CX28560 Data Sheet
The CX28560 supports four serial port modes: Conventional Channelized, Conventional Unchannelized, Conventional T1, and
TSBUS. In TSBUS mode, the CX28560 supports a special Mindspeed proprietary interface: the TSBUS (Time Slot BUS). The
TSBUS allows for mapping of all tributary signals to time slots for a transmission to external devices, such as Mindspeed’s BAM
(Broadband Access Multiplexer) device family. The TSBUS interface consists of two serial interfaces: a 51.84 MHz payload
interface and a 12.96 MHz overhead interface. Payload of tributary signals is mapped to time slots on the payload bus allowing
for a transmission of the following signals’ payload:
Overhead information including SONET/SDH/PDH overhead and control information is transmitted in time slots on the overhead
TS-Bus interface. The first 12 ports of the CX28560, when configured in TSBUS mode, also support DS0 extraction.
