MLS-3 and MLS-6 provide three or six low speed async/sync data channels, respectively, for the MAXcess-3000/3004. Data rates are soft-selectable from 9.6 bps (for FR, FR+, HDLC ) or 1.2 kbps (for async, transparent) up to 64 kbps. Each port can be set to a different channel speed. All ports have V.24/RS-232 interfaces. Each channel can be configured to one of three timing modes allowing support for most applications: – DCE mode, providing both transmit and receive clocks to the DTE – DTE mode, where both transmit and receive clock are accepted as input, allowing connection to a network All channels support prioritization and packet segmentation mechanism, for high-quality voice over Frame Relay.
Automatic self-test, buffer monitoring and alarm reporting is performed during power-up and normal operation. Each channel terminates with a 26-pin, high density female connector. The MLS-3 and MLS-6 modules support the following control signals to the adjacent DTE: RTS, CTS, DSR, DTR, DCD. The MLS-3 and MLS-6 modules are supported by RADview PC or HPOV SNMP management system.

MX-3000M-LS/* Three or six Channel Low Speed Data Module * Specify number of channels 3 for three ports 6 for six ports Adapter Cables All ports use a 26-pin, high-density, female connector. The following cables convert the 26-pin connector to 25-pin D-type and should be ordered separately. Cable length is 2 meters. CBL-SCS26/V24/*/+ * Specify configuration type DTE for connection to DTE device DCE for connection to DCE device + Specify connector type M for male connector F for female connector
APPLICATION
Note: when working in DTE mode, one of the following cables is required: CBL-MX/V24/CROSS/M CBL-MX/V24/CROSS/F
