Networking giant Cisco has elaborated its strategy on the integration of voice, data and video.
At the Networld Interop show in Paris earlier this week, the company introduced a voice-over-IP module for the 3600 series by the end of this year.
And, according to Phil Dean, marketing manager of the product area at Cisco UK, the move is the first phase of its entry into the voice telephony market.
He said: ?IP was never designed to carry real time data like voice but there are now controls to offer the delay transmission that?s needed.?
He said the other phases in Cisco?s plans will include more emphasis on the service provider market and promised further server products.
?The 3600 Series does not scale up to the PSTN level,? he said. ?But I would imagine that we will see a server which will be able to do that.?
Cisco, he said, is taking a triple approach to the telephony market and voice over IP is just one set of its product offerings. It will also produce solutions for both Frame Relay and ATM, he said.
The voice network module on the Cisco 3600 will support up to two voice interface cards in three different types. Each has two ports but have differing interfaces for connecting to different equipment.
They are the Foreign Exchange Office (FXO), for connection to PSTNs; the Foreign Exchange Station (FXS) to connect to ordinary phones, fax machines, key sets and PBXs; and the Ear and Mouth (E&M) interface for PBX trunk lines.
Dean said that while voice telephony on the Internet was still not of very great quality, there were few obstacles to using it for fax systems, with great cash savings for companies.
