Overview and feature/equipment selection 1-TN-16X overview

The TN-16X provides managed network elements at STM-16 line rate, with a wide range of tributary and aggregate options. It can support Rings, Hubs, and Point-to-Point configurations, with or without Regenerators.

TN-16X supports the following main features:

• 1310 nm and 1557 nm optics (LTE/Ring/Regen)

• HPTx & Optical Amplifiers (LTE/Ring/Regen)

• Earthquake hardened rack (LTE/Ring/Regen)

• STM-1e tributary (LTE/Ring only)

• Dual STM-1e/140 Mbit/s tributary (LTE/Ring only)

• STM-4 optical tributary (LTE/Ring only)

• STM-16e intershelf (LTE only)

• Order Wire (LTE/Regen only)

• STM-1 optical (1+1 protected) tributary (LTE/Ring only)

• 3 x 34 Mbit/s mapper tributary (LTE/Ring only)

Typical applications demonstrating the features listed above are described in Chapter 2.

The TN-16X product range comprises two types of subrack:

• TN-16X LTE/ADM/Ring subrack which can be equipped with core, aggregate and tributary units to be used as a Line Terminal (LTE), Add-Drop Multiplexer (ADM) or Ring.

• TN-16X Regenerator subrack which can be equipped with core and aggregate units to be used as a Regenerator. The Regenerator subrack can also be used as an ‘overflow’ subrack for an LTE/ADM/Ring to provide additional slots.

The equipment is packaged as fully equipped racks. A 2.2 m high TN-16X rack can contain:

• Three Regenerator subracks or

• Two LTE/ADM/Ring subracks or


1-2

Overview and feature/equipment selection

• One LTE/ADM/Ring subrack and one Regenerator subrack

Overhead cabling is catered for as standard. Under-floor cabling can be accommodated by using the earthquake-hardened rack and rack fibre channel.

An LTE/ADM/Ring subrack has four quadrants, each having four tributary slots. Tributary units can be of single- or double-width. Only tributaries of the same STM level can occupy a quadrant.

The TN-16X can accommodate 2 Mbit/s tributaries by connecting the required number of TN-1Xs, TN-1Ps, or TN-1Cs via the TN-16X STM-1 electrical tributary units.

Table 1-1 gives an overview of the TN-16X tributaries available. See the section starting on page 3-13 for full details of the tributary slot equipping rules.

STM-16 optical aggregates are available at 1557 nm and 1310 nm with a choice of optical connector (FC/PC or SC). High Performance Transmitters (HPTx) and Optical Post Amplifiers (OPA) are also available.

STM-16 electrical intershelf transmitters and receivers are also available for LTE applications.

Transmitters and receivers are WDM-ready. Different transmitters are used for the basic wavelengths of 1310 nm and 1557 nm (and at future releases the associated WDM wavelengths of 1533 nm, 1541 nm, and 1549 nm). The receivers operate at all of the wavelengths listed above.

Table 1-2 gives an overview of the aggregate options available.

Standardised network and maintenance management is provided via a workstation or craft terminal. Network Management communications is controlled via the Operations Controller (OPC) which is a Hewlett-Packard UNIX workstation re-packaged as a plug-in unit. In a medium sized network, typically two OPCs will be provided (one master, and one backup). The OPC can administer a maximum of 34 NE subracks (consisting of ADMs, Terminals or Regenerators).

The Network Manager (TN-MS NRM) is implemented on an HP 9000 715/100 platform. One Network Manager can control 20 Element Controllers (OPC or OPC pair), or 1280 Network Elements (whichever limit is reached first).

Applications and features 2-Applications

This section identifies typical TN-16X applications as an aid to the features selection process described in Chapter 1. It indicates the unit combinations required (as a minimum) to implement each multiplexer configuration. Examples of typical subrack equipping are also provided.

This section deals with the following:

• Ring multiplexers

• Regenerators

• Line Terminal multiplexers

• Add/Drop multiplexers

• Hub multiplexers

• High Performance Transmission multiplexers

Ring multiplexersSelf-healing, Multiplex Section Shared Protection Rings (MS SPRings), see Figure 2-1, are available at this release. The multiplexer uses two fibres to provide two-way protection capacity shared by all nodes on the ring. Each node supports tributary traffic up to the equivalent of the STM-16 bandwidth. STM-8 of the capacity, fully protected, is available for working traffic between any two adjacent nodes. In the event of a fibre cut or failure anywhere along the ring, all restorable traffic will be automatically re-routed within a pre-defined time period.

