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
GeniusTM ISDN Protocol Analyser software it makes an extremely
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.
6
TS350® Basic Rate Euro ISDN Test Set
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 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
•
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® Basic Rate Euro ISDN Test Set
take off the battery cover and replace the batteries. The TS350
battery charging circuit will not charge alkaline batteries.

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
21
TS350® Basic Rate Euro ISDN Test Set
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.

Bearer: Selects the bearer selected in the Bearer menu (above) that
will be automatically looped upon receipt of a compatible call. The
incoming receive pattern is looped back onto the transmit side of the
bearer channel. This function will operate whatever the test menu
state when an incoming call is received, even if a test call is in
progress on another channel.
In this mode the TS350 cannot clear the incoming call, which must
be cleared by the remote tester. This is to avoid tampering when the
TS350 is left unattended.
All: Any incoming call on any bearer is looped.

None: No incoming calls are looped. In this mode all calls are
manually answered. Voice calls operate normally.
ManPRBS: If an incoming call compatible with the selected bearer in
the Bearer menu is received the TS350 will ring. When you answer
the call with the ↵ key, the TS350 sends its own PRBS pattern as
selected in the Pattern menu. This mode allows the transmit and
receive directions to be independently tested for errors end to end.
After answering the call you are presented with the test results
screen.
In this mode you can wait for the remote tester to finish the test or

Passive Monitor
The TS350 Passive Monitor mode allows you to monitor Layer 1 and
the D channel protocol at Layer 2 and Layer 3 in the TE to NT (User)
and NT to TE (Net) directions on the S/T bus. In this mode the
TS350 must be bridged onto the link between the NT and the TE
which may be an ISPBX or multiplexer. You can do this by using
appropriate adapters e.g. a dual outlet RJ45 adapter.

PSTN Testing
The TS350 can test analogue PSTN lines and ports. This mode is
very useful when testing combined ISDN S and analogue V5.1
combined NTs. The TS350 can also be used on regular analogue
PSTN lines.
The TS350 has the following PSTN modes:
•
•
•
•
Line monitor - "on hook"
Talk mode - "off hook"
DTMF or pulse/loop disconnect dialling
Line voltage measurement showing polarity reversal
When in the Mode menu, inserting the PSTN line cord provided will
auto select the PSTN menu if a line voltage is detected. If a voltage
is not detected, or you also have the S interface connected, then you
must manually select PSTN from the Mode menu.

TS350 Firmware Upgrade
The TS350 firmware is stored in FLASH memory, which allows you
to upgrade the firmware release from your PC. The latest firmware
releases are available on the Harris web site or you may purchase
feature upgrades on CD.
To upgrade your TS350 carry out the following steps.
Step 1
Download the upgrade file from the Harris web site and store it onto
your hard drive in a directory of your choice. Or copy the upgrade
executable file from the Upgrade CD. For example the path:
C:\Harris TS350\TS350Upgrade.exe
Note: Dependant upon the type of upgrade, you may
need to get a security access code from your Harris
representative to enable you to access the TS350
download area of the Harris web site.
Step 2
Use the serial cable provided to connect your TS350 RS232 port to
the COM1 port on your PC.
Note: If COM1 is not available use another COM
port.
Set the COM1 port baud rate to:

TS350® Basic Rate Euro ISDN Test Set
Step 3
Put your TS350 into upgrade mode by holding down the C key and
then simultaneously pressing the
key to turn the TS350 on. You
will hear the turn on beep but initially the screen will be blank.
Note: Whilst upgrading there should be no network
connections to the TS350. Do not use the dc charger
during the upgrade process and make sure your
batteries are charged before starting.
Step 4
On your PC, in the Windows Start menu Run command dialogue
box, enter the path and filename of the Upgrade executable file e.g.
C:\Harris TS350\TS350Upgrade.exe
and follow the on screen instructions. If you are using a TS350
Upgrade CD you may run the TS350Upgrade.exe executable file
from your CDROM drive if you wish without copying the file to your
hard drive.
Step 5
When the upgrade download is complete, switch off your TS350 and
then turn it on again to load the new firmware. During the power on
screen sequence you will see the new firmware release number
displayed.
