ADSL IP DSLAM About This Manual Audience This book is intended for anyone who installs, manages, and configures the ADSL IP DSLAM, one product of ADSL IP DSLAM Series, via CID/RS-232 or Telnet/Ethernet CLI command interface. The ADSL IP DSLAM is a standalone IP-based DSLAM which can concentrate and manage 8/16 ADSL ports. You must have a basic understanding of ADSL related technologies, be knowledgeable about data communications, and familiar with VT-100 terminal emulation tools.
ADSL IP DSLAM 6 Troubleshooting Provides some potential problems and possible remedies and helps you diagnose and solve the problems. 7 Appendix A Presents the pin assignment for ADSL IP DSLAM 8 Appendix B Presents the SNTP time zone abbrivation. 9 Appendix C Present the deafult settings of ADSL IP DSLAM 9 Glossary Defines the key terms and acronyms mentioned in this maunal.
ADSL IP DSLAM What’s the difference between ATM based DSLAM and IP based DSLAM? Fig 0-1 & Fig 0-2 display the differences between traditional ATM-based DSLAM and ADSL IP DSLAM in PPPoE application sample. Figure 0-1 PPPoE application in Traditional ATM-based ADSL Network As Fig 0-1 displays, in traditional ATM-based ADSL network, the user application information is encapsulated by ADSL CPE into ATM cells in pre-defined VC(Virtual Channel, PVC), and then upstream the ATM cells to DSLAM via ADSL link.
ADSL IP DSLAM Figure 0-2 PPPoE application in ADSL IP DSLAM with Ethernet-All-The-Way Network In addition to traditional ATM-based ADSL network. As Fig 0-2 displays, the user application information is still encapsulated by ADSL CPE into ATM cells in pre-defined VC (Virtual Channel, PVC), and then upstream the ATM cells to DSLAM via ADSL link.
ADSL IP DSLAM 1. Introduction 1.1 General This chapter will help you understand the function and application of your ADSL IP DSLAM. It covers ADSL IP DSLAM Overview This section describes the overview of your ADSL IP DSLAM. The ADSL IP DSLAM is cost effective solution for you to complete immediate implementation of multiple of services in private and public networks. ADSL IP DSLAM Application ADSL IP DSLAM can be applied in MTU/MDU/MHU and Ethernet-all-the-way application.
ADSL IP DSLAM 1.2 ADSL IP DSLAM Overview Using the latest ADSL technology, ADSL IP DSLAM offers service providers a very cost-effective solution for immediate implementation of multiple services in private and public networks. ADSL IP DSLAM can concentrate and manage up to 16 ADSL lines. User can use local RS-232 CID and/or remote TELNET/SNMP to manage the ADSL IP DSLAM directly Since the ATM backbone coverage is not so general in the real broadband network environment.

ADSL IP DSLAM 1.3 ADSL IP DSLAM Application As the following figure shown, ADSL IP DSLAM consists of two network modules. Each network module provides eight ADSL ports with built-in POTS splitters so that it provides broadband data service over existing copper wires without affecting the conventional voice service. ADSL IP DSLAM, therefore, is a perfect solution for both central office co-location and MTU/MHU markets.
ADSL IP DSLAM 1.4 ADSL IP DSLAM Features VLAN support The ADSL IP DSLAM supports mapping of Ethernet-VLAN to ATM-PVC feature for security concern. Compact design for limited space The ADSL IP DSLAM occupies 1.5 U of standard Telco rack space. Its compactness is perfect for collocation and basement installation. With the built-in POTS splitters, service providers even no need to allocate extra space for POTS splitter shelves.

Glossary AAL ATM adaptation layer. Service-dependent sublayer of the data link layer. The AAL accepts data from different applications and presents it to the ATM layer in the form of 48-byte ATM payload segments. AALs consist of two sublayers: CS and SAR. AALs differ on the basis of the source-destination timing used (CBR or VBR) and whether they are used for connection-oriented or connectionless mode data transfer. At present, the four types of AAL recommended by the ITU-T are AAL1, AAL2, AAL3/4, and AAL5.
