Page 8: Introduction
Introduction Congratulations on your purchase of the Telos Z/IP ONE! This codec achieves a new level in IP Audio transmission at a very attractive price. It is a one RU unit intended to be used with a microphone directly, or an external mixer for remote broadcasts, or anywhere space is at a premium. -
Page 10: Quick Start Guide
2.1 Unpack and Identify Your Z/IP ONE is shipped with a few accessories that we won’t use for this initial setup, but you may want to use later. For now, we’ll want the Z/IP ONE itself, AC power cord, and a network cable – all included with the Z/IP ONE. -
Page 11: The Zip/One User Interface
Z/IP ONEs with software earlier than v2.0.0r, such as the one shown above, had the version number printed on the main screen instead. If your Z/IP ONE is not running at least v2.0.0r, please update your codec to the latest released version of software. - Page 12 Within a few seconds, the ZIP light should come on, too. The ZIP indicator is your assurance that your Z/IP ONE is communicating with the Telos ZIP Server, and that connections to other Z/IP ONEs and Zephyr/IPs are just two button presses away.

Page 15: Codec Features
| Section 2 …Now what? Most hardware codecs, such as the Telos Z/IP ONE, Telos ProSTREAM, and Telos iPort, offer a choice of audio coding algorithms. With unhelpful names like “G.722”, “AAC-LD”, and “Layer 2”, how does one choose the best coding algorithm for a given connection or use? A full discussion of audio coding is in Appendix B, Audio Coding Reference, but the following tables summarize their features at a glance. -

3.1 Rack Mounting the Studio Unit The Z/IP ONE mounts in a 1RU space in a standard 19” rack. The Z/IP ONE does not have an internal fan, and does not have any special requirements for space above and below the unit. As long as you keep the stirred air in the rack between 0 and 40 Celsius (32 to 104 degrees Fahrenheit) with a relative humidity of 0 to 98% (non-condensing), the unit will operate as described. -

When using Livewire + failover, the Z/IP ONE will prefer Livewire audio if it is available. If it is not, for whatever reason, the Z/IP ONE will use the AES/EBU input for its transmit audio. If the AES/EBU stream is unavailable, it will use the Analog inputs. -
Page 27: Input Mode
5.6 AES/EBU Output Sample Rate Use the AES/EBU Output setting to select the sample rate of the AES/EBU audio output by the Z/IP ONE. You can select between 48 kHz, 44.1 kHz, 32 kHz, and Sync to AES-Input. All of the fixed sample rate settings are relative to the Z/IP ONE’s internal sample clock. -

80. Since the standard port (and the unofficial, but relatively common management ports of 8800 and 8080) are well known, a Z/IP ONE on the public internet should have its web server set to a unique, non-standard port. - Page 32 You may preview the codec again after a reboot.The aptX Enhanced codec is available as an optional software license. To use aptX, each Z/IP ONE must have a license to use the codec. If you would like to evaluate the codec before purchasing it, a demonstration mode is available.

You may also enter the activation key via the Software web page. If your Z/IP ONE is on a private network, this is the method that you must use. When you enter the key on the web page, if the Z/IP ONE is unable to activate the key on the license server, you will be given a link to activate the key yourself. -

Device Visibility – Choose whether the Z/IP ONE is visible to everyone in the directory, only people in ♦ the same group, or no one at all. A ‘hidden’ Z/IP ONE can still be dialed by anyone who knows its name and group, but will not show up in any directory listings. -
Page 35: Parallel Port
The Setup->Parallel Port submenu shows the settings and current state of the input and output General Purpose I/O (GPIO) pins. These pins may be either on the physical parallel port on the back of the Z/IP ONE, or virtual pins on Livewire GPIO. Output status bits are always reflected both on the physical and virtual ports, but you must configure which of these two sources is used for the input bits. -
Page 36: The Status Screens
The Status Screens The Z/IP ONE has seven screens of information reporting the current state of different systems in the codec. You can reach these displays from the main menu by either selecting the Status item or pressing the ESC key on the keypad. A status screen will also be shown when there is no user activity on the front panel interface. -

