The SRU card also supports X.50 division 3, an ITU (CCITT) standard for sub-rate multiplexing. The
maximum bandwidth of the SRU card is 115.2Kbps. The SRU card provides the ability for software
configurable delay optimization. If delay optimization is used on all 10 ports, the maximum bandwidth
available will be 76.8Kbps. Software-initiated diagnostics supported on the SRU card is the same as on the
HSU card. Table 15 describes the SRU card specifications.
