Frank,
Sorry. The article you posted was WAY over my head! Maybe it's something DenverTechie can comment on.

But here's some other interesting news from Cisco. The interesting parts are in bold. This switching business is getting complicated. Now there is a switch that can be both circuit AND packet switched? I didn't understand the comment but it appears to say this?

Cisco Systems to Acquire Summa Four Inc. Extends Advanced Voice Services to IP Environment

SAN JOSE, Calif.--(BUSINESS WIRE)--July 28, 1998--Cisco Systems (NASDAQ:CSCO - news) Inc. today announced it has signed a definitive agreement to acquire publicly-held Summa Four Inc.of Manchester, N.H. Summa Four is a leading provider of programmable switches. Based upon Cisco's July 27, 1998 closing price of $97.50, the stock exchanged would have a value of approximately $116 million.

Cisco Extends Voice Services to Packet-Based Networks

Summa Four's open standards-based programmable switches will enable Cisco to offer value-added telephony applications to new and existing service providers as well as extending these services to a voice-over-IP (Internet Protocol) infrastructure.

These switches are used today by service providers for basic call switching as well as delivering value-added services such as voice mail, calling card and voice-activated dialing. This acquisition reaffirms Cisco's strategy to provide an open services environment enabling applications for circuit- and packet-switched networks.

Cisco intends to expand Summa Four's existing relationships with application developers and will help them to extend their service platforms to voice-over-IP networks. Carriers will select from more than 50 market-leading application developers who have built a broad array of voice solutions based on Summa Four's switching family.

Summa Four was founded in 1976. The 210 employees led by Summa Four president and CEO, Robert Degan, will become part of Cisco's Network-to-User Business Unit headed by vice president and general manager Kevin Kennedy within Cisco's Service Provider line of business.

Preserve the visibility of the 64 kbps DS0? <grin>

Frank-
Is this not a smart move to preserve the value of the existing base of voice circuit switching?
After all this is the common atom of the circuit switching molecules and there is a ton of it around. And it works pretty well. The only real gripe is the relative cost/bit.
Best wishes,
Dan
