OC3 Electrical/Optical – A mixing of SDH and Data Services is possible by inserting the 4xANY board in the 1660SM subrack. It allows to multiplex in the time domain up to 4 client signals into one single 2.5Gb/s optical channel (server signal).
Page 66
1660SM equipped with ISA plug–in cards give telecom operators a new generation modular platform for multi–service SDH transport and further strengthen Alcatel’s leading position in the supply of optical multi–technology transmission networks.
Page 67
When 1660SM is used as Add/Drop Multiplexer , mixed STM–N ports can be used in the same configuration thus allowing to manage in the same equipment and at the same time STM–1 , STM–4, STM–16 and STM–64 rings (multiring).
Page 68
The system can be managed either by a Personal Computer through the F interface or by a Network Management System through the Q interface. Moreover, the 1660SM can work as a Mediation Device for Alcatel NE accessible through Q2/RQ2 interface. In this way, it can be possible to transport information about alarms and configurations of PDH and/or Access Systems to/from a centralized TMN using the standard SDH DCC network.

3.5 ISA – ATM management sub–system 3.5.1 ATM ( Asynchronous Transfer Mode) basic Asynchronous Transfer Mode (ATM) is an International Telecommunication Union Telecommunication Standardization Sector (ITU–T) standard for cell relay wherein information for multiple service types, such as voice, video, or data, is conveyed in small, fixed–size cells. ATM networks are connection oriented. This chapter 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. The first 5 bytes contain cell–header information and the remaining 48 contain the “payload” (user information). Figure 108. on page 226 illustrates the basic format of an ATM cell. 8 Bits HEADER (5 bytes) 53 Bytes...

An ATM cell header can be one of two formats: UNI or the NNI. The UNI header is used for communication between ATM endpoints and ATM switches in private ATM networks. The NNI header is used for communication between ATM switches. Figure 110. on page 228 depicts the basic ATM cell format, the ATM UNI cell–header format, and the ATM NNI cell–header format.
Up to 32 TPs can be configured among VC–4, VC4–C, VC–3, VC12, E3 and E1. If more capacity is needed more than one ATM board in a single 1660SM can be used. The overall ATM Switch functional model is compliant to ITU–T I.731, I.732, ETSI EN 300 417–1–1/2–1, af–tm–0010.002.
3.5.2.1 ATM point to point and point to multipoint connections Uni–directional and bi–directional point–to–point ATM connections (VPC and VCC) are supported. Uni–directional (for broadcast or drop&continue usages) point–to–multipoint ATM connections (VPC and VCC) are also supported. The uni–directional point–to–multipoint ATM connection is supported via the Spatial (cell copy to different interfaces) and Logical (cell copy to different flows on the same interface) Multicast feature of the ATM switch.

MPLS routers have only to select the “next hop” to which forwarding the incoming packets, by looking the top label. PR_EA (Packet Ring Edge Aggregator) is an Alcatel mark indicating a system that is able to aggregate, at the edge of the MPLS network (ring topology), many mpls packets communications.
The Alcatel MPLS system can manage packets data streams transported over “local” Ethernet FE or GE (Fast Ethernet, Gigabit Ethernet) and “remotized” ethernet over GFP/SDH; the packets are identified and classified with a first label (by inspecting the ethernet frame header), marked again by the label switching router with a second label, and then sent into the MPLS network, aggregated and encapsulated into PPP/HDLC/SDH frames.

The following are the main functional blocks implemented in the PR_EA Unit: • SDH–MAP It provides to deassemble the SDH virtual containers (toward MPLS direction), removing the SDH OverHead, and to assemble them toward SDH direction, thus “loading” and “unloading” the packets to/from the SDH frames (refer to ITU–T rec.

• QUEUING MANAGER It provides to monitor the load of traffic in the local router, and to take measures for preventing the congestions, supported by the intra–board MPLS microcontroller. The priority management is based on the ethernet SLA (Service Level Agreement), three types of QoS (Quality of Service) are available: Best Effort bandwidth (BE–BW), Min–BW with regulated bursts, Guaranted constant BW.

3.7 ISA – PR Subsystem 3.7.1 PR Generalities The role of the ISA–PR (Internetworking Services Architecture – Packet Ring) functionality inside 1660SM is to provide a shared carrier–class Ethernet Packet Ring: • embedded physically into the SDH infrastructure, in which case the embedded Packet Ring is provided in a flexible manner over SDH Virtual Containers (VC–4–Xv)
3.7.2 PR in 1660SM The ISA–PR is a self contained, independent sub–system operating in the OMSN 1660SM chassis, it is not connected to the rest of the node from a system perspective except for the drawing of power from the backplane;...

