Product Technology

This chapter presents the general system technology and the available protection architectures for Cisco’s dense wavelength division m ultiple xin g (D WDM) m etro sy st em, the Cisc o ONS 152 00.

1.1 Optical System Description

The ONS 15200 DWDM metro system transports da ta over wavel engths using fiber-optic cables. The ONS 15200 operates in the 1550 nm transm ission win dow. Over a single optical fiber pai r, the ONS 15200 can carry up to sixtee n channe ls of data in the follo wing bit ra tes and for mats:

• 155 Mbps – SONET OC-3 or SDH STM-1

• 622 Mbps – SONET OC-12 or SDH STM-4

• 2.5 Gbps – SONET OC-48 or SDH STM-16

• 100 Mbps – 1. 25 Gbps, pass-thro ugh mode /2R operat ion

CHAPTER

Protected or unpro tec ted da ta can tra nsmi t ov er the ON S 1 520 0. The optical layer is independent of the electronic protocol that is external to the ONS 15200 system. You

can use any hig her-level p roto co l, inc lud in g pro pri et ary p rod uc ts, wit hin the ON S 1 5200 sy stem . Any protocol used must fulfill the requirements listed in this book, including the bit rates listed in this section.

1.2 Optical Channels

In the ONS 15200 system, optical channels transport informatio n between two client-layer interface ports. All optical channels in the ONS 15200 system are duplex channels, which means that traffic flows in both directions. The optical channels can be unprotected, as described in the “Unprotected Channels”

section on page 1-1 , or pro tected , as descr ibed in the “Pro tected Ch ann els” section on page 1-2.

1.2.1 Unprotected Channels

In an unprotected channel, protection fiber is not available. Only one fiber sends traffic to the client layer of the receivin g no de . You can use unprotecte d chann el s wher e pro tec tio n is n ot ne ede d or if th e cli ent layer provides pro t ect ion.

2.1 ONS 15200 Network Configurations

The ONS 15200 operates in several network configuration arrangements. All ONS 15200 configurations consist of one or more ONS 15252 Mult ichannel Un its (MCU) or ONS 15201 Single -Channe l Units (SCUs). The following inf ormation describe s some standar d ONS 15200 network configura tions, including:

• The “Bus Confi guration ” sect ion on page 2-1

• The “Ring Conf igurati on” section on page 2-2

• The “Dual-Home Configuration” section o n pag e 2-3

• The “Multichannel Point-to-Point Configuration” section on page 2-3

CHAPTER

• The “Ring Configuration with Hubbed and Meshed Traffic” section on page 2-4

• The “Full-Mesh Configuration” section on page 2-5

2.1.1 Bus Configuration

In an ONS 15200 system bus configu ratio n, waveleng th channe ls link an ONS 152 52 MCU to ONS 15201 SCUs. Use this confi guratio n only in networks where opti cal-la yer fibe r protec tion is unnecessary. It is possible to configure the bus configuration for layer-3 load-sharing protection or client layer 1+1 APS, but the two data traffic flows would need to share the same optical fiber path, and therefore protecti on would be incomple te.

In the bus configuration, the Client Layer Interface Port (CLIP) modules located in the ONS 15252 MCU and in each ONS 15 201 SCU excha nge data. Figure 2 -1 illustrate s the ONS 15200 syste m bus configuration.

Note The physical connec tion in Figure 2-1 consists of two fiber-optic cables.

2.1.3 Dual-Home Configuration

In the dual-home configuration, a pair of ONS 15201 SCUs share the total data traffic load between two different fiber-optic cable (fib er) rou tes. The pai r of ONS 15201 SCUs can use id entic al or different wavelength channel s to comm unicate with thei r respec tive ON S 15252 MC Us. Usin g ident ical wavelength channels conserve s network resource s. In addit ion to load sha ring, the dual-hom e configuration pro vide s tr affic pro tec tio n in the el ect ro nic cli e nt-la ye r dom ain . If one fi ber rou te is lost, the data traffic shifts to the other fiber route in the client layer.

In addition to protecting traffic at the client layer, the dual-home configuration protects the ONS 15200 system against single MCU or SCU failures. Figure 2-3 illustrates the ONS 15200 dual-home configuration.

Note The physical connec tion in Figure 2-3 consists of two fiber-optic cables.

