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.

vi

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.

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.

viii

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.

Introduction

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.

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.

Network Interface

The Network Interface (NI) port provides the connection to the T1. This port complies with the applicable ANSI and AT&T standards. For more information see the Wiring section in

Appendix C, on page C-1.

Network Test Interface

The IN and OUT test jacks for the network interface provide intrusive test capability for the incoming T1. By connecting to these jacks with test equipment, the T1 connection will be broken, and the test equipment will terminate the incoming T1. The R-MON test jack provides a bridged access jack for nonintrusive monitoring of the incoming T1. When connected to this jack, the test equipment should be configured for a bridged termination.

Nx56/64 Serial Interface (TSU 120e only)

The Nx56/64 provides a serial V.35 port that operates from 56 kbps to 1.536 Mbps. This port provides 511 pattern generation and detection and remote loopback capability.

Power Up Testing

When shipped from the factory, the TSU 120 is set to factory default conditions. At the first application of power, the unit automatically executes a memory self-test. A full self-test can be run from the front panel. A passcode and Unit ID may be set using the UTIL MENU.

Self-Test

Upon a power-up, the LCD displays MEMORY TEST NOW TESTING and the Test LEDs are illuminated. When the self-test is completed with no failures detected, the OK LED lights up and the LCD momentarily displays MEMORY TEST(S) PASSED. If a failure is detected, a list of failures is displayed in the LCD window.

Initialization

Set User Passcode

The TSU 120 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 Change/Set a Passcode on page 6-4 for details.

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 6-4 for details.

Chapter 2. Installation

Set Chain Port Input

The TSU 120 can be configured from the chain port input when T-WATCH Pro, SNMP, or the terminal interface are being used. In this case, the chain 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 chainin, the selection of the chain-in port baud rate from 9600 (factory default), 1200, 2400, 19200, or 38400 must be made using the UNIT CONFIGURATION MENU. See Unit Menu on page 5-12 for details.

Unless locked out externally, the front panel can also control the unit.

Chain-in/Chain Out

TSU 120 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 120 in the chain receives controlling input from the PC or modem.

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.

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

Power-Up Procedure

After the unit has been put into operation with the initial power-up and initialization, the subsequent power-up procedure includes only the power-up self-test followed by the request for a passcode (password) if this option was selected during initialization. Use the Number Keys to enter the previously recorded passcode and press Enter.

Press Cancel as many times as needed to return to the desired menu level or press Shift+0 (Home) to return to the main menu.

Data Port Identification

When configuring the unit, menu selections will include options from data port submenus. Selecting data ports is necessary because the TSU 120 uses a slot-port method to identify which data port the menu item is referencing. If a module containing a PBX DSX-1 option card with an Nx56/64 plug-on interface is installed in the option slot, it would be designated as:

DSX-1 Passthru=1.1

Where slot=1 and port =1.

The DSX-1 is located in the option slot and is the first port in that slot.

Nx56/64=1.2

Where slot=1 and port=2.

The Nx is located in the slot and is the second port in that slot.

The ports that are built into the TSU 120 are referenced as Slot 0. The Nx56/64 would be designated as 0.1 and the DSX-1 would be referenced as 0.2.

DTE Timing

The DTE is the source of timing. The TSU 120 uses the incoming DTE clock to determine the transmission timing. This is typically used in applications where it is necessary to have the DTE as the primary clock source, (such as limited distance line drivers). See Figure 5-4.

Normal (CSU) Timing

In the Normal (CSU) Timing mode, the Receive Clock is derived from the Network Interface while the Transmit Clock is derived from the PBX or other alternative timing source, connected to the Secondary Interface (e.g., Drop and Insert or DSX-1). See Figure 5-7.

This timing option is the same as that typically used for CSUs. This is the preferred mode for use with a PBX application.

Figure 5-8. DS0 Map Designations

Map A and Map B are the current maps the TSU 120 uses. The Temp map generates a map before putting it into use.

You can copy Map A to Map B by copying the Map A into the TEMP map. Then apply (write) the TEMP map into Map B.

The menu items are:

Menu Item

Description

 

 

COPY A (B) >TEMP

This copies the current map (A or B) into a

without disturbing the existing map. When

 

the modifications are completed, the Temp

 

Map is written to current MAP A (B) by

 

selecting Apply.

 

 

CREATE TEMP

This creates a map by defining a port or Idle

Network Tests

Network tests control the activation of loopbacks and the initiation of data test patterns.

Network tests are run on the Network Interface (NI). You can select three different test configurations to determine the type of loopback and the pattern to run. Test results display in the LCD window.

Executing NETWORK TESTS will disrupt normal data flow unless only TST DS0S are selected for testing.

Loopback Tests

A number of different loopbacks can be invoked locally from the front panel, by T-Watch commands, or remotely by using special in-band codes (AT&T D4 network loop-up and loopdown codes). Additionally, the loopbacks can be remotely controlled by means of out-of-band commands by the T1 ESF FDL or from T-WATCH Pro by a modem connection.

Network Interface Loopbacks

Network interface loopbacks (see Figure 7-2 on page 7-4) affect the entire T1 data stream. There are two types of network loopbacks, LINE LOOPBACK and PAYLOAD LOOPBACK.

