> In the 7302 ISAM we use the XD modular rack equipment practice, i.e. the XD LT shelf and the splitter shelf is used. > Three rack configurations are defined based on a standard ETSI rack (2200mm x 600mm x 300mm): 7302 ISAM rack with one LT shelf/splitterless shelf · one 7302 ISAM top rack unit (TRU): ATRU-Q · one 7302 ISAM XD splitterless shelf: ALTS-T · capacity of 768 xDSL lines, no splitters included 7302 ISAM rack with two LT shelves/splitterless shelves · one 7302 ISAM TRU: ATRU-Q · two 7302 ISAM XD splitterless shelves: ALTS-T · capacity of 1,536 xDSL lines, no splitters included 7302 ISAM rack with one splitter shelf and one LT shelf - “combo deployment” · one 7302 ISAM TRU · one 7302 ISAM XD splitter (SP) shelf: ASPS-A · one 7302 ISAM XD splitterless shelf: ALTS-A · capacity of 768 xDSL lines, splitters included > Note: as each ISAM shelf is a stand-alone unit, there is in principle no extension between subsequent LT shelves in a rack, i.e. in order to grow the capacity of a node, combinations of A, B and C are possible knowing that each LT shelf will contain its own aggregation function and its own (external) interfaces.

> This eXtreme Density ETSI shelf is a splitterless shelf with front access and backpanel architecture: • NT slots: NT-A and NT-B (for NT redundancy). • NT I/O slot: to insert the NT I/O applique board. • ACU slot: for the ACU card – also used in ASAM. ACU performs alarm management of the shelf • LT board area: 16 slot positions where LT cards are inserted (48 ports XDSL / 24 ports SHDSL / 24 ports VDSL. In the future also 48 port SHDSL and VDSL cards will be supported) POLT and IVPS cards can also be inserted in the LT area (ISAM-V) • 1 SMAS slot: for the SMAS (System Mac Address Storage) card, contains a remote inventory PROM that contains the MAC address(es) of the system • 1 fan unit with or without dust filter. • The upper part of the shelf is referred to as the connector area (also see one of the following slides). > 16 LT boards in one sub-rack and only one sub-rack in one ISAM system means that the max number of xDSL lines that one ISAM system can support is 48*16=768 lines. > The ALTS-T has no splitter area. The splitter function can be done in the same rack or in another rack (external splitters).

> The connector area contains: • TRU interface (50 way D-sub connector): to connect the subrack to the top rack unit. • extender interfaces (26 way connector, not used in ISAM) • interfaces for xDSL: 24 lines per connector, for the LT board immediately below. The connectors used are 48 CHAMP connectors: via these connectors, the xDSL is brought into the shelf. One connector contains 24 pairs. Therefore we need 2 connectors for each board/slot position • remote craft terminal interface (9 pin connector): will allow for remote management via a Craft Terminal through a permanent connection to the ASAM subsystem This can be a modem connection (see drawing) REMARK: the CT connector on the ACU board is DCE type and the CT connector mentioned here is of DTE type (modem = DCE) See also above • power plugs

ALTS-T – PLID switches

splitter shelf (ASPS-A) does not have PLID jumpers. in case a splitter shelf is equipped, the next splitterless shelf (ALTS-T) in the rack is considered as “subrack 1”.

9

> The Physical Location Identification Switches (PLID) identify the position of the subrack/shelf in the ASAM. Depending on the shelf type (LT or combo) you have 2 or 3 per rack! > The PLID jumpers are located on the ASAM back-plane behind the NT board (see slide). •

SR-ID0 → SR-ID2: identifies the position of the subrack inside the rack.

•

R-ID0 → R-ID3: identifies the position of the rack within the DSLAM.

•

R-TYP0 → R-TYP3: identifies the type of DSLAM to the AWS.

> The ALTS-T subrack provides the PLID setting. This requires 21 PLID bits for extreme density equipment. > PLID setting is done on the backplane. Nine bits (SLOT-IDxx, BP-TYP) are fixed by the backplane lay-out, the other twelve (SR-IDxx, RIDxx, R-TYPxx and ACU-EN) are altered at the installation with jumpers.These jumpers are placed on the backplane in two columns between the ACU and the NTA slots.

