TTC 42522

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 flexibili
