Dual Network Support - 10Base-T and Token Ring
Figure 11 shows the LXT901A/907A Transceiver with a Texas Instruments 380C26
CommProcessor. The 380C26 is compatible with Mode 4 (MD0 and MD1 both High). When used
with the 380C26, both the LXT901A/907A Transceiver and a TMS38054 Token Ring transceiver
can be tied to a single RJ-45, allowing dual network support from a single connector. The
LXT901A/907A Transceiver AUI port is not used. The DSQE pin on the LXT907A Transceiver is
tied Low and the STP pin on the LXT901A Transceiver is tied High.
