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.

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 600 OVERVIEW

This manual covers the use of the following products:

• TSU 600

• TSU 600 with DC power

• TSU 600e

• TSU 600e with DC power

Unless otherwise stated, the TSU 600 refers to all four products.

Product Description

The TSU 600 is a T1/FT1 multiplexer with six option slots and embed-

ded SNMP management. The TSU 600’s six option slots accept one of

many available option modules for voice and data applications. Each

module offers up to four ports for a total of 24 possible voice or data

ports.

The TSU 600 serves as the link between user data sources such as:

• local area network (LAN) bridges

•routers,

•computers,

• CAD systems,

• teleconferencing equipment, and

•PBXs.

Introduction

Through the use of multiple data ports, the TSU 600 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 change automati-

cally at predetermined times to use the available bandwidth most ad-

vantageously.

61202076L1-1 TSU 600 User Manual 1-1

Chapter 1. Introduction

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.

The TSU 600 offers a wide variety of network management options. You can manage via SNMP through the 10BaseT (600e only) or chain-in ports. If you are using T-Watch PRO, a Microsoft Windows® program, you can manage the TSU 600 via the same 10BaseT (600e only) or chainin ports. An enhanced VT-100 terminal interface is also provided.

Standard Features in the TSU 600

The standard features of the TSU 600 are listed below:

•A single T1 interface

• Six slots to house option modules with up to four additional data

ports, including voice

• Architecture that 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

• SNMP, Telnet, and T-Watch PRO management via SLIP or 10BaseT

(600e only)

• Ability to proxy for “agentless” units

• Enhanced terminal mode

• Support for a redundant AC power supply (600e only)

• 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 selectable from the network, from the slot 1 data port, inter-

nally, or from a secondary interface

• 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 to ensure proper operation

Chapter 2. Installation

Power Connection

The AC- powered TSU 600 is equipped with a captive, 8-foot power cord, terminated by a 3-prong plug which connects to a grounded power receptacle.

Power to the TSU 600 must be from a grounded 90-120 VAC, 50/ 60Hz source.

DC Powered Units

The DC-powered TSU 600 (1202076L1#DC or 1202076L2#DC) is equipped with a terminal strip on the rear of the unit. The power source should be connected to the terminal strip according to the polarity markings on the unit.

Example: A -48V source would be connected with the -48V return attached to the

(+) terminal and the -48VDC attached to the (-) terminal. Power must be from a DC source in the range of 21 to 26 VDC or in the range of 40 to 56VDC.

The protective cover should be reinstalled over the terminal strip once the power source is connected.

The DC-powered TSU 600 is to be installed only in restricted areas (dedicated equipment rooms, equipment closets, etc.) in accordance with Articles 110-16 and 110-18 of the National Electric Code, ANSI/NFPA 70.

Backup Power Supply (600e only)

The TSU 600e has two power supply slots on the right side of the chassis. The base unit is shipped with a single power supply. The TSU 600e is fully operational with only a single power supply, which may be installed on either the left (power supply A) or the right (power supply B). You can install a backup supply in the unused slot. The red System Alarm LED on the front panel will indicate failure of either supply.

61202076L1-1 TSU 600 User Manual 2-11

Chapter 2. Installation

The full self-test procedure (invoked from the front panel or T-Watch PRO) consists of the following tests:

Board level tests

Each of the TSU 600 boards contains an on-board processor which executes a series of tests checking the circuitry on the board.

• RAM and EPROM tests

• Verify on-board circuitry

Unit level tests

• Front panel LED verification

• Board-to-board interface test A test pattern is sent from the controller through a loopback on all other

boards and checked on the controller. This verifies the data path, clocks, and control signals for the entire chassis.

Initialization

Set User Passcode

The TSU 600 is designed to operate with or without the use of a passcode. The default condition is without a passcode.

If the unit is to be remotely accessed using T-Watch PRO, you must enter a passcode. When managing a number of units, the passcode can be the same for all the units.

The passcode should be a number easily remembered. Once entered, the passcode is required to access any operation other than viewing. See Set Passcode on page 6-2.

Set Unit Identification

The Unit ID sets the unit to respond to remote control (controlled by a device other than the front panel or terminal). If no Unit ID is recorded it is not possible to operate from any remote control device, including the local PC for T-Watch PRO or SNMP. See Unit ID on page 6-3 for details.

2-12 TSU 600 User Manual 61202076L1-1

Chapter 2. Installation

Set Control Port

The TSU 600 can be configured from the control port when T-Watch PRO, SNMP, or the terminal interface is being used.

If the control port is to be used, the control port baud rate must also be selected.

Chain-In (PC)

The unit can be controlled from an external PC connected directly or via modem to the Chain-In port. When using Chain-In, the selection of the Control Port baud rate from 9600 (factory default), 1200, 2400, or 4800, 19200, or 38400 must be made using the Unit Configuration menu. Unless locked out externally, the front panel can also control the unit.

Chain In/Chain Out

TSU 600 units and other TSUs can be linked together to form a chain. Figure 2-4 provides an example of a chain-in arrangement with a PC or a modem. The first TSU 600 in the chain receives controlling input from the PC or modem.

Subsequent TSUs in the chain are in a position to intake information from another TSU. This in-taking of information from another TSU in the chain is identified as Chain-In. The baud rate for the chained units must match that of the first unit.

Unless locked out externally, the front panel can also control the unit. At this point, the Unit Initialization procedure is concluded. If the unit

is to be configured remotely, there are no additional items necessary to complete prior to executing remote configuration.

