– 21 –1INTRODUCTIONThe Barricade Wireless Broadband Router (SMC7901WBRA2 B1) provides a built-in ADSL modem and IEEE 802.11b/g wireless access point, all in one compact unit. The router enables multiple wired and wireless users to securely access the Internet through a single-user account with the ADSL service provider.KEY HARDWARE FEATURESThe following table describes the main hardware features of the ADSL Router.DESCRIPTION OF CAPABILITIES◆Internet connection through an RJ-11 WAN port.◆Local network connection through one 10/100 Mbps Ethernet port.◆On-board IEEE 802.11 b/g 54 Mbps wireless access point.◆DHCP for dynamic IP configuration, and DNS for domain name mapping.◆Firewall with Stateful Packet Inspection, client privileges, intrusion detection, and NAT.Table 1: Key Hardware Features Feature DescriptionAntennas One 2.4 GHz antenna.LAN Port One 100BASE-T RJ-45 port.Phone Port One RJ-11 port for connection to a standard POTS telephone line.On/Off Button Powers the unit on and off.Reset Button Restores factory defaults.LEDs Indicators for system status, wireless radio status, and LAN port status.Mounting Options Can be mounted on any horizontal surface such as a desktop or shelf, or on a wall or ceiling using two screws.
CHAPTER 1 | IntroductionDescription of Capabilities– 22 –◆NAT also enables multi-user Internet access via a single user account, and virtual server functionality (providing protected access to Internet services such as Web, FTP, e-mail, and Telnet).◆VPN pass-through (IPSec-ESP Tunnel mode, L2TP, PPTP).◆User-definable application sensing tunnel supports applications requiring multiple connections.◆Easy setup through a Web browser on any operating system that supports TCP/IP.◆Compatible with all popular Internet applications.In addition, the access point functionality offers full network management capabilities through an easy to configure web interface, and support for Simple Network Management tools.APPLICATIONS Many advanced networking features are provided by the Barricade:◆Wireless and Wired LAN — The Barricade provides connectivity to wired 10/100 Mbps devices, and wireless IEEE 802.11b compatible devices, making it easy to create a network in small offices or homes.◆Internet Access — This device supports Internet access through a DSL connection. Since many DSL providers use PPPoE or PPPoA to establish communications with end users, the Barricade includes built-in clients for these protocols, eliminating the need to install these services on your computer.◆Shared IP Address — The Barricade provides Internet access for up to 253 users via a single shared IP address. Using only one ISP account, multiple users on your network can browse the Web at the same time.◆Virtual Server — If you have a fixed IP address, you can set the Barricade to act as a virtual host for network address translation. Remote users access various services at your site using a constant IP address. Then, depending on the requested service (or port number), the Barricade can route the request to the appropriate server (at another internal IP address). This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal IP addresses without affecting outside access to your network.◆DMZ Host Support — Allows a networked computer to be fully exposed to the Internet. This function is used when NAT and firewall security prevent an Internet application from functioning correctly.
CHAPTER 1 | IntroductionPackage Contents– 23 –◆Security — The Barricade supports security features that deny Internet access to specified users, or filter all requests for specific services the administrator does not want to serve. The Barricade’s firewall also blocks common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding. WEP (Wired Equivalent Privacy), SSID, and MAC filtering provide security over the wireless network.◆Virtual Private Network (VPN) — The Barricade supports three of the most commonly used VPN protocols – PPTP, L2TP, and IPSec. These protocols allow remote users to establish a secure connection to their corporate network. If your service provider supports VPNs, then these protocols can be used to create an authenticated and encrypted tunnel for passing secure data over the Internet (i.e., a traditionally shared data network). The VPN protocols supported by the Barricade are briefly described below.◆Point-to-Point Tunneling Protocol — Provides a secure tunnel for remote client access to a PPTP security gateway. PPTP includes provisions for call origination and flow control required by ISPs. L2TP merges the best features of PPTP and L2F. Like PPTP, L2TP requires that the ISP’s routers support the protocol.◆IP Security — Provides IP network-layer encryption. IPSec can support large encryption networks (such as the Internet) by using digital certificates for device authentication.PACKAGE CONTENTSThe Barricade Wireless Broadband Router package includes:◆Barricade Wireless Broadband Router◆RJ-45 Category 5 network cable◆RJ-11 telephone cable◆Splitter◆AC power adapter◆Four rubber feet◆Quick Installation Guide◆Documentation CD◆SMC warranty information card
CHAPTER 1 | IntroductionHardware Description– 24 –Inform your dealer if there are any incorrect, missing or damaged parts. If possible, retain the carton, including the original packing materials. Use them again to repack the product in case there is a need to return it.HARDWARE DESCRIPTIONThe Barricade Wireless Broadband Router, from herein refered to as ADSL Router, contains an integrated DSL modem and connects to the Internet or to a remote site using its RJ-11 WAN port. It connects directly to your PC or to a local area network using its RJ-45 Fast Ethernet LAN port or via a wireless network adapter.Access speed to the Internet depends on your service type. Theoretically ADSL2+ provides up to 24 Mbps downstream and 3.5 Mbps upstream. However, this depends on the distance between your home and the central office (CO) of the service provider. Actual rates provided by specific broadband service providers may vary dramatically from these upper limits due to both distance and type of deployment of DSLAM equipment. Typically a modern domestic broadband connection can reach maximum download speeds dependent on your port capabilities and upload speeds usually set at a slower rate. This again is dependent on your service provider and what contract you sign with them.Using the ADSL Router data passing between devices connected to your local area network can run at up to 100 Mbps over the Fast Ethernet ports and up to 54 Mbps over the built-in wireless network adapter.The ADSL Router includes an LED display on the front panel for system power and port indications that simplifies installation and network troubleshooting.

