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.

vii

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.

viii

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.

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 120 OVERVIEW

This manual covers the use of the following products:

• TSU 120

• TSU 120e

Unless otherwise stated, the TSU 120 refers to both products.

The TSU 120 is a T1/FT1 multiplexer with an Nx56/64 V.35 data port, a DSX-1 (PBX) interface, one option slot, and embedded SNMP management. The TSU 120e offers a built-in dial back up feature for the Nx port. The TSU 120’s option slot accepts one of many available option modules for voice and data applications.

The TSU 120 links 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 120 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

Chapter 1. Introduction

The TSU 120 offers a wide variety of network management options. You can manage via SNMP through the 10BaseT (TSU 120e only) or chain-in ports. If you are using T-WATCH Pro, a Microsoft Windows® -based program, you can manage the TSU 120 via the same 10BaseT (TSU 120e only) or chain-in ports. An enhanced VT 100 terminal interface is also provided.

Standard Features in the TSU 120

The following list describes the standard features in both the TSU 120 and the enhanced TSU 120e.

• A single T1 interface.

• An Nx56/64 V.35 port and DSX-1 (PBX) interface.

• SNMP, Telnet, and T-WATCH Pro management via SLIP or 10BaseT (10BaseT is only in the TSU 120e).

• Ability to proxy for “agentless” units

• Enhanced terminal mode

• 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.

• Data drop and insert, as well as full drop and insert.

• Flash memory for software updates.

• Timing is selectable from the network, from the Nx56/64 or DSX-1 ports, internally, or from a secondary interface.

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

• QRSS; 511 test patterns using Nx option.

• Integrated Dial Backup Capability in the Base Nx56/64 port ( TSU 120e only)

• Extensive self-testing and monitoring provides assurance of proper operation.

The base Nx54/64 provides a V.35 interface to a router. The PBX is interfaced to the TSU 120 with the base DSX-1 interface. An OCU DP module and OCU DP plug-on board provide two Switched-56 circuits for video conferencing. The 10BaseT port allows SNMP network management over the LAN (TSU 120e only). See
