Abstract: A net-aware telephone switch enabling a user to receive or send calls from/to both the Internet and the PSTN comprises a two-line switch connecting with the communication terminal for switching the outgoing call between IP call mode and PSTN call mode; a CPU, operated for sending out an IP call and receiving an IP call to/from the outside; a storage, for storing programs and data required for sending out or receiving the IP call; a connector for connecting the net-aware telephone switch with the Internet; and a bus for connecting all the above components with each other and for transferring data among them.

Abstract: Water soluble air controlling agents can be admixed with dispersant for cementitious compositions to provide an admixture for cementitious compositions that is stable over time. The water soluble air controlling agents are compatible with water based dispersants. Suitable water soluble air controlling agents include alkoxylated polymers. A cementitious composition is provided that includes cement, water, a dispersant for cementitious compositions, and a water soluble air controlling agent. A method is provided for making a cementitious composition that includes mixing cement, water, a dispersant for cementitious compositions, and a water soluble air controlling agent.