- Page 46 Presence Service Once your Z/IP ONE is registered with the server, it checks in periodically to make sure that the server knows about any IP address or other network changes that may have happened. Because of this, the server can keep track of which Zephyr/IPs are currently online.
-
Page 47: N/Acip Session Initiation Protocol
Session Initiation Protocol, or SIP. SIP is a signaling protocol widely used for Voice Over IP (VoIP) applications. Using SIP, the Z/IP ONE is able to accept and make calls to a variety of devices, including some VoIP phones. SIP can be used in two modes: direct connection, or with a SIP server. Direct mode is what you would expect: one device connects directly to another. -
Page 48: Real-Time Transport Protocol
The remote codec must be listening on that port for a connection, and that port must be open to the public network. On the Z/IP ONE, the RTP listen defaults to UDP port 9150. This can be configured on the second page of the Setup->Network menu on the front panel, or on the Network web page. -
Page 50: Making Connections
How you connect to another codec for the first time depends a bit on the type of stream you’re using. However, after that first time, most calls can be redialed from the Z/IP ONE’s call history, and all types of connections can be added to the Z/ IP ONE’s phone book. -
Page 51: Using The Phone Book
This field chooses how many attempts are made to automatically redial, or if the Z/IP ONE should try to redial forever. It can also be set to use whatever the system default redial setting is, in the Setup->System menu. - Page 52 MAKING CONNECTIONS | Browsing the ZIP Server If the contact you are adding is another Zephyr/IP, you can take advantage of the ZIP Server’s directory services. This can be used to reduce typing using the front panel keypad, or when you do not know the exact name of the Zephyr/IP you’re trying to reach.

Page 56: Ancillary Data
Ancillary Data Along with the coded audio, the Z/IP ONE is able to send associated data. One example of how this is used is for sending connection quality statistics to the remote Z/IP ONE. This data channel is also available to send user data to the remote codec. - Page 57 The eight general purpose outputs can each be set to one of nine operating modes: Off – the output signal is never asserted On – the output signal is always asserted (you can use this to verify that the Z/IP ONE is powered on and working) End-to-end –...
- Page 58 ANCILLARY DATA | Parallel Port There are 8 open-collector outputs, and 8 open-collector inputs, each configurable from the Settings menu in the user interface. The DB25 connector is pinned out as follows: DB25 Male Connector Parallel Outputs 1-8 Outputs are open collector to ground, and can sink up to 125mA of current each (actually, any output can sink up to 400mA, however the maximum combined current should be kept below 1000mA).
-
Page 59: Parallel Inputs
Z/IP ONE’s GPIO input signals. To do this, configure the Z/IP ONE to listen to a GPIO signal that does not exist. An easy way to guarantee this is to use the Z/IP ONE’s own IP address with port numbers of 3 and 4. This tells the Z/IP ONE not to use the parallel port for signal inputs, but it gives it a Livewire GPIO signal that will never change on its own. - Page 60 The device’s INPUT change is accompanied by a Livewire GPO message. Now, consider the Z/IP ONE: Although it has Livewire natively, it must present its input and output signals to the network in the same manner. You can think of it as having a tiny GPIO node stuffed in the same box – a status OUTPUT generates a Livewire GPI message: In this manner Livewire GPIO is analogous to Livewire Audio.
-
Page 61: Serial Data
In addition to GPIO data, the Z/IP ONE can send low-bitrate serial data. Where GPIO is a series of discrete signals, serial data is sent as a constant stream. The Z/IP ONE can transfer serial data at a sustained rate of 9600 bits per second, and can send binary data as well as text. -
Page 62: Appendix A When An It Department Is Not Available
WHEN AN IT DEPARTMENT IS NOT AVAILABLE | Appendix A - When an IT Department Is Not Availabdle There are times when an IT department is not on hand to guide you through some of the ins and outs of networking. This appendixappendix covers some of the basics to get you started. - Page 63 | Appendix A Before we get too deep into binary numbers, host and network address parts, you should be aware that you can safely treat the subnet mask as just another parameter to set when you configure an IP address. No deep understanding is required to find out what the local subnet mask is and to configure it for your IP device.
- Page 64 WHEN AN IT DEPARTMENT IS NOT AVAILABLE | IP Address Classes Find, you say. That was mildly entertaining. But why muck about with subnet masks and binary operations? Why can’t they just always use the first three bytes for the network ID and the last byte for the host ID? That is a fair question.

