MODMER / TTMER18

The ATM measuring equipment (HP 75000 (BSTS-Broadband Series Test System))

ATM measuring equipment is a measuring set with a modular build-up, which can be configured flexibly. Considering its function, it is an alloy of an interface tester and a protocol analyzer. A picture about this measuring equipment:

Build-up of the measuring equipment

Functional units of the measuring tool are located on cards, that can be plugged into a framework of 19 inches with 11 expanding places. Connection of cards can happen with the multiprocessor bus system of VXI (VMEbus eXtended Interface).
Cards plugged into the framework from left to right:

A controller computer with a handling program based on UNIX, X-Window
Background storage of the controller computer
Two sets of signal generator/receiver and measuring interface, which allow the tests between point and point. In details:
- Two E4209B typed Cell Protocoll Processors (CPP), as signal generator and receiver (generation and reception of ATM cells)
- Two E1697 typed 155 Mb/s (STM-1) optical measuring interface
- Two E1619B typed 25.6 Mb/s ATM (4B/5B) measuring interface
- Ethernet interface

Available softwares:

Operation system: Unix realization of HP firm, with a graphic surface based on X Window.

_{Remote control: tester can be used even from an optional X client (Linux, AIX (e.g.. mars.ttt.bme.hu), or an X emulator with MS Windows). In case of Linux, and AIX we can get the screen of the tool with writing in the X -query bbseries.ttt.bme.hu command.}

E4214B type UNI Signalling Test Software
E7830A type UNI 3.1 ATM Layer Conformance for Intermediate Systems

Handling guide

Switching on
Wait after switching oin, while the initialization of the operation system will be running, and the log in menu will appear.
Use the user name ttmer18 for entering, password will also be ttmer18.
Then will appear handling surface of the tool (HP-VUE)
Use the EXIT icon for switching off!
Usage of the HP-VUE surface in a few word:
- 6 virtual screens (1-6 buttons on the bottom of the screen)
- We can reach the terminal window by clicking to the small computer image on the left lower part of the tray
- By clicking to the arrow over the icons of the tray, we will see a subsequent row of icons.
Figure 1. demonstrates the state we will get, if we click to the arrow over the icon of the measuring tool:

Start the Test Sessions (configurating the tester) program (Figure 1. icon can be found above right), click to the icon only ONCE! Attention: program can be started quite slowly (initializatin of HW takes 1-2 minutes), please, wait patiently!
Considering to the block diagram of the interface tester, interface cards of 155 and 25.6 Mbit/s are suitable for the measuring interfaces.
CPP (Cell Processor) cards provide the function of signal generator and receiver. First configuration task will be to accord them.
In case of using the line interface card of 25.6 Mb/s we can make the process, as follows:
- o Click to the icon of the CPP card in the 3. slot, and to the line interface in the 5. one (Figure 2.) Then the ATM and the 4B/5B box above will be connected to each other, too. (Even generally: we will assign the CPP card to the interface card from right to it!)
  Figure 2: Test Sessions program
- As a closure of the connection, press the Start Appl. button! (ATTENTION: it is very slow!!! The firmware downloading to the measuring card takes 1-2 minutes!)
- Implicitly, we must do the same in case of the 6. and 8. slot. Before we do it, click to the Unused Ports on the left!
- Assignment is done. We have to set now the interface cards. Click to the Module Selection/Slot 5: compare the figure with the general block diagram of the protocol tester!
  - Transmitter: on.
  - Configure Interface
    - Receiver and Transmitter: UNI
    - Test Function: bidirectional
    - Header error correction ON
    - Fill cells: IDLE
    - Clock: internal
- Slot 8 - do the same
Zoom the program out to an icon!

We have finished the previous unique measuring card levelled sets required by the conformance test software (ETS) useable during the measurement, and generated two PCOs.

Handling guide/Test manager

Hereinafter we will get one level higher in the hierarchy of tool control: we will set the effective testing software (ETS), which has not dealed already with that e.g. on what physical interface would the testing be happened.

Start the Test Manager (Figure 1), clicking to the icon only ONCE (Attention! It is slow!!!)
Study its usage, it is quite trivial (Figure 3):
Figure 3: Test Manager
Loading the set of tests: File menu/New Template menu points (UNI 3.1 ATM Layer Conformance for Intermediate Systems)
Setting of PICS, PIXIT, OTHER parameters: "Configure" menu. Attention, several pages may belong to one category!
We can save the set of test together with the running results, and we can load it back later.
Selection of test cases: Select menu, or click to the small square after the test series one by one.
After running the test TTCN results can be enlargened in a separated window, clicking to the "Pop Traces" button.
Test report to the report file: Results/Detailed Report
Copying the report to a PC:
- command prompt
- cd destination directory
- c: ftp bbseries (login, password)
- bin
- cd source/home/ttmer18/testmanager
- get filename
- quit