Position the Antenna – The antenna emits a radiation pattern that is toroidal (doughnut shaped), with the coverage extending most in the direction perpendicular to the antenna. Therefore, the antenna should be oriented so that the radio coverage pattern fills the intended horizontal space. For example, if the ADSL Router is mounted on a horizontal surface, the antenna should be positioned pointing vertically up to provide optimum coverage.

Any PC directly attached to the unit can access the management interface using a web browser, such as Internet Explorer (version 6.0 or above).ISP SETTINGSIf you are not sure of your connection method, please contact your Internet Service Provider. There are several connection types to choose from: Static IP, DHCP, PPPoE, PPPoA, PPTP and L2TP. NOTE: If using the PPPoE option, you will need to remove or disable any PPPoE client software on your computers.CONNECTING TO THE LOGIN PAGEIt is recommended to make initial configuration changes by connecting a PC directly to the ADSL Router’s LAN port. The ADSL Router has a default IP address of 192.168.2.1 and a subnet mask of 255.255.255.0. You must set your PC IP address to be on the same subnet as the ADSL Router (that is, the PC and ADSL Router addresses must both start 192.168.2.x).To access the ADSL Router’s management interface, follow these steps:1. Use your web browser to connect to the management interface using the default IP address of 192.168.2.1.2. Log into the interface by entering the default username “admin” and password “smcadmin,” then click Login.NOTE: It is strongly recommended to change the default user name and password the first time you access the web interface.