DHCP you don’t know the assigned IP address of the device, plus this address may change from time to time. This is usually not a problem, but in some cases it can be. If you need to configure the Z/IP ONE via a web interface, you will have to check the currently assigned IP address on the device via the front panel. - Page 66 The ipconfig command will give you the subnet mask, gateway, and DNS server addresses. It does not directly give you the IP address you should use on the Z/IP ONE. If DHCP is available, as it is in this example, you can just configure the Z/IP ONE to use DHCP.
-
Page 67: Find An Available Ip Address Without A Dhcp Server
| Appendix A Find an Available IP Address without a DHCP Server What can you do if a DHCP server is not available on your network? In this case, we’ll search for an IP address by pulling one out of a hat, then testing to see if it is already in use. In the example above, the PC’s address was 192.168.123.101, and the subnet mask was 255.255.255.0. -
Page 68: Duplicate Ip Addresses
The method to diagnose a duplicate IP address conflicting with your Z/IP ONE is to learn the hardware address (also call the physical or MAC address) of your Z/IP ONE, and to use the “arp -a” command from a PC to watch the hardware address associated with your Z/IP ONE’s IP address. -
Page 69: Network Address Translation
| Appendix A Network Address Translation What is it? Network Address Translation (NAT) is a technique that allows multiple IP devices on a private network to share a single public IP address. A NAT device has two network ports, one for the “private side” (the LAN) and one for the “public side”... - Page 70 On your Z/IP ONE, in the Setup->ZIP Server configuration page, enter a value for the listen port. The default value is zero, which tells the Z/IP ONE to select a port on its own. You can choose any value from 1024 to 65,535, but please make a note of it.

Page 72: Appendix B Audio Coding Reference
AUDIO CODING REFERENCE | Appendix B - Audio Coding Reference History Audio takes up a lot of data. Just a regular phone call uses 64,000 bits per second. Without data reduction, CD-quality audio – 16 bits ad 44.1 kHz sample rate – requires a transmission capability of about 706 thousand bits per second (kbps) for each audio channel. -
Page 73: Basic Principles Of Perceptual Coding
| Appendix B Basic Principles of Perceptual Coding With perceptual coding, only information that can be perceived by the human auditory system is retained. Lossless – which, for audio, translates to noiseless – coding with perfect reconstruction would be an optimum system, since no information would be lost or altered. - Page 74 AUDIO CODING REFERENCE | To benefit from the masking effects, perceptual coders use a filter bank to divide the input audio into multiple bands for analysis and processing. The maximum masked noise level is calculated depending on the spectral content, and the available bits are allocated so as to keep the quantization noise below the masking threshold at every point in the spectrum.
- Page 75 | Appendix B Important! Due to a perceptual coder’s reliance on precisely modeling principles of human perception, audio to be coded should not be processed with any non-linear dynamics processing, such as clipping, multi-band compression, or hard limiting. Wideband compression, or AGC, is acceptable, and may be desirable if consistent level cannot otherwise be achieved.

Page 76: Mpeg
2 is widely used for Digital Audio Broadcasting (DAB) in Europe, audio for video, and broadcast play-out systems. Layer 3 – which Telos was the first to use in the Zephyr – is widely used in broadcast codecs and has gone on to sig- nificant Internet and consumer electronics fame under the moniker derived from the file extension: MP3. - Page 77 | Appendix B AAC is a lot more sophisticated than the previous MPEG layers 2 and 3, providing significantly more coding power. Because it uses a modular approach, new ideas can be developed and plugged into the basic structure. This had the additional advantage that it was possible to combine the various components from different developers, taking the best pieces from each.
- Page 78 AUDIO CODING REFERENCE | Because AAC was built on a similar structure to Layer 3, it therefore retains some of its powerful features: Redundancy Reduction – a Huffman encoding process causes values that appear more frequently to be ♦ coded with shorter words, while values that appear only rarely are coded with longer words. This results in an overall increase in coding efficiency with no degradation, since it is a completely lossless process.
-
Page 79: Aac-Ld (Aac Low Delay)
| Appendix B And the researchers succeeded in achieving the ITU goal: AAC is the first codec system to fulfill the ITU require- ments for indistinguishable quality at 128 kbps/stereo. It has approximately 100% more coding power than Layer 2 and 30% more power than the former MPEG performance leader, Layer 3. - Page 80 AUDIO CODING REFERENCE | There are codecs using other than perceptual technologies that have lower delay, but they are not as powerful. That is, for a given bitrate, they do not achieve fidelity as good as the MPEG systems we have been examining. The common G.722 is an example.