Line 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

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

LOCAL LOOPBCK

There are three available choices for setting the local loopback:

LINE ON

Activates the line loopback

PAYLOAD ON Activates the payload loopback

NO LOOPBACK Deactivates the loopback

Using the arrow keys, select a setting and record it by pressing Enter. The unit returns the display of 1) LOCAL LOOPBCK and

2)REMOTE LOOPBCK

REMOTE LOOPBK

This activates the same loopbacks as Local Loopback but at the far end. It uses either the inband loop-up code as specified by ANSI T1.403 for line loopback (ATT In-Band LLB), or the FDL as specified in ANSI T1.403 for payload and line loopback codes. The following options are available:

ATT IN-BAND LLB Activates the line loopback using inband code

ANSI FDL PLB

Initiates the transmission of an FDL

NO LOOPBACK

Deactivates the loopback

Remote Loopback can only be used with Fractional T1 if the ANSI

FT1 LLB is selected.

After a Remote Loopback option is selected, the TSU 120 verifies that the far end is actually in a loopback by checking for the receipt of a code looped back from the far end. Once the Remote Loopback type is selected, the LCD displays the loopback progress by displaying LOOPING until loopback is verified.

Test Patterns

All Zeros

Sends an all zeros pattern to the network.

All Ones

Sends an all ones pattern to the network.

QRSS Pattern

The QRSS pattern is commonly used to simulate real data in T1 interfaces. This pattern can be assigned to appear in all DS0s or only in TST DS0s. When QRSS is set in all DS0s and one of the network loopbacks previously described is activated at the far end, a total end-to-end integrity check can be run without the need for any external test equipment. When QRSS is assigned to TST DS0s, an integrity check of the link can be run along with normal data flow. The TST DS0s are user-assigned as part of the DS0 Map. This sets the pattern for the test and initiates the transmission of the pattern. The test is terminated by selecting NONE. The following patterns are available:

61202129L1-1

TSU 120 User Manual

7-5

Chapter 7. Test Menu

QRSS ALL DS0S Generates a QRSS test pattern and inserts the pattern into all DS0s

QRSS TST DS0S Inserts a QRSS pattern in those DS0s mapped as TST in the currently active map (A or B)

NONE

Terminates pattern generation

QRSS always runs at 64K/DS0.

Example

1.Select QRSS ALL DS0S by using the Arrow Keys.

2.Press Enter to record the selection. The TSU 120 starts to generate a QRSS test pattern and inserts the pattern into all DS0s.

3.To end the test, select NONE.

PATTERN RESULT

Displays the results of the test currently active. Leaving and returning to this menu item does not interrupt the test.

Pressing 2 injects errors into the test pattern. These errors are detected by the device performing the pattern check.

ES The number of seconds with at least 1 bit error.

BES The number of seconds with more than 1 bit error and less than 320.

SES The number of seconds with more than 320 bit errors.

SYNC Indicates if pattern sync is (yes) or is not (no) valid. An asterisk (*) indicates if pattern sync has been lost since the start of testing.

Chapter 7. Test Menu

Press Shift+9 to clear results. The results are accumulated until the test pattern is set to NONE or CLEARED.

Using TST DS0s for testing can be very useful, particularly in Fractional T1 applications. You can run an end-to-end test on the Fractional DS0s by:

1.Setting for Map B the TST in the same DS0 as used by Map A to receive data from an Nx/DBU port, and

2.Looping the far end using a V.54 loopback code on the Nx/ DBU port (DBU is TSU 120e only).

In addition, a single DS0 can be used for continuous testing while other DS0s are passing normal data. This will also provide an end-to-end check on the entire link. Set each end to send QRSS in TST DS0s (using 1 DS0) and occasionally view the results on the PATTERN RESULT menu selection.

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 power-up. 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 also 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.

Chapter 7. Test Menu

The self-test consists of the following tests:

BOARD LEVEL TESTS Each of the TSU 120 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.

Executing the self-test will disrupt normal data flow and prevent remote communication until it is complete.

Port Tests

The Port Tests menu is used to activate testing of specific data ports. It controls the activation of loopbacks and the initiation of data test patterns. Test results are displayed in the LCD window.

Port tests execution will disrupt normal data flow in the port being tested.

Port Test Menu Items for 0.1 Nx56/64

0.1 Nx56/64 is the base Nx interface. It offers the following test functions:

DTE LOOPBK

This initiates a loopback. The following options are available:

PRT/LCL The Nx port activates both a Local loopback (back toward the DTE) and a Port loopback when either is invoked.

REMOTE The remote loopback causes a V.54 code to be sent to the far end. The Nx at the far end activates a PORT/LCL loopback upon detection of the V.54 code.

OFF

The loop is deactivated.

The TSU 120 checks the remote loopback activation by detecting a proper response from the remote end. While waiting for the response, the display shows Looping. If successful, the display changes to LOOPED-UP. If unsuccessful, the display shows FAILED.

511 PATTERN

This activates the generation of the 511 test pattern. The following options are available:

ON

The pattern check circuitry is enabled and a

 

test started. The test is ended by selecting

 

OFF.

OFF

The pattern generation and check is

 

disabled.

511 RESULTS

 

This displays the results of the 511 test indicated in the 511 option. The results are in the form of the number of errored seconds. The error count can be cleared by pressing Clear (Shift+9).
