Up for auction is a lightly used TTC 42522 V.35 / RS-449 / X.21 DTE/DCE Interface Module use in 6000 and 4000 Fireberd Analyzer. Item is in near mint physical condition. I am unable to verify operational functionality at this time. V.35 / RS-449 / X.21 Interface Adaptor for Fireberd communication analyzers. The Combined Data Interface Module makes the FIREBERD a versatile, all-in-one data communications test instrument. Operating at rates up to 15 Mb/s, this interface module permits the FIREBERD to replace almost any V.35, RS-449, or X.21 device during out-of-service testing. The module also feature full support of the end-to-end and loopback testing, with V.54, and RS-449, remote and local loopback modes built-in. Add software-selectable DTE or DCE emulation, six different operating modes, and the FIREBERD's built-in RS-232 Interface, and you've got complete data communication testing in a single unit. Feature Summary: · Software-selectable DTE or DCE emulation enables convenient testing of network components. · Built-in remote and local loop codes for RS-449, and V.35 (V.54), allow easy sectionalization and testing from a single access point. · Built-in clock and data inversion detection and correction indentify and compensate for improper phasing between clock and data. · Complete flow-control troubleshooting, with usercontrollable signaling leads (CTS, TRS, DTR, and DSR), LED status indicators, and CTS-RTS delay measurement. · Round-trip delay accurately measures signal propagation time and verifies both component buffers and network design parameters. · Terminal Timing (TT) and Send Timing (ST) operating modes (RS-449 only) provide clocking source flexibility for all rates from 50 b/s to 15 Mb/s. · When used with the PDS-45 for protocol monitoring, the Combined Data Interface Module provides complete in-service and out-of-service data communications testing.