CHAPTER 5 | WAN ConfigurationADSL Settings– 64 –ADSL SETTINGSThe ADSL Settings page configures the ADSL modulation type, ADSL2+ related parameters, capabilities and the ADSL tone mask.Figure 29: ATM SettingsThe following items can be enabled on this page:ADSL MODULATION ADSL Modulation refers to a frequency-division multiplexing (FDM) scheme utilized as a digital multi-carrier modulation method for DSL. A large number of closely-spaced orthogonal sub-carriers are used to carry data. The data is divided into several parallel data streams or channels, one for each sub-carrier. Each sub-carrier is modulated with a conventional modulation scheme (such as G.lite, ADSL2, etc. or more commonly ADSL2+).◆G.lite — A standard that defines the more economical splitterless ADSL connection that transmits data at up to 1.5 Mbps downstream and 512 Kbps upstream. This ADSL option can be installed without an on-site visit by the service provider.◆G.dmt — A standard that defines full-rate ADSL, and utilizes Discrete Multi-Tone (DMT) signaling to transmit data at up to 8 Mbps downstream and 640 Kbps upstream.
CHAPTER 5 | WAN ConfigurationADSL Settings– 65 –◆T1.413 — ANSI standard that defines the requirements for ADSL for the interface between the telecommunications network and the customer installation in terms of their interaction and electrical characteristics. (The Gateway complies with Issue 2 of this standard.)◆ADSL2 — This standard extends the capability of basic ADSL data rates to 12 Mbit/s downstream and 3 Mbit/s upstream (with a mandatory capability of ADSL2 transceivers of 8 Mbit/s downstream and 800 Kbit/s upstream.◆ADSL2+ — This standard extends the capability of basic ADSL data rates to 24 Mbit/s downstream and 1.4 Mbit/s upstream depending on the distance from the DSLAM to the customer's home.ANNEXL OPTION Annex L is an optional specification in the ITU-T ADSL2 recomendation G.992.3 titled “Specific requirements for a Reach Extended ADSL2 (READSL2) system operating in the frequency band above POTS.” It is often referred to as Reach Extended ADSL2 or READSL2.◆Enabled — Once enabled AnnexL increases the range of DSL service, enabling the link to work at a distance of 7 kilometers, or 23,000 feet.ANNEXM OPTION Annex M is an optional specification in ITU-T recomendations G.992.3 (ADSL2) and G.992.5 (ADSL2+), also referred to as ADSL2 M and ADSL2+ M. This specification extends the capability of commonly deployed Annex A by more than doubling the number of upstream bits.◆Enabled — Once enabled AnnexM increases upload speeds by the shifting the upstream/downstream frequency split from 138 kHz up to 276 kHz, allowing the maximum upstream bandwidth to be increased from 1.4 Mbit/s to 3.3 Mbit/s.ADSL CAPABILITY ADSL Capability refers to means of manipulating the bit loading of a connection to increase quality of signal or transmission rate.◆Bitswap — Enables bit swapping. Bit swapping is a way of swapping the bit-loading of a noisy tone with another tone in the symbol which is not as noisy. The bit loading from a specific tone can be increased or decreased. In addition, the TX power can be increased or decreased for a specific tone. However, there is no change in the overall payload rate after the bit swap operation.◆SRA — Enables seamless rate adaptation to set the optimal transmission rate based on existing line conditions.
CHAPTER 5 | WAN ConfigurationADSL Settings– 66 –ADSL TONE DSL technology employs a discrete multi-tone apparatus over standard wired telephone lines. Tone levels can be masked to avoid overlap, crosstalk and help echo cancellation. ADSL is a duplexed signal that allows doubling of the standardized discrete multi-tone (DMT) system that uses 256 “tones” that are each 4.3125 kHz wide in the forward (downstream) direction. The ATIS (Alliance For Telecommunications Information Solutions) Asymmetric Digital Subscriber Lines standard allows a total of 512 subchannels or “tones.” Each of these can be masked. Figure 30: Tone Mask..The following items can be enabled on this page:◆Tone number — The number of the tone (subchannel). (Range: 0~511)◆Select — Selects the tone to mask.◆Apply Changes — Clicking “Apply Changes” masks the specified tones.◆Mask All — Masks all tones, 0-511.◆UnMask All — Un-masks all checked tones.

NO DHCP By selecting none, you can disable DHCP on the ADSL Router.Figure 32: No DHCPThe following items are displayed on this page:◆None — Disables DHCP on the unit.
CHAPTER 6 | LAN ConfigurationDHCP Settings– 71 –DHCP RELAY Dynamic Host Configuration Protocol (DHCP) can dynamically allocate an IP address and other configuration information to network clients that broadcast a request. To receive the broadcast request, the DHCP server would normally have to be on the same subnet as the client. However, when the access point’s DHCP relay agent is enabled, received client requests can be forwarded directly by the access point to a known DHCP server on another subnet. Responses from the DHCP server are returned to the access point, which then broadcasts them back to clients.Figure 33: DHCP RelayThe following items are displayed on this page:◆DHCP Relay — Enables routing of the DHCP service to units on a different subnet.◆DHCP Server Address — Enter the address of the DHCP server for routing to other units.
CHAPTER 6 | LAN ConfigurationDHCP Settings– 72 –DHCP SERVER The unit can support up to 253 local clients. Addresses are assigned to clients from a common address pool configured on the unit.

