Data Sheet DXC Module D8HS 8-Channel High-Speed Data Module • Eight high-speed data channels • RS-442, RS-232, V.35, or X.21 serial interfaces on any channel • Programmable data rates: 56 to 1536 kbps for T1 and 64 to 2048 kbps for E1 • User-assigned or automatically selected timeslots on the E1 or T1 links • Cross-connects timeslots with any other DXC-8R/10A/30/30E module Each D8HS module provides the DXC Local support is provided for four control chassis with eight high-speed data signals for each channel. channels. Powerful testing capabilities and The module is supported by DXC systems self-diagnostics upon power-up reduce with DCL.3 common logic, from version downtime to a minimum. 9.0 and onwards. D8HS is supplied with a 200-pin Each synchronous data channel supports high-density connector. To convert to the data rates of n × 56 or n × 64 kbps following interfaces, splitter cables are (where n = 1 to 24 for T1 and 1 to 32 for available from RAD (see Ordering): E1 links).
