U.S. network equipment maker Cisco Systems Inc expects to continue on the acquisition trail after last week's agreed $3 billion offer for Norwegian videoconferencing company Tandberg.

You are going to see acquisitions in this industry heating up, chief executive John Chambers said on Monday, adding Cisco would likely be involved.

Last week, Cisco struck a deal to buy Tandberg to dominate the fast-growing market of corporate video communications.

The companies do not expect to see big regulatory hurdles for the deal. There is almost no product overlap, Chambers told journalists on sidelines of a telecoms industry conference.

Chambers said Cisco would make more acquisitions outside United States after Tandberg. It won't be the last, he said.