– 75 –7WLAN CONFIGURATIONThis chapter describes wireless configuration on the ADSL Router. The unit contains an onboard IEEE 802.11b/g access point (AP), which provides wireless data communications between the router and wireless devices.WLAN Configuration contains the following sections:◆“WLAN Basic Settings” on page 76◆“Second BSSID” on page 77◆“Wireless Security Setup” on page 78◆“WPA Security” on page 81◆“Access Control” on page 82◆“WDS” on page 83◆“Advanced Settings” on page 85
CHAPTER 7 | WLAN ConfigurationWLAN Basic Settings– 76 –WLAN BASIC SETTINGSThe unit’s access point can function in one of three modes, mixed 802.11b/g, 802.11b only, or 802.11g only. Also note that 802.11g is backward compatible with 802.11b at slower data rates.Note that the unit supports two virtual access point (VAP) interfaces.Figure 36: WLAN Basic SettingsThe following items are displayed on this page:◆Disable Wireless LAN Interface — Disables the Wireless LAN interface. (Default: Enabled)◆Band — Defines the radio mode. (Default: 2.4Ghz (B+G))◆Mode — The unit can function as an access point alone allowing connection to wireless clients, or both access point and WDS (wireless distribution system) allowing WDS transparent bridging between APs. (Default: AP)◆SSID — The service set identifyer for the access point. (Default: SMCAP)◆Channel Number — The radio channel that the ADSL Router uses to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least five channels apart to avoid interference with each other. For example, you can deploy up to three access points in the same area using channels 1, 6, 11. Note that wireless clients automatically set the channel to the same as that used by the ADSL Router to which it is linked. (Default: Auto; Range: 1~11)◆Radio Power (mW) — Adjusts the power of the radio signals transmitted from the access point. The higher the transmission power,
CHAPTER 7 | WLAN ConfigurationSecond BSSID– 77 –the farther the transmission range. Power selection is not just a trade off between coverage area and maximum supported clients. You also have to ensure that high-power signals do not interfere with the operation of other radio devices in the service area. (Default: 60mW; Range: 60mW, 30mW, 15 mW)SECOND BSSIDThis page configures a second VAP (virtual access point) on the ADSL Router. Each VAP functions as a separate access point, and can be configured with its own Service Set Identification (SSID) and security settings. However, most radio signal parameters apply to both VAP interfaces.The VAPs function similar to a VLAN, with each VAP mapped to its own VLAN ID. Traffic to specific VAPs can be segregated based on user groups or application traffic. Each VAP can have up to 64 wireless clients, whereby the clients associate with these VAPs the same as they would with a physical access point. Figure 37: Second BSSIDThe following items are displayed on this page:◆Enable — Enables a second VAP on the wireless interface. (Default: Disabled)◆SSID — Configures the service set identifier of a second VAP (VAP0) on the wireless interface. (Default: SMCAP-1)

TKIP is used as the multicast encryption cipher.■WPA2(AES): WPA2 – WPA was introduced as an interim solution for the vulnerability of WEP pending the ratification of the IEEE 802.11i wireless security standard. In effect, the WPA security features are a subset of the 802.11i standard. WPA2 includes the now ratified 802.11i standard, but also offers backward compatibility with WPA. Therefore, WPA2 includes the same 802.1X and PSK modes of operation.■WPA2(Mixed): Clients using WPA or WPA2 are accepted for authentication.The following figures illustrate the various options available with each security setting:

CHAPTER 7 | WLAN ConfigurationAdvanced Settings– 85 –ADVANCED SETTINGSThe advanced radio configuration settings are described in the page that follows.Figure 45: Wireless Security Setup - Advanced SettingsThe following items are displayed on this page:◆Fragment Threshold — Configures the minimum packet size that can be fragmented when passing through the wireless interface. Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Range: 256-2346 bytes; Default: 2346 bytes)◆RTS Threshold — Sets the packet size threshold at which a Request to Send (RTS) signal must be sent to a receiving station prior to the sending station starting communications. The wireless interface sends RTS frames to a receiving station to negotiate the sending of a data frame. After receiving an RTS frame, the station sends a CTS (clear to send) frame to notify the sending station that it can start sending data.◆Beacon Interval — The rate at which beacon signals are transmitted from the wireless interface. The beacon signals allow wireless clients to maintain contact with the ADSL Router. They may also carry power-management information. (Range: 20-1000 TUs; Default: 100 TUs)◆Data Rate — The maximum data rate at which the wireless interface transmits multicast and broadcast packets. (Options: Auto, 1, 2, 5.5, 11, 6, 9, 18, 24, 36, 48, 54 Mbps; Default: Auto)
CHAPTER 7 | WLAN ConfigurationAdvanced Settings– 86 –◆Preamble Type — Sets the length of the signal preamble that is used at the start of a data transmission. (Default: Long)■Long Preamble: Sets the preamble to long (192 microseconds). Using a long preamble ensures the wireless interface can support all 802.11b and 802.11g clients.■Short Preamble: Sets the preamble according to the capability of clients that are currently asscociated. Uses a short preamble (96 microseconds) if all associated clients can support it, otherwise a long preamble is used. The wireless interface can increase data throughput when using a short preamble, but will only use a short preamble if it determines that all associated clients support it.◆Broadcast SSID — Enables/disables the wireless interface to broadcast an SSID (service set identifier) to uniquely identify it on the network.◆Apply Changes — Applies the specified changes.

