2.7 Transmit System Bus
The Transmit System Bus (TSB) consists of a timebase, slip buffer, signaling
buffer, and transmit framer
between the XMTR and system bus. The system bus is compatible with the Mitel
ST-Bus, the PEB Bus, and the AT&T CHI Bus. TSB directly interfaces to other
Conexant devices with no need for external circuitry.
(TSBCKI), Transmit PCM Data (TPCMI), Transmit Signaling Data (TSIGI),
Transmit Frame Sync (TFSYNC), Transmit Multiframe Sync (TMSYNC), and
Transmit time slot Indicator (TINDO). See