Shared protectionUp to a maximum of sixteen nodes are possible in a shared Protection Ring (this maximum is set by the Automatic Protection Switching protocol using overhead K1 and K2 bytes which has four bits allocated for ring node identifier). Regenerators are not counted as nodes and hence are additional to the maximum number of sixteen. The maximum number of Regenerators between Ring Nodes is the same as Terminal multiplexer applications, i.e. thirty.

Each Regenerator can accommodate four complete sets of optical interfaces (two sets for each transmission direction). A single subrack can support point-to-point applications employing either 1:1 or 1:N revertive protection. In route diversity applications only one set of optical interfaces are required in each Regenerator subrack.

Note: Different numbers of Regenerators may be deployed in the working and protection channels according to path length.

A Regenerator subrack can regenerate up to two optical channels, thus for a 1:3 protected terminal multiplexer system, two Regenerator subracks would be required at each Regenerator site.

The Regenerator subrack may be used to house High Performance Transmitter (HPTx) or Optical Post Amplifier (OPA) in an ‘overflow’ situation where, due to the configuration required, no space is available in the LTE/ADM/Ring subrack. The total number of HPTx or OPA units is constrained by the number of slots available in the backplane, as well as thermal limitations.

Terminal multiplexers The following types of terminal multiplexer applications are described in this section:

• Protected terminal multiplexers:

— Protected terminal via 2-node shared protection ring.

— 1:N protected terminal multiplexer.

• Unprotected terminal multiplexer. This is a 1:N protected terminal where n=0 (see Figure 2-2).

Figure 2-2Unprotected terminal

When configured as a point-to-point terminal (LTE), the TN-16X can support various combinations of 34 Mbit/s, 140 Mbit/s, STM-1e, STM-1o and STM-4 tributary/inter-shelf interfaces up to the full STM-16 bandwidth. 2 Mbit/s tributaries are supported through the use of STM-1e connections to TN-1Xs.

Internally, the STM-16 Terminal subrack bandwidth is divided into four STM-4 ‘Quadrants’. 34 Mbit/s tributaries are only allowed in Quadrant 4. Quadrants may only be shared with tributaries or tributary/inter-shelf interfaces of like bandwidth.

Protected terminal multiplexersProtection at the STM-16 interface is available using the following schemes:

• Protected terminal via 2-node shared protection ring, see (i) below and Figure 2-3.

• Multi-shelf 1:N: The optical interfaces are protected in a revertive scheme which consists of one protection channel for up to fourteen working channels, see (ii) below and Figure 2-3. Refer to Nortel for the availability of n>2.

All configurations automatically switch traffic to a standby path in the event of signal failure/degradation or optical interface failure in the working path. Revertive protection subsequently switches traffic back to the original working path if a fault-free state exists for longer than a pre-defined interval.

(i) Protected terminal via 2-node shared protection ringA point-to-point STM-16 link can be protected via a two-fibre shared protection ring, see Figure 2-3. This provides quasi 1 +1 protection.

Figure 2-3|Protected terminal via 2-node shared protection ring

Note: This configuration can be used with or without Regenerators

(ii) 1:N protected terminal multiplexerMulti-shelf 1:N (where n = 1 to 2) revertive configurations allow several TN-16X subracks to share a single protected channel, see Figure 2-3. The protection channel can be used to carry additional, low priority traffic while protection switching is in the normal inactive state. With protection enabled, low priority traffic is discarded and high priority traffic from the failed channel is routed to the protection channel.

Note 1: Each node requires 1:N electrical Tx and Rx protection units for the STM-16 protection loop.

Note 2: The local protection path is an electrical STM-16 interface provided by a PLoop transmitter. For working channels this local loop is mounted in ‘G2’ with the working channel optics in ‘G1’. For the protection channel the local loop mounts in ‘G1’with the corresponding receiver in ‘G2’. The protection channel optical receiver mounts in ‘G1’, with the transmitter in ‘G2’.