2.1.4 Multichannel Point-to-Point Configuration

In the ONS 15200 multichannel, point-to-point configuration, multiple wavelength channels exist between a pair of ONS 15252 MCUs. You can set up the multichan nel point- to-point configur ation wit h or without optic al-l ay er pro tec ti on. Co nfi g uring op tica l-l ay er prot ect ion r eq uire s d ual fibe r ro utes.

In the ONS 15200 multichannel, point-to-point configurations, dual fiber routes send information along two separate fiber routes . The dual physical rou te configu ration suppo rts SONET or SD H add/drop multiplexer (ADM) prote ction and c lient-la yer 1+1 APS prot ection.

Cisco does not r ecom mend impl eme nti ng layer-3 l o ad-sha ring p rote ction i n a mu ltic ha nnel point-to-point confi guration because the two netwo rk fiber rout es need to share an ONS 15252 MCU, and any failure of the ONS 15252 MCU would cause both routes to disappear simultaneously . Figure 2-4 illustrates the ONS 15200 multichannel, point-to-point configurations.

2.1.5 Ring Configuration with Hubbed and Meshed Traffic

In the ONS 1520 0 r ing co nfig urat ion with hub be d and m esh ed tra ffic, t wo O NS 1 520 1 SC Us communicate with each other. You can use either unit in a direct point-to-point configuration throu gh a control area network (CAN) bus connection as shown in Figure 2-5, or with a noninterfering ONS 15252 MCU. If you u se an O N S 1 5252 MCU , the MCU m ust ha ve a n in st alled Br idge m odu le (BM) .

To manage a mesh configuration, use the Maintenance Manager (MM) software and associated hardware or use a CAN bus extension cable to connect one of the ONS 15201 SCUs using the meshed channel to the ONS 15252 MCU. An ONS 15201 SCU connected in this way will be on the same logical CAN bus as the ONS 1 525 2 MC U.

3.1 Modularity and Ancillary Equipment

Equipment in the ONS 15200 syst em is modula r in design. Ea ch system function i s carried out by modules located in eit her an ONS 152 52 MCU or an O NS 1 5201 SCU . Sites i n the ON S 15200 system consist of eit her an ON S 15 252 M CU, a n ON S 1 520 1 SC U, or a co mb inat ion of the two. ON S 1520 0 site configurations may al so include a power dis tribution pa nel (PDP) .

3.1.1 ONS 15252 MCU

CHAPTER

The ONS 15252 MCU com mu nica tes w ith t he ot her nod es in t he O NS 15 200 syst em on one or seve ra l channels. Each c ha nnel o ccup ies a wav ele ngth, a nd some O NS 15 200 sy stem c onfi gur atio ns reuse a wavelength. As shown i n Figure 3-1, several channe ls of info rmati on, eac h occup ying a wa veleng th, enter the node from the DWDM layer. Each channel can enter the ONS 15252 MCU fro m the A side, the B side, or the A side and B side.

The ONS 15252 M CU c om mun icat es w ith the oth er n ode s in the ON S 1 520 0 syst em on o ne or mor e wavelengths. Information originates at the ONS 15252 MCU Client Layer Interface Port (CLIP) module. For optically-protected channels, the Network Adaptation module (NAM) splits the information and transmits it in opposite directions through two Hub Filter Modules (HFMs) and two Line Modules (LMs) at a specific wav elengt h.

For unprotected channels, the N AM transmits the in formation to eith er an A-side H FM or a B-side HFM and then thr ough t h e associ at ed L M. I nf orm ati on car rie d o n a wa vel engt h int end ed f or a nothe r O NS 15200 site passes through the ONS 15252 MCU without interference except for the insertion loss of the ONS 15252 MCU, if a BM or a CMX is used. If the ONS 15252 M CU is equipped wit h Termination modules (TMs) inst ead of a B M, t he T Ms b lo ck a ny wav elengt h or c hanne l n ot d rop ped t o t he ONS 15252 MCU.

Two versions of the ONS 15252 M CU mec hani cal she lf exi st: Rel eas e 1.0 a nd Relea se 1.0. 1. Cisc o currently ships only the Relea se 1.0.1 shel f and no longe r ships the Rel ease 1.0 shelf.

