Switch Family Advances The Convergence Of Voice And Data Networks

Targeting the convergence of voice and data networks, the company's new familiy of time slot interchange(TSI) digital switches is offered as having the widest range of price and switch-capacity options in the industry. To serve the needs of the packet networking market, these switches are offered in capacity ranges from 128 x 128 to 4K x 4K, with expansions beyond 4K x 4K expected by the end of this year.
These switches are based on traditional time-division multiplexed (TDM) interface standards. They are capable of maintaining an interface with traditional telephony-based standards while providing the ability to switch and route digital telephony signals during the transfer of voice information. Features include PCM protocol support (ST-Bus/GCI), buffered data modes, a simple microprocessor interface and control, a JTAG port on most models, and 3.3-V operation. The devices are currently sampling in 128 x 128 to 4K x 4K capacities, with production quantities available in 128 x 128 and 256 x 256.