Chapter 2. Installation

The Passcode, the Unit ID, and the Control Port settings are stored in a nonvolatile memory. This ensures that they are operable for subsequent power-up sequences.

Normal Power-Up Procedure

After the unit has been put into operation with the initial power-up and initialization, subsequent power-up procedure includes only the PowerUp Self-Test followed by the request for a passcode (password) if this option was selected during initialization.

Use the number keys to key in the previously recorded passcode and press Enter.

Alternate Methods of Control

T-Watch PRO (ADTRAN PC Program)

T-Watch PRO is the ADTRAN PC control program. It provides complete control over the configuration of the TSU 600 using a graphical interface and displays the same status and performance data as the front panel LCD. This data is displayed in the form of tables and graphs.

The T-Watch PRO program has the following capabilities:

• Interfaces with a modem which permits dialing into a remote TSU 600 location to configure the unit or read the status or performance of the unit.

• Receives traps from any TSU product.

• Records and creates display performance data over a 30 day period.

• Accesses units via the local area network.

TSU 600 Clock Sources

The TSU 600 is operable from various clock sources, permitting it to perform properly in many different applications. The network interface timing mode is set by using the Network (NI) Configuration menu options. The following options are available:

•Network Timing

•DTE Timing

•UBR1TE

• Internal Timing

•Secondary Timing

• Normal (CSU) Timing The selected clock option always designates the clock source for trans-

mission. Clocking necessary for receiving data is always recovered from incoming data.

Network Timing

The network is the source of timing. The received data clocking is looped back to the network, where it is used to determine the transmission timing. This option is also referred to as loop timed as the transmission clock is derived from the received clock. See Figure 5-2.

Loopback Tests

A number of different loopbacks can be invoked locally from the front panel, by T-Watch PRO commands, or remotely by using special inband codes (AT&T D4 network loop up and loop down codes). Additionally, the loopbacks can be remotely controlled by means of out-ofband commands by the T1 ESF FDL or from T-Watch PRO by a modem connection. See Figure 7-2.

Network Interface Loopbacks

Network interface loopbacks affect the entire T1 data stream. There are two types of network loopbacks: line loopback and payload loopback.

Line loopback loops all of the received data back toward the network. The transmitted data is the identical line code that was received, including any bipolar violations or framing errors.

Payload loopback is similar to line loopback, except that the framing is extracted from the received data and then regenerated for the transmitted data.

Run Self-Test

The self-test checks the integrity of the internal operation of the electronic components by performing memory tests and by sending and verifying data test patterns through all internal interfaces. Although actual user data cannot be passed during these tests, the self-test can be run with the network and DTE interfaces in place and will not disturb any external interface.

The memory portion of the self-test automatically executes upon powerup. A full self-test can be commanded from a front panel menu or from T-Watch PRO.

In addition to the specified self-tests, background tests are run on various parts of the internal electronics. These run during normal operation to confirm continued correct functioning.

This menu selection is used to execute a full internal self-test. The results of the self-tests are displayed in the LCD. Upon invoking the command, the LCD displays System Self-Test and the Test LEDs are illuminated. Test failures are displayed in the LCD window. The self-test consists of the following tests:

Board level tests

Chapter 7. Test Menu

Each of the TSU 600 boards contain an on- board processor which executes a series of tests checking the circuitry on the board.

• RAM tests; EPROM checksum

• DS0 map tests

• On-board data path; sending a known test pattern through an onboard loop

Unit level tests

• Front panel LED verification

• Phase Lock Loop verify

• Board-to-board interface test

A test pattern is sent from the controller through a loopback on all other boards and is checked on the controller. This verifies the data path, clocks, and control signals.

If a failure is detected, note the failure number and contact ADTRAN Technical Support.

The execution of self-test will disrupt normal data flow and prevent remote communication until the self-test is completed.

8-10 TSU 600 User Manual 61202076L1-1

Appendix A

As local area network (LAN) environments became standardized over the past ten years, multi-vendor equipment grew with competition. It became necessary to manage the various vendor equipment from a single control console. Thus, the SNMP emerged as the standard for managing commercial TCP/IP networks.

The term SNMP broadly refers to the message protocols used to exchange information between the network and the managed devices, as well as to the structure of network management databases.

Understanding SNMP

Basic Components

SNMP has three basic components: Network Manager, Agent, and MIB.

Network Manager

This is a control program that collects, controls, and presents data pertinent to the operation of the network devices. It resides on a network management station.

Agent

This is a control program that responds to queries and commands from the network manager and returns requested information or invokes configuration changes initiated by the manager. It resides in each network device.

61202076L1-1 TSU 600 User Manual A-1

Appendix A. Understanding SNMP

MIB

This is an index to the organized data within a network device. It defines the operating parameters that can be controlled or monitored. When requesting the network manager to retrieve or modify a particular piece of information about a network device, the network manager transmits the request to that network device. The agent in that device interprets the incoming request, performs the requested task, and sends its response to the network manager. The network manager collects all the data from the various network devices and presents it in a consistent form.

Commands

Using SNMP Version 1, the network manager can issue three types of commands: GetRequest, GetNextRequest, and SetRequest.

Command Description

GetRequest This command retrieves a single item or

GetNextRequest This command retrieves the next item in

the first in a series from a network device.

a series from a network device.

SetRequest This command writes information to a

network device.

Message

The network device issues two types of messages:

GetResponse and Trap.

Command Description

GetResponse This message is the response to a network man-

ager GetRequest or GetNextRequest command.

Tr a p This is an unsolicited message issued by a net-

work device to report an operational anomaly or an alarm condition to the network manager. These messages are typically encased within informational packets and transported over the LAN or WAN (wide area network).