CHAPTER 10 | Advanced ConfigurationRouting Configuration– 115 –ROUTING CONFIGURATIONThis page displays the information necessary to forward a packet along the best path toward its destination. Each packet contains information about its origin and destination. When a packet is received, a network device examines the packet and matches it to the routing table entry providing the best match for its destination. The table then provides the device with instructions for sending the packet to the next hop on its route across the network.Figure 68: Static RoutingThe following items are displayed on this pages:◆Enable — Enables static routing on the ADSL Router. (Default: Enabled)◆Destination — The network IP address of the subnet. The destination can be specified as the IP address of a subnet or a specific host in the subnet. It can also be specified as all zeros to indicate that this route should be used for all destinations for which no other route is defined.◆Subnet Mask — The network mask of the destination subnet. The default gateway uses a mask of 0.0.0.0.◆Next Hop — The IP address of the next hop through which traffic will flow towards the destination subnet.

The default value is 0, which means that the subnet is directly one hop away on the local LAN network. ◆Interface — The WAN interface to which a static routing subnet is to be applied. ◆Add Route — Adds a static route to the Static Route Table.◆Update — Clears the above fields.◆Delete Selected — Deletes the specified static route.STATIC ROUTE TABLEThis table displays all the configured static routes.◆Select — Highlights an entry in the Static Route Table.◆State — Displays if the route is enabled or disabled.◆Destination — Displays the final destination of the routed packets.◆Subnet Mask — Displays the subnet mask.◆Next Hop — The next hop that the packets will be routed to on their way to their final destination.◆Metric — Displays the number of hops from router to router that the packets must make before reaching their final destination.◆IF — Displays the interface the packets will be routed on.
CHAPTER 10 | Advanced ConfigurationRIP Configuration– 117 –RIP CONFIGURATIONRIP is an Internet protocol you can set up to share routing table information with other routing devices on your LAN, at your ISP’s location, or on remote networks connected to your network via the ADSL line. Most small home or office networks do not need to use RIP; they have only one router, such as the ADSL Router, and one path to an ISP. In these cases, there is no need to share routes, because all Internet data from the network is sent to the same ISP gateway. Figure 69: Dynamic RoutingThe following items are displayed on this pages:◆RIP — Enables or disables RIP on the unit. (Default: Disabled)RIP CONFIG TABLEThe RIP Config Table configures RIP related parameters on the unit.◆Interface — The name of the interface on which you want to enable RIP.

CHAPTER 10 | Advanced ConfigurationIP QoS– 118 –IP QOSThe QoS setting page is used to configure Quality of Service (QoS) for Traffic Prioritization and Bandwidth Management. Quality of Service (QoS) provides users the control over which type of outgoing data traffic is given priority by the router. The throughput rate of both the upload and download data passed through the ADSL Router can be throttled.The QoS is enforced by the QoS rules in the QoS table. A QoS rule contains two configuration blocks: Traffic Classification and Action. Figure 70: IP QoSThe following items are displayed on this pages:◆IP QoS — Enables IP QoS. (Default: Disabled)◆Default QoS — Specifies the type of QoS used. (Options: IP Pred, 802.1p; Default: IP Pred)SPECIFY TRAFFIC CLASSIFICATION RULESThe Traffic Classification enables you to classify packets on the basis of various fields in the packet and perhaps the physical ingress port. ◆Source/Destination IP — The source/destination IP address.

