Regenerator The OC- regenerator shelf regenerates the OC- optical signal and does not allow access to DS, DS3, or STS- channels. Control shelf Locate the OPC in the TBM control shelf when it cannot be placed in a TBM shelf that handles OC-3/OC- traffic. The control shelf is commonly used in ring systems and OC-3 tributaries. If you locate the OPC in a terminal, linear, or ring ADM shelf, you reduce the number of circuit pack locations available for tributary termination. Hardware options The following hardware options are available: frame and shelf hardware peripheral interface cables filler panels filler cards fiber-storage panel or fiber-splice tray breaker interface panel (BIP) modem S/DMS TransportNode OC-3/OC- NE TBM Vol Rel 4 Standard Feb 00

15 Configuration and ordering -7 external synchronization interface (ESI) required for ring configurations, or network elements that distribute timing Hardware baseline CAUTION Risk of traffic loss Using hardware with a release lower than the hardware baseline causes traffic outages. Check that all circuit packs meet the hardware baseline, before inserting them in the shelf. The hardware baseline is the minimum supported release of hardware for a software release. For information on hardware baselines, call the Nortel Networks Fax-on-Demand Service, Ensure you check all spare circuit packs at this time as well. Software options An S/DMS TransportNode includes one (primary) or two (primary and backup) operations controllers (OPC). The OPC manages the software that makes the hardware operational. Order the following software components separately: software loads software licences Software loads A TBM shelf includes a Right-to-copy certificate. This certificate permits you to load the most recent software version (as of the date of purchase) into the shelf. Software loads are provided on a digital data storage tape (DDS). An installation tape contains network element loads (software and firmware) and an OPC load. Software licences Software licences permit the use of software-based configurations and features. Four types of software require a licence: shelf configuration or application software optional operations, administration, maintenance, and provisioning (OAM&P) software OPC application software port configuration software Ordering Information Rel 4 Standard Feb 00

16 -8 Configuration and ordering Shelf configuration software Every shelf must have functionality software and the standard OAM&P software.

17 - Bay frame and shelf hardware - This chapter describes how to order OC-3 or OC- configuration packages, or individual bay and shelf components. Equipment is identified by product engineering code (PEC). TBM shelf and cooling COP kit (NT7E5AA) The OC- TBM shelf and cooling COP kit (NT7E5AA) replaces the TBM shelves and enhanced cooling required for VTM applications. The TBM shelf and cooling COP kit offers the following advantages: The shelf can be equipped with OC- (NT7E0xx) or OC- VTM (NT7E05xx) optical interface circuit packs allowing either TBM or VTM functionality. Each shelf is cooled as an independent unit. This integrated cooling eliminates the need for extra bay cooling (enhanced transport common equipment shelf NT4K9AC, through-flow cooling unit NT4K8BA and fan modules NT4K7BA) previously required for VTM applications. The shelf occupies 3 mounting spaces. A bay equipped with three TBM shelf and cooling COP kits (NT7E5AA) gains two mounting spaces for optional equipment such as fiber storage panels. The shelf incorporates four NT7E55AA fans, a cable organizer panel (COP), a plugin section, and an air filter drawer. The NT7E55AA fans can be used on OC- or OC-48 shelves. The housing for the fan assembly is plastic rather than sheet metal, making the fans easier to install. Note: OC-48 fans NT8E55AA cannot be used in the TBM shelf and cooling COP kit (NT7E5AA). Bay packages (framepacks) with the TBM shelf and cooling COP kit (NT7E5AA) Bay configuration packages include the following (see Table - for additional details): one, two or three TBM shelf and cooling COP kits (NT7E5AA) breaker interface panel (BIP) (NT7E56CA) Ordering Information Rel 4 Standard Feb 00

