TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-18 UPSR Ring Operation Figure 3-19 shows a typical TE-2020 shelf for an OC-192 UPSR. This architecture will take advantage of the TE-2020 capability to transmit and receive identical high-speed data in both directions. When configured as a UPSR node, the incoming signal is duplicated, and then transmitted around both ring directions.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications applications. Figure 3-19 Two-Fiber UPSR Ring Node 3.4.1 UPSR Architecture The TE-2020 system configured as a UPSR node is capable of transmitting and receiving high-speed data in two directions. When configured as a UPSR node, the TE-2020 supports up to a single full-duplex OC192 signal. This signal is duplicated and then transmitted and received in both ring directions.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications 1) Tributary signals are bridged and transmitted through both the east and west optical PLMs at the STS path-originating node. 2) Along the route, the signals are passed through UPSR nodes located between the origination and termination point of the STS path. 3) Both copies are received at the far-end STS path-terminating node. 4) The far-end node selects the better signal as the active channel.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-22 TE-2020 OC-48 Dual Ring Interconnect Operation Unprotected UPSR Unprotected UPSR operation consists of connection based user provisioning to deselect the inherent protection path offered by UPSR configurations.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-23 Unprotected UPSR Operation Example In this example, two STS-3c-7v GbE interfaces are provisioned at Node A and Node D. The first GbE PLM traffic is connected through Node E to Node D and the user has selected “Unprotected” connections. The same is done for the GbE PLM 2 but it is directed through Node B and Node C to reach Node D, therefore only 21 circuits are provisioned on each direction of traffic.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Table 3-9 Linear ADM vs. 2-Fiber UPSR Architecture Feature Linear ADM UPSR Transmission Characteristics Working and protect channels carry data to far-end and bring data from far-end. High speed facility switches in the event of fiber failure. Both channels transmit and receive to/from both ring directions. Path terminating facility makes the signal selection.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Turin Networks BLSR rings also offer Protection Channel Access (PCA) and Non-preemptable Unprotected Traffic (NUT) provisioning features. PCA supports "extra" traffic in the BLSR protection channel, which is not protected in the event of a fiber cut or ring switch. NUT supports bidirectionally provisioned traffic in protection pairs that is not preempted by protection switching.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-25 Three Node, 2-Fiber BLSR Operation The SONET K1 and K2 bytes carry the information that governs BLSR protection switches. Each BLSR node monitors the K bytes to determine when to switch the SONET signal to an alternate physical path. The K bytes communicate failure conditions and actions taken between nodes in the ring.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-26 Three Node, 2-Fiber BLSR Traffic Pattern Following Line Break All circuits originating on Node 1 carried to Node 2 on Fiber 1 are switched to the protect bandwidth of Fiber 2. For example, a circuit carried on STS-1 on Fiber 1 is switched to STS-97 on Fiber 2. A circuit carried on STS-2 on Fiber 1 is switched to STS-98 on Fiber 2. Fiber 2 carries the circuit to Node 2 (the original routing destination).
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications NUT is Non-Preemptable Unprotected Traffic. NUT requires the user to configure a given pair of timeslots around the ring as NUT time slots. This pair corresponds to a working/protect BLSR time slot pair like 1 and 25 for an OC-48 ring or 10 and 106 for an OC-192 ring. Once the timeslot pair is configured as NUT any connections made over those time slots operate as NUT connections.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-27 Traffic Flow through a BLSR Node 3.7.1 TE-2020 Ring Fibering Scheme Figure 3-28 and Figure 3-29 show the fiber connection scheme Turin Networks suggests for the TE-2020 system for ring configurations. The ring fibers traverse the nodes on an “In on 1, Out on 2” and “In on 2, Out on 1” type scheme for each optical pair.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications 3.8 General Ring Configuration Examples and Requirements The following sections describes several typical configurations of the TE-2020 deployed in various ring applications.

Many end users favor Ethernet private line services because they allow them to connect data networks using familiar, inexpensive, data-friendly Ethernet interfaces.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications This solution features similar benefits to the GbE private line solution: a cost-effective way to deliver Ethernet-based services and traditional circuit services at an end user location, plus the survivability, manageability, interoperability, and reliability that SONET transport affords.

