Hotwire 6310 ReachDSL v1 (MVL) Modem Overview

The Hotwire® 6310 ReachDSL™ version 1 (formerly MVL®) Modem is a component in
the Hotwire ReachDSL System and interoperates with the Hotwire 8310 MVL, or
Hotwire 8312/8314 ReachDSL Card in the DSLAM (Digital Subscriber Line Access
Multiplexer) system. This system pro vides hi gh-spe ed I nternet or corporat e LAN a ccess
over traditional twisted-pair copper telephone wiring.

The ReachDSL technology:

Utilizes an inline phone filter on the ReachDSL modem’s PHONE jack.



Operates over existing copper wire with existing telephone jacks.



Includes a second line pass-through from the ReachDSL modem’s LINE jack to



PHONE jack to accommodate an attached 2-line telephone.
Provides rate adaptive data rates to dynamically adapt and allocate bandwidth to



optimize applications.

1

In addition, the ReachDSL v1 technology:



Transforms a single copper pair into multiple virtual lines to support multiple
services simultaneous ly.



Supports simultaneous mult iple access of four ReachDSL v1 modems with up to
254 end-user systems sharing one common WAN interface.



Features HomeLink, which provides peer-to-peer communications, including print
and file sharing applications (see
page 10).

Phone Filter

Depending on the type of pho ne handset and the qual ity of the home or busi ness wiring,
a phone filter is recommended to minimize background noise during a phone
conversation. An internal phone filter is included with the Hotwire 6310 ReachDSL v1
Modem. If additional telephones are used on the same phone line as the ReachDSL
modem, install one phone filter on each telephone.

There are two Hotwire phone filters:



Hotwire 6035 Universal Phone Filter is designed for use with a tabletop phone.



Hotwire 6040 Universal Wall Jack Phone Filter is designed for use with a wall
phone.

To improve data transmission throughput and minimize background noise during a
telephone conversation, make sure that:



The Hotwire 6310 ReachDSL v1 Modem is always powered on, even when not in
use, and



A Hotwire phone filter is installed on every telephone on the same line as the
Hotwire 6310 ReachDSL v1 Modem (see

Phone Filter

on page 3).

HomeLink (for ReachDSL v1 Modems Only)

HomeLink is a feature that provides peer-to-peer communications for PCs attached to
different Hotwire 6310 ReachDSL v1 modems at the customer premises.

For example, PCs that are not connected to the same physical Ethernet LAN can now
take advantage of the resources of the primary office computer. With the Microsoft
Windows operating system, multiple end-user systems can share resources, including:



File sharing



Print sharing



Secondary computer backup

To enable the sharing of resources and review security considerations, see Microsoft’s
Web site at

www.microsoft.com

In this example of HomeLink, the PC in the family room could use the office printer.

Increasing the Number of End-User Systems

A single end-user system is attached to the Hotwire 6310 ReachDSL v1 Modem by
using an Ethernet crossover cable. To increase the number of end-user systems,
connect all the PCs to an Ethernet hub using a straight-through cable.

On one line, the ReachDSL v1 system provides the capability to use up to four Hotwire
6310 ReachDSL v1 modems and 32 end-user systems in any combination.

Government Requirements

Certain governments require that instructions pertaining to connection to the telephone
network be i ncluded in the installation and operation manual. S pecific in structions are
listed in the following sections.

United States – Notice to Users of the Telephone Networ k

This equipment comp lies with P art 68 of the FCC rules . On th e equi pment is a label

1.

that contains, among other information, the FCC registration number and Ringer
Equivalence Number (REN) for this equipment. The label is located on the bottom
of your modem.

The Hotwire 6310 ReachDSL v1 Modem connects to the Public Switched

2.

Telephone Network (PSTN) using the Universal Service Order Code (USOC)
RJ11C or RJ14C.

The REN is used to determine the quantity of devices which may be connected to

3.

the telephone line. Excessive RENs on the t ele pho ne line may result in the devices
not ringing in response to an incoming ca ll. In most, b ut not al l areas, the sum of the
RENs should no t exceed five (5.0). To be certain of the number of de vi ces that may
be connected to the line, as determined by the total RENs, contact the telephone
company to determine the maximum RENs for the calling area.

If the modem causes harm to the telephone network, the telephone company will

4.

notify you in advance that temporary discontinuance of service may be required.
But if advance notice is not practical, the telephone company will notify the
customer as soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it is necessary.

The telephone company may make changes in its facilities, equipment, operations,

5.

or procedures that could affect the operation of the equipment. If this happens, the
telephone company will provide advance notice in order for you to make the
necessary modifications in order to maintain uninterrupted service.

If you experience trouble with this equipment, please contact your sales or service

6.

representative (as appropriate) for repair or warranty information. If the product
needs to be returned to th e com pan y service cent er for repair, conta ct them direc tly
for return instructions using one of the following methods:

Telephone:

to speak with a company representative.

If the trouble is causing harm to the telephone network, the telephone company
may request that you remove the equipment from the network until the problem is
resolved.

The user is not authorized to repair or modify the equipment.

Notice to Users of the Canadian Telephone Network

The Industry Canada label identifies certified equipment. This certification means that
the equipment meets telecommunications network protective, operational and safety
requirements as prescribed in the appropriate Terminal Equipment Technical
Requirements document(s). The Department does not guarantee the equipment will
operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment
must also be installed using an acceptable method of connection. The customer should
be aware that compliance with the above conditions may not prevent degradation of
service in some situations.

Repairs to certified e qui pm ent s hou ld be c oord inated by a representative designated by
the supplier . An y repai rs or alter ations m ade b y the user to this equ ipment, o r equipmen t
malfunctions, may give the telecommunications company cause to request to
disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of
the power utility, telephone lines and internal metallic water pipe system, if present, are
connected together. This precaution may be particularly important in rural areas.

CAUTION:

Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or electrician, as
appropriate.
