Users are alerted that RAD cannot be held responsible for any damage that may result if non-compliant transceivers are used. In particular, users are warned to use only agency approved products that comply with the local laser safety regulations for Class 1 laser products.

Always observe standard safety precautions during installation, operation and maintenance of this product. Only qualified and authorized service personnel should carry out adjustment, maintenance or repairs to this product. No installation, adjustment, maintenance or repairs should be performed by either the operator or the user.

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 working on equipment connected to power lines or telecommunication lines, remove jewelry or any other metallic object that may come into contact with energized parts.

Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug is provided on the product, it should be connected to the protective earth at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks and cabinets.

Always make the ground connection first and disconnect it last. Do not connect telecommunication cables to ungrounded equipment. Make sure that all other cables are disconnected before disconnecting the ground.

Connection of AC Mains Make sure that the electrical installation complies with local codes.

Always connect the AC plug to a wall socket with a protective ground.

The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A. The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A.

Always connect the power cord first to the equipment and then to the wall socket. If a power switch is provided in the equipment, set it to the OFF position. If the power cord cannot be readily disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency switch is installed in the building installation.

In cases when the power distribution system is IT type, the switch must disconnect both poles simultaneously.

Connection of DC Mains Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the ground. Any single pole can be externally grounded.

Due to the high current capability of DC mains systems, care should be taken when connecting the DC supply to avoid short-circuits and fire hazards.

DC units should be installed in a restricted access area, i.e. an area where access is authorized only to qualified service and maintenance personnel.

Make sure that the DC supply is electrically isolated from any AC source and that the installation complies with the local codes.

The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A. The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A.

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.

A readily accessible disconnect device that is suitably rated and approved should be incorporated in the building installation.

If the DC mains are floating, the switch must disconnect both poles simultaneously.

Connection of Data and Telecommunications Cables Data and telecommunication interfaces are classified according to their safety status.

The following table lists the status of several standard interfaces. If the status of a given port differs from the standard one, a notice will be given in the manual.

Ports Safety Status

V.11, V.28, V.35, V.36, RS-530, X.21, 10 BaseT, 100 BaseT, Unbalanced E1, E2, E3, STM, DS-2, DS-3, S-Interface ISDN, Analog voice E&M

SELV Safety Extra Low Voltage:

Ports which do not present a safety hazard. Usually up to 30 VAC or 60 VDC.

xDSL (without feeding voltage), Balanced E1, T1, Sub E1/T1

TNV-1 Telecommunication Network Voltage-1:

Ports whose normal operating voltage is within the limits of SELV, on which overvoltages from telecommunications networks are possible.

FXS (Foreign Exchange Subscriber) TNV-2 Telecommunication Network Voltage-2:

Ports whose normal operating voltage exceeds the limits of SELV (usually up to 120 VDC or telephone ringing voltages), on which overvoltages from telecommunication networks are not possible. These ports are not permitted to be directly connected to external telephone and data lines.

FXO (Foreign Exchange Office), xDSL (with feeding voltage), U-Interface ISDN

TNV-3 Telecommunication Network Voltage-3:

Ports whose normal operating voltage exceeds the limits of SELV (usually up to 120 VDC or telephone ringing voltages), on which overvoltages from telecommunication networks are possible.

Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a qualified safety engineer.

Always make sure that the equipment is grounded before connecting telecommunication cables. Do not disconnect the ground connection before disconnecting all telecommunications cables.

Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables. Extra caution should be exercised during thunderstorms.

When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The earthing and bonding of the ground connections should comply with the local codes.

The telecommunication wiring in the building may be damaged or present a fire hazard in case of contact between exposed external wires and the AC power lines. In order to reduce the risk, there are restrictions on the diameter of wires in the telecom cables, between the equipment and the mating connectors.

To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.

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. In such cases, a notice will be given in the installation instructions.

Do not attempt to tamper with any carrier-provided equipment or connection hardware.

Electromagnetic Compatibility (EMC) The equipment is designed and approved to comply with the electromagnetic regulations of major regulatory bodies. The following instructions may enhance the performance of the equipment and will provide better protection against excessive emission and better immunity against disturbances.

A good earth connection is essential. When installing the equipment in a rack, make sure to remove all traces of paint from the mounting points. Use suitable lock-washers and torque. If an external grounding lug is provided, connect it to the earth bus using braided wire as short as possible.

The equipment is designed to comply with EMC requirements when connecting it with unshielded twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on certain cables. In such cases, special instructions are provided in the manual.

Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.

The compliance of the equipment with the regulations for conducted emission on the data lines is dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss (LCL).

Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary protection against surges on the data lines. Primary protectors should be provided in the building installation.

The equipment is designed to provide adequate protection against electro-static discharge (ESD). However, it is good working practice to use caution when connecting cables terminated with plastic connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist strap.