Using multicasting as opposed to sending the same data to the individual hosts uses less network bandwidth. The multicast feature also enables you to receive multicast video stream from multicast servers.IP hosts use Internet Group Management Protocol (IGMP) to report their multicast group memberships to neighboring routers. Similarly, multicast routers use IGMP to discover which of their hosts belong to multicast groups. This device supports IGMP proxy that handles IGMP messages. When enabled, this device acts as a proxy for a LAN host making requests to join and leave multicast groups, or a multicast router sending multicast packets to multicast group on the WAN side. Figure 71: IGMP ConfigurationThe following items are displayed on this pages:◆IGMP Proxy — Enables IGMP proxy. When enabled, the upstream interface acts as a host interface, sending query messages periodically to the downstream interfaces, sending join and leave messages to the upstream multicast router when a first join or last leave message is received from a downstream interface, and sending membership reports in response to query messages from the multicast router.◆Proxy Interface — Specifies the upstream WAN interface on which to implement IGMP proxy.NOTE: The IGMP Proxy feature is not supported in the current software release.
CHAPTER 10 | Advanced ConfigurationBridge Configuration– 121 –BRIDGE CONFIGURATIONThis feature allows you to set the bridge aging time and to enable Spanning Tree.The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to provide backup links between bridges. This allows a wireless bridge to interact with other bridging devices (that is, an STP-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.Figure 72: Bridge ConfigurationThe following items are displayed on this pages:◆Ageing Time — Sets the MAC address ageing time, in seconds. After the aging time has been reached with no traffic received, the unit will delete the address from the forwarding database. (Default: 300 seconds)◆802.1d Spanning Tree — Enables/disables the Spanning Tree Protocol on the ADSL Router. (Default: Disabled)
CHAPTER 10 | Advanced ConfigurationIP Passthrough– 122 –IP PASSTHROUGHIP Passthrough enables a host computer on the LAN to have direct access from the WAN with a real public IP address. When IP Passthrough is enabled, all IP traffic is forwarded to the host computer. This can be needed with some software applications that do not function reliably when using Network Address Translation.Figure 73: IP PassthroughThe following items are displayed on this pages:◆IP Passthrough — Enables IP PassThrough for a host computer on the LAN. When configured, the local host computer will share the public IP settings with the WAN interface of the router.◆Lease Time — Specifies a lease time for the IP Passthrough host.

– 139 –CCABLES AND PINOUTSTWISTED-PAIR CABLE ASSIGNMENTSFor 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. NOTE: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.CAUTION: DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.The following figure illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.Figure 81: RJ-45 Connector8118
APPENDIX C | Cables and Pinouts10/100BASE-TX Pin Assignments– 140 –10/100BASE-TX PIN ASSIGNMENTSUse unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).The RJ-45 port on the access point supports automatic MDI/MDI-X operation, so you can use straight-through or crossover cables for all network connections to PCs, switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. STRAIGHT-THROUGH WIRINGIf the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type.)You must connect all four wire pairs as shown in the following diagram to support Gigabit Ethernet connections.Table 4: 10/100BASE-TX MDI and MDI-X Port PinoutsPIN MDI Signal Nameaa.

APPENDIX C | Cables and PinoutsRJ-11 Ports– 142 –RJ-11 PORTSStandard telephone RJ-11 connectors and cabling can be found in several common wiring patterns. These six-pin connectors can accommodate up to three wire-pairs (three telephone lines), but usually only one or two pairs of conductor pins and wires are implemented.The RJ-11 ports on the side of the Gateway contain two wire-pairs, an inner pair (pins 3 and 4) and outer pair (pins 2 and 5). On the LINE port, the inner wire-pair carries both voice and digital data. On the PHONE port, the inner wire-pair carries voice only.The outer wire-pair is only connected if there is a second telephone line, and carries voice only.Figure 84: RJ-11 Wire Pairs Table 5: RJ-11 Port PinoutsPin Signal Name Wire Color1Not used2 Line 2 Tip Black or White/Orange3 Line 1 Ring Red or Blue/White4 Line 1 Tip Green or White/Blue5 Line 2 Ring Yellow or Orange/White6Not used123456Blue/WhiteWhite/BlueR1 T1123456RedGreenR1 T1 R2T2BlackYellow123456Blue/WhiteWhite/BlueR1 T1 R2T2White/OrangeOrange/White6x2 Jack 6x4 Jack6x4 JackT = Tip R = Ring
