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 voice band analog signal 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 specification.

• End use/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 service.

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

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 interferen ce 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.

Change or modifications to this unit not expressly approved by the party responsible for complian ce c o uld 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

Notice: The Canadian Industry and Science Canada 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 methods of connection . In so me 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 limitations 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 water pipe 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 contract 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 requirement that the total of the Load Numbers of all devices does not exceed 100.

Chapter 1 Introduction

PRODUCT OVERVIEW

The ADTRAN DSU IV ESP (data service unit with embedded SNMP) provide s a reliable, high speed data connect i on for customer data terminal equipment (DTE) through digital data service (DDS) lines. The DSU IV ESP has an embedded SNMP (simple network management protocol) agent that provides complete SNMP access to the unit through an integral SLIP or PPP async port. The DSU IV ESP's unique, modular approach provides optional 10BaseT ethernet access for SNMP . Optional ESP DBU cards are available to provide automatic or manual dial backup for the dedicated circuit.

The DSU IV ESP has the following features:

• DDS rates suppor ted from 2.4 to 64 kbps including 19.2 and

38.4

• 4-wire Switched 56 (SW56) operation

• Embedded SNMP and Telnet

• Control port provides SLIP and Async PPP access to SNMP or VT 100 terminal configuration

• Two ESP option slots

• 10BaseT ethernet SNMP port available with ESP ethernet Card

• Automatic or manual DBU

• DBU available with ESP DBU cards; options include 4-wire Switched 56, V.34, and ISDN

• Time of day and weekend DBU lockout options

The DSU IV ESP provides both V.35 and EIA-232 electrical and physical DTE interfaces to accommodate a variety of applications.

To ensure a reliable connection, the unit features an extended receiver capability which permits operation over long loops (3.4 miles or 5.5 km of 26 AWG at 56 kbps).

The ESP 4-wire SW56 DBU card and the base unit's integrated SW56 capabilities are compatible with AT&T Accunet and Sprint SW56 type services. The V.34 DBU card allows switched backup over the public switched telephone network (PSTN). The ESP ISDN 1B+D card is compatible with National ISDN and supports a Uinterface to the Basic Rate ISDN.

Figure 1-1 shows a typical point-to-point application for the DSU IV ESP.

DDS Operation Overview

DDS is a nationwide service that allows interconnection and transport of data at speeds up to 64 kbps. The local exchange carriers provide the local loop service to DDS customers and may provide data for routing InterLATA to an interexchange carrier. In DDS mode, the DSU IV ESP supports 2.4 to 64 kbps DDS service rates yielding DTE rates of 2.4, 4.8, 9.6, 19.2, 38.4 (sync or async), 56 kbps, and 64 kbps. An additional rate of 57.6 is available in asynchronous mode. The unit can be configured to run slower DTE rates (async or sync) over the 56 or 64 kbps service.

Switched 56 Operation Overview

This dial-up, 4-wire Switched 56 DDS allows customers to pay for data connection only for the time the unit is active. The regional operating companies provide the 4-wire local loop service to SW56 customers. The DSU IV ESP supports D TE rates of 2.4 , 4.8, 9.6 , 19. 2,

38.4, and 56 kbps (syn chr ono us) and 2.4 , 4.8, 9.6, 19.2, 38.4 , and 57.6

kbps (asynchronous).

Chapter 1. Introduction

SNMP OVERVIEW

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 data bases. SNMP has three basic components:

Network Manager

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

Agent

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

MIB

Index to the o rganized data wi thin a network device. It defines the operation parameters that can be controlled or monitored.

The DSU IV supports the MIB-II standard, RFC 1213, and ADTRAN Enterprise Specific MIB. MIB files are available from ADTRAN in the support section of the ADTRAN webpag e at www.adtran.com.

The DSU IV's embedded SNMP feature allows the unit to be accessed and controlled by a network manager through either a device running SLIP or async PPP protocol (connected to the CONTROL port of the DSU) or through a LAN. A LAN connection requires the opt ional ESP ethernet card (P /N 12040 05L1). Thi s card provides a 10BaseT ethernet interface to the LAN.
