random test pattern)
Test time: 1 min
Test Thresholds; Errors: 1
You can use these values to make your first BERT test.
Note: For more detail on these options and their use see the appropriate
section in this User's Guide.
To make your first BERT call:
Step 1
Connect your TS350 with the RJ45 to RJ45 lead to the NT interface
S/T bus socket.
Step 2
Switch on the TS350 by holding down the key for 2 seconds. The
TS350 turns on, beeps and displays its start up screen sequence.
You will be presented with the Mode selection screen. Select ISDN
S - TE by pressing the (select) key. (Note all menu items that are
reverse contrast are selected using the key).

Note: For a self call the incoming B channel always auto answers and loops
the data regardless of the Loopbox menu settings which are intended for
incoming BERT calls from another tester.

turn on after each key press and turn off after one minute. If the
TS350 is powered from the dc supply, then the backlight will remain
on all the time.
The screen is split into three sections as shown below.

selected by pressing the key.
The bottom section displays Layer 2 frame types, TEI (Terminal
Endpoint Identifier) value, Layer 2 error messages, Layer 3 message
type, and Layer 3 error messages. These messages persist for 1S
and show the messaging activity as it occurs. The last 200 lines of
protocol are stored in the TS350 protocol trace store for inspection
after a test sequence has been performed.

The RS232 port has two functions.
Genius mode:
The normal mode of operation sends a Genius software compatible
binary output of the D channel protocol. In ISDN S-TE and ISDN UTE mode this protocol is the TS350 to Network protocol; in ISDN SMonitor passive monitor mode this is D channel protocol generated
by the TE and the Network.
Download mode:
When the Upgrade Windows PC application is run the serial port
receives the downloaded firmware upgrade to the TS350. To activate
this mode hold down the C key and turn on the unit until you hear the
beep. The screen will be blank until downloading starts.
Powering
The TS350 intelligently draws its power from available external
sources, drawing power from the batteries only when no other power
source is available.
The TS350 will draw power from:
• Normal power S bus PS1
• Restricted power S bus PS1
• S bus P S 2
• A powered U interface
• The 12VDC Power supply input
or if none of the above are available:
19
TS350® Basic Rate Euro ISDN Test Set
Free Datasheet http://www.Datasheet4U.com
• The 2 AA NiMH rechargeable batteries.
The TS350 will operate from any of the external power sources
without its batteries fitted, or when the batteries are flat.
When operating from an external power source the LCD backlight
will be on all the time the unit is operating, and the unit will stay on
regardless of the activity on the network interfaces.
When operating from the batteries, the backlight will turn on when
any key is pressed and timeout 1 minute after the last key press to
conserve battery power. If there is no network activity on the Network
interface connections, then the unit will switch off after 5 minutes.
This is to conserve battery power and to avoid battery discharge if
the unit is accidentally turned on.
Low Battery Warning
When the TS350 batteries become discharged, a battery low
warning of 3 sounder beeps will occur every minute until the unit
switches itself off. You will have approximately 5 minutes of testing
time left when the battery warning starts.
Charging the NiMH Batteries
To charge the NiMH batteries, insert the plugtop supply into a
convenient mains socket and insert the dc jack into the TS350 dc
socket. If the TS350 is not already on, it will turn on immediately.
Leave the TS350 to charge for approximately 16 hours. Whilst the dc
plugtop supply is on you will see a plug icon in the top right hand
corner of the LCD.
Using Alkaline Batteries
If you are unable to gain access to a mains supply to recharge the
batteries, alkaline AA batteries may be used. To change the batteries
remove the two battery cover retaining screws on the rear of the unit,
20

TS350 Configuration Modes
The TS350 can be used in four network interface operating modes
which are selected from the Mode menu.
ISDN S - TE
Connect the TS350 to the NT1 S interface socket using the RJ45
lead provided. In this mode the TS350 will act as an ISDN terminal
connected to the four wire S/T bus. The TS350 can carry out a BERT
test on any bearer, make a voice call, carry out manual or automatic
tests for Teleservice network support and common Supplementary
ISDN S - TE 1
ISDN S - Monitor 2
ISDN U - TE 3
PSTN 4

TS350® Basic Rate Euro ISDN Test Set
Free Datasheet http://www.Datasheet4U.com
service support. The mode is automatically selected if the S interface
is active or carries phantom power. If the S bus has no phantom
power and is deactivated the mode may be selected from the initial
Mode menu.
ISDN S - Monitor
In this mode the TS350 is "bridged" onto the S bus link between the
TE and the NT. The TS350 passively monitors D channel messaging
in bothTE to NT and NT to TE directions. The binary decode is
output on the RS232 port in real time for decode with the Genius
ISDN Protocol Analyser software. A simplified protocol trace is
shown on the screen scrolling in real time. The parameters to be
displayed are selected in the Setup menu in the sub menu Trace.
ISDN U - TE
Connect the TS350 to the two wire U interface with the crocodile
clips on the U interface lead provided. In this mode the TS350 will
act as an ISDN terminal connected to the two wire U interface and
replaces the NT1. The TS350 can carry out a BERT test on any
bearer, make a voice call, carry out manual or automatic tests for
Teleservice network support and common Supplementary service
support. The mode is automatically selected if the U interface is DC
powered or may be selected manually from the Mode menu.
PSTN
Connect the TS350 to the analogue interface with the crocodile clips
either connected directly to the pair or to a PSTN socket adapter. In
this mode the TS350 acts as an analogue test telephone and
supports DTMF or Pulse (loop disconnect) dialling, and line voltage
measurement. The mode is particularly useful when testing
combined analogue and ISDN network termination units (NTs). The
interface is automatically selected if a PSTN line voltage is detected
and no other interfaces are active or may be selected manually from
the Mode menu.

When the interface has activated the S or U interface LED will flash
green. Whilst activation is in progress or if it has failed, the LED will

To make a BER test (BERT), select the outgoing channel by entering
the channel number1 (either 1 or 2) for making the call and then
pressing the (select) key to select the channel. Either enter a
remote test number or for a self call test, your own number, and then
press the key again to setup the call.