Unprotected terminal multiplexerAn unprotected terminal multiplexer, see Figure 2-5, provides a point-to-point link with a single STM-16 optical link.

As a basic requirement, a single unprotected terminal multiplexer (with only one line interface) will be equipped with the following unit combinations:

• one optical aggregate interface set.

• Up to sixteen 140 Mbit/s or STM-1 electrical tributaries.

2 Mbit/s tributaries are supported through the use of STM-1e connections to TN-1Xs, see Figure 2-5.

This configuration can be used with or without Regenerators (see page 2-2).

Hub configurationHubs with STM-1 and STM-4 optical aggregates are available at this release.

Simple optical hubs can be deployed to consolidate several spur routes onto high capacity STM-16 optical fibre. These arrangements eliminate the cost and complexity of multi-terminal configurations and redundant cross-connections. The STM-16 terminal subrack supports up to sixteen STM-1 spur route interfaces. Mixed arrangements of optical/electrical interfaces can also be provided in hub applications.

This configuration supports up to sixteen spur route interfaces. The TN-1X performs the tail-end switch (not carried out by the TN-16X).

Figure 2-6 shows an example of a TN-16X hub application.

Figure 2-6Hub configuration example

High Performance TransmittersThe standard optical transmitter can be replaced by a High Performance Transmitter (HPTx) to achieve operation over extended distances with standard fibre, or a Optical Post Amplifier (OPA) to achieve operation over extended distances with dispersion shifted fibre.

Up to two HPTxs can be equipped in a multiplexer subrack, in the slots normally reserved for Order Wire and OPC. If the subrack already contains an

OPC, then the OPC can be housed in a co-located Regenerator subrack and linked to the main subrack by a CNET connection. In the Regenerator subrack the HPTx or OPA can be located in any of the transmitter or receiver slots (subject to thermal limitations).

In addition, the HPTx requires an electrical input provided by an electrical transmitter, whose type depends upon the application, e.g. Ring, Linear or Regenerator. This electrical transmitter physically replaces the standard optical transmitter. The OPA derives its input directly from the standard optical transmitter.

In 1:N protected configurations, both the working and protection channels can be equipped with the longer reach HPTx and OPA.

Core equipment 3-Rack equipment
Selection of rack equipmentTN-16X equipment is supplied in equipped Nortel ETSI 2.2 m high racks. The type of rack supplied is dependent on the application.

The TN-16X racks are fully equipped with all necessary equipment to support the allowed number of subracks, although certain items can be ordered separately.

The LTE/ADM/Ring rack can support two LTE/ADM/Ring subracks. The Regenerator rack can support three Regenerator subracks.

A Rack Fibre Channel kit NTFW52AA, that fixes to the side of the rack is necessary for certain applications:

• Required for LTE/ADM/Ring applications requiring a greater than half-fill of STM-1 optical tributaries.

• Required for LTE/ADM/Ring and Regenerator applications where under-floor cabling is used.

• The Rack Fibre Channel can only be used with the earthquake hardened racks.

The TN-16X racks and ancillary equipment are listed in Table 3-1.

Typical rack layouts are shown in the Figure 3-1 to Figure 3-4.

Tributary units 5-Selection of tributary units

STM-1, 140 Mbit/s and 34MBit/s electrical, STM-1 optical, and STM-4 optical tributaries are available for TN-16X LTE/ADM/Ring applications.

The range of tributary units available is listed in Table 5-1. The individual units are described briefly starting on page 5-4.

Each quadrant can only be equipped with tributaries of like bandwidth; once a tributary unit is positioned in a quadrant, that defines the quadrant use. For example, STM-4 tributaries cannot be mixed with STM-1 tributaries in the same quadrant.

Each electrical tributary unit must have a corresponding I/O unit which provides the electrical input/output. Optical tributaries do not require I/O units.

STM1o IR 1310 Tributary (SC) NTFW11BDThis unit is an STM-1 optical 1310 nm short haul tributary. It is a half height unit; one or two units can be housed in a single active carrier. One unit is required for unprotected operation, and two units fr 1+1 protection. It is fitted with SC connectors. To use the unit in an installation where FC/PC connectors are employed, use Optical Adaptor SC-FC (PC) A0644519.


