| 1 1 Introduction W elcome to the iP or t e T elos iP ort is designed to help you achieve one of two objectives: Connect two Livewire-equipped facilities over a wide-ar ea network, suc h that they ♦ appear to be local to each other . As many as 8 bi-directio nal channels are possible.
2 | Section 1 loss is routine such as on the public Internet. There are congurable bu ers to accommodate jitt er , but longer buer lengths add to dela y . When you need to use non-QoS- controlled links, the T elos Z/IP family products are a better choice because they hav e adaptive mechanisms to deal with netw ork problems.
INTRODUC TION | 3 e jack labeled 100/1000 is for the compressed streams, which is nor mally connected to a W ide Area Networ k link. It automatically adapts its rate to the port at the other end of the connection. F or both jacks, the iP or t ’ s Ethernet mode is set per manently to AUTO , so the other end must be, as well.
4 | Section 1 factor y defaults. F irmware setup . Restart. Diagnost ics ♦ - Vie w and capture system diagnostics info. e first step is going to be to configure the networ k parameters, so click on the Network link to open that page.
INTRODUC TION | 5 How ever , if you do w ant only one connection to the iPort, then it’ s OK to enter the same subnet for both elds. In this case, both the Live wire and codec streams will be on whichev er single physical port you con- nect. The other should remain unconnected.
6 | Section 1 T o install new fir mware , the first step is to downloa d it to your PC. Y ou might receive this via email f rom our support department, or you might find it o n our website. Af ter it is on your PC, browse to locate it, then click the Upload button to install it into the iP or t.
| 7 2 Livewir e -W AN Link Livewire is a professional-grade IP Audio system, used over controlled local area networks. As a modern replacement for older analog or TDM digital sy stems, it offers very low delay and high audio fidelity .
8 | Section 2 equipment, y ou’ d have a rack full of codec boxes, expensive router interface cards, and a plethora of cables. If you don ’t alr eady have a Liv ewire installation, no problem. Y ou can use an audio inter face Node, or two, and still benefit f rom the iP ort ’ s simplicity and low cost.
LIVEWIREW AN LINK | 9 Network Click on the Network link, and you will see this page: Host Name Enter a convenient name , if y ou want to change f rom the Zephyr default. (A dvanced note: is is the Linux host name, used f or network identification.
10 | Section 2 C odec congur ation Global Options Confirm that the factor y default is set for 8 encoder / decoder channels. (e 16-channel encode-only option is used for streaming applications.
LIVEWIREW AN LINK | 11 Decoder e Buffer ing drop-down bo x lets you choose how m uch buffer is applied to the received streams. A lower value gives lower delay , but depends upon the networ k to have low jit- ter . ere ar e a range of values, so that y ou can experiment to find the optimum for your network conditions.
12 | Section 2 selected on the Diagnostics page. ese are mostly intended for our engineers. Should you have a problem that might be diagnosable via these logs, our suppor t people will ask you to download and email us the files. F A Qs Do all the channels need to go to a single unit at the other end? No .
LIVEWIREW AN LINK | 13 AA C-LD has the low est delay of the codecs, so is the c hoice when inter-activity is ♦ important, such as for intercoms. It has about 30% less efficiency than AA C, which means that for equal quality , you would need to use 30% higher bitrate.

STREAMING | 15 3 Str eaming W hen used with an appropriate ser ver , the iP ort can be used as a simple, reliable encoder for Internet or internal audio distr ibution. Bec ause the iP ort generates standards-based MPEG streams, a wide variety of PC-hosted and hardware play ers can be used for listen- ing.
16 | Section 3 there must be a har dware N ode somewhere on the network to pr ovide the timing c lock.) An installation which already has Livewire equip ment would not need a Node dedicated to the iP ort - you would just select the channels you want to stream directly f rom the Livewire network.
STREAMING | 17 Select ‘ TCP ’ as the protocol (used for the iP ort to ser ver link) 5. Click the box 6. Enable SHOU T cast and enter a passwor d that will be used by the ser ver to authenticate the stream Install, configure , and star t the ser ver (Steamc ast for our example) Install Steamc ast and its support files the host PC 7.
18 | Section 3 Clicking on Options gets us to the page that lets us enter the codec details. F or this first stream, we’ve chosen the MP3 encoder , and a high-qualit y 128kbps bitrate. For communication with streaming servers, the Pr otocol type will be T CP .
STREAMING | 19 web broadcast. S teamcast ’ s backend XML sheets are supported by other ser vices such as L oudCity for royalty requirements and the interface is also utilized by several IRC and PHP projects to inc lude stats in var ying listener loc ations.
20 | Section 3 ; Steamcast Configuration F ile ; ================================ ; is is the default Steamc ast ser ver configuration file, f eel f ree to use ; it as a template for your ser ver’ s configuration. All lines beginning with ; ; or blank are ignor ed by the ser ver’ s configuration parser .
STREAMING | 21 ; also enables steamcast ’ s auto extension feature so that the server will assign the correct ; extension to your mount points based o n the audio format/codec in use. MimeF ile=mime.ty pes ; BanF ile [None|*steamcast.ban]: U se this var iable to specify the location of your ban file.
22 | Section 3 ; ClientTimeout [*30]: N umber of seconds a listener/viewer should stay connected while no ; source exists for thier mount. ClientTimeout=30 ; User Configuration ; ================== ;.
STREAMING | 23 ; UserMaxes co mbined exceed the global UserMax then the U serMax takes presedence. SourceUserMax=5 ; SourceRelay : is particular mount will pull data f rom the location specified below . ; If you publish both servers on yp.shoutcast.
24 | Section 3 ; publishing outlets. Y ou can use %s anywhere in the title to have the encoder’ s option included ; into the final stream name. ; SourceNameF ormat=%s powered by Steamcast ; SourceIsDefault [*Y es|No]: Setting this to Y es will make this particular ; mount available globally .
STREAMING | 25 ; ser vices. ; SourcePublicRelays=Y es ; SourceRawKey : Set this variable to the key you would like passed in a parameter string to ; access the raw data stream in HT TP form.
26 | Section 3 ; Ser vI P=ANY ; SrcIP [*Any]: SrcIP is the IP that S teamcast will listen f or source connectio ns. F or ; instance setting this option to 127.0.0.1 will limit SHOU T c ast source connection attempts ; to only f rom the the machine steamcast resides on.
