    Located less than a mile from the Rock ‘n’ Roll Hall of Fame, there is always something interesting playing on the Telos test line. Let’s call Cleveland. If you prefer, you can call our test line in Europe. That number is listed under “Test Lines” on page iii at the front of this manual.

    3 The Details By now your Xport should be up and running. In this section, we assume you have gotten to know your Xport by going through the Quick Start procedure and brief tour covered in Section 2 (Getting Started). In this section, we'll explain more about how the mixer works, cover more about using the Auto Dial function, as well as how to use a cell phone for transmission when a telephone line is not available.

    HOT TIP! The Xport uses the center pins of the 6- position miniature modular (RJ- 11 style) jack. In parts of Europe, we have seen the same type of jack using different pins. In order to get the best performance from your Xport on POTS lines, be sure to set the COUNTRY menu selection for the correct setting.

    Reboot both units. They should now function normally. 3.7 Cell Phone Interfacing (the Aux Audio Interface) For maximum flexibility, your Zephyr Xport can be used as a mixer to establish connections through a cellular telephone (handset). The audio quality will be dependant on the type of cellular system used, and will be comparable to any other cellular call using the system in question.

  • Page 40: Frequently Asked Questions

    ZEPHYR 4 Frequently Asked Questions We cover general questions about the Xport and the technology involved here. If you have questions related to operational issues, or need to troubleshoot a problem, see Section 5 (What to do if…). Is Xport a “POTS codec”? Yes and no.
  • Page 41 ZEPHYR Is there anything I need to know about using ISDN for this application? Nothing special. The telephone network automatically translates the signals on the analog line to the digital form (called "G.711") carried over ISDN. The ISDN line must be configured to allow this type of call (called Circuit Switched Voice or "CSD").
  • Page 42 Because the Xstream has an Ethernet port, it may be upgraded over the Internet, without changing any parts or sending it to Telos. You may do so for free. Or, you may choose to upgrade by replacing a memory SIMM or by sending the unit to us. In these cases, there will be a modest charge.
  • Page 43 Omnia has been making a streaming audio dynamics processor for some time, which was designed in partnership with the Telos codec guys to sound good with coded audio. So it really was natural to get some of this Omnia work back into Telos products – hence the integration into Xport.

  • Page 44: What To Do If

    5 What to do if… Sadly, the world is not perfect. We all know this, but that knowledge does not help us when unexpected problems happen right before the "big broadcast". This section should help when things won't work. When dialing using POTS the status goes to “off hook” and then immediately back to “on hook”. What should I do? Check the following: Is this really an analog phone line? If it was connected to a phone with more than two lines, or had...
  • Page 45 active line present). When using POTS you can speed boot time by pressing <5> and <6> simultaneously when the "Found ISDN card" message is displayed. I can’t find the ISDN setup menu. The ISDN circuit should be connected to the Xport before you power the unit up, or it will boot into POTS mode.
  • Page 46 In this case use the <#> or <*> key to enter the <,> character (pause) when dialing. Can the Xstream and Xport in question call the Telos Test line? I can’t place a call using ISDN in Zephyr mode.
  • Page 47 When placing ISDN “Zephyr mode” calls between Xstream and my Xport, I get no audio or lock. Zephyr mode calls from Xport require that the Xstream’s codec settings be configured as follows: Xmt = AAC-LD mono 64; Rcv = AAC-LD 64; Bit rate 56 or 64; Sample = 48 kHz I can’t place or receive calls using ISDN.
