Federal Communications Commission Radio Frequency Interference
Statement

This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to Part 15 of the FCC Rules. These lim­its are designed to provide reasonable protection against harmful inter­ference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio frequencies. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.

Shielded cables must be used with this unit to ensure compliance
with Class A FCC limits.

Changes or modifications to this unit not expressly approved by
the party responsible for compliance could void the user’s author­ity to operate the equipment.

CANADIAN EMISSIONS REQUIREMENTS

This digital apparatus does not exceed the Class A limits for radio noise
emissions from digital apparatus as set out in the interference-causing
equipment standard entitled “Digital Apparatus,” ICES-003 of the De­partment of Communications.

Cet appareil nuerique respecte les limites de bruits radioelectriques ap­plicables aux appareils numeriques de Class A prescrites dans la norme
sur le materiel brouilleur: “Appareils Numeriques,” NMB-003 edictee
par le ministre des Communications.

CANADIAN EQUIPMENT LIMITATIONS

The Industry Canada Certification label identifies certified equip­ment. This certification means that the equipment meets certain
telecommunications network protective, operational, and safety
requirements. 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. In some cases, the company's inside wiring associated
with a single line individual service may be extended by means of a cer­tified connector assembly (telephone extension cord). The customer
should be aware that compliance with the above conditions may not pre­vent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Cana­dian maintenance facility designated by the supplier. Any repairs or al­terations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to re­quest the user 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
waterpipe system, if present, are connected together. This precaution
may be particularly important in rural areas.

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

The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop which is
used by the device, to prevent overloading. The termination on a loop
may consist of any combination of devices subject only to the equipment
that the total of the LNs of all devices does not exceed 100.

The ringer equivalence number (REN) assigned to each terminal adapter
is used to determine the total number of devices that may be connected
to each circuit. The sum of the RENs from all devices in the circuit should
not exceed a total of 5.0.

vii

AFFIDAVIT REQUIREMENTS FOR CONNECTION

TO DIGITAL SERVICES

• An affidavit is required to be given to the telephone company when­ever digital terminal equipment without encoded analog content
and billing protection is used to transmit digital signals containing
encoded analog content which are intended for eventual conversion
into voiceband analog signals and transmitted on the network.

• The affidavit shall affirm that either no encoded analog content or
billing information is being transmitted or that the output of the de­vice meets Part 68 encoded analog content or billing protection spec­ifications.

• End user/customer will be responsible to file an affidavit with the
local exchange carrier when connecting unprotected CPE to a 1.544
Mbps or subrate digital services.

• Until such time as subrate digital terminal equipment is registered
for voice applications, the affidavit requirement for subrate services
is waived.

TSU 100 OVERVIEW

This manual covers the use of the following products:

• TSU 100

• TSU 100e

Unless otherwise stated, the TSU 100 refers to both products.

The TSU 100 is a T1/FT1 multiplexer with an Nx56/64 V.35
data port, one option slot and embedded SNMP management.
The TSU 100e also offers a built-in dial back-up feature for the
Nx port. The TSU 100’s option slot accepts one of many avail­able option modules for voice and data applications.

The TSU 100 serves as the link between user data sources such
as local area network (LAN) bridges and routers, computers,
CAD systems, teleconferencing equipment, and PBXs. Through
the use of multiple data ports, the TSU 100 can simultaneously
connect one or more of these devices to a T1 circuit. The
amount of bandwidth allocated to each port is custom-pro­grammable. You can manually allocate bandwidth or set the
bandwidth to automatically change at predetermined times to
use the available bandwidth most advantageously. Changes in
the configuration do not disrupt data flow in channels that are
not being reconfigured. The unique architecture and the avail­ability of option modules provides a path for growth to accom­modate future requirements.

Introduction

61202052L1-1 TSU 100 User Manual 1-1

Chapter 1. Introduction

The TSU 100 offers a variety of network management options.
You can manage via SNMP through the 10BaseT
(TSU 100e only) or chain-in ports. If you are using T-WATCH
Pro, a Microsoft Windows® program, you can manage the
TSU 100 via the same 10BaseT (TSU 100e only) or chain-in
ports. An enhanced VT-100 terminal interface is also provided.

Standard Features in the TSU 100

The following list describes the standard features in the TSU

100.

• A single T1 interface

• A Nx/DBU V.35 port (DBU in TSU 100e only)

• An inband communication channel requiring only 8k of
bandwidth from a single DS0

• One option slot to house option modules with up to four ad­ditional ports, including voice and data

• Allows mix of port types to meet the data interface require­ments

• Easy configuration capabilities using simplistic menus dis­played in a liquid crystal display (LCD) window operated
by a front panel keypad

• Two programmable configuration maps that define the
bandwidth allocation between data ports

• Flash memory for software updates

• Selectable timing from the network, from the Nx56/64 port,
internally, or from a secondary interface

• SNMP, Telnet, and T-WATCH Pro management via SLIP or
10BaseT (TSU 100e only)

• Ability to proxy for agentless units

• Enhanced terminal mode

• QRSS; 511 test patterns using Nx option

• Fractional T1 loopbacks as defined in Annex B of ANSI
T1.403-1995

• Extensive self-testing and monitoring that ensures proper
operation
