Focus in this presentation is copper delivery: 7302 and 7330 ISAM

Solutions for different environments

7302 ISAM (multi-DSL, VDSL, SHDSL)

7330 ISAM FTTN (multi-DSL, VDSL, SHDSL)

Access Manager (ISAM) family supports a range of deployment practices including:

7302 ISAM for DSL-focused deployments from large COs

7330 ISAM fiber to the Node (FTTN) for smaller COs or serving area interface locations and remote outside plant locations

7330 ISAM FTTN Remote Expansion Module (REM) for multi-dwelling units and small remote outside plant locations

7330 ISAM Remote aggregator (RA).Providing 2x10GB uplinks to connect REMs/SEMs.

Onto the 7330 ISAM FTTN and/or RA we can connect expansion modules to it. These expansion modules are equivalent to to adding remote LT unit(s) to the host

- 7356 ISAM FTTB Remote Expansion Module (REM) (based on FD HW) for multi-dwelling units and cabinets. This provides an extension of ISAM deployment into FTTN & larger FTTB

- 7357 ISAM FTTN Sealed Expansion Module (SEM) for multi-dwelling units and small remote outside plant locations. Extension of ISAM deployment into FTTC. FTTC/B complement to cabinet deployment – reach 100% coverage

Unlike the 7356 and the 7357, which are remote LT unit(s), the Alcatel-Lucent 7354 Intelligent Services Access Manager (ISAM) Fiber-to-the-Building (FTTB) Remote Unit (RU) is a stand-alone unit. It is compact full-service IP access node for MDU and

7330 ISAM FTTN

7330 ISAM RA

7356 FTTB REM

The 7330 ISAM FTTN (Fiber To The Neighborhood) has the same feature set as the 7302 ISAM, except for the number of lines attached (scalability).

FTTN system is a compact remote IP DSLAM designed to address the growing need for a deep fibre access solution

Targeted market:

small number of lines

remote deployment

Apart from the 7330 FTTN Host CO device, which can still terminated DSL subscribe lines directly (allowing from 4 to 10 LTs, depending on equipment practice), there is now also the 7330 RA (Remote Aggregator). The 7330 RA only supports the aggregation of REM and SEM devices (not direct DSL termination any more).

Remark: 7330 FTTN has 24Gbps switching capacity, whereas the 7330 RA has a capacity of 44Gbps

Logically, the 7330 FTTN host and the REM(s) behave as one single ISAM. The REM has splitter and LT functionality and is managed as if it is a LT board inserted in the FTTN host.

On the 7302 you have the possibility to have FE optical interfaces via one of the available NT I/O cards on XD hardware (ECNC-B) see later. This card however is not insertable in the 7330 FTTN unit. Therefore FE Optical network links are not possible in 7330 deployment to the network. Via the NELT card (see later), FE towards the end-user is supported on the FD equipment practice.

At the user side, the ISAM terminates ADSL/ADSL2/Re-ADSL/ADSL2+, SHDSL & VDSL links. It is also possible to terminate a limited number of Fast Ethernet or Gigabit Ethernet links (FE/GE).

At the network side, the ISAM terminates GE or FE links. In case of more than 1 FE or 1 GE, Ethernet link aggregation can be used. The Ethernet links can also be connected to 1 or more Ethernet switches. The Ethernet switches forward the frames over the Ethernet based aggregation access network until it reaches the IP Edge Router of the corresponding network service provider. At the IP Edge Router, the frame enters the IP backbone of the network service provider. The ISAM can also be connected directly to the IP Edge router, in which case the Ethernet aggregation network is reduced to 1 or more parallel Ethernet links.

At the user side it is also possible to connect subtending IP-DSLAMs. It is possible for example to connect ISAMs in cascading model. The last system can be any IPDSLAM, e.g. an ISAM/FTTN, or an Alcatel ASAM with an Ethernet uplink (FENT or GENT) or any other kind of DSLAM with Ethernet uplink.

EMAN node

The cascaded topology allows installing shelves and racks in a chain. The so-called subtended system is connected to the main system through a subtending interface (such as Fast Ethernet and Gigabit Ethernet) and shares the network interface of the main system. Depending on the exact purpose (expanding to large DSLAMs in certain central offices and/or increasing coverage in the network by positioning DSLAMs at as many locations as possible), the subtended systems can be located near the main system (=co-location) or at a remote location.

There is no strict limitation on the number of subtended ISAMs. Each ISAM has its own free running clock. Of course, the available and necessary bandwidth has to be taken into account.

Note that also other types of DSLAMs can be cascaded of an ISAM via Fast or Gigabit Ethernet interfaces: 730x ASAM, 730x ASAM-c, 7324 RU, non Alcatel DSLAMs.

Sometimes, the cascaded topology is also referred to as the daisy-chained topology.

A 7302 ISAM can also be used as an aggregation multiplexer to collect traffic from multiple directly connected subtended DSLAMs. Rather than adding subtending levels, we then create a star architecture. Again, other DSLAMs can be subtended through FE/GigE and the subtended systems can be located near the main system or not.

It is possible to put the ISAM in a ring architecture, i.e. a special case of the cascading architecture where the last system of the chain has yet another uplink to the EMAN network as well.

