- Description
- This Amendment is issued to answer questions in response to Combined Synopsis/Solicitation N00421-06-T-0083. QUESTIONS & ANSWERS: QUESTION 1. Section 1: There are three specified operating sites (USN Ships, USCG ships and USN/USCG shore installations). Are DVLCE?s utilized in shore applications and DVLRS? in shipboard applications? Are there any other site options that we should anticipate? If so, which system configuration is needed for the additional sites RESPONSE: The DVLRS is intended for Navy shipboard applications only. The DVLCE is suitable for USCG Shore and Cutter applications. We know of no other site options. QUESTION 2. Section 3.1.1.1.e, 3.1.1.2.b, 3.1.1.4.b: Does this mean that up to four analog audio signals mixed into one audio output feed playing synchronously with the video (if the video option is installed and part of the specific replay scenario)? RESPONSE: Yes. A real-time playback scenario would include up to four combined (summed) audio circuits and a video output for the reconstruction of events for review or training purposes. QUESTION 3. Section 3.1.3.10: Is the IRIG-E generated output requirement a DC level shift or modulated signal RESPONSE: It is a modulated 100 Hz carrier with a signal frame rate of 10 seconds and a resolution of 10ms. QUESTION 4. Section 3.2: The DVLRS appears to have additional space available for system components. Can the DVLCE physical dimensions be exceeded as long it fits into the DVLRS cabinet and the DVLRS cabinet dimensions are conformed to? RESPONSE: The dimensions of the DVLCE must be in accordance with SOW paragraph 3.2 in order to retain compatibility with USCG shore facility and Cutter applications. QUESTION 5. Sections 3.2.1.d, 3.2.2.1.a and 3.2.2.2.a: Serial ATA is accepted as a robust, fast and reliable data bus. Its performance is designed to compete with the various SCSI adaptations. You have accepted Serial ATA as a bus interface for the DVD-RAM drives. Is it acceptable in the RAID-1 hard drive arrays? RESPONSE. No. Per SOW sections 3.2.1.d, 3.2.2.1.a and 3.2.2.2.a, the hard disk interface for the System drive array and the Wrap Around drive array shall be SCSI Ultra 320 or Serial Attached SCSI. QUESTION 6. Section 3.2.1.f: Please identify under what conditions, and in what operating sites, the DVLCE will operate in a stand-alone mode. RESPONSE: At this time, the USCG shore communications facilities and Cutters. QUESTION 7. Section 3.2.2.3.j.1: We provide the user with a selectable update to the DVD-RAM archiving drives. In our reliability testing over the years, we have found that buffering the data and then updating the DVD-RAM drives increases MTBF of the physical drives, thus reducing maintenance costs. Is this acceptable? RESPONSE: Per 3.2.2.3.j.1 and 3.2.2.3.j.2, the DVLCE shall be software user-configurable to: (1) Buffer a user selectable timeframe (per 3.2.2.3.j.2) to the Wrap-Around Drive, then record to the active archive drive?or (2) Record directly to the media with out buffering (3.2.2.3.j.1). QUESTION 8. Section 3.2.5.3: Under software control and configuration, we can identify two adjacent input channels as transmit and receive audio pairs, sum and record them to single channel (example: sum channels 1 & 2 and store the combined signal on channel 1). Is this an acceptable implementation for the SOW specification? If not, please explain how the DVLRS cabinet wiring, between the REAR INPUT/OUTPUT PANEL and the DVLCE is modified when 4 to 2 wire converters are required. Please clarify your requirement of up to four selectable channels. Is this four audio inputs combined to form two recording channels or eight audio inputs combined to form four recording inputs? RESPONSE 1 of 2: Per SOW paragraph 3.2.5.3, it is an acceptable implementation. RESPONSE 2 of 2: Per SOW paragraph 3.2.5.3, the DVLCE shall have the capability to sum/combine eight analog inputs into four DVLCE channels. Example: With shipboard high frequency radio systems, a typical full-duplex ?Harbor Control? audio circuit consists of a separate receiver and transmitter, hence two separate audio pairs per full-duplex circuit. The DVLCE shall be capable of summing/combining eight pairs from such circuits as ?Harbor Control? into four of its input channels. QUESTION 9. Section 3.2.10.1: Can the LCD / touch screen be located on the panel directly below the DVLCE, as long as the DVLRS dimension requirements are maintained and be a separate LCD display / touch screen in stand alone DVLCE installations? RESPONSE: Per SOW 3.2.11.1, the display must be an integral part of the DVLCE front panel. QUESTION 10. Section 3.13: FSK and RS-422 inputs/outputs are options. Are they mutually exclusive or will there be instances when both may be ordered as part of one DVLRS or DVLCE system? RESPONSE: A shipboard DVLRS would be configured for one or the other interface, not both. QUESTION 11. Section 3.13.1.1: A. For the FSK input, what is the bit rate per second that the various tones will appear at the input? B. What is the needed bit rate per second that the various tones need to appear at the FSK output? C. What is the FSK output impedance specification requirement? RESPONSE A: FSK communications is a navy target message format. The Slow FSK message is an 88 bit serial message consisting of a sync pulse (2.4KHz) followed by ones (9.6KHz) and zeros (4.8KHz). The Fast FSK message is also an 88 bit serial message consisting of a sync pulse (12KHz) followed by ones (48KHz) and zeros (24KHz). Both FSK data rates operate at 0 Vdc and 5.0 Vdc logic levels. RESPONSE B: The FSK type at the output connector will be that of the archive being replayed, therefore its output could be fast or slow FSK. RESPONSE C: The FSK output must drive a 50 Ohm load. QUESTION 12. In order to properly gauge the amount of information submitted, with respect to the content/format for this solicitation, is a point-by-point compliance matrix to the SOW required, or simply a response with a general statement of compliance and including generic technical data all that is required RESPONSE: A response with a general statement of compliance is required.
