1. Scope This Engineering Instructions document describes about the Technology, Services and Installation procedures, functional details of DNA-A201BEI CPE (Type 1) & DNA-A211-I CPE/Router(Type-2) which is supplied by M/s ITI Limited., Bangalore, through their technology partner M/s SemIndia Systems Private Limited., Bangalore to BSNL. This document is prepared assuming that most of the customers will be using windows operating system. However other Operating Systems like Linux, Macintosh are also supported.

2. Introduction DNA-A201BEI and DNA-A211-I are ADSL/ADSL2/ADSL2+ CPE/Routers which delivers High speed data over existing phone lines without interfering with the voice signals. The frequency of the ADSL signal is higher than that of voice, so voice and ADSL signal can coexist in one line by using a splitter to insulate each from the other.

DNA-A201BEI supports 1Ethernet and 1 USB interfaces and DNA-A211-I supports 4 Ethernet ports and 1 Wi-Fi interface.

3. Technology General An ADSL2+ CPE/Router is a broadband Internet access device, which utilizes the high frequency segment of the phone line to transmit high-speed data without affecting the voice transmission. ADSL2+ data transfer adapts the asymmetry model. It supports upload transmission speed up to 1Mbps and download speed up to 24Mbps. Both are backward compatible with standard ADSL. Simple and easy to operate and establish connection to Internet, and both the models support TR-064, compatibility with BSNL’s infrastructure is ensured. Thess devices also support TR-069, which ensures remote management by BSNL to automatically update the firmware and other settings.

3.1 Key Features supported by both models of CPE • Web-based configuration, upgrade, backup and status.

• Built in Firewall option includes IP filtering, MAC filtering, DMZ.

• Built in NAT option.

• Built in Diagnostics

• Supports TR-64, TR-69.

• Supports IP Multicast, IGMP v1/v2, FTP, TFTP, IPV6.

• Supports Virtual Server and Port Mapping.

• Support up to 8 PVC’s.

• Compatible and interoperable with most central office side ADSL DSLAM or Multi-service. • Interchangeable between Bridge and Router mode. • QoS (802.1P) support.

• Routing function.

• DHCP function.

• Maximum downstream transmission rates of 24Mbps for ADSL2+.

• Maximum upstream transmission rates of 1Mbps

• Transmission distance up to 6 km.

DNA – A 201 BEI (Type 1) DNA – A 211-I (Type 2)

• One 10/100BaseT Ethernet Port for PC/LAN connection.

• One USB 1.1 full speed port for PC connection.

7. Do’s and Don’ts (Common to both Models) 7.1 Do’s To reduce the risk of fire, electric shock and injury, please adhere to the following safety guidelines: • Understand and implement the standard electrical safety, electrical

wiring and connection practices. • Knowledge on using tools and instruments for installation and testing is

recommended to avoid damage or injury to both person and the equipment.

• Carefully follow the instructions in this document; also follow all instruction labels on this device. • Except for the power adapter supplied, this device should not be

connected to any other adapters. • It is recommended to always use the splitter supplied along with the

CPE. Failing to use may damage your CPE.

7.2 Don’ts • Do not spill liquid of any kind on this device. • Do not place the unit on an unstable stand or table. This unit may drop

and may get damaged.

• Do not expose this unit to direct sunlight. • Do not place any hot devices close to this unit, as they may degrade or

cause damage to the unit.

• Do not place any heavy objects on top of this unit. • Do not use liquid cleaners or aerosol cleaners. Use a soft dry cloth for

cleaning. • Do not bend or turn the Wi-Fi antenna.

7.3 Fault Analysis

It was noticed during fault analysis of the field returned DNA-A211-I (Type 2) modems that DSL section was damaged in some Modems received from Coastal Areas (Kerala & Mangalore). M/s ITI deputed its technology partner M/s SEM India’s team of Engineers to analyze the Cause and field survey was conducted. It was found that some of the Installed Modems were not connected through the supplied Splitter. Splitter supplied along with the Modem has K.21 Protection Circuitry which is primary protection for Modem against the Lightening and Surge voltages. It is always recommended that the splitter is installed and LJU is used in the installation. Refer -Figure 6 (Page 16) for diagrammatic representation of the installation to be followed.

8. Conclusion ADSL2+ CPE/Router is an ideal device for broadband access; IPTV over Broadband Connection, Internet Gaming Services, IP based Video Conferencing which complies with ITU G.992.1, G.992.2, G.992.3, and G.992.5, Annex-A/M ADSL standards. Both the CPEs provide high speed Internet access via one WAN port over ATM over ADSL, and also connects to the corporate network via a 10/100BaseT Ethernet port. Both the CPEs offer convenient configuration and management locally by telnet, SNMP, and a web-browser through the Ethernet interface, and remotely through the ADSL interface. Also support TR-64 LAN management protocol for Zero touch Broadband activation and customer care.

10. Terminology • TR-64: It is the CPE LAN Management protocol. This protocol allows

a local user to view and change the settings of the CPE.

• TR-69: It is the CPE WAN Management protocol. This protocol allows a remote user to view and change the settings of the CPE.

• IP Multicast: This is a type of communication in which a single host sends data to a group of receivers.

• IGMP V1/V2: Internet Group Management Protocol is a protocol used for multicasting. IP hosts use this protocol to report their host group memberships to any immediately neighboring multicast routers. V1 and V2 are the two different versions of IGMP.

• IPV6: It is the second generation of the Internet Protocol. This is an extended version of the current IPV4 implementation of IP address to include larger address space than IPv4. This results from the use of a 128-bit address, whereas IPv4 uses only 32 bits. The new address space thus supports 2128 (about 3.4×1038) addresses. This expansion provides flexibility in allocating addresses and routing traffic. IPv6 also implements new features that simplify aspects of address assignment (stateless address auto configuration) and network renumbering (prefix and router announcements) when changing Internet connectivity providers.


25

• Port Mapping: It is a feature which allows different ports to be mapped to different IP addresses so that any traffic arriving at those ports will be forwarded to the corresponding IP addresses to which it is mapped.

• PVCs: Permanent Virtual Circuit is a temporary communication path created between devices in a switched communications system. It is a software-defined logical connection in a network.

• VPI: Virtual Path Identifier is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination.

• VCI: Virtual Circuit Identifier, together with the Virtual Path Identifier (VPI) is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination.