Release 1.0.1 and later shelve s inc l udes a baffle. The baffle is a partial ly- p er fo r ated , ang led metal plate that is mounted below and behind the metal support beam and is mechanically attached to the back of the shelf. It runs the width of the shelf. To view the baffle, look up through the ventilation cavities at the back of the shelf. Fi gure 3-2 illustrates a shelf with a baf ffe (Release 1.0.1), and a shelf without a baffle (Release 1.0).

ONS 15252 Releases 1.0.1 and lat er include a fa n unit. Befor e using the Rele ase 1.0.1 shelf, you must install the fan unit. Do not use the fan unit with a Release 1.0 shelf. See the “Fan Unit” section on

page 3-4 for more in format ion about the fan unit .

Caution You must install the fan unit in a Release 1.0.1 shelf. Running the Release 1.0.1 shelf without the fan

unit will result in a unit that is not compliant to any specifications, nor is warranted or supported by Cisco. In addition, such usage ma y result in eq uipmen t damage .

Caution Do not install the fan unit in a Release 1.0 shelf. Running the Release 1.0 shelf with a fan unit will

result in a unit that is not compliant to any specifications, nor is warranted or supported by Cisco. In addition, such usage may resu lt in equi pment dama ge.

ONS 15252 Releases 1.0.1and l ater inclu de an updat ed Netwo rk Adaptati on modu le (NAM). Th e Release 1.0.1 NA M ha s a “NEBS-3 compliant” label on the faceplate, whereas the previous version of the NAM does not have a faceplate label. The Release 1.0.1 shelf requires the Release 1.0.1 NAM. You can also use Release 1.0.1 NAMs in the Release 1.0 shelf. See the Cisco ONS 15200 Module Handbook for more informati on about t he NAM.

Caution Placing NAMs without the “NEBS-3 compliant” label into an Release 1.0.1 shelf may result in

equipment damage .

3.1.2 ONS 15201 SCU

The ONS 15201 SCU communicates with the othe r nodes in the ONS 152 00 system on a spe cific wavelength or channel. T he SCU use s a single CLIP mo dule . From th e DWD M lay er, several chan nels of information, eac h occup ying a wav elength , enter t he ONS 15201 SCU. Each D WDM cha nnel of information can enter the ONS 152 01 SCU from the A side, the B side, or the A side and B side .

The Collector Filter module (CFM) drops and transfers the specific channel or wavelength intended for the ONS 15201 SCU to the CLIP module. For protected channels, the CFM drops the chann el from the A side and B side. For unprotected channels, the CFM drops the channel from either the A side or B side.

The CLIP transfers information originating at the ONS 15201 to the CFM for protected channels. The CFM splits the information and transmits it at a specific wavele ngth or channel in op posite direction s on the A side and B side. The CFM does not split unprotected channels; it transmi ts the m directly to ei ther the A side or B side. Information carried on a wave length or channel inte nded for ano ther ONS 15200 node passes through the ONS 15201 SCU without inte rferenc e except for the insert ion loss cause d by the unit. Figure 3-3 shows a functional repr esenta tion of an ONS 15201 SCU.

Network Management Overview

An internal da ta bus, a lso ca lled a c ontr ol ler are a ne two rk (CAN ) bu s, co nnec ts an N C B m odule to different CLIP modules of the ONS 15252 MCU. You can extend this data bus over several co-located network elements (ONS 1525 2 MCUs or ONS 152 01 SCUs) to a larger logic al unit. The O NS 15 201 SCU uses the same d ata b us as t he M CU . N orm ally one CA N bus c onn ect s al l O NS 15 200 e quip ment located at one site.

An overhead cha nnel ex is ts and is imp lem en ted as a ba se b an d modu l ation on the ind i vidua l D WDM optical channels. T wo end-points of a channel communicate using this low frequency signal, called QPP (Qeyton Proprietar y Pr otoc ol). The QPP spe cifica tio n def ine s the physi cal an d lin k la yer pro toco ls f or communication .

Any CLIP module co ntrolled by an NCB mu st not be more than two QPP hops away from that NCB. If the CLIP is further away from the NCB, you must install additional NCB modules.

Release 1.1 allows you to co nfigure up to two activ e NCBs as mana gers of any CLI P in a network . To manage the CLIP, it must be no further than two CAN and two QPP hops away from the NCB. Any NCB in a network that is not provisioned as an active manager of a CLIP can still inventory the CLIP.