29 3- Circuit packs 3- This chapter describes how to order circuit packs for an OC-3 or OC- network element. The equipment is identified by a product engineering code (PEC). Transport Bandwidth Management The number, type, and location of transport interface circuit packs depends on the TBM shelf application: A terminal shelf houses two bidirectional transport interface circuit packs in slots 9 and 0 (one working and one protection). A linear add-drop multiplexer (ADM) shelf houses four bidirectional transport interface circuit packs in slots 5, 7, 9, and 0 (two working and two protection). A network (NWK) ring ADM shelf houses two transport interface circuit packs (NT7E0) in slots 5 and 9, and two ring loopback circuit packs in slots 7 and 0. A VTM ring ADM shelf houses two transport interface circuit packs (NT7E05) in slots 9 and 0. A regenerator shelf houses two bidirectional transport interface circuit packs in slots 5 and 9. Each OC-3 and OC- shelf supports a wide range of DS, DS3, STS-, and OC-3 tributary configuration options. For more information, see System Description, See Table 3- to Table 3-6 for circuit pack ordering codes. Ordering Information Rel 4 Standard Feb 00

30 3- Circuit packs OC-3 interface circuit packs Each OC-3 networking interface is protected on a + basis (one working, one protection). OC-3 optical interface circuit packs are available in two reaches, each with a different system gain: Optical interface System gain (BER = 0 0 ) Intermediate reach (30 nm) Long reach (30 nm) db 8 db See Table 3- for ordering codes for OC-3 networking interface circuit packs. OC-3 interface circuit packs with changeable optical connectors OC-3 interface circuit packs with changeable optical connectors (NT7E0GA and NT7E0GB) provide the same functionality as OC-3 networking interface circuit packs with fixed optical connectors (NT7E0Cx and NT7E0Dx). OC-3 interface circuit packs NT7E0GA and NT7E0GB are compatible with Release 9 software, or later. Circuit packs with changeable optical connectors use a universal adapter to permit use of ferrule (FC), straight (ST) or subscriber connectors. (FC connectors are steel-threaded, SC connectors are plastic snap-in, and ST connectors are bayonet press-and-twist.) Connector types can be changed easily. Circuit packs with universal adapters reduce the number of spares needed and permit easier cleaning. Order circuit packs and optical connector kits separately.

31 Circuit packs 3-3 OC- interface circuit packs Each OC- interface is protected on a + basis (one working, one protection). OC- optical interface circuit packs are available in four reaches, each with a different system gain: Optical interface System gain (BER = 0 0) Intra-office (30 nm) Intermediate reach (30 nm) Long reach (30 nm) Extended reach (550 nm) 5 db 9 db 9 db 9. db OC- networking interface circuit packs (NT7E0xx) cannot perform virtual tributary bandwidth management (VTM). VTM capability is provided by the OC- VTM circuit pack (NT7E05xx). See Table 3- for ordering codes for OC- networking circuit packs. OC- interfaces with changeable optical connectors OC- interfaces with changeable optical connectors (NT7E0Px and NT7E0Nx) provide the same functionality as the OC- networking interfaces (linear, ring and intra-office) with fixed optical connectors (NT7E0Ex, NT7E0Fx, NT7E0Jx, NT7E0Kx, NT7E0Lx, NT7E0Mx and NT7E0XB). OC- interface circuit packs NT7E0Px and NT7E0Nx are compatible with Release 9 software, or later. Circuit packs with changeable optical connectors use a universal adapter to permit use of ferrule (FC), straight (ST) or subscriber connectors (SC). (FC connectors are steel-threaded, SC connectors are plastic snap-in, and ST connectors are bayonet press-and-twist.). Connector types can be changed easily. Circuit packs with universal adapters reduce the number of spares needed and permit easier cleaning. Order circuit packs and optical connector kits separately. The circuit packs with changeable optical connectors and their functional equivalents are as follows: NT7E0PA replaces NT7E33CA, NT7E33DA and NT7E33EA NT7E0PB replaces NT7E0FB, NT7E0FC, NT7E0FD, NT7E0LB, NT7E0LC, NT7E0LD and NT7E0XB NT7E0PC replaces NT7E0EB, NT7E0EC, NT7E0ED, NT7E0KB, NT7E0KC, and NT7E0KD NT7E0PD replaces NT7E0JB, NT7E0JC, NT7E0JD, NT7E0MB, NT7E0MC, and NT7E0MD Ordering Information Rel 4 Standard Feb 00