> The ARAM-D (4-LT shelf) has the following front-accessible slots: > GFC slot: The General Facilities Card (GFC) is mounted on top of the shelf. In case of the ARAM-D, the GFC provides power input and filtering, fan control, SMAS functionality, external alarm collection, a craft interface and Test Access Port connectors. In the case of the ARAM-D shelf the GFC functionality is provided by the PWIO board. > In the slot beneath the GENC card needs to be inserted - alarm control and host expansion interface unit on the 7330 ISAM FTTN. > NTA and NTB slot: These slots can be equipped with the standard NT board types on the 7330 ISAM FTTN host shelf. Additional NT I/O interfaces are located on the GENC card. The component side for these NT boards is UP. If the shelf is used as a slave, then a single slave expansion card must be inserted at the position of NT A. The NT B slot must be covered with a filler plate. > LT1 through LT4 slots for LT units: The LT boards supported are e.g. EBLT-C, EBLT-E, EBLT-K (48 ports multi-DSL) and EVLT-A, EVLT-C (24 ports VDSL) > LP1 through LP4 slots for appliques: The splitterboards supported are e.g. AVPC-A, HCUT-C, HLPC-H, HLPC-J and VPSC-D > Fan slot: only the NTs, combo I/O card and LTs are cooled directly by the fan unit. The LPs and the GFC will only receive some limited cooling. The fan unit for ARAM-D exists out of a four-fan assembly, the AFAN-L. > The ARAM-D shelf supports MTA.

This is an 8-fan fanunit with or without dust filter. Only one dust filter is needed per rack. > The top rack unit (TRU) is the unit providing the power interface between the office power plant and the subracks. It is also the interface between the office alarm system and the rack equipment (including up to five customer defined external alarms) and displays the rack alarm conditions. > Fan unit: One fan unit (AFAN-H) provides forced air cooling in the subrack. The fan unit is a field replaceable unit in the subrack fan area, it plugs directly into the backplane. > There are two variants, one with dust filter and one without dust filter. The fan unit of the subrack in the lowest rack position must always contain a dust filter.

> The TRU is installed in the top position of the rack and is always cabled for two subracks, even if the configuration only requires one subrack . This is due to anticipated difficulties in adding cables after initial installation. > The top rack unit terminates the feed(s) of the office battery branches A and B and distributes the power to up to two subracks via individual feeds and via circuit breakers. > In an XD rack, the top rack unit (ATRU) distributes fused -48 Vdc or -60 Vdc power to all the subracks and fan units via two redundant branches. It interfaces between the DSL equipment and the Central Office alarm system. > The ATRU-Q contains the following functional blocks: • Front panel with circuit breakers and alarm display • termination for external wiring • alarm and control boards with interface to internal ACU boards and external CO alarm systems.

> The slide above shows the 7302 ISAM’s XD system architecture. > The 7302 ISAM XD consists of a set of 16 subscriber line termination (LT) boards, 1 or 2 network termination (NT) boards, 1 network termination I/O board, 1 alarm control unit (ACU) board, all located in an eXtreme Density (XD) splitter-less shelf ALTS-T. > The NT board contains an integrated aggregation function with a total switching capacity of 24 Gbps which is commonly referred to as the service hub (SHUB). > Actually there are two ethernet switches on the NT having a capacity of 12 Gbps each, which means the total switching capacity is 24 Gbps, corresponding with 16 GE ASAM links + 8 Ethernet links. > Depending on the NT card type you will have 7 external Ethernet links + 1 control link or 8 external Ethernet links. In case of 8 external Ethernet links the connection of the SHUB with the control and management function is no longer done via ethernet. This way the ISAM has an additional network link (true e.g. for ECNT-C Æ see later in this presentation) > Whether a clock function (BITS) interface is present on the NT or not will also depend on the variant of NT card. > The 7302 ISAM XD does not have a dedicated power unit (the interface point to the external DC power supply systems and provides power). On the shelf itself there are so called fast-on connectors for providing power supply coming from the top rack unit (TRU). The power signals BATA, BATB and BATRET are distributed via the backplane and feed the plug-in units and fan units installed. > You do not find the TAU module on this drawing, although ISAM XD equipment practice provides this functionality. An RJ45 for test access (connection to TAU) is present on the NTI/O ( see later), but the TAU module itself is on a TAUS-card which physically needs to be inserted in the splitter-shelf.

