Page 19: Overview
SHDSL uses Trellis-coded PAM-16 and PAM-32 linecodes supporting multiple li- nerates as well as 1-pair, 2-pair and 4-pair DSL transmission. The Watson Ethernet modems are available as plug-in cards and as tabletop units. Both plug-in cards and tabletops can work as DSL master modems (STU- C) and as DSL slave modems (STU-R).
Page 20: Figure 2-2: Campus Networks

Page 30: Ethernet Bridging
Operating Manual Version 3.3-01 3.2.2 Ethernet Bridging The Watson Ethernet plug-in card has a built-in Ethernet bridge that connects Ethernet ports, DSL spans and the plug-in controller: Figure 3-4: Watson Ethernet plug-in Block diagram The Ethernet bridge supports the following modes 1) VLAN bridging.
Page 31: Mac Defect Signaling
Figure 3-6 below shows a simple VLAN configuration example. Both on the DSL and on the Ethernet side untagged packets are used. On the Watson Ethernet plug-in four VLANs (VLAN 1, VLAN 2, VLAN 3 and VLAN 4) are configured. De- pending on its ingress port each packet gets a default tag between 1 and 4.
Page 32: Figure 3-6: Simple Vlan Example
Ethernet trunk interface. On the DSL lines untagged packets are used. Upon in- gress into the Watson Ethernet plug-in the packets get a default VLAN tag be- tween 1 and 4 based on their ingress port. All traffic is switched to port ETH1 which is member of all four VLANs.
Page 33: Individual And Shared Forwarding Databases
Individual and shared forwarding databases VLANs can have individual or shared forwarding databases (IVL or SVL opera- tion). The Watson Ethernet plug-in supports 16 separate forwarding databases which can be freely assigned to VLANs. Address learning is always done based on MAC addresses without taking VIDs into account.
Page 34: Figure 3-9: Individual Vlan Learning (Ivl) Example
Watson Ethernet Watson-Ethernet-Manual.doc Operating Manual Version 3.3-01 Figure 3-9: Individual VLAN learning (IVL) example For IVL operation each VLAN must be configured to use an own forwarding da- tabase. This is done by specifying individual forwarding database identifiers (FIDs) per VLAN in the VLANCREATE Monitor command.
Page 35: Stacked Vlans
Version 3.3-01 Operating Manual  Notes: The Watson Ethernet tabletop modems are transparent to VLANs, i.e. VLAN tags are preserved during transmission over the DSL.  The Watson Ethernet tabletop modem has a single address learning data- base which does not take VIDs into account.
Page 36: Class Of Service (Cos)
Figure 3-12: Class of Service functions When a packet enters the Watson Ethernet plug-in its priority is be classified ei- ther by layer 2 information (IEEE 802.1p bits in the VLAN tag) or by layer 3 in- formation (DSCP in the IP header). The packet is then associated with one of the priority levels.

Only the entire port after scheduling can be rate limited, there are no individual queues at this stage. Note: CoS functions are not available on the Watson Ethernet tabletop modems. 3.2.9 Spanning Tree Protocol The Watson Ethernet plug-in modems support the Rapid Spanning Tree (RSTP) protocol according to IEEE 802.1D-2004.
Page 39 Watson-Ethernet-Manual.doc Watson Ethernet Version 3.3-01 Operating Manual The spanning tree network protocol provides a loop free topology for any bridged LAN. It detects/disables network loops and provides backup links between bridges. If a loop is detected then the protocol blocks one or more redundant ports.
Page 40: Table 3-6: Recommended Port Cost Values
Watson Ethernet Watson-Ethernet-Manual.doc Operating Manual Version 3.3-01  Root port determination: each non-root bridge designates one root port. The root port is the port through which this non-root bridge communicates with the root bridge. The root port is the port on the non-root bridge with the lowest path cost (measured as sum the costs of all paths traversed to the root) to the root bridge.

Page 110: Mib Reference
The management information of the Watson Ethernet plug-in is modeled accord- ing to standardized MIBs. Additionally two vendor-specific MIBs are supported: the Schmid HDSL MIB to control the Watson Ethernet tabletop modems and the Schmid MIB which contains a unique hardware identifier for the modems.
Page 111: Entity Mib (Rfc 2737)
8.2.6 IF MIB (RFC 2863) The Interfaces MIB contains a table of all interfaces of the Watson Ethernet plug- in card and the hierarchical relations between them. Note that the Ethernet inter- faces of the Watson Ethernet tabletop modems are not visible in the ifTable.
