2001-00076-000 ZEPHYR XSTREAM RM ISDN DIGITAL AUDIO TRANSCEIVER

Zephyr Xstream is a full-featured ISDN transceiver with high-fidelity MPEG-2 AAC and low delay MPEG4 AAC-LD coding, along with standard Layer 3, Layer 2 and G.722. It includes AES/EBU I/O and features full duplex stereo operation of up to 20kHz audio on a single ISDN line; broadcast quality mono audio at 15kHz or 20kHz is possible on a single ISDN “B” channel or other 56/64 kbps channel. Includes built-in ISDN Terminal Adapter for worldwide use. There’s also an Ethernet port for remote control and IP audio streaming.


Technical Details

General 

  • Full duplex, high-fidelity codec using MPEG-2 AAC, MPEG-4 AAC-LD MPEG-2 Layer-3, MPEG-2 Layer-2, AACPlus, and G.722; fully compliant with international standards.

 

Frequency Response 

  • 20 - 20kHz @ 48kHz fs (+0/-1dB, swept sine tone procedure)
  • AAC all modes except Stereo 64: 20-19,800Hz at 48kHz fs., 20-15,000Hz at 32kHz fs.
  • AAC Stereo 64: 20-10,000Hz at 48kHz fs., 20-7,000Hz at 32kHz fs
  • AACPlus mono (for use reception from the Xport): 20-15,000 Hz 48kHz fs
  • Layer 3 all modes: 20-16,000Hz at 48kHz fs., 20-15,000Hz at 32kHz fs
  • Layer 2 mono, dual mono: 20-7.8kHz/9.8kHz
  • Layer 2 mono 20-8.6 kHz at 24 kHz fs.
  • Layer 2 joint stereo: 20-20,000Hz at 48kHz fs. 20-15 kHz at 32kHz fs
  • G.722: 20-7,500Hz.

 

THD+N

  • Audio loopback, 48kHz fs, analog I/O, input at 1kHz +20dBu: 0.004%

 

Dynamic Range 

  • A Weighting, AAC, Layer-3 or 2 end-to-end: 101dB typical

 

Send Input

  • Active balanced with RF protection.

  

Zephyr Xstream:

  • LINE: Settable to -11 or +4dBu (or -15 to 0 dBu) nominal level
  • Clip point: 18 dB above chosen nominal level.
  • Impedance: > 10K Ohms (x2)
  • Connector: XLR female/quarter-inch TRS combo connector.

 

Zephyr Xstream MX and MXP:

  • Clip point: 15 dB above chosen nominal level.
  • Impedance: Line > 10K Ohms (x2)
  • Connector: XLR female/quarter-inch TRS combo connector.

 

Limiter

Zephyr Xstream MXP

  • Internal DSP-based AGC/limiter with Omnia® audio processing. Includes presets for music & voice, selectable per channel.

 

Zephyr Xstream

  • Analog soft-clipper prevents A/D converter overload without loss of dynamic range

 

Line Bit Rates (ISDN)

Receive Output

  • Active differential.
  • Level: Front panel selectable for -10 or +4dBu, nominal.
  • Impedance: < 33 Ohms (x2)
  • XLR male

 

AES/EBU Digital I/O (rackmount version only)

  • Sample rates supported: 32, 44.1 and 48kHz
  • Rate conversion: Input and output independently selectable. Can be bypassed.
  • Input clock: From external source or Telco clock.
  • Output clock: From transmission sample rate, external source, or AES/EBU input.

 

Inverse Multiplex/Demultiplex

Internal channel splitting/combining of two network channels for stereo modes.

  • AAC: Telos Zephyr™ protocol.
  • AAC-LD: Telos Zephyr™ protocol.
  • Layer-3: FHG/Telos Zephyr™ (Buchta) protocol.
  • Layer-2: CCS CDQ™ protocol compatible.

 

Optional V.35/X.21 Direct Digital Interface

  • Two ports, both V.35/X.21. Automatically selected when the appropriate cable is connected.

 

ISDN Interface

  • Compatible with National ISDN, AT&T 5ESS custom, Northern Telecom DMS-100 custom, Siemens EWSD, INS 64(Japan) and EURO-ISDN (ETS-300). Compatibility and approval pending in some countries; contact Telos for current status.

 

LAN Interface
