DS33R11 Ethernet Mapper with Integrated T1/E1/J1 Transceiver
10 of 344
The integrated Ethernet Mapper is software compatible with the DS33Z11 Ethernet mapper. There are a few things
to note when porting a DS33Z11 application to this device:
• The SPI and hardware modes are not supported.
• RSER has been renamed to RSERI.
• RCLK has been renamed to RCLKI.
• TSER has been renamed to TSERO.
• TCLK has been renamed to TCLKE.
The integrated T1/E1/J1 transceiver is software compatible with the DS2155 T1/E1/J1 transceiver. There are a few
things to note when porting a DS2155 application to this device:
• The Facilities Data Link (FDL) support is available through software only. The TLINK, RLINK, TLCLK,
RLCLK pins are not available on the DS33R11.
• Multiplexed Microprocessor Bus mode is not supported on the DS33R11.
• The Extended System Information Bus (ESIB) is not supported on the DS33R11.
• The MODEC pins serve the function of the DS2155’s BTS pin.
• The interim LIU/Framer clock signals RCLKI, RCLKO have been renamed to RDCLKI, RDCLKO to avoid
confusion with the receive clock connections between the transceiver and the Ethernet mapper.
• The interim LIU/Framer clock signals TCLKI, TCLKO have been renamed to TDCLKI, TDCLKO to avoid
confusion with the receive clock connections between the transceiver and the Ethernet mapper.
• RSER has been renamed RSERO.
• RCLK has been renamed RCLKO.
• TSER has been renamed TSERI.
• TCLK has been renamed TCLKT.
