822560

Special ten port low delay sub rate unit (LD-SRU) with RJ-48 modular connectors. Connects to the A, B, C and D buses. Supports synchronous and/or asynchronous data ports from 300 bps to 38.4Kbs. Supports DS0-A, DS0-B, V.14 and X.50 division 32 subrate multiplexing formats by hardware instead software as in the 822060 SRU. The configuration is controlled via local terminal or remote NMS. The SRU offers lower delay, increasing throughput: Maximum of 3 ms +/- 10% end to end of rates 9.6 kbps or higher for sync. Maximum of 6 ms +/- 10% end to end of rates 9.6 kbps or higher for sync. SRU card ports can also be multiplexed with voice traffic on an ADPCM card (up to 19.2 Kbps data circuit in 24 Kbps data circuit in 24 Kbps ADPCM channel). Supports CSU, DSU and CPU loopbacks. Requires v5.3, v3.9 or higher CPU firmware. Limited Availability. Will be replaced by the 822570.
