Teradyne, Inc. (NYSE: TER) Broadband Test Division today announced that Cesky Telecom has placed an expansion order for its 4TEL II(R) Voice Customer Care Test System. The contract covers deployment of 4TEL II Software and LDU 100 (Loop Diagnostic Units) hardware to monitor and test telephone lines operated by Cesky Telecom in the Prague region.
