The ATM Forum has claimed that ATM technology provides the only environment to successfully deliver both voice and data over single VPNs (Virtual Private Networks).
The statement comes near the completion of the group's Voice Trunking Over ATM (VTOA) specification, which is due at the end of July.
Andy Bray, chairman of the Forum's awareness committee, argued: "There is no reason why a single VPN infrastructure shouldn't cover both voice and data but ATM is the only thing which could facilitate this."
He believes that converged VPNs would allow network managers to ask themselves whether they need to bother building their own networks.
"Carriers and users are keen to consolidate their voice and data networks.
But there is a huge amount of voice traffic which needs to be handled," Bray said.
The ATM Forum expects to complete its Private Network-to-Network Interface V1.0 for the interworking specification in September. It hopes to finish its work on 2.5Gb ATM by the end of 1998 and is already working on the 10Gb specification.
Bray said the increasing number of recruits to the ATM Forum reflects a huge switch in demand from traditional voice data integration systems like TDM to higher speed multi-service technologies.
