DS31256 and T1/E1 Interface As the DS31256 uses receive free queue entries to write received packet data to host memory it creates entries in the Rx done queue. These Rx done queue entries inform the host about the location and status of received data. Refer to the DS31256 data sheet for more detailed information. Examples of DS31256 Applicatio-Abstract: App Note 3345 provides application examples for the DS31256 HDLC Controller. OverviewDS31256 has 256 independent directional HDLC channels, which support up to 64 T1 or E1 data streams. This application note highlights the definition and functionality of the DS31256 loopback modes. These loopback modes can be used in channelized and unchannelized modes, depending on which mode has been configured for a given port. (Refer to Section 6 of the DS31256 data sheet.) This application note does not cover the DS31256 configuration ...

The errata listed below describe situations where DS31256 revision B2 components perform differently than expected or differently than described in the data sheet. Dallas Semiconductor intends to correct these errata in subsequent die revisions. This errata sheet only applies to DS31256 revision B2 components. Order MB90F462A at componentstransistors.com.
