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.

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

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 for filing an affidavit with the local exchange carrier when

connecting unprotected customer premise equipment (CPE) to 1.544 Mbps or subrate digital services.

• Until such time as subrate digital terminal equipment is reg istered for voice applications, the affi-

davit requirement for subrate services is waived.

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 ope rate to the user's satisfaction.

Before installing this equipment, users should ensure that it is permissible to be con nected to th e 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 awar e that compliance with the abo ve conditions may not pr event 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 ad apter is used to dete rmine 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.

Frame Relay

Frame relay is a packet-switched service that allows efficient transfer of bursty traffic in a WAN environment. It offers lower-co st data transfer when compared to typical point-to-point applications. U sing virtual connections within the frame relay network and combining those into a single physical connection at each location result in lower cost. Frame relay providers use a frame relay switch to route the data on each virtual circuit to the appropriate destination. Figures 1-1 and 1-2 illustrate a conversion from a typical pointto-point application to a frame relay application.

Dedicated and Switched Connection Maps in a Single Platform

The ATLAS 810

PLUS

allocates dedicated bandwidth according to any of up to five unique connection maps. Any DS0 on any T1 circuit can be mapped to any other DS0 on up to 34 T1 circuits in the system. Dedicated co nnection maps can be manually invoked or automatically implemented based on the time of day and day of the week.

Additionally, the ATLAS 810 specific ports or DS0s based on the number that is dialed. Switched connection mapping is supported for dialup calls placed over basic rate ISDN, primary rate ISDN, or channelized T1.

Signaling Conversion for Maximum Interoperability

The ATLAS 810

PLUS

can convert between Robbed Bit Signaling and ISDN D channel signaling, giving you the flexibility to get the speed and reliability of ISDN, while preserving your investment in non-ISDN equipment. ATLAS can also convert between D4 and ESF frame forma ts as well as AMI and B8ZS line coding, providing interoperability with legacy equipment.

, including SNMP support. VT 100 and Telnet are also offered, providing detailed system configuration through an easy-to-use menu system. The terminal interface is secured by six levels of password protection with varying degrees of management privileges. The terminal interface is accessed locally or remotely using either the EIA-232 Chain In po rt on the rear of the unit or the Telnet interface. The 10BaseT interface on the Base Unit provides an Ethernet connection for SNMP and Telnet connections.

Additionally, T-Watch PRO, ADTRAN’s Microsoft

Windows®-based GUI management system, allows end-to-end management with downstream ADTRAN T1 products. User configurations can be preserved in non-volatile memory and duplicated for managing multiple ATLAS implementations. ATLAS also supports FLASH upgrades for future enhancements. You can remotely download software using TFTP or XMODEM.

The ATLAS 810

PLUS

front panel contains an extensive array of LEDs for alarm and status information pertaining to the system and the individual modules.

Several test capabilities allow you to diagnose the health of your T1, PRI, or BRI circuits without additional test equipment. Standard Bantam test jacks

located on the ATLAS 810

PLUS

rear panel also allow you to use external test equipment to monitor traffic. Tests include local, remote, and V.54 loopbacks utilizing the 511, QRSS, all zeros, and all ones test patterns.

Digital Access Cross-Connect System (DACS)

Inherent in the ATLAS 810

PLUS

architecture is the ability to cross connect, or DACS, up to thirty-four T1 circuits. DACSing allows the assignment and redistribution, or grooming, of any DS0 on any T1 circuit to any other DS0 on any of the thirty-four T1 circuits in the system. For optimizing network resources, any of five dedicated connection maps can be invoked manually or automatically, based on the time of day and day of the week (see Figure 1-3).

T1 Bandwidth Manager

PLUS

As a T1 Bandwidth Manager, ATLAS 810

combines the functions of a T1 CSU/DSU, an intelligent channel bank, a T1 Multiplexer, and DACS into a single platform. The Bandwidth Manager supports a wide ran g e of da ta applications including T1 “drop and insert,” channel groo ming, and wide area data transport. ATLAS is ideal for point-to-point configurations or access to public networks. For optimization of existing equipment and network resources, ATLAS can be paired with ADTRAN’s TSU product offerings to support a variety of data and analog voice applications (see Figure 1-4).

ISDN Access Switch

The ATLAS 810

PLUS

includes an advanced access architecture for switching dialup calls to specific ports or DS0s. As an access switch functioning in a user-to-user network and user-to-user mode, ATLAS consolidates multiple basic rate ISDN (BRI) connections onto T1/PRI access lines. Additionally, BRI-to-BRI, BRI-to-PRI, and PRI-to-PRI switching are supported. ATLAS also converts between ISDN D channel (PRI or BRI) and T1 Robbed Bit Signaling, allowing a non-ISDN PBX to access a more efficient ISDN facility. For network optimization, when bandwidth is not being used for switched applications such as video conferencing, switched connection mapping dynamically allocates bandwidth to the PBX f or voice traffic. Call Filtering allows you to program the call types that will be answered and/or originated on a per-user basis.

WAN Overbooking

The WAN Overbooking feature of ATLAS 810 scribe switched bandwidth for situations where simultaneous access to the network by every subscriber is not required. WAN Overbooking reduces telecommunications expenses while still giving your subscriber base the connectivity they require. Local subscriber-to-subscriber connections are made without accessing the network at all, resulting in even more efficient use of wide area bandwidth (see Figure 1-5 on page 1-6).
