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

TM

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

®


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 U-

TE mode this protocol is the TS350 to Network protocol; in ISDN S-

Monitor 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

®


•

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

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

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.

This mode allows the transmit and receive directions to be independently tested for errors end to end. In this mode the TS350 may be left unattended.

After The TS350 auto answers the call you are presented with the test results screen, which shows the errors, received in the incoming test pattern from the remote tester.

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:

Baud rate 115200

Data bits:

Parity:

8 none

Stop bits: 1


68

TS350

®


Step 3

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.