32 3-4 Circuit packs NT7E0NA replaces the NT7E33EA for Release, and later NT7E0NB replaces the NT7E0XB for Release, and later NT7E0GA replaces NT7E0DB, NT7E0DC and NT7E0DD NT7E0GB replaces NT7E0CB, NT7E0CC, and NT7E0CD Note : OC- circuit packs that provide ring functionality (NT7E0Ex, NT7E0Fx, NT7E0Jx, and NT7E0Px) can replace the OC- linear networking interface circuit packs (NT7E0Kx, NT7E0Lx, and NT7E0Mx) in all OC- linear applications. Note : Use OC- networking interfaces (NT7E0Px) for ADM functionality in a linear ADM, or in a NWK ring ADM (ring circuit packs only). Do not use NT7E0Px circuit packs in VTM ring ADM network elements. These network elements use NT7E05xx network interface circuit packs. Note 3: The OC- interface circuit packs (NT7E0Px) are compatible with Release 9, or later for SONET functionality. For Release 3, the NT7E0Px circuit packs can be programmed for SONET or SDH functionality. Note 4: Use circuit packs with SDH functionality only in terminal network elements. Note 5: The following interface circuit packs are manufacturer discontinued: NT7E0XB, NT7E33CA, NT7E33DA, and NT7E33EA. OC- intra-office and STS- circuit packs The OC- intra-office optical carrier circuit pack (NT7E0PA) provides the same functionality as the STS- electrical carrier circuit packs, for Release 9 software or later. The intra-office circuit pack uses fiber optic cables instead of the coaxial cables required for the STS- circuit pack. Connectors for the intra-office circuit pack are interchangeable and must be ordered separately. OC- SDH intra-office interface and OC- linear SDH IR interface circuit packs For Release 3 software or later, the OC- interface circuit packs (NT7E0Px) can be programmed for SONET or SDH functionality. For Release, the OC- SDH intra-office interface circuit pack (NT7E0NA) provides the same functionality as the STS- SONET/SDH interface circuit pack (NT7E33EA). The OC- linear SDH IR interface circuit pack (NT7E0NB) replaces the OC- IR 30 nm SONET/SDH interface circuit pack (NT7E0XB). Both the NT7E0NA and the NT7E0NB are compatible with Release 3. Use SDH circuit packs NT7E0NA and NT7E0NB for SONET/SDH midspan meets only. Although the midspan meet occurs at the OC-3 rate, the SS Bits within the H Byte that determine SDH or SONET functionality are controlled and provisioned by the OC- circuit packs. These circuit packs cannot be used in OC-48 tributary applications. S/DMS TransportNode OC-3/OC- NE TBM Vol Rel 4 Standard Feb 00

34 3-6 Circuit packs OC- VTM optical interface circuit packs The OC- VTM circuit pack can perform virtual tributary bandwidth management (VTM). VTM increases the efficiency of bandwidth use by providing the capability to assign, route, and control bandwidth in a SONET system with a granularity of VT.5 (.78 Mbit/s). Without VTM, VT.5 channels must be bulk-mapped in increments of 8. The VTM circuit pack is the primary optical interface in network elements with VTM. VTM capability is available only in OC- VTM ring configurations. The OC- VTM circuit pack cannot be used in linear configurations, nor can it be used in a ring that contains any NWK ring ADMs. (An NWK ring ADM has OC- networking interface circuit packs as the primary transport interfaces.) Order OC- VTM optical interface circuit packs with FC, ST or SC connectors. Circuit packs are available in two reaches, each with a different system gain: Optical interface System gain (BER = 0 0 ) (mid-span meet see note) Intermediate reach (30 nm) Long reach (30 nm).0 db 4.0 db Note:These worst-case parameters include allowances for connector losses, aging, equipment impairments due to implementation, and temperature degradation. These figures do not include the customer unallocated link margin. See Table 3- for ordering codes for VTM circuit packs. Note: OC- VTM optical interfaces are not direct replacements for OC- NWK units. Pay special attention to the optical link budget when ordering OC- VTM units for reconfigurations.

