General Safety Instructions The following instructions serve as a general guide for the safe installation and operation of telecommunications products. Additional instructions, if applicable, are included inside the manual. Safety Symbols This symbol may appear on the equipment or in the text. It indicates potential safety hazards regarding product operation or maintenance to operator or service personnel.
Handling Energized Products General Safety Practices Do not touch or tamper with the power supply when the power cord is connected. Line voltages may be present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards may still exist.
Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the circuit breaker of the panel board that services the equipment and switch it to the OFF position. When connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the positive pole and last the negative pole. Switch the circuit breaker back to the ON position.
there are restrictions on the diameter of wires in the telecom cables, between the equipment and the mating connectors. Caution To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords. Attention Pour réduire les risques s’incendie, utiliser seulement des conducteurs de télécommunications 26 AWG ou de section supérieure. Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only.
FCC-15 User Information This equipment has been tested and found to comply with the limits of the 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.

Chapter 1 Introduction 1.1 Overview ASM-40 is a high speed, synchronous short-range modem operating at full-duplex over unconditioned lines. ASM-40 also functions as a baud rate and interface converter. Product Options The following versions of the modem are available: • ASM-40 standalone unit • ASM-40/R: a plug-in card for installation in the ASM-MN-214, 19-inch modem rack, holding up to 14 cards.
Chapter 1 Introduction Installation and Operation Manual Features ASM-40 operates at 13 selectable rates of up to 2048 kbps, for a line attenuation of up to 40 dB on twisted pair or coax cable. This provides an approximate operating range of up to 1.75 km (1 mile). ASM-40 incorporates interface circuits for the terminal/computer, an automatic equalizer, a modulator and demodulator.
Installation and Operation Manual 1.2 Chapter 1 Introduction Physical Description ASM-40 is available as a standalone unit or as a rack-mount card for the ASM-MN-214 hub. Figure 1-3 shows the 3D view of the ASM-40 standalone unit. Figure 1-3.

Appendix D IR-IP Interface Module D.1 Introduction Overview IR-IP is a high-performance, miniature IP router based on RAD's unique IP router chip, the ChipRouter. IR-IP works by taking each Ethernet frame from the LAN and determining whether the IP packet is destined for the IP net on the Ethernet LAN. If not, IR-IP forwards the packet to the WAN (line) link. IP packets received from the WAN link are automatically forwarded to the LAN if the IP net matches.
Appendix D IR-IP Interface Module Installation and Operation Manual Application Figure D-1 shows a typical application of the ASM-40 modem equipped with the IR-IP interface module. ASM-40 with IR-IP ASM-40 with V.35 Interface Router Figure D-1. Typical Application of ASM-40 with IR-IP D.
Installation and Operation Manual Appendix D IR-IP Interface Module IR-IP LEDs IR-IP contains three LEDs, which indicate module activity. Table D-1 lists the LEDs functions. Table D-1. IR-IP LEDs Functions Name Type Function INT Green LED ON – LAN integrity is established. ACT Yellow LED Blinking – Transmit/receive activity is detected on the Ethernet link. ERR Red LED ON – Buffer overflow occurred (during normal operation). During power-up, provides additional indications, as described below.
Appendix D IR-IP Interface Module Installation and Operation Manual IR-IP DIP Switch (Card version) IR-IP interface module on the card version of ASM-40 contains a six-section DIP switch, as seen in Figure D-3. Table D-2 lists the DIP switch functions. Figure D-4. IR-IP DIP Switch (card version) Table D-3. IR-IP DIP Switch Functions No Function Values Default Setting 1 – N/A – 2 Controls the remote WAN test loopback.
Installation and Operation Manual D.
Appendix D IR-IP Interface Module Installation and Operation Manual After configuring IR-IP, it starts normal operation and routes the traffic in accordance with the user-selected configuration parameters. To change the parameters of an already-configured IR-IP, establish communication from a Telnet host using the assigned IP address. Default IP Communication Parameters The default IP communication parameters of the interface module are: • The default IP address of the IR-IP Ethernet port is 192.168.
Installation and Operation Manual Appendix D IR-IP Interface Module 4. Establish again communication with IR-IP and continue the preliminary configuration in accordance with the Quick Setup Menu section below. Connecting the Telnet Host Before starting the management and configuration activities, it is necessary to establish IP communication between your Telnet host and the IR-IP interface module. For this purpose, it is necessary to provide a communication path.
Appendix D IR-IP Interface Module Installation and Operation Manual The IP learning mechanism enables IR-IP to learn its LAN interface IP address by receiving frames sent by a ping utility to the prescribed LAN IP address. Note To use the IP learning mechanism, you do not need to know the current address of IR-IP LAN interface, but only the prescribed IP address. The IP address is actually retrieved from the ARP frames sent during pinging to locate the ping destination, not from the ping frames.
Installation and Operation Manual Appendix D IR-IP Interface Module The ERR indicator must turn off. At this stage, the communication with IR-IP router is lost, because its IP address has been changed. Therefore, you must reconfigure the destination IP address of the Telnet host. If you wish, you may also change the temporary IP address assigned to the host (192.168.205.2) back to its permanent address.
Appendix D IR-IP Interface Module Installation and Operation Manual No ping replies from IR-IP • If your host does not begin to receive ping replies after three unsuccessful attempts, check the physical connection path between the Telnet host Ethernet interface and the IR-IP 10BASE-T connector. The IP learning process is not successful • Check that the prescribed IP address does not appear in the ARP table. D.

Appendix D IR-IP Interface Module Note Installation and Operation Manual If you do not set sections 1 and 2 to OFF within 15 seconds of power-up, the IP router card ignores the setting of all the four sections to ON and starts normal operation. In this case, it is recommended to turn ASM-40 off and then back on. To abort the whole operation, turn ASM-40 off, return all the four-switch section to the desired positions, and then turn ASM-40 on again. 5.

Appendix E IR-G.703 Interface Module E.1 Introduction IR-G.703 is an interface module for RAD modems, converting G.703 64 kbps codirectional signals to TTL levels. The converted data is sent over the modem link using the modem modulation technique and converted back at the other end into G.703 64 kbps codirectional signals, or into any other digital interface signal possible. Note For the G.703 codirectional interface, end-to-end byte synchronization is not maintained.
