Chapter 12SIP MAX-200HW2 Series User’s Guide 153 12.1.7.2 Use NAT If you know the NAT router’s public IP address and SIP port number, you can use the Use NAT feature to manually configure the ZyXEL Device to use a them in the SIP messages. This eliminates the need for STUN or a SIP ALG. You must also configure the NAT router to forward traffic with this port number to the ZyXEL Device. 12.1.7.3 STUN STUN (Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators) allows the ZyXEL Device to find the presence and types of NAT routers and/or firewalls between it and the public Internet. STUN also allows the ZyXEL Device to find the public IP address that NAT assigned, so the ZyXEL Device can embed it in the SIP data stream. STUN does not work with symmetric NAT routers or firewalls. See RFC 3489 for details on STUN. The following figure shows how STUN works. 1The ZyXEL Device (A) sends SIP packets to the STUN server (B). 2The STUN server (B) finds the public IP address and port number that the NAT router used on the ZyXEL Device’s SIP packets and sends them to the ZyXEL Device. 3The ZyXEL Device uses the public IP address and port number in the SIP packets that it sends to the SIP server (C). Figure 102 STUN 12.1.7.4 Outbound Proxy Your VoIP service provider may host a SIP outbound proxy server to handle all of the ZyXEL Device’s VoIP traffic. This allows the ZyXEL Device to work with any type of NAT router and eliminates the need for STUN or a SIP ALG. Turn off a SIP ALG on a NAT router in front of the ZyXEL Device to keep it from retranslating the IP address (since this is already handled by the outbound proxy server). 12.1.8 Voice Coding A codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital signals back into voice signals. The ZyXEL Device supports the following codecs. •G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures analog signal amplitudes at regular time intervals (sampling) and converts them into digital bits (quantization). Quantization “reads” the analog signal and then “writes” it to the nearest digital value. For this reason, a digital sample is usually slightly different from its analog original (this difference is known as “quantization noise”). Chapter 12SIP MAX-200HW2 Series User’s Guide 154 G.711 provides excellent sound quality but requires 64kbps of bandwidth. •G.723 is an Adaptive Differential Pulse Code Modulation (ADPCM) waveform codec. Differential (or Delta) PCM is similar to PCM, but encodes the audio signal based on the difference between one sample and a prediction based on previous samples, rather than encoding the sample’s actual quantized value. Many thousands of samples are taken each second, and the differences between consecutive samples are usually quite small, so this saves space and reduces the bandwidth necessary. However, DPCM produces a high quality signal (high signal-to-noise ratio or SNR) for high difference signals (where the actual signal is very different from what was predicted) but a poor quality signal (low SNR) for low difference signals (where the actual signal is very similar to what was predicted). This is because the level of quantization noise is the same at all signal levels. Adaptive DPCM solves this problem by adapting the difference signal’s level of quantization according to the audio signal’s strength. A low difference signal is given a higher quantization level, increasing its signal-to-noise ratio. This provides a similar sound quality at all signal levels. G.723 provides high quality sound and requires 20 or 40 kbps. •G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec. It uses a filter based on information about how the human vocal tract produces sounds. The codec analyzes the incoming voice signal and attempts to synthesize it using its list of voice elements. It tests the synthesized signal against the original and, if it is acceptable, transmits details of the voice elements it used to make the synthesis. Because the codec at the receiving end has the same list, it can exactly recreate the synthesized audio signal. G.729 provides good sound quality and reduces the required bandwidth to 8kbps. 12.1.9 PSTN Call Setup Signaling PSTNs (Public Switched Telephone Networks) use DTMF or pulse dialing to set up telephone calls. Dual-Tone Multi-Frequency (DTMF) signaling uses pairs of frequencies (one lower frequency and one higher frequency) to set up calls. It is also known as Touch Tone? Each of the keys on a DTMF telephone corresponds to a different pair of frequencies. Pulse dialing sends a series of clicks to the local phone office in order to dial numbers. 3 12.1.10 MWI (Message Waiting Indication) Enable Message Waiting Indication (MWI) enables your phone to give you a message–waiting (beeping) dial tone when you have one or more voice messages. Your VoIP service provider must have a messaging system that sends message-waiting-status SIP packets as defined in RFC 3842. 3.The ZyXEL Device supports DTMF at the time of writing. Chapter 12SIP MAX-200HW2 Series User’s Guide 155 12.1.11 Custom Tones (IVR) IVR (Interactive Voice Response) is a feature that allows you to use your telephone to interact with the ZyXEL Device. The ZyXEL Device allows you to record custom tones for the Caller Ringing Tone and On Hold Tone functions. The same recordings apply to both the caller ringing and on hold tones. 12.1.11.1 Recording Custom Tones Use the following steps if you would like to create new tones or change your tones: 1Pick up the phone and press **** on your phone’s keypad and wait for the message that says you are in the configuration menu. 2Press a number from 1101~1108 on your phone followed by the # key. 3Play your desired music or voice recording into the receiver’s mouthpiece. Press the # key. 4You can continue to add, listen to, or delete tones, or you can hang up the receiver when you are done. 12.1.11.2 Listening to Custom Tones Do…

Report No.: SA961108H05 1 RF EXPOSURE REPORT REPORT NO.: SA961108H05 MODEL NO.: MAX-200HW2 ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: ZyXEL Communications Corporation ADDRESS: No. 6, Innovation Road II, Science-Park, Hsin-Chu, 300, Taiwan ISSUED BY: Advance Data Technology Corporation LAB LOCATION: No. 81-1, Lu Liao Keng, 9 Ling, Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien, Taiwan, R.O.C. Report No.: SA961108H05 2 RF Exposure Measurement 1. Introduction In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500 ... ...

Friis Formula Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1 mW/cm 2 . If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance 20cm. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4. EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5. Classification The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device Report No.: SA961108H05 4 6.
