2.3.10 Upgrading the Phones Firmware
When it is time to upgrade your phones firmware, your telephone network administrator will configure the IP PBX to which the V300 is connected to automatically check your phones existing firmware and compare it to the firmware on an official ZyXEL server. If your firmwares version number does not match, the IP PBX will then initiate the upgrade process: 1 When the IP PBX is ready to process your phone, it rings you while the phone is on the hook. As soon as you answer, an automated message asks if you want to change your V300s firmware. 2 Enter * # on the V300s keypad to answer Yes. Enter # # on the V300s keypad to answer No. 3 If you entered Yes, then the phone begins downloading the new firmware from the IP PBX. The download and install process may take some time, depending on the size of the update and any network congestion. 4 When the download and install process completes, the V300 restarts. You may need to log into your account again.
Do not turn off or attempt to use your V300 during a firmware update.

3.3 Enabling and Disabling Features
Many of the V300s LCD screen menus allow you check a features settings and then edit the setting. Take the following steps to check a features current setting and then enable or disable the feature. This example uses the DHCP feature. 1 Select the feature you want to configure. In this example, press MENU to enter the menu system, then select Adv Setting. In the Adv Setting menu, select DHCP. The following screen displays:

Figure 8 Example: DHCP

1. DHCP Off
2 To change the setting to ON, press.
If later you decide you want to use static IP or PPPoE, then you do not need to come into the DHCP menu to disable it; rather, just go into one of those other menus and enable one of them. This automatically turns DHCP off.
3.4 Entering Numbers, Letters and Symbols
When you enter information into the V300 (when setting up a phonebook entry, for example) you may need to enter different kinds of characters. The alphanumeric keypad has four input modes: Number mode Uppercase mode Lowercase mode Symbol mode
Use the # key to cycle between modes.
Not all modes are available in all screens.
When you press a key to enter a character, wait a short time until the cursor moves on to the next space. Press a key multiple times to access the different characters. For example, in Uppercase mode press 9 four times to enter Z.
The following table shows the numbers, letters and symbols you can enter.

13.5 Dynamic DNS

Dynamic DNS allows you to map your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you. SIP IP phones can access the SIP server on the V300 using a domain name (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name. The Dynamic DNS service provider will give you a password or key. Click Maintenance > System > Dynamic DNS. The screen appears as shown. Use this screen to change your V300s DDNS settings.

Wall-mounting Instructions
Complete the following steps to hang your V300 on a wall.
See Table 48 on page 149 for the size of screws to use and how far apart to place them.
1 Select a position free of obstructions on a sturdy wall. 2 Drill two holes for the screws.
Be careful to avoid damaging pipes or cables located inside the wall when drilling holes for the screws.
3 Do not insert the screws all the way into the wall. Leave a small gap of about 0.5 cm between the heads of the screws and the wall. 4 Make sure the screws are snugly fastened to the wall. They need to hold the weight of the V300 with the connection cables. 5 Align the holes on the back of the V300 with the screws on the wall. Hang the V300 on the screws.

Setting Up Your Computers IP Address
Your specific ZyXEL device may not support all of the operating systems described in this appendix. See the product specifications for more information about which operating systems are supported.
This appendix shows you how to configure the IP settings on your computer in order for it to be able to communicate with the other devices on your network. Windows Vista/XP/2000, Mac OS 9/OS X, and all versions of UNIX/LINUX include the software components you need to use TCP/IP on your computer. If you manually assign IP information instead of using a dynamic IP, make sure that your networks computers have IP addresses that place them in the same subnet. In this appendix, you can set up an IP address for: Windows XP/NT/2000 on page 156 Windows Vista on page 159 Mac OS X: 10.3 and 10.4 on page 163 Mac OS X: 10.5 on page 166 Linux: Ubuntu 8 (GNOME) on page 169 Linux: openSUSE 10.3 (KDE) on page 173

Notation

Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a / followed by the number of bits in the mask after the address. For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128. The following table shows some possible subnet masks using both notations.

Subnetting

You can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons. In this example, the company network address is 192.168.1.0. The first three octets of the address (192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum of or 254 possible hosts. The following figure shows the company network before subnetting.
Figure 167 Subnetting Example: Before Subnetting
You can borrow one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or /25). The borrowed host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25. The following figure shows the company network after subnetting. There are now two subnetworks, A and B.
Figure 168 Subnetting Example: After Subnetting
In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of or 126 possible hosts (a host ID of all zeroes is the subnets address itself, all ones is the subnets broadcast address). 192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126. Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.