The maximum number of devices in the ring is 8, because of delay when using RSTP. Such a limitation does not exist on STP, but due to the long time it takes for STP to adapt to changes in the topology, STP should not be used.

Another option is to use MSTP, where it’s possible to have different topologies for different VLANs. See chapter on Spanning Tree Protocol, later.

---

The Intelligent Services Access Manager (ISAM) is a frame based Digital Subscriber Line Access Multiplexer (DSLAM), i.e. a digital subscriber line (DSL) access multiplexer which is based on a (ethernet) frame forwarding architecture in a packet aggregation network.

Different types of ISAM do exist, but conceptually they have the same building blocks. The mapping of functional blocks to hardware modules depends on the equipment practice chosen.

Data forwarding in the ISAM is accomplished by interworking functions (on LT’s) and/or an aggregation function (on the NT): both of them include a forwarding engine.

The core of the ISAM is the 24 port Ethernet service hub (shub or aggregation switch), providing a 24 Gbps switching capacity.

The line termination module terminates subscriber interfaces and provides the interworking and aggregation function towards the service hub.

The LT-module actually consists out of 2 functional submodules. The transport function ant the IWF(Interworking function).

The transport function varies with the type of access technology used (ADSL, VDSL, SHDSL, Ethernet, ...).

For DSL interfaces, the transport function contains:

the High-Pass Filter (HPF) , separating the DSL portion of the signal spectrum from the narrowband signal (POTS or ISDN)

the DSL modem function, providing the physical layer termination of the DSL signal


The line termination module (cont’d)Transport function On the slide you see that the LT module terminates VDSL or SHDSL (EFM) and below the line termination module terminates xDSL or SHDSL (ATM-based). Depending on the access technology terminated, you will have a different type of LT board.

The IWF handles frame forwarding, including sophisticated filtering and traffic management (QoS), all at the line rate of the transport medium.Internally the ISAM is Ethernet based. As a result of this, the IWF will, in case of DSL interfaces with ATM transport mode, also remove ATM/AAL layer. Line termination modules ( located on LT-boards), are connected to the aggregation function via the ASAM-ports or expansion port the line card can be a separate box (REM) (which doesn’t behave as a standalone node!).Links between aggregation function and LT-boards are called ASAM-links. Links between aggregation function and REM are called expansion-links.

The remaining ports on the service hub can be allocated to uplink interfaces (connecting to the upstream E-MAN), to subtending interfaces (connecting to downstream Ethernet DSLAMs) or to user Interfaces (connecting directly to 802.3 subscribers).

IEEE 802.1d STP and IEEE 802.1w RSTP are supported on network ports only.

IEEE 802.3ad Link aggregation is supported on network ports and subtending ports.

The max. number of LT’s and the max. number of uplinks depends on the equipment practice.

The packet processing architecture of the ISAM family is future-safe and specifically designed for multimedia and business service delivery over IP/Ethernet aggregation networks.

The Control and Management function is required for maintenance and operations, remoteinventory information, shelf management. As the name indicates, this functionimplements the management plane of the system and part of the control plane, in particular the part related to subscriber management which is typically not found in an Ethernet switch product. The Control function is distributed over multiple general-purpose processors, managing the system, service hub and LT modules in a hierarchical way.

The ACU (alarm Control unit) module provides collection & distribution of equipment & customer alarms.

The clock module generates the system clock. It consists of a local oscillator which can optionally be locked to an external reference clock (BITS).

The TAU (Test Access unit) function provides access to an external line test head (for Metallic Test Access) and provides control of the MTA relays on the splitter modules.Manages the switching of signals between the MTA ports (located on the PWIO-B) and subscriber lines (connected to appliques).

The Power function is the interface point to the external DC power supply systems and provides power monitoring, filtering, distribution and securing functionality.

The 802.3 Port function provides the physical layer interface for Ethernet ports. Electrical auto-sensing 10/100/1000 RJ45 ports and optical FE/GE ports on SFPs are supported.

Server modules can be plugged into LT slots. Instead of providing subscriber connectivity, they typically provide an auxiliary central processing function, e.g. the ISAM-V IVPS (ISAM voice Packet Server) module, which provides a centralized signalling interface to the call server or softswitch. Server modules are not discussed in this presentation, nor indicated on the drawing. They are discussed in separate dedicated courses.

SMAS module System MAC Address storage.The SMAS module is integrated on a remote inventory PROM that contains the MAC address of the ISAM (NT). Upon booting up of the ISAM, the MAC address is read by the active NT (or the standby NT in case of failure of the active NT). The 24 MAC-addresses for each port on the SHUB, are derived from the system MAC address that is stored on the SMAS PROM

Equipment Practice4

Equipment practice is mainly about the mechanical and electrical aspects of the equipment:

physical dimensions,

number of shelves allowed in a rack,

power feeding,

electro magnetic interference

…

In this course we are covering eXtreme Density equipment practice (XD) as well as Flexible Density equipment practice(FD).

FD equipment practice is the successor of the XD equipment practice.

For both equipment practices, ISAM 7302 and ISAM 7330 FTTN products will be covered.