> All the data that passes through the 7302 ISAM will always pass through the NT. It is the 24 Gbps Ethernet aggregation switching function, i.e. the service hub residing on the NT that is responsible for the data forwarding towards the Ethernet aggregation network. > Another functionality of the NT-board is the control plane of the 7302 ISAM required e.g. for maintenance and operations, remote inventory information and shelf management. It provides management interfaces (LAN, CRAFT, RCRAFT) to the outside world and control interfaces towards the line termination (LT) boards and the network termination I/O. > On the NT resides an interface and media conversion block which provides 3 or 4 (depending on NT card type) external Ethernet interfaces. These interfaces are primarily intended to be used as subtending and/or network links or for a directly connected user. In case optical interfaces are needed the media converter on the NT converts the electrical signal coming from the service hub into an optical signal. > Whether a clock function (BITS) interface is present on the NT or not will depend on the type of NT card. > NT redundancy is supported > The NT has the same functionality in the 7330 ISAM FTTN host shelf as in the 7302 ISAM. > The NT in the 7330 FTTN host shelf however, will also provide the different functionalities for the remote units connected to the 7330 FTTN host shelf.

> ECNT-A Æ NT board with integrated SHub. Provides three electrical FE, electrical GE or optical GE links on the front panel. > ECNT-C Æ NT board with integrated SHub. Provides four GE links on the front panel: three GE optical + one 10/100/1000Mbps optical/electrical (selectable) > Besides providing network termination, the ECNT card performs Ethernet switching and control functions for the 7302 ISAM-XD and the 7330 ISAM FTTN-XD, as well as for any connected 7330 REM. It handles the xDSL, the shelf, and the switching data path. > The ECNT card handles high-bandwidth IP services for xDSL subscribers by providing a 24 Gigabit Ethernet switching fabric (service hub). In the downstream direction, high-bandwidth IP services enter the network termination side of the 7302 ISAM or 7330 ISAM FTTN over connectivity at the ECNT card or through the NT I/O (7302 ISAM) or GENC card (7330 FTTN). > The ECNT card switches the Ethernet IP traffic. The appropriate packets for each connected xDSL subscriber are then forwarded over the backplane to the LT. In the upstream direction, the ECNT card receives Ethernet packets from the LTs over the backplane. The ECNT card either switches the Ethernet packets to the high-bandwidth IP services network or passes them to the NT I/O (7302 ISAM) or GENC (7330 ISAM FTTN) card. > For expansion configurations with REMs, the NT on the 7330 FTTN host shelf switches traffic destined for remote subscribers to expansion ports on the GENC card via the shelf backplane. Traffic from remote subscribers is forwarded to the NT over the expansion links that connect to the GENC card on the host shelf. > The ECNT card supports inband or outband management traffic received through its connectors. Local management (craft terminal) is supported by the ECNT card through craft connections on the AACU (7302 ISAM) and PWIO (7330 ISAM) cards. The NT on the FTTN host shelf is used to manage REMs which cannot behave as standalone units.

The six connectors on ECNT-A are logically grouped into three pairs of one electrical connector and one optical connector each. Only one of the two connectors in a logical pair can be active at any one time. For example, if you are using the optical connector in the first pair, then you cannot use the electrical connector of the pair until you disconnect the optical connector for the pair. If ECNT-A cards have been installed for NT redundancy, a total of six NT connectors are provided, with three being active. > ECNT-C: • port 0 Æ 10/100/1000 Mbps electrical or optical • port 1,2,3 Æ 1GE optical only! > SFP (Small Form factor Pluggable units) for NT & NT-I/O or GENC: optical modules exist for GE and FE.

SMAS

37

> On the SMAS-card the MAC-addresses of the NT/service hub that will be used for management, are stored. When the system boots, the service hub gets its MAC-address(es) from the SMAScard. The 24 MAC-addresses for each port on the SHUB, are stored on the PROM of the SMAScard. The reason why the MAC-addresses are stored on a separate card, that only contains a remote inventory of the ISAM shelf, is that if it would be on the NT and the NT would fail, the network might have trouble. The MAC-address will have been learned and if you replace the failing NT by another one, a new MAC-address would have to be learned. What if the old arp-entry first has to age? (e.g. a delay of 5 minutes). With the MAC-addresses on the SMAS card, any NT will get the same MAC-addresses after replacement, so the switches in the network don’t need to learn any new MAC-addresses from the NT’s. > The SMAS card as depicted on the slide is only used in 7302 ISAM CO XD. • For 7330 FTTN XD, the SMAS functionality is integrated on the PWIO card.
