Telos iPort High Density
iPort High Density
Telos iPort High Density is a networked multi-codec gateway that enables the transport of multiple channels
of stereo audio across any QoS-enabled IP network, including T1 and T3 connections and private WANs
with MPLS – perfect for large-scale distribution of audio to single or multiple locations.
iPort High Density is the workhorse of codecs, configurable with up to 64 bi-directional MPEG codecs.
Optionally, you can add aptX® encoding to any codec or use Linear PCM audio. iPort HD connects to Axia®
IP-Audio networks using a single ethernet cable for all I/O or can be used as a standalone multiple-stream
codec.
Coding algorithms include AAC, AAC-LD, HE-AAC (plus v2), MP2, MP3, optional aptX® Enhanced, or
Linear PCM. Bit rates range from 24 to 320 kbps for MPEG codecs, plus standard fixed rates for aptX, 24 bit
48k for Linear PCM. iPort High Density offers dual, parallel-path end-to-end streaming for ultra-reliability
and redundancy. Up to 20 unidirectional GPIO contact closures per codec are available in several modes to
allow considerable control flexibility. End-to-end GPIO is supported for each codec. An optional unique
Content Dealy feature allows independent local storage and scheduled delayed playout of any coded audio
channels.
Important - Content Delay requires additional installed hardware and a separate license for
activation. The base model iPort High Density does NOT include this hardware.

  • Page 14: Changing Passcodes

    Adjusting Leap Seconds From time to time, the leap seconds file needs to be updated. This is particularly important if your iPort uses the optional Content Delay feature where accurate playback time is needed. A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC), to accommodate the difference between precise time (as measured by atomic clocks) and imprecise observed solar time.

  • Page 26 Codec Receive Ports The base port numbers for both UDP and TCP determine the receive port number assigned to the corresponding function of the first codec channel. Port numbers for other codec channels are incremented by one per channel automatically. Note that if multiple WAN paths are used the A and B paths MUST have different base ports defined.
  • Page 27 Use the Encoder Type dropdown to select the method of MPEG encoding you wish to use. Along with several options for AAC, MP3 and MP2 encoding, you can also choose linear (uncompressed) audio or GPIO only. If the optional Enhanced aptX is licensed, you can choose options for Enhanced 16-bit and 24- bit encoding.
  • Page 28 Select the Protocol Type and specify an IP Address and Port for the receiver. Note the port used on the receiver is determined by the Global Options from the previous section. The Protocol type may be UDP, TCP, or multicast. There are tradeoffs in this choice that are only fully understood with knowledge of this aspect of IP networks.
  • Page 29 The Buffering drop-down box lets you choose how much buffer is applied to the received streams. A lower value gives a lower delay but depends upon the network to have low jitter. A range of values allows experimentation to find the optimum for your network conditions. One procedure is to try successively lower values until you hear audio interruptions.

We recommend you do some experimentation on your own before committing to an equipment purchase or broadcast of a major event. Does Zephyr iPort PLUS conform to the ITU N/ACIP specification? No, it does not.

    Using GPIO & Data with iPort High Density As multiple audio signals are encoded in iPort High Density and distributed over a WAN or other network, their associated GPIO information needs to travel with them. Zephyr iPort PLUS makes this happen by embedding GPIO events in the coded audio stream.

  • Page 34 Transit Point The Transit Point mode serves for forwarding GPIO events between a GPIO node connected on the local side of the Zephyr iPort PLUS, and the codec link. The transit point mode differs from the endpoint mode by the following: Zephyr iPort PLUS - encoder: On the hardware GPIO node connection it acts as a client, not server Zephyr iPort PLUS - decoder: The snake is not terminated in iPort, therefore GPI events received from the codec link are forwarded to client connections...

  • Page 35: Controller Emulation

    I/O Emulation In this mode, iPort emulates local presence of a physically remote I/O device, e.g. GPIO node. In brief, this mode is "symmetric" to the controller emulation mode in the following way: Use of console messages for command and response are swapped - encoder is listening to command and decoder is issuing response.

  • Page 37: Content Delay Configuration

    Content Delay is not a field-installable option. The factory must install it at the time you place your order. To verify that your iPort HD does indeed contain Content Delay, go to the License Management page. Feature licensing status is shown at the top of this page. Make sure that Content Delay is marked Active (not Inactive as shown in this example).
  • Page 38 Maximum expected bitrate per stream (kbps) The maximum expected bitrate per stream setting is used to calculate the total program storage time of the Content Delay feature based on the installed physical storage space. It shows maximum storage space, current free storage space, and currently configured storage time from all codecs. In this example, based on a stream rate of 192 kbps, there is a total storage time of 1044 hours, 30 minutes.

    The diagram above shows a simple set-up for streaming. A Livewire xNode AoIP interface provides live audio input, which connects directly to the Livewire Ethernet jack on the iPort. The iPort’s WAN jack connects to a network (typically the Internet via your router) that leads to a remotely located streaming server.