Figure 1-4. Asynchronous Channels over X.25 Network

Figure 1-5. Synchronous Channels over Frame Relay

Figure 1-4 illustrates how asynchronous channels function according to the X.3, X.28 and X.29 profiles, at traffic speeds of up to 115.2 kbps. Figure 1-5 shows how a synchronous traffic can be packetized directly over the Frame Relay network, or packetized over the X.25 network. All channels are configured and monitored by the SPS-4 management agent.

Functions The following are protocols supported by SPS-4.

Frame Relay

SPS-4 provides access and switching to public or private Frame Relay networks, and consolidates asynchronous, HDLC, IP and X.25 traffic over the Frame Relay network.

As a Frame Relay switch, SPS-4 integrates DLCIs from several sources into a single port. It also supports BECN/FECN signaling for congestion avoidance.

A unique funneling mechanism adjusts feeder throughput to CIR levels.

The Frame Relay multicasting feature (complies with FRF-7) enables multicasting frames from one DLCI onto several DLCIs. This feature supports one-way, two-way and broadcast communication options.

LMI and ANSI PVC management protocols are supported in compliance with ANSI T1.606, T1.618, T1.617 Annex D, and ITU Rec. Q.922, Annex A.

SPS-4 supports CLLM management protocol and complies with ITU REC Q.933, Annex A.


SPS-4 Ver. 5.25 Functional Description 1-5

Ethernet

The Ethernet interface is optional and is not included by default. It enables bridging and/or routing of LAN packets over a Frame Relay network (according to RFC 1490) and over an X.25 network (according to RFC 1356).

X.25

X.25-configured links support permanent virtual circuits (PVCs) and switched virtual circuits (SVCs). Link packet size is up to 4096 bytes.

SPS-4 supports both mandatory and additional ITU X.25 facilities.

Dial-up X.25 links are supported via a dial-up modem, controlled by a DTR signal or V.25 bis commands.

SPS-4 supports X.25 multicasting.

X.32

SPS-4 supports the X.32 protocol for a dial-up X.25 link. This enables users to access an X.25 network remotely via a dial-up modem with X.32, or to use the backup dial-up link for an X.25 or Frame Relay network.

HDLC Transparent Access

Each port can be programmed to operate in transparent HDLC mode for connecting bridges, routers and other HDLC communication devices over X.25 or Frame Relay networks. The HDLC protocol is encapsulated over X.25 or Frame Relay, providing end-to-end transparent operation.

Asynchronous Access

All asynchronous channels function according to the X.3, X.28, and X.29 profiles at traffic speeds of up to 115.2 kbps. Asynchronous traffic can be packetized directly over the Frame Relay network, or packetized over the X.25 network. All channels are configured and monitored by the SPS-4 management agent.

Each SPS-4 port can be configured to SLIP or PPP mode, operating at data rates of up to 115.2 kbps.

IP PAD facilities allow straightforward migration of terminal/server applications to an IP environment, while improving its durability at the same time.

IP Routing

SPS-4 routes IP datagrams over Ethernet, PPP or SLIP links and over Frame Relay networks (according to RFC 1490), or over X.25 networks (according to RFC 1356).

SPS-4 supports RIP1, RIP2 and triggered acknowledgment RIP messages (according to RFC 1058, 1723 and 1724). The RIP support enables trouble-free IP connections while minimizing IP user configuration. The triggered RIP enables reduction of the overhead associated with the RIP mechanism by minimizing the number of periodic messages sent.


1-6 Functional Description SPS-4 Ver. 5.25

Management Capabilities The unit can be managed using different ports and applications:

• Local out-of-band management via an ASCII terminal connected to the RS-232 port

• Remote inband management using RADview-Lite, RAD's SNMP-based management system.

The SNMP agent can be programmed to periodically send statistics and status reports to a maximum of five management stations.

A management station can be connected directly to SPS-4 using LAN, PPP or SLIP.

The SPS-4 SNMP agents support private and standard MIBs, including MIB II with RFC 1213, RFC 1381 and RFC 1382 for X.25, and RFC 1315 for Frame Relay.

Backup and Recovery SPS-4 supports stream backup over GPRS networks.

After a network recovery, SPS-4 automatically synchronizes itself with the main facility link.

Connecting the Asynchronous Control Channel The SPS-4 control channel interface is always configured as a data communication equipment (DCE) interface, thereby allowing direct connection via RS-232 port cables to data terminal equipment (DTE).

The asynchronous control interface includes a 9-pin, D-type female connector.

To connect the Asynchronous Control channel:

• Connect the RS-232 port cables to the connector(s) corresponding to the interface in use.

If modems are used to extend the range (tail-end circuits), cross-over cables are required.

Channel interfaces are asynchronous; therefore clock signals are neither supported nor required.

Connecting the Synchronous Links When the SPS-4 synchronous link interfaces are set as DTE interfaces, it is intended to be connected to synchronous modems that are capable of providing clock signals. These clock signals determine the SPS-4 synchronous links data rate.

The synchronous control interface includes a V.35 and X.21 (DCE or DTE), 25-pin, D-type female connector via adapter cable.
