Patton Electronics warrants all Model 1088 components to be
free from defects, and will—at our option—repair or replace the prod­uct should it fail within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials,
and does not cover customer damage, abuse or unauthorized modifi­cation. If this product fails or does not perform as warranted, your sole
recourse shall be repair or replacement as described above. Under no
condition shall Patton Electronics be liable for any damages incurred
by the use of this product. These damages include, but are not limited
to, the following: lost profits, lost savings and incidental or consequen­tial damages arising from the use of or inability to use this product.
Patton Electronics specifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall
be deemed an acceptance of these terms by the user.

1.1 RADIO AND TV INTERFERENCE

The Model 1088 generates and uses radio frequency energy, and
if not installed and used properly—that is, in strict accordance with the
manufacturer's instructions—may cause interference to radio and tele­vision reception. The Model 1088 has been tested and found to com­ply with the limits for a Class A computing device in accordance with
the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that interfer­ence will not occur in a particular installation. If the Model 1088 does
cause interference to radio or television reception, which can be deter­mined by disconnecting the unit, the user is encouraged to try to cor­rect the interference by one or more of the following measures: mov­ing the computing equipment away from the receiver, re-orienting the
receiving antenna and/or plugging the receiving equipment into a dif­ferent AC outlet (such that the computing equipment and receiver are
on different branches).

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the European Union
(EU). A Certificate of Compliance is available by contacting Technical
Support.

2.2 DESCRIPTION

The NetLink

TM

10BaseT mDSL Rocket (Model 1088) is a Multi-

Rate DSL Modem that provides seamless MAC Layer connectivity
between 2 peered 10BaseT LANs. Now, Enterprise users no longer
need to hassle with a bridge and a CSU/DSU or recurring leased line
costs. The NetLink Rocket allows users to add additional nodes to a
LAN that has reached its maximum distance limits or separate high
traffic areas of a LAN. The Rocket connects peered LANs and auto­matically forwards and receives LAN broadcasts, multi-casts and
frames across a 2-Wire DSL span. The 1088/I supports PPP (RFC

1661) and BCP (RFC 1638).

The

NetLink

TM

mDSL 10BaseT Rocket features include loop-

back diagnostics, inband SNMP/HTTP remote management capabili­ties using NetLink Plug-and-Play and externally accessible configura­tion switches. As a symmetric DSL modem, the NetLink

TM

mDSL

Rocket offers the same data rates in both directions over a single pair

of regular telephone lines using Carrierless Amplitude and Phase
(CAP) modulation. The Rocket connects to the DSL line via an RJ-45
jack. Standard power options include 115VAC, 230VAC, Universal
(115/230VAC) and any DC input between 36-60VDC.

3.0 PPP OPERATIONAL BACKGROUND

PPP is a protocol used for multi-plexed transport over a point­to-point link. PPP operates on all full duplex media, and is a sym­metric peer-to-peer protocol, which can be broken into three main
components: 1. A standard method to encapsulate datagrams
over serial links; 2. ALink Control Protocol (LCP) to establish, con­figure, and test the data-link connection; 3. A family of Network
Control Protocols (NCPs) to establish and configure different net­work layer protocols.

In order to establish communications over a point-to-point link,
each end of the PPP link must first announce its capabilities and
agree on the parameters of the link’s operation. This exchange is
facilitated through LCP Configure-Request packets.

Once the link has been established and optional facilities have
been negotiated, PPP will attempt to establish a network protocol.
PPP will use Network Control Protocol (NCP) to choose and con­figure one or more network layer protocols. Once each of the net­work layer protocols have been configured, datagrams from the
established network layer protocol can be sent over the link. The
link will remain configured for these communications until explicit
LCP or NCP packets close the link down, or until some external
event occurs.

The PPP Bridging Control Protocol (BCP), defined in RFC
1638, configures and enables/disables the bridge protocol on
both ends of the point-to-point link. BCP uses the same
packet exchange mechanism as the Link Control Protocol
(LCP). BCP is a Network Control Protocol of PPP, bridge
packets may not be exchanged until PPP has reached the
network layer protocol phase.

3.1 Applications

In situations where a routed network requires connectivity
to a remote Ethernet network, the interface on a router can
be configured as a PPP IP Half Bridge. The serial line to the
remote bridge functions as a Virtual Ethernet interface, effec­tively extending the routers serial port connection to the
remote network. The bridge device sends bridge packets
(BPDU's) to the router's serial interface. The router will
receive the layer three address information and will forward
these packets based on its IP address.

Figure 1 shows a typical Cisco router with a serial interface
configured as a PPP Half Bridge. The router serial interface uses
a remote device that supports PPP bridging to function as a node
on the remote Ethernet network. The serial interface on the Cisco
will have an IP address on the same Ethernet subnet as the
bridge.

For example, the customer site is assigned the addresses

192.168.1.0/24 through 192.168.1.1/24. The address

192.168.1.1/24 is also the default gateway for the remote net­work. The above settings remove any routing/forwarding intel­ligence from the CPE. The associated Cisco configuration will
set serial interface (s0) to accommodate half bridging for the
above example.

Authentication is optional under PPP. In a point-to-point
leased-line link, incoming customer facilities are usually fixed
in nature, therefore authentication is generally not required. If
the foreign device requires authentication via PAP or CHAP,
the PPP software will respond with default Peer-ID consisting
of the units Ethernet MAC address and a password which
consists of the unit’s Ethernet MAC address.

Some networking systems do not define network numbers
in packets sent out over a network. If a packet does not have
a specific destination network number, a router will assume
that the packet is set up for the local segment and will not for­ward it to any other sub-network. However, in cases where
two devices need to communicate over the wide-area, bridg­ing can be used to transport non-routable protocols.

Figure 2 illustrates transparent bridging between two
routers over a serial interface (s0). Bridging will occur
between the two Ethernet Interfaces on Router A (e0 and e1)
and the two Ethernet Interfaces on Router B (e0 and e1).
