The Ericsson W20e, W21 and W25 support 1.8 and 3V SIM while the Ericsson W20a only supports 3V SIM. 2.3 Wireless LAN (WLAN) Interface The W2x terminals act as wireless Access Point (AP) supporting IEEE 802.11b/g standards. IEEE 802.11b operates in the unlicensed 2.4 GHz band and can theoretically achieve 11 Mb/s. Practical throughput, ranges from ~7 Mb/s (using UDP) to ~6 Mb/s (using TCP). IEEE 802.11g operates in the same band as 802.11b and has a theoretical top speed of 54 Mb/s.
2.4 USB Interface The W2x terminals include a USB 2.0 Host Controller with two (2) ports (type A) supporting both full speed and high-speed. The USB interface supports one low power device per port hence the maximum power consumption of a device is 100 mA. Maximum practical cable length for USB is 5 m. 2.5 Ethernet Interface The W2x terminals include an Ethernet switch with four (4) external LAN 4x10/100BaseTx ports (female RJ45) for connection to PC equipment.

3 Data Features and Function 3.1 Layer 2 Functions 3.1.1 Bridging LAN and WLAN The W2x terminals support bridging/switching traffic between the LAN and WLAN interfaces. 3.1.2 WLAN Whitelist The W2x terminals support WLAN whitelist, also known as “MAC Association Control” or “MAC Access List”. Up to 20 WLAN MAC addresses can be added to the list and the use of the whitelist is possible to enable/disable. 3.
3.2.5.1 NAT Port Forwarding The NAT Port Forwarding feature, sometimes referred to as Virtual Server, redirects traffic from the WAN side to a server on the LAN side. The Port Forwarding feature requires a public WAN IP address on the W2x terminals. 3.2.5.2 NAT ALGs An ALG enables the transfer of specific application streams through firewall policies and NAT.
It is possible to have two storage devices or a storage device and a printer connected to the W2x terminal at the same time. When an external hub is connected, the W2x terminals support connection of up to two storage devices and one printer at the same time. Both USB 1.1 and 2.0 (full speed and high-speed) are supported. 3.4 Authentication Authentication towards the UMTS/GSM radio network can be done via either PIN code or PPP username and password.
4 Telephony Features (W25 only) The Ericsson W25 provides analogue voice services via the telephony line interface with high speech quality. 4.1 Line Interface The POTS (FxS) interface can be configured, i.e. impedance, frequency, cadence, levels etc. DTMF dialing is supported. 4.1.1 Ringing Signal It is possible to configure different ringing signals depending on the call type. The mapping and ring frequency are also configurable. 4.1.
• • • • • • • 4.3 Call Hold Multi Party Service Barring of All Outgoing Calls Barring of Outgoing International Calls Barring of Outgoing Internal Calls except those directed to the Home PLMN Country Barring of All Incoming Calls Barring of Incoming Calls when Roaming Outside the Home PLMN Country. Dial Process The Ericsson W25 supports E.164 numbering. There are three ways to indicate that the dialed number sequence is complete: • • • Dialing the EON key (e.g. # or *) immediately sends the call.
4.4 DTMF Transmission The Ericsson W25 is capable of transmitting DTMF on the radio interface as received on the 2W-line interface using message based signaling. It is possible to switch of the DTMF message based signaling so that DTMF tones go through the voice code. The Ericsson W25 supports DTMF digits 0-9 and A&B. 4.5 Emergency Calls Emergency calls (i.e. 112 or 911) can always be made, even without a SIM card or the correct PIN code.
5 Fax Support (W25 only) To enable Fax support the Ericsson W25 uses the Voice over IP (VoIP) protocol called SIP. The Ericsson W25 works as a fax gateway between the POTS interface and the IP network using the T.38 protocol. The fax machine is connected to one of the two POTS interfaces on the Ericsson W25, which is dedicated for a fax machine. Connected to this fax port is a SIP user agent, which manages and controls the media streams by using the SIP protocol towards the SIP server and media Gateway.
6 Wireless LAN (WLAN) 6.1 SSIDs The W2x terminals support single SSID. This SSID and a unique MAC address are broadcasted in the beacon at regular intervals. The SSID name can be set (changed) with a maximum length of 32 alphanumeric characters. It is also possible to configure the SSID to be hidden. The SSID can be either “open” (no authentication or encryption) or “closed” (meaning either WEP or WPA security). See below for security details. 6.
7 Configuration and Management 7.1 Web User Interface The end-user configures the W2x terminals through a web user interface (WUI) that is accessible through the LAN and WLAN interfaces. The WUI also includes a Configuration Wizard for easy setup of the local Internet connection and wireless network. 7.2 Command Line Interface The CLI is mainly intended for operator service personnel handling tasks like storing/exchanging configuration files and for maintenance purpose (i.e.
7.4 Management Tools 7.4.1 Software Update The W2x terminals run Linux OS on an Intel hardware platform. The flash file system is formatted as two partitions, each capable of holding a complete software image. If a software update process should get interrupted, e.g. power failure during the update process, there is always a last known good firmware image to boot from. 7.4.1.1 Manual Software Update Manual software updates is supported from FTP or HTTP(S) servers.
Events that generate an alarm are such that make it impossible to send or receive data, e.g. SIM card missing. 7.4.3.1 Interface Status and Statistics The following status/statistics information can be displayed from the WUI as well as from the CLI: WAN interface The mobile network (UMTS or GSM) signal quality. (*) Link status: up/down The protocol/mode used for the connection. The mobile network currently used for the connection (HSDPA, UMTS, GPRS, EDGE). Name of the mobile network operator.
8 Security The basic security feature of the W2x terminals are the same as any GSM phone, using a PIN code that comes with the subscription SIM card. The PIN code is simply entered via the WUI. To simplify usage, the W2x terminals have an auto PIN feature that requires the PIN code only to be entered the first time the unit is used or upon changing the SIM card.
9 Regulatory Approvals The W2x terminals are certified with EU Directives for the CE mark, Safety approvals, EMC and Radio Spectrum approvals and RF Exposure approvals for the following markets: • • • • • • • • 9.1 EU USA Canada Australia New Zealand Malaysia South Africa Singapore. RoHS Directive The W2x terminals meet the requirements of the RoHS directive. 9.2 WEEE Marking The W2x terminals meet the requirements in the WEEE directive and are marked accordingly. 9.