Two pins of the MA interface host the EIA/TIA-232 port; therefore, access the EIA/TIA-232 using the EIA/TIA-232 cable that is include d with the ON S 15252 MCU. A fter you have set the IP add ress, you can communicate with t he NCB modul e throug h the Ethern et port loc ated on the front of the NCB.

Figure 4-2 on pa ge 4-5 illustrates EIA/TIA-232 interface access and Ethernet access to the ONS 15252

MCU. After you have assi gned an I P addr es s to t he N CB mo dul e, you can also se nd inf orm atio n to the NCB

module by file transfer protocol (FTP). Set the EIA/TIA-232 interface to the parameters listed in

Table 4-1. Set the terminal settings to ASCII (send line end with line feed).

The CLI interf ace r esid es on the NCB mo dule and op er ate s o n th e data base serv er f or t he O NS 15200 system. The CLI interface has two modes of access for users—read-and-write access and read-only access. Users are separated into three categories: administrator, operator, and guest. Each category has different privileges:

• Administrator—read-and-write access to security management data

• Operator—read-and-write access to ne tw ork m an agem ent dat a

• Guest—read-only access to network ma nagement data

To access the CLI interface, use the Eth er net port on the NCB m odul e or the MA int erfa ce o n the C IM module. MA interface access requires a EIA/TIA-232 cable.

4.5 Maintenance Manager

The Maintenance Manager (MM) interactive software tool, installed on a laptop or PC, provides a local craft interface for the ONS 15200 system. The MM software provides access to the internal data bus at ONS 15252 MCUs or ONS 15201 SCUs. It also facilitates access to data from isolated ONS 15201 SCUs in the ONS 15200 network.

5.2 Client Layer Interface Port Module

The CLIP module provides the input port from the client layer to the integrated ONS 15200 system, and the output port from the integrated ONS 1520 0 to the client la ye r. The CLIP module receives an optical input signal from the client layer in either the 1310 nm or 1550 nm wavelength regions and converts the

78-13766-01

Cisco ONS 15200 Product Description

5-1

Communication Interface Module

optical signal to a specific International Telecommunication Union (ITU-T) G.692-compatible wavelength. The C LIP mo dule then transf ers the converted optical s ignal to the DW DM side of the ON S 15200 network.

When the CLIP module receives the optical signal from the DWDM side of the ONS 15200 network, the CLIP module conve rts th e se lect ed opt ica l sign al to the 1 310 nm w ave len gth re gion an d delive r s it to the client layer. If the ONS 15200 system is optically protected (that is, th e optical signal is carried on two routes), the CLIP module selects which optical signal to transfer to the client layer. You can install a CLIP module in either the ONS 15252 Multichannel Unit (MCU) or the ONS 15201 Single-Channel Unit (SCU).

When the CLIP modules are not installed, attach front covers for elec tromagnetic compatibility and electromagnetic interference (EMC/EMI) precautions.

Release 1.1 provides a new CLIP module that incorporates both clocked (3R) and unclocked (2R) data regeneration. You can set the mode of operation (2R or 3R) usin g th e m anag emen t int erf ace s. T he new 2R/3R CLIP is fully compatible with the existing 3R CLIP. The 2R/3R CLIP is user configurable for unprotected or fib er prot ecte d opera tio n.

In addition, Release 1.1 provides two dispersion tolerances: 1800 ps/nm at 0 and 7 dBm, and 3000 ps/nm at 0 dBm.

5.4 Network Adaptation Module

The NAM splits the ou tgoi ng optica l si gnal from t he CL IP m odu le (o ne of t he D WD M wa vele ngths o r channels) before tr ansfe rr ing it t o the pa ssive op tical she lf (l ocat ed in the lowe r part of the O NS 15252 MCU). The NAM split ratio can be 100/0, 90/10, 50/50, 10/90, or 0/100. Unprote cted channe ls use the split ratios 100/0 and 0/100. Protected channels use the split ratios 90/10, 50/50, and 10/90.

The NAM transfers the signal to the passive optical shelf in the following patterns:

• A side or B side (unprotected channel)

• A side and B side (protected channel)

The HFMs collect the inc oming opt ical signa ls from the DWDM side of the ONS 1520 0 system and transfer the outgoing signals t o the DWDM side of the ONS 15200 syste m. The NAMs the n transfer these incoming/outgoing optical signals to/from the CLIP modules.

