Chapter 1 Introduction 1.1 Functional Description Purpose and Main Features The ASMi-450 is a high-speed HDSL modem that enables long-range data transmission over one unconditioned twisted-pair line, using the High Bit Rate Digital Subscriber Line (HDSL) technology. The HDSL technology offers a cost-effective and reliable solution for delivering high-speed data to the subscriber premises over the existing copper cables and subscriber loops of the local distribution plant.
Introduction • Ethernet 10BaseT interface. The interface can use unshielded and shielded twisted pair (UTP and STP) media. The ASMi-450 also includes a remote bridge, that can be enabled/disabled by the user. Figure 1-1 shows a typical application for an ASMi-450 with serial data interface, and figure 1-2 shows a typical application for an ASMi-450 with Ethernet interface. LAN LAN HDSL Line V.35 V.35 768kbps BRIDGE 768kbps ASMI-450 ASMI-450 BRIDGE Figure 1-A.
Introduction The interface includes a full-feature remote bridge, that operates at the physical and data link layers of the OSI model, and is therefore completely transparent to higher level protocols, such as TCP/IP, DECnet, XNS, ISO, and to operating systems, such as NetWare, VINES, and 3COM+.
Introduction • The remote unit, located at the remote end of the link (customer side), serves as the network termination unit (NTU). The ASMi-450 supports both the central (LTU) and the remote (NTU) operating modes; the actual operating mode (LTU or NTU) is user-selectable. System Timing The ASMi-450 offers selectable timing options, which enable the distribution of timing over the HDSL system, from the central office to the remote end. • ASMi-450 Unit Configured as Central Unit (LTU).

Flow of Timing Signals through ASMi-450 System in the Internal Timing Mode • Control of ASMi-450 Operation ASMi-450 Unit Configured as Remote Unit (NTU).
Introduction The remote management functions are performed through a serial RS-232 port that enables serial communication with a supervision terminal. Using the supervision terminal functions, the user can also enable remote management using IP communications, i.e., Telnet and SNMP. The IP communication uses the Serial Link Internet Protocol (SLIP). Note Support for Telnet and SNMP is available for ASMi-450 with software version 1.0 and higher.
Introduction Test and Diagnostics Capabilities The ASMi-450 has comprehensive diagnostics capabilities. ASMi-450 models with serial data port support the following types of test functions: • Local loopback on the user's port of the local ASMi-450 (LOOP LOCAL PORT). • Remote loopback on the user's port of the remote ASMi-450 (LOOP REM REM PORT).
Introduction 1.2 Operating Environment This section describes the HDSL environment, with special emphasis on the implementation used in the ASMi-450 to provide the background information required for understanding the configuration parameters of the ASMi-450 system. Transmission Media HDSL systems are intended to operate on the local subscriber plant, which typically uses a mixture of unshielded twisted-wire pairs. Moreover, it also necessary to tolerate bridges taps.
Introduction By reducing the line symbol rate, the maximum range that can be reached is increased. This is achieved by offering several versions of ASMi-450, each operating up to a given maximum rate. Together with the advanced digital signal processing techniques implemented in HDSL systems, this results in a robust data transmission system that can reliably operate over regular unconditioned local loops. HDSL Signal Structure The HDSL signal is organized in frames.

Diagnostics 5.3 Test Functions Test Functions The ASMi-450 supports the following types of test functions: • Local loopback on the user's port of the local ASMi-450 (LOOP LOCAL PORT). • Remote loopback on the user's port of the remote ASMi-450 (LOOP REM REM PORT). The loopbacks are not available for an ASMi-450 with the Ethernet interface. The user-controlled test functions are accessed from the TEST OPTIONS menu.
Diagnostics LOOP REM REM PORT When the remote user's port loopback is activated, the user's port interface of the remote ASMi-450 returns the received data signal toward the local user's DTE. The remote loopback is performed by internally connecting the DCE receive signal, to the input of the transmit path. The received data signal remains connected to the remote user's DTE.