Figure 125. Each ISA–PR port card requires two chassis slots. The ISA–PR may be plugged into any PORT slot in the 1660SM, apart from the slots dedicated to Controller and Switch cards. Multiple ISA–PR sub–systems may be installed in a single 1660SM system.
Page 251
Main functional aspects of the ISA–PR: 1660SM when equipped with ISA–PR sub–system will allow point–to–point and multipoint–to–multipoint Metro Ethernet connections between routers or switches through SDH, as depicted Figure 14. The Packet Ring maps Ethernet over MPLS over POS and shares the bandwidth between hundreds of Ethernet traffic flows according to the defined SLA.
ISA–PR Traffic Management ISA–PR supports Ethernet traffic management, fully compliant with the MEF specifications. The basic concepts for the ISA–PR traffic management at all tributary ports are described in the following and depicted in Figure 126. and Figure 128. Figure 126. provides a high level overview of the traffic flow and processing in the ISA–PR series modules.
Page 253
3.7.2.1 Ingress processing Classification Every packet entering through a tributary port is classified to identify the EVC it belongs to, and its CoS. 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;...
Page 254
ISA–PR may be provisioned to use the following criteria to determine the CoS of the packet: • 802.1p – IP TOS/DiffServ – MPLS Exp – MPLS Tricolor scheme. – Fixed CoS; i.e. independent of any indication within the packet. 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.e. policing per: • • • EVC.CoS The standard set of attributes for each of the model is above is •...
Page 256
Buffer Management Buffer Management maintains packet memory, structured into multiple queues each queue serving a particular destination and CoS; i.e. three queues per destination. 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 128. summarises ingress processing. MEF policer Discard Packets output to ring: Packets are output onto the ring into the appropriate Virtual trunk (VT) for the CoS & Destination node/port Packet analysis(B): Policing: Packets are put into queues MEF policing with CIR+ based on header priority and EIR SLS.
Page 258
3.7.2.2 Egress processing Egress processing is much simpler than Ingress processing. It involves no extensive classification and no policing. The ADM function selectively drops packets into the node, based on their MPLS labels and identifiers their EVC and CoS. Per packet decision by ADM may result in either: –...
Load Balancing In order to prevent congestion in the ring each ISA–PR monitors the traffic, identifies congestion conditions, communicates its status to other ISA–PR and responds to congestion reports by other ISA–PR. This set of functions is collectively referred to as ”Load Balancing”. Both ADM and Buffer Manager participate in Load Balancing.
Bottlenecks Each ISA–PR monitors the traffic traversing it on a number of ”bottlenecks”. Bottlenecks are convergence points in the ring that might be congested when traffic load increases. There are both Ingress and Egress bottlenecks. Figure 130. Bottlenecks Congestion Indications Whenever a bottleneck is congested the node will notify the other nodes in the ring of the congestion by sending a ”congestion indication”.

This allows for the provisioning of multiple, segregated customer networks over the Service Provider infrastructure, creating a Virtual Private Network (VPN) for each customer. 1660SM 1660SM Figure 132.

3.8 ISA – ETHERNET management sub–system 3.8.1 LAN to LAN transport service OMSNs can be equipped with Ethernet units to allow LAN to LAN service as a point to point connection between two routers or switches through a SDH network, as depicted Figure 145. on page 277. The board acts as a gateway towards the SDH network.
3.8.2 LAN to LAN functional description The functional block diagram of a LAN to LAN service is shown in Figure 136. 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;...

According to the type, the GFP frame format consists of a Core Header, a Payload Header, a Client Payload field and FCS field. 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). The GFP Core Header consists of the following fields –...
3.8.3.2 Flow control To avoid buffer saturation probems at the termination end, flow management is very important. 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 140. on page 270, the output control is performed at the output port only when Extended GFP is used. When the output buffer of Port B crosses a fixed threshold of – 272 frames, when VC–3 concatenation is used (N x VC–3) –...
When the Packet Concatenation is used, each Ethernet frame is not shared among different paths (VCs) of a certain pipe as in Virtual Concatenation mode; but each message is dispatched on a single path/VC of a certain pipe. When a failure occurs inside the network, unavailable paths are not used and traffic is kept by using the remaining available paths.

Gbit Ethernet (rate adaptive) unit (refer to paragraph 3.8.5.2 on page 279) 3.8.5.1 10/100 Mbit/s Ethernet unit 1660SM can also be equipped with 10/100 Mb/s Ethernet unit to allow LAN to LAN connections as a point to point connection between two routers or switches through an SDH network, as depicted Figure 145.
This is a typical problem of resource allocation where in one side there are up to 25 VC–n transport structures on the other side there are 4 tubes of STM–1 capacity, and the Operator has to find the mapping VCn–tube which best fits the available resources (622 Mbit/s).