DS3 tributaries can be mixed with DS, STS-, and OC-3 tributaries on the same shelf. When mixing DS3 and STS- services, equip slots, 3, 5, and 7 with either DS3 mapper or STS- interface circuit packs (all combinations are supported). DS3 mappers and STS- interface circuit packs equipped in the same shelf share the protection switcher circuit pack (in slot ). Install OC-3 tributaries only in an OC- shelf. In an OC- mixed system, the DS VT mappers and DS3 STS mappers share the same slots. The quantity of DS VT mappers to be installed depends on the quantity of DS3 STS mappers being installed. In an OC-3 mixed system, install the DS3 STS mapper before the DS VT mappers. Once the DS3 STS mappers are installed, deprovision the unused DS3 ports before inserting a DS VT mapper. See Table 3-3 on page 3- for ordering codes. BNC I/O circuit packs Order three BNC I/O circuit packs (NT4K30AA) for each DS3 mapper or STS- interface circuit pack equipped. Each set of three BNC I/O circuit packs is associated with a DS3 STS mapper or STS- interface. Do not order any BNC I/O circuit packs for the protection DS3 STS mapper or protection STS- interface circuit pack. Order BNC I/O circuit packs in sets of three. The circuit packs fit into slots 38, 39, 40; 4, 43, 44; 46, 47, 48; and 50, 5, 5. In the OC- shelf, install up to BNC I/O circuit packs (the shelf can handle up to DS3 or STS- signals). In the OC-3 terminal shelf, install up to three BNC I/O circuit packs (the OC-3 signal can handle up to three DS3 or STS- signals). In the OC-3 add-drop multiplexer (ADM) shelf, install up to six BNC I/O circuit packs.

For more information, see Circuit Pack Descriptions, DS3 STS mapper circuit pack Order one DS3 STS mapper for every three DS3 signals required. Order one STS- interface circuit pack for every three STS- signals required. Since a maximum of three DS3 or STS- tributaries in an OC-3 TBM terminal shelf, at most one working DS3 STS mapper or STS- interface circuit pack is required, excluding protection. Since you can provision a maximum of DS3s or STS-s in an OC- TBM shelf, at most four DS3 STS mapper or STS- interface circuit packs, or a combination totalling four, are required, excluding protection. Order one additional DS3 STS mapper for each shelf for protection of DS3 signals. This circuit pack is equipped in slot. Order one additional STS- interface circuit pack for each shelf for protection of STS- signals. This circuit pack is equipped in slot 3. Equip the working DS3 mappers and STS- interface circuit packs in any of slots, 3, 5, and 7 for the OC- shelf and in slots, 3, or 5 for the OC-3 shelf. Note: If the shelf contains at least one NT7E08BA mapper, then it is required that the protection mapper be an NT7E08BA mapper in order to prevent loss of enhanced functionality. STS- interface circuit pack Order one STS- interface circuit pack (NT7E09AA) for every three STS- signals required. Since you can provision a maximum of three DS3 or STS- signals in an OC-3 TBM terminal shelf, at most one working DS3 STS mapper or STS- interface circuit pack is required, excluding protection. Since you can provision a maximum of DS3 or STS- signals in an OC- TBM shelf, at most four DS3 STS mapper or STS- interface circuit packs (or a combination totalling four) are required, excluding protection. Order one additional DS3 STS mapper for each shelf for protection of DS3 signals. This circuit pack is equipped in slot.
