Adtech Spirent SX/13 DataLink Channel Simulator with T1 Adtech Spirent SX/13 Data Channel Simulator Spirent SX Data Link Simulators The Spirent SX Data Link Simulators create the same delay and error characteristics caused by long distance terrestrial and satellite data links. By providing very realistic simulations of actual network conditions, they allow engineers to stress test new equipment and network applications under repeatable and controllable conditions. Utilizing dual-channel, full-duplex operation, these simulators provide bi-directional testing with programmable delays, random bit errors and burst errors. Multiple delay and error events can be programmed into complex sequences to simulate a wide variety of chronic and periodic conditions or events such as peak traffic times and equipment overloads. Typical simulator applications include testing the operation, performance and reliability of multiplexers, bridges, encrypters, network applications and other communications hardware and software. When used for link simulation, these simulators physically connect directly between two pieces of equipment to replace conventional data links such as satellite connections, WANs or telephone networks. They can also be used in line with a real data link to add additional delays or errors or to simulate the effects of adding an additional link to the system. Full-Duplex Operation Each simulator has two separate channels to simulate the bi-directional characteristics of a full-duplex data link.Each channel operates independently and has both transmit and receive functions. The SX/13 model also permit different delay and error settings for each direction of the full-duplex data stream. Bypass and loopback modes can be selected whenever standard bi-directional flow is not required. Delay Generation Each channel uses a variable length first-in-first-out delay buffer with user-selectable delay and data rate parameters. These parameters set the length of this buffer which in turn determines the amount of time it takes data to pass through each channel. The maximum delay length depends on the data rate (lower data rates permit longer maximum delays). At the lower rates, delays up to 9,999 ms (just under 10 seconds) are possible. Delays can be specified in milliseconds or bits depending on the measurement requirements of the test. Error Generation Each channel has a and a The Random Error Generator simulates background errors caused by Gaussian noise and is active during gaps between error bursts. Random error rates can range from 1 x 10-9 to 1 error per bit for the SX/12 models or from 1 x 10-12 to 1 error per bit for the SX/13. The Random Error Generator normally injects logical errors. However, the SX/13 can also be set to inject BPVs (Bipolar Violations) when bipolar interfaces such as DS1 are used. Includes SX/13 T1 Interface Card.

Return Shipping: The customer is responsible for all return shipping charges. SHIPPING: PLEASE NOTE: All shipping rates are calculated based on an estimation of the items packed weight. We will always make our best effort to adjust this rate once we know where the item is being shipped, and your invoice will reflect this. If for any reason you feel that the rates are higher than they should be, please feel free to contact us, and we would be more than happy to re-assess the charges. Additionally, if you purchase several items, eBay's combined shipping calculator rarely produces an accurate estimation of combined shipping weight, so please contact us and we will make any necessary corrections. SHIPPING DETAILS: All items will be securely packaged or palletized. Most items will be shipped within 1 business day. For items that require freight shipping, please allow up to two days for an invoice. All tracking information will be forwarded to the email address associated with your PayPal or eBay account. DOMESTIC SHIPPING: A contact name, phone number and company name are required for shipping purposes; items may not ship unless this is provided. In the event that the bidder/buyer would like to handle the shipping arrangements, please provide us with your FEDEX or UPS account number. Please Note: There will be a $4 pick-up fee charged for FedEx shipping. INTERNATIONAL SHIPPING: Please allow a 24 hour response time due to time difference. A contact name, phone number and company name are required for shipping purposes; items may not ship unless this is provided. In the event that you have questions about shipping logistics please contact us at (408)743-5609 before purchasing. International orders may be subject to Duties, Taxes or other Import Fees. The bidder/buyer is solely responsible for these fees, documents and transportation if held at a customs office in the destination country. FREIGHT: We will handle all of the preparations for freight shipments, ie: palletizing, shrink wrapping, etc. If you purchase an item that requires freight shipping, please allow two days to receive an updated invoice.