• An STM-1 optical tributary cannot be mixed in quadrants containing STM-4 optical tributaries.

• Requires no active I/O.

• If a greater than half-fill of these units is required in a rack, then the earthquake-hardened rack and rack fibre channel must be specified (see Chapter 3); high speed fans must also be specified.

• Codes required:

— STM1 Optic Carrier assy NTFW19AA (page 5-6)

— For rack with greater than 50% fill of optical tributaries:

– STM16 Earthquake Rack Assembly NTFW70AB page 3-8 with Fibre Channel NTFW52AA and Fan assembly 4 x NTFW55BA.

— Optical Adaptor SC-FC (PC) A0644519 (optional, for use with FC/PC cables)



Note: The serial number on the STM-1o circuit pack consists of a 4 digit manufacturing source code followed by a 5 digit identification code.

STM1 Optic Carrier assy NTFW19AAThis is an active carrier which houses one or two STM-1 optical tributary units.


• Can be fitted to slot positions:2 to 5 and 12 to 1521 to 24 and 36 to 39.

Support equipment 6-Selection of support equipment

External synchronisation and Order Wire units are available for the TN-16X.

The units available are listed in Table 6-1 and individual units are briefly described starting on page 6-4.

External synchronisationExternal synchronisation units are available to provide synchronisation for TN-16X subracks at 1.544 Mbit/s and 2 MHz. At least one ESI is required at every LTE/Ring/ADM or Hub subrack and is not required for Regenerators.

A 120 Ω or 75 Ω ESI Clock Conversion kit (Telecoms Solutions DCD-521) is required at each NE using the 1.544MBit/s ESI to receive an external timing reference. The ESI Clock Conversion kit is rack-mounted in a separate ETSI rack from the TN-16X rack.

Order WireOptional Order Wire equipment provides maintenance personnel with a number of audio interfaces between LTE subracks and Regenerators.

Support equipment dataExternal synchronisation interface (1.544 Mbit/s) NT7E27BA

The External Synchronisation Interface (ESI) allows the shelf timing to be improved either through the use of the on-board Stratum-3 clock, or by synchronising the shelf timing to an SSU via a 1.5 Mbit/s input.

The ESI can also function as a timing reference for external equipment by generating a SSU compatible 1.5 Mbit/s timing. The ESI Unit output can be locked to an incoming STM-n signal, or to the equipment clock.

The ESI Unit is ‘half-height’ and one or two may be mounted in a single ESI Carrier. Two ESI units operate as a main and standby pair.


• Rings and Linear systems require a minimum of one ESI unit per ADM or LTE, or optionally two ESI units where protected synchronisation is required.

• 1.5 Mbit/s and 2 MHz ESI units can coexist in a network.

• For European working an ESI Clock Converter Unit is required. A choice of 120 Ohm or 75 Ohm terminations is available (page 6-3). 75 Ohm working also requires Termination NTFW5072.

• Requires an ‘External synchronisation interface carrier NT7E19AA’ (page 6-3). One is required per two ESI Units, fitted in slot 40 of the subrack,

• For ESI cable codes, refer to page 6-5.

• See Table 2-6 for details of power dissipation, weight, and unit width.

External synchronisation interface (2 MHz) NTFW27AAThe External Synchronisation Interface (ESI) allows the shelf timing to be improved either through the use of the on-board Stratum-3 clock, or by synchronising the shelf timing to an SSU via a 2 MHz input.

The ESI can also function as a timing reference for external equipment by generating a SSU compatible 2 MHz timing. The ESI Unit output can be locked to an incoming STM-n signal, or to the equipment clock.

Cables for HPTx and 1:N protectionOnly a 10 metre cable (patch cord) should be used between the HPTx and its associated electrical transmitter. The type of cable tail employed is different for LTE/ADM/Ring and Regenerator subracks, and whether the cable is connected to an HPTx or electrical transmitter (see Figures 6-1 and 6-2).

The cables (patch cords) joining the electrical transmitters and receivers of the 1:N protection loop should use cable lengths from 10 to 30 metres (see Figure 6-3).
