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 registered for voice applications, the affidavit
requirement for subrate services is waived.

FCC regulations require that the following information be provided in this manual:
1. This equipment complies with Part 68 of FCC rules. On the back of the equipment housing is a
label showing the FCC registration number and ringer equivalence number (REN). If requested,
provide this information to the telephone company.
2. If this equipment causes harm to the telephone network, the telephone company may temporarily
discontinue service. If possible, advance notification is given; otherwise, notification is given as
soon as possible. The telephone company will advise the customer of the right to file a complaint

dial-up line for the V.34 modem:
8. The REN is useful in determining the quantity of devices you may connect to your telephone line
and still have all of those devices ring when your number is called. In most areas, the sum of the
RENs of all devices should not exceed five. To be certain of the number of devices you may
connect to your line as determined by the REN, call your telephone company to determine the
maximum REN for your calling area.
9. This equipment may not be used on coin service provided by the telephone company. Connection
to party lines is subject to state tariffs. Contact your state public utility commission or corporation

1. EXPRESS 6503 OVERVIEW
The Express 6503 is a serial (DCE) to SHDSL data service unit (DSU) designed for small offices and
branch offices to provide cost-effective access to high-speed SHDSL services. The Express 6503 preserves
the customer's investment in existing business class routers, allowing them to take advantage of New
World applications and Packet Telephony. It offers an economical migration path utilizing ATM and Frame
Relay over SHDSL without requiring replacement of existing networking equipment.
The Express 6503 provides small offices and branch offices with fast, affordable, and easy-to-use access to
the Internet and corporate network. The Express 6503 makes DSL services and applications accessible to
the office router or to the desktop. It supports an integrated SHDSL WAN interface and a serial interface to
the router and can operate at symmetric speeds of up to 2312 kbps.
On the Express 6503, the terminal menu is the access point to all other operations. Each terminal menu
item has several functions and submenus that identify and provide access to specific operations and
parameters. These menu selections are described later in this User Interface Guide (pages 18 and
following).
Express 6503 Features and Benefits
• SHDSL WAN Support (ITU-T G.991.2) - The Express 6503 supports serial full duplex bidirectional
data transport of up to 2312 kbps.
• ITU G.hs (ITU-T G.994.1) Support
• TC PAM Line Encoding - Compliant with the SHDSL standard.
• Back-to-back operation for Campus LAN applications.
• Synchronous Serial Interface - The serial interface can support either V.35 or X.21 protocols.
• AAL5 ATM Adaptation Layer Type 5 Support.
• FRF.8 Frame Relay to ATM Interworking Support - The Express 6503 supports FRF.8 Frame/ATM
service interworking. It maps Frame data-link connection identifiers (DLCIs) to ATM permanent
virtual circuits (PVCs); up to four VCs can be configured in the Express 6503.
• FRF.5 Frame Relay to ATM Interworking Support - DLCIs can be assigned automatically or
provisioned.
• Management Support - The Express 6503 is managed through a command-line interface accessible
locally through the management serial port or remotely through Layer 3 in-band management features.
• Safety and Compliance - The Express 6503 is designed for worldwide safety and electromagnetic
certifications (EMC).
