2 Overview 2.1 Introduction Watson SHDSL router is an innovative Next-Generation DSL solution designed for enabling high-speed Internet or point-to-point connectivity to business customers. Watson SHDSL router uses Ethernet in the First Mile (EFM) technology, which is a transparent extension of Ethernet-base LANs into wide area networks. No conversion of packet formats is required when transiting between LAN and WAN.
Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 Several Watson Ethernet plug-in cards (SZ.866.V654) are installed in a subrack at the central office or the point of presence. Depending on the service offered each plug-in can serve between one and four customers. At the customer premises a Watson SHDSL router is installed. Traffic from each customer is available at a dedicated Ethernet interface in the central office.

Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 2.4.4 SHDSL Modem The SHDSL modem is responsible for transporting the Ethernet packets over the DSL wire pairs. The Packet Transport Mode (PTM TPS-TC layer) of the SHDSL ETSI TS 101 524 / ITU-T G.991.2 standards is used for this purpose. The modem supports the following two standardized packet mode encapsulation: HDLC and IEEE EFM 64b/65b framing.
3 Features 3.1 Network connections Watson SHDSL router supports various network connections. Besides the physical LAN and WAN connections, other logical connections, using tunneling protocols over existing connections, such as PPP and VPN can be configured. Every network connection in Watson SHDSL router can be configured as one of three types: WAN, LAN or DMZ. This provides high flexibility and increased functionality. For example a network connection can be defined as a DMZ (Demilitarized) network.
Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 3.1.3 Dynamic Host Configuration Protocol (DHCP) Watson SHDSL router’s WAN connection can be configured to act as a DHCP client. The server that assigns the router with an IP address also assigns a subnet mask that can be overridden if necessary. Watson SHDSL router’s Dynamic Host Configuration Protocol (DHCP) server makes it possible to easily add computers that are configured as DHCP clients to the local network.
Watson-SHDSL-Router-Manual.doc Version 1.1-07 Watson SHDSL Router Operating Manual Watson SHDSL router’s Point-to-Point Protocol (PPP) currently supports four authentication protocols: Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), and Microsoft CHAP version 1 and 2. PPP supports encryption facilities to secure the data across the network connection.
Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 3.2 Security The firewall supports advanced filtering, designed to allow comprehensive control over the firewall's behavior. Additional features, including surfing restrictions and access control, can also be easily configured locally by the user through a userfriendly Web-based interface, or remotely by a service provider. 3.2.
Watson-SHDSL-Router-Manual.doc Version 1.1-07 Watson SHDSL Router Operating Manual additional public IP addresses to port forwarding rules, and enter into the 'NAT IP Addresses Pool'. You will then be able to define FTP to use address X to reach computer A and address Y to reach computer B. Additionally, port forwarding enables you to redirect traffic to a different port instead of the one to which it was designated.
Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 port triggering since the outbound traffic triggers to which ports inbound traffic is directed. For example, consider a server that is accessed using UDP protocol on port 2222. The server responds by connecting the user using UDP on port 3333 when starting sessions.
Watson-SHDSL-Router-Manual.doc Version 1.1-07 Watson SHDSL Router Operating Manual 3.2.8 Security Log The Security Log displays a list of firewall-related events, including attempts to establish inbound and outbound connections, attempts to authenticate through an administrative interface (Web-based management or Telnet terminal), firewall configuration and system start-up.. 3.3 VLAN Watson SHDSL router supports VLAN functions according to IEEE 802.1q. 3.3.
Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 group containing up to 4,094 customer VLANs. This allows a service provider to provide different service, based on specific VLANs, for many different customers. A service provider's customer may require a range of VLANs to handle multiple applications. A service provider's customer can assign his own inner VLAN tags on ports for these applications. The service provider can assign an outer VLAN tag for each customer.
Watson-SHDSL-Router-Manual.doc Version 1.1-07 Watson SHDSL Router Operating Manual 3.4.1 Traffic Priority Traffic Priority allows managing and avoiding traffic congestion by defining inbound and outbound priority rules. These rules determine the priority that packets, traveling through the router, will receive. QoS parameters (DSCP marking and packet priority) are set per packet, on an application basis.
Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 DiffServ defines a field in IP packet headers referred to as DSCP. Hosts or routers passing traffic to a DiffServ-enabled network will typically mark each transmitted packet with an appropriate DSCP. The DSCP markings are used by DiffServ network routers to appropriately classify packets and to apply particular queue handling or scheduling behavior.
Watson-SHDSL-Router-Manual.doc Version 1.1-07 Watson SHDSL Router Operating Manual 3.5 DSL 3.5.1 Linerates and DSL sync rates Watson EFM Plug-in modems support symmetrical DSL transmission as specified in ETSI TS 101 524 (SDSL) and ITU-T G.991.2 Annex B/G (G.SHDSL.bis). The linecode used is either TC-PAM 16 or TC-PAM 32. With TC-PAM 16 the supported linerate rates per pair are from 192 kbit/s to 3’840 kbit/s (3 - 60 timeslots of 64 kbit/s).
Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 The SHDSL M-pair mode is used for backwards compatibility reason when Watson SHDSL router is connected to Watson Ethernet plug-in (SZ.866.V654) as showed in Figure 2-1. In this mode each wire pair of Watson SHDSL router must be configured with the same linerate. If one pair fails then the entire link must be restarted. A multi-pair DSL link is called a span. Watson SHDSL router has only one span.

Watson SHDSL Router Operating Manual Watson-SHDSL-Router-Manual.doc Version 1.1-07 3.5.4 Power Backoff The transmit power of the modem can be decreased by activating the power back-off mode. This reduces interference to other transmission systems operating on adjacent pairs bundled in the same cable.
Watson-SHDSL-Router-Manual.doc Version 1.1-07 Watson SHDSL Router Operating Manual 3.5.6 Master / Slave To start up a DSL link, one system unit must be configured as master modem (STU-C) and the other one as slave (STU-R). The master controls the link startup procedure. If both system units are configured as master or as slave, no startup will occur. Usually, the Watson Ethernet plug-in is configured as master and the Watson SHDSL router as slave (default setting).
