Some of the handbooks listed here below may not be available on the issue date of this Handbook. This handbook is divided into the following main topics as described in the table of contents: It contains general information on safety norms, EMC and type of labels that might be affixed to the equipment.
Open the circuit by switching off the line switches. If that is not possible, protect yourself with dry material and free the alcate from the conductor.
Mouth to mouth resuscitation method Lay the patient supine with his arms parallel with the body, if the patient is laying on an inclined plane, make sure that his stomach is slightly lower than his chest. The symbols 16600sm statements are enclosed in geometric shapes: The symbols presented in para. Danger level is stated within a rectangular label: Possibility of eyes damage: Therefore, slits or apertures are made to let air circulate freely and allow dangerous gasses to downflow battery—emitted hydrogen.
As stated by IEC Norm. Make sure that the ESD protections have been replaced and after having terminated the maintenance and monitoring operations.

Most electronic devices are sensitive to electrostatic dischargers, to this concern the following warning labels have been affixed: Cautions to avoid possible equipment damage are marked by the following symbol: The above reference numbers are detailed on Table Each handbook is identified by: It allows to multiplex in the time domain up to 4 client signals into one single 2.
The system can be managed either by a Personal Computer through the F interface or by a Network Management System through the Q interface. The equipment SM can be utilized in local, alcayel and metropolitan networks configured for standard plesiochronous or synchronous systems. The product can be suitably employed on linear, ring and hub networks and on protected or unprotected line links.
The Equipment Shelf front view is illustrated in Figure Furthermore, for any item the position and the maximum quantity that can be allocated inside the subracks are indicated allcatel. It is the main shelf of the equipment, also with the back panel Mandatory unit. Note Explanation The board is used to interconnect distances less than approximately 2Km intra—office applica- tion The unit is one slot wide and must be equipped with SFP optical module.
Refer to Figure Note Explanation The unit can be equipped with one 1. This module is not operative in current release. Note Explanation Up to 2 alcatle these modules are inserted on the following cards: Only one of these modules can be inserted in the ATM matrix 4X4.
With the MM1 module must be ordered also the specific patch cord in order to reach the multi- mode charachteistics 50um patch cord or 62 um patch cord.

The functions carried out by the unit can be splitted into the following sub—systems: Connections sub—system see paragraph 3. The functional blocks in this description are similar to that utilized in the Craft Terminal application.
For each port the description is subdivided in two part: Side A to Side B description: The following alatel are associated with each PDH port.

The received line signal is Aalcatel coded. A decoder on the physical interface decodes the signal to NRZ no return—to—zero format. This paragraph has been introduced as an aid to the understanding of the terms used for the Termination Point T. These TPs can be accessed and managed by the operator for performance monitoring purpose.
The REI information is recovered. Low Order Path layer: Side B Figure High Order Path layer: QoS capabilities, variable service rates and traffic congestion management. The system is modular and the plug—ins can be chosen according to the specific application the optical multi—service equipment needs to manage. ATM networks are connection oriented. This 1660am provides summaries of ATM protocols, services, and operation.
ATM transfers information in fixed —size unit called cells ; each cell consist of 53 octets, or bytes. An ATM cell header can be one of two formats: The uni—directional point—to—multipoint ATM connection is supported alcagel the Spatial cell copy to different interfaces and Logical cell copy to different flows on the same interface Multicast feature of wlcatel ATM switch.
In all those scenarios the Provider can take great advantage of the distributed switching functionality for optimizing the transmission resources avoiding wasting capacity not effectively used by the paying traffic.
Label Value 20 bits. The basic concepts for the ISA—PR traffic management at all tributary aalcatel are described in the following and depicted in Figure Classification may occasionally result in a decision to discard the packet because it is not valid or does not belong to any of the provisioned EVCs; The rationale for using the Fixed CoS criterion is mostly Customer Equipment inability to support any of the other criteria.
Policing ISA—PR implements policing to enforce traffic parameters as contracted between the customer and the provider. Policing supports all the three modules specified by MEF; i.

Buffer Management Buffer Management maintains packet memory, structured into multiple queues each queue serving a particular destination and CoS; i. It also maintains various queue fill level thresholds to maintain priorization between CoS, prevent any queue from monopolizing the memory and provide triggers for load balancing.
Load balancing packets are issued after a fixed number of yellow bytes is delivered from a channel. Ingress summary Figure MEF policer Discard Packets output to ring: It involves no extensive classification and no policing. Per packet decision by ADM may result in either: Bottlenecks are convergence points in the ring that might be congested when traffic load increases. There are both Ingress and Egress bottlenecks. This allows for the provisioning of multiple, segregated customer networks over the Service Provider infrastructure, creating a Virtual Private Network VPN for each customer.
Packet protection and QoS assurance in multiring network: The CE dual homing consists in a CE connection to two nodes in a ring for protection of the access interfaces. This protection is described in the following Figure The board acts as a gateway towards the SDH network.
The client sink termination function adapts the client interface; all the payload frames received are stored into input buffer queue. The source SDH adaptation function draws the frames from the memory emptying the cluster and making it available again; Different Ethernet interfaces types can be used at the termination ends: The Core Header, made up of 4 octets, supports frame delineation procedures and essential data link operations functions independent of the higher layer PDUs Protocol Data Unit.
When an excessive traffic is received, a control mechanism can be used to slow down the transmitter avoiding a packets loss. Three different control options are used: As you can see from Figure When a failure occurs inside the network, unavailable paths are not used and traffic is kept by using the remaining available paths.
Herebelow is given an example of the end to end delay; it is the sum of the following values: Gbit Ethernet rate adaptive unit refer to paragraph 3. It immediately follows the preamble pattern and indicates the start of a frame.
It can be achieved in two different ways using: Ethernet traffic profile is typically bursty and the mean throughput is less than the peak rate.
