Overview Installation Troubleshooting Contact FAQ Specifications Glossary LicenseConfiguration: Basic Advanced TCP/IP Wireless VT2400/VT2500 Series Voice Gateway User Guide 10InstallationFollow the steps and guidelines in this section to physically set up and position the VT2400/VT2500 voice gateway on a flat surface or mount it on the wall.Positioning Your Router for Optimal Wireless Performance (VT2500 only)Your voice gateway has an embedded wireless router that uses a radio transmission technology defined by the Institute of Electrical and Electronics Engineers (IEEE) called 802.11 Wireless Fidelity (Wi-Fi). This standard is subdivided into distinct categories of speed and the frequency spectrum used, designated by the lowercase letter after the standard. For example, the router supports both the ‘b’ and ‘g’ specifications. The 802.11b specification transmits data rates up to 11 Mbps while the 802.11g specification transmits data rates up to 54 Mbps. These are theoretical standards so performance may vary. The radio waves radiate in a donut-shaped pattern. The waves travel through walls and floors, but transmission power and distance are affected. The theoretical distance limit is 1,000 feet (305 meters), but actual throughput and distance varies.Both standards operate in the 2.4 GHz range, meaning other electrical appliances also might interfere with the router – televisions, radios, microwave ovens, or 2.4 GHz cordless telephones. Therefore, positioning the voicegateway where it encounters the least interference helps maintain a better connection.The following table lists the expected wireless range of the router. This table is only a guide and coverage varies due to local conditions.To achieve the best wireless performance, review these guidelines before deciding where to place the voicegateway:•Placing the voice gateway in the center of your network is the best location because the antenna sends out the signal in all directions.•Placing the voice gateway in a higher location, such as on top of a cabinet, helps disperse the signal cleanly, especially to receiving locations on upper stories.•If possible, position the voice gateway so there is direct line of sight between the unit and your other home network devices.•Avoid placing the voice gateway next to large solid objects like computer cases, monitors, walls, fireplaces, etc. This helps the signal penetrate more cleanly.•Other wireless devices such as televisions, radios, microwaves, and 2.4 GHz cordless telephones can interfere with the signal. Keep these devices away from the voice gateway.•Mirrors, especially silver-coated, can reduce transmission performance.Data Rate Open Area Closed Area54 Mbps Up to 100 ft (30m) Up to 60 ft (18 m)11 Mbps Up to 900 feet (275 m) Up to 160 feet (49 m)5.5 Mbps Up to 1300 feet (396 m) Up to 200 feet (61 m)2 or 1 Mbps Up to 1500 feet (457 m) Up to 300 feet (91 m)

For example, to ensure that they always receive the same private IP address, you can reserve IP addresses for a private FTP server or gaming DMZ device.You may reserve up to 16 IP addresses for CPEs on your LAN that are assigned by the voice gateway’s DHCP server. You may want to reserve an IP address on your LAN for a particular server (such as a private FTP server) to ensure the designated server always receives the same private IP address.MAC Address Type the MAC address of the DHCP client for which a reserved IP address is required. The format is 16 hexadecimal numerals. NOTE: If the MAC Address you entered already has an IP Address assigned and is listed in the CURRENT DHCP LEASES table as Dynamic on the Gateway > LAN — dhcp leases page, you must reserve the same IP Address that is listed there for this MAC Address.

This represents a mapping of one public IP address to many private IP addresses. Using NAT, you can support up to 253 clients on your private LAN. If NAT is disabled, then the voice terminal DHCP server is also disabled. In this case, none of the client devices on your private internal LAN will be assigned an IP address from the voice terminal DHCP server. Instead, your clients are treated as passthrough devices, and if they are configured to use DHCP, they will attempt to obtain a public IP address from your ISP.Local PortAdd (button) Click Add to save this virtual server to the PORT FORWARDING list.

DHCP eliminates the need to manually assign static IP addresses by “leasing” an IP address and subnet mask to each client. It enables the automatic reuse of unused IP addresses.The VT2500 is simultaneously a DHCP client and a DHCP server. •A DHCP server at the cable system headend assigns a public IP address to the VT2500 and optionally to clients on the VT2500 LAN.•The VT2500 contains a built-in DHCP server that assigns private IP addresses to clients.distortion An undesired change in signal waveform within a transmission medium. A nonlinear reproduction of the input waveform.DMZ A “de-militarized zone” is one or more hosts logically located between a private LAN and the Internet. A DMZ prevents direct access by outside users to private data. (The term comes from the geographic buffers located between some conflicting countries, such as North and South Korea.) In a typical small DMZ configuration, the DMZ host receives requests from private LAN users to access external web sites and initiates sessions for these requests. The DMZ host cannot initiate a session back to the private LAN. Internet users outside the private LAN can access only the DMZ host. You can use a DMZ to set up a web server or for gaming without exposing confidential data.DNS The Domain Name System is the Internet system for converting domain names to IP addresses. A DNS server contains a table matching domain names such as Internetname.com to IP addresses such as 192.169.9.1. When you access the world-wide web, a DNS server translates the URL displayed on the browser to the destination website IP address. The DNS lookup table is a distributed Internet database; no one DNS server lists all domain name to IP address matches.DOCSIS The CableLabs Data-Over-Cable Service Interface Specification defines interface standards for cable modems, gateways, and supporting equipment to deliver data between an HFC network and computer systems or television sets. To emphasize its use as a cable modem standard, DOCSIS is now called CableLabs Certified Cable Modems. Euro-DOCSIS is DOCSIS adapted for use in Europe.domain name A unique name, such as motorola.com, that maps to an IP address. Domain names are typically much easier to remember than are IP addresses.dotted-decimal formatMethod of representing an IP address or subnet mask using four decimal numbers called octets. Each octet represents eight bits. In a class CIP address, the octets are “network.network.network.host.” The first three octets together represent the network address and the final octet is the host address. In the VT2500 LAN default configuration, 192.168.100 represents the network address. In the final octet, the host address can be from 2 to 254.