Appendix B SNMP Management B.1 Scope This Appendix provides the specific information required for the management of the ASMi-450 by means of the Simple Network Management Protocol (SNMP). An ASMi-450 unit configured as the central unit serves as a proxy agent for the remote unit to which it is connected. Therefore, an SNMP-based network management station connected to a central ASMi-450 unit can perform all the management functions available on the remote unit.
SNMP Management B.2 SNMP Environment General The SNMP management functions of the ASMi-450 are provided by an internal SNMP agent, which is communicate through the ASMi-450 control port using the Serial Link Internet Protocol (SLIP). The SNMP management communication uses the User Datagram Protocol (UDP). UDP is a connectionless-mode transport protocol, part of the suite of protocols of the Internet Protocol (IP). Note Telnet management uses the TCP protocol over IP for management communication.
SNMP Management The Management Information Base The management information base (MIB) includes a collection of managed objects. A managed object is defined as a parameter that can be managed, such as a performance statistics value. The MIB includes the definitions of relevant managed objects. Various MIBs can be defined for various management purposes, types of equipment, etc.
SNMP Management In addition, the ASMi-450 SNMP agent supports the RAD-private (enterprisespecific) MIB. • For ASMi-450/1152, the RAD-private MIB is identified as (read the following as a continuous string): iso(1).org(3).dod(6).internet(1).private(4).enterprise s(1).rad(164).radGen(6).systems(1).radSysWAN(3).radASM i450R1152Sa • For ASMi-450/768, the RAD-private MIB is identified as: iso(1).org(3).dod(6).internet(1).private(4).enterprise s(1).rad(164).radGen(6).systems(1).radSysWAN(3).
SNMP Management When an SNMP message is received by the addressed entity, first it checks the originator's community: if the community name of the message originator differs from the community name specified for that type of message in the agent, the message it discarded (SNMP agents of managed entities report this event by means of an authentication failure trap).
SNMP Management B.3 IP Environment General The SNMP agent of the ASMi-450 communicates using the Serial Link Internet Protocol (SLIP). IP Environment The SNMP agent of the ASMi-450 uses either the UDP or the TCP transport protocol, part of the suite of IP protocols. IP Address Structure Under the IP protocol, each IP network element (SNMP agents, network management stations, etc.) is called an IP host and must be assigned an IP address.
SNMP Management • Host Portion. The host portion is used to identify an individual host connected to the network. The host identifier is assigned by the using organization, in accordance with its specific needs. Note The all-zero host identifier is always interpreted as a network identifier, and must not be assigned to an actual host. Often, the host portion is further sub-divided into two portions: à Subnet number. For example, subnet numbers can be used to identify departmental subnetworks.
SNMP Management B.4 SNMP Traps The SNMP agent of the ASMi-450 supports the standard MIB-II traps. In addition, ASMi-450 reports alarm conditions to the management station by mean of specific traps: B-8 • When an alarm condition occurs, the ASMi-450 sends a modmSaAlarmTrap which carries all the alarms active at the time the trap is sent.
Appendix C Installation in 19" Racks C.1 General The ASMi-450 can be installed in 19" racks. Unit height corresponds to 1U (1.75"), and the width is slightly less than half of the available mounting width. Two rack adapter kits are available; one kit provides the hardware necessary for installation of a single unit, and the other provides the hardware necessary for installation of two units, side by side. This Appendix provides step-by-step installation instructions for each option.

Installation in 19" Racks Fastening the Two Units • Fasten one short adapter bracket to the left-hand side wall of the unit intended to be on the left. Use two of the four longer screws supplied in the kit, and insert flat washers. • Use the same procedure to fasten the second short adapter to the right-hand wall of the unit intended to be on the right.
ASMi-450 Installation Instructions for Compliance with EMC Requirements To comply with electromagnetic compatibility requirements, two ferrite cores should be installed on any: • HDSL line cable with an RJ-45 connector (using a STEWARD catalog number 28A2029-0A0 core or equivalent). • DCE port line unshielded data cable with any connector (using a STEWARD catalog number 28A2024-0A0 core or equivalent). This limits the electromagnetic energy emitted from the cables.