Ethernet MAC Frame and GFP Frame fields: – Preamble: the preamble is a 7–octet field that is used to allow the PLS (Physical Signaling) circuitry to reach its steady–state synchronization with the received frame’s timing. – Start of Frame Delimiter: the SFD field is the sequence 10101011. It immediately follows the preamble pattern and indicates the start of a frame.
3.8.5.2 Gbit Ethernet (rate adaptive) unit The task of the Gigabit Ethernet functionality inside 1660SM is to carry Gigabit Ethernet packets over SDH Virtual Containers. It can be achieved in two different ways using : “Gigabit Access card” + “10/100 Mbit Ethernet board”: only two Gigabit interfaces are supported.
Ethernet traffic profile is typically bursty and the mean throughput is less than the peak rate. If the board is into an enhanced slot of 1660SM the back panel throughput is of 1.2 Gb/s instead of 622Mb/s, this determines that the maximum number of VC–4 mappable to the Gb/s Ethernet Interfaces is 8 instead of 4.
3.9 ISA – ES (Ethernet Switch) 3.9.1 General Today’s evolving telecommunications services environment is highly competitive. There is a growing demand from Enterprise customers for simple, wide–area Broadband Data services which meet their needs for plentiful, competitively priced and flexible connectivity. Historically the success of Ethernet as the predominate technology within the Enterprise infrastructure, has been driven by very low capital and operational costs, the high degree of flexibility offered by the technology and importantly its easy of use –...
Ethernet Virtual Private Line EVP–Line service connects two ports of a client between each other (using bridging mode). Traffic originating from one Customer Port is classified and forwarded accordingly to the other end. The service emulates an Ethernet ”wire” which actual bandwidth is determined by the SLA and by network load.
Broadband access In this service, a number of customers are connected to a common Aggregate Port (e.g. typically connected to an ISP point of presence) Traffic is only delivered from individual Customer Ports to the Aggregate Port. Broadband Access can distinguish between various customers’ traffic at the Aggregate Port using VLAN tags.
3.9.2 ISA–ES series modules ISA–ES series modules provide ETH 10/100/1000 interfaces connectivity for LAN based clients premises inside the metro area. Beyond mapping ETH flows onto the SDH metro network by means of standard mechanisms (as specified in ITU G.7071, ITU G.7042 and ITU G.707) the ISA–ES series cards introduce wire speed classifying, policing and scheduling capability empowered by carrier class Ethernet switching engine.
The number to the right of the ISA–ES series card gives that amount in VC–4 equivalents. Hereafter are reported the available trunking capacity for each of the ISA_ES series cards: – ISA–ES1 has 1 VC–4 of bandwidth available – ISA–ES4 has 4 VC–4 of bandwidth available –...

[2] Traffic classification ISA–ES series module can classify ETH traffic according to a wide set of standard specified criteria in order to provide a feature reach set of capability. Each classified traffic is referred in the next paragraphs as a classified flow. Classification criteria are the following: •...
Page 291
Through the specification of per flow traffic parameters the ISA–ES series modules can support the following SLAs: Guaranteed SLA Typically serves High priority traffic for mission critical applications that require loss–less delivery and minimal delay. Guaranteed SLA denotes BW (CIR = PIR > 0 in 100Kbps increments), which is always available regardless of any congestion conditions.
WRED The packet drop probability is based on the minimum threshold, maximum threshold, and mark probability denominator. When the average queue depth is above the minimum threshold, RED starts dropping packets. The rate of packet drop increases linearly as the average queue size increases until the average queue size reaches the maximum threshold.
[5] Switching and forwarding ISA–ES series modules are based onto a carrier class Ethernet switching engine with auto learning bridges according to IEEE 802.1ad. This engine is either wire speed performing (all the functions are performed in hw) and highly flexible and configurable.
Multiple customers per NNI port The ISA–ES series modules allow a single NNI interface to be used for different customers while guaranteeing high levels of segregation, security and per customer QoS ability. ISA–ES series modules allow ETH frames to be tagged before being sent at the NNI interface. The modules have full VLAN tag agility in the sense that VLAN tags can be pushed, swapped and popped by the cards.
3.10 4 x ANY HOST C subsystem The unit is able to perform time division multiplex/demultiplex of client channels. The client streams are mapped in 16 virtually concatenated VC–4s according to a proprietary–mapping algorithm. Provisioning parameters and alarm collection are managed through two control interfaces. The board has a highly modular fabric consisting of a housing card that can accommodate up to 4 modules, one for each aggregated traffic.

SQUELCHING FUNCTION The Squelching function is activated when a node that carries Drop/Insert streams, remains isolated because of a double failure. In this case to avoid misconnections on the AU4 involved in MS SPRING protection, an AIS signal will be inserted on Low Priority streams transmitted from the nodes adjacent to the isolated one.
MS – SPRING Interworking When a 2f MS–SPRING is interconnected with another ring (either SNCP/I or MS–SPRING), the interconnection of the two is performed by connecting two nodes per ring with HVC connections, as shown in Figure 216. on page362. Each VC4 that has to cross the ring boundary (only HVC level ring interconnections are considered here) must be output by two nodes, one of which, the Primary Service Node (PSN) drops it and continues to the Secondary Service Node (SSN).