5.5 Network Control Board Module

The NCB module is the hardware platform for the Subnetwork Manager (SNM) software package, which you access using t he E ther net conn ect or on t he f ron t of the NC B m odu le. T he N CB super vis es, administers, and monitors the ONS 15200. In addition to controlling all of the ONS 15200 system CLIP modules, the NCB module collects information about system status, alarms, parameters, and actions on the internal data bus. You can also store performance monito ring data on the NCB an d upload the da ta to external media.

Network Adaptation Module

Release 1.1 supports multiple NCBs on the CAN bus; ho wever , y ou can only configure two active NCBs as managers of any CLIP in a networ k. Any NCB in a netw ork that is no t provisione d as an act ive manager of a CLIP can still inventory the CLIP. Release 1.0.1 only supports one NCB on the CAN bus.

In addition to alarm lines on the internal data bus, the NCB has three dedicated LEDs. When lit, the LEDs indicate the status shown in Table 5-2.

Table 5-2 NCB Indicators

LED Status

Red Critical or major alarm Amber Minor alarm or wa rnin g Green Pow er on

The ONS 15200 system can function without the NCB module. Whe n you choose not to use an NCB module, mount a front cover in its place for EMC/EMI precautions. The front cover used in place of the NCB module is narrower than the front cover used in place of the CLIP module. Do not interchange the two types of front co ve rs.

Bridge Module

5.6 Bridge Module

The BM, installed in the passive optical shelf, transfers the remainder of the incoming optical signal from the A side to the B side and from the B side to the A side. The BM allows the por tion of the optic al signal that is not intended for the node to bypass the node. If all incoming optical signal wavelengths terminate at the node, you can us e two Termination modules (TMs) instead of a BM. TMs reduce optic al crosstalk.

5.7 Collector Filter Module

The CFM combines the functionality of the Hub Filter module (HFM) and the NAM in the ONS 15201 SCU. The CFM transfers optical signals between the DWDM side of the ONS 15200 system and the CLIP module.

5.8 Connection Module X

Chapter 5 Module Descriptions

The CMX provides a bridge between the A side of one ONS 15252 MCU and the B side of another ONS 15252 MCU. Using a CMX allows you to extend the bandwidth capability of the ONS 15252 MCU passive optical shelf.

5.9 Connection Module Y

The CMY provides a bridge between the A side of one ONS 15252 MCU and the A side of another ONS 15252 MCU. Alternatively, the CMY provides a bridge between the B side of one ONS 15252 MCU and the B side of another ONS 15252 MCU. The CMY allows you to extend the bandwidth capability of the passive optical shelf.

5.10 Dummy Filter Module

The Dummy Filter module (DFM) mechanically stabilizes the optical filter modules. The DFM resides in the passive op tica l she lf of the ON S 15 252 MC U.

5.11 Dummy Network Adaptation Module

The DNAM replace s a Network A daptat ion modul e (NAM) when a NAM is not insta lled.

5.12 Hub Filter Module

The HFM filters one wavelength from the incoming DWDM optical signal and transfers the remainder of the waveleng ths t o sub s eque nt H FM s. Th e HF Ms e ach ad d o ne wa veleng t h to t he o ut going DW DM optical signal. The HFM is located to the right of the Line module (LM) on the A side of the ONS 15252 MCU and to the left of the LM on t h e B side of the ONS 15252 MCU. The row of HFMs must end with either a BM, a TM, a CMX, or a CMY.

5.13 Line Module

The LM receives an incoming aggregate optical signal from the DWDM side of the ONS 15200 system and transfers the outgoing aggregate optical signal to the DWDM side of the ONS 15200 system. A pair of LMs, one for the A side and one for B side, reside in the passive optical shelf of the ONS 15252 MCU. The LM contains the monitoring ports for both the incoming and outgoing traffic streams. The split ratio of the monitoring ports is 10/90. The external interface on the LM can be either an SC or an FC optical connector.

Hub Filter Module

5.14 Termination Module

Install a TM in the passive optical shelf of the ONS 1 5 252 MCU af ter the you have installed the HFMs. Insert the TM to the right of the HFMs on the A -side of ONS 152 52 MCU and t o the left of the HFMs on the B-side of the ONS 15252 MCU in plac e of the BM . The TMs term inate th e optical signal and improve crosstalk. The TMs can replace the BM when all traffic terminates at the ONS 15252 MCU.