It is not the same as using a single STS-3c (H4 SONET overhead byte is different). A user may choose this option if the initial signal is a single STS-3c but in the future may grow to multiple STS-3cs. The VC group could then be modified.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-51 illustrates the VC mapping for an STS-3c-7v GbE connaction. Each of the STS paths in an STS-Nc-Xv connection carries its own Path OverHead (POH). This allows the SONET network to treat these paths just as it treats other STS-3c or STS-1paths. For example, the STS paths in an STS-3c-7v connection: • May occupy non-contiguous time slots, although each STS-3c time slot must fall on standard STS-3c boundaries (e.g.

The most common applications involve transparent DCC or K1/K2 transport from lower-rate OC-n signals to an OC-192 interface. Refer to Figure 3-59.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-59 Transparent DCCs passing through two TE-2020 Main Shelves 3.13.1 DCC Applications The DCC bytes in the SONET overhead are the physical layer mechanism used to deliver packets from NE to NE. Within each SONET frame, there exist three DCC bytes in the section overhead and nine DCC bytes in the line overhead. The TE-2020 has the option of using either the section or line DCC bytes for NE to NE transport.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 3: System Applications Figure 3-60 SONET Section and Line Overhead for STS-1 The DCCs used for inter-NE management through the PLMs are user configurable for either section or line. Furthermore, bonded DCC or traditional DCC can be selected. Bonded DCC is the process of combining multiple STS-1's DCC bytes into a contiguous stream of management traffic. Traditional DCC uses only the first STS-1 of an STS-N.

Chapter 4 Equipment Protection 4.1 Introduction This section describes the equipment level protection provided in the TE-2020 architecture. There are several levels of protection when it comes to the signal flow through a node. Each card type has a redundant card capable of handling traffic in the event of a failure from the first card. Also described is the inherent protection in the LEI (Local Equipment Interconnect) cabling scheme. 4.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 4: Equipment Protection There can be 1 LEI (2 cables), 2 LEI (4 cables), 3 LEI (6 cables), or 4 LEI (8 cables) connected to a single OTS2 shelf. With eight cables connected to a single OTS2 the shelf yields a full 192 STS-1 worth of bandwidth. Removal of one of the cables will not impact the connectivity between the shelves due to internal cross traffic “platforms” or “paths” designed into the LEI architecture.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 4: Equipment Protection The CCTs require redundant -48Vdc nominal power inputs within a tolerance of -42.5Vdc to -56.5Vdc, to be capable of normal operation in the event that one of the power inputs fails. 4.4 DS3/EC-1 CCT Protection The DS3/EC-1 CCTs provide the interface for all administrative commands from the TE-2020 Main Shelf and traffic from the electrical interfaces to the TE-2020 Main Shelf.

Bidirectional connections utilize bandwidth in both directions while unidirectional connections utilize bandwidth only in the from/to direction. When equipping a tributary shelf with PLMs, the LEI capacity may need to be taken into consideration.

TraverseEdge 2020 Applications and Engineering Guide, Chapter 7: Optical Link Design 7.2 Optical Link Design Determining the reach, or reliable transmission distance, achievable using a given combination of optical transmitter, physical fiber span (including splices and connectors) and receiver is commonly accomplished using the process of “Optical Link Budgeting.” This section describes the various factors relating to fiber optic transmission link budgets.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 7: Optical Link Design Prmax, are used in the link budget calculations. Prmin is the lowest average optical power level at which the optical signal can be recovered with guaranteed bit error rate of 10-12. This parameter is used when calculating the maximum link distance. Prmax is the average optical power level above which the optical receiver is in ‘overload.

TraverseEdge 2020 Applications and Engineering Guide, Chapter 7: Optical Link Design For the reasons listed above, the variance between calculated and actual attenuation on a given span can be quite high. Therefore, Turin Networks recommends measuring the actual attenuation for each link if and where possible. Chromatic Dispersion (DT) Chromatic dispersion is a result of the variance in group-velocity with frequency.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 7: Optical Link Design dispersion index (ps/nm*km), Di, and attenuation index (dB/km), Ai. In most cases, fiber spans will be power (or attenuation) limited. It is recommended, however, dispersion be measured/calculated to verify it does not exceed the limit for a given transceiver. 7.3.

Chapter 8 Node Synchronization 8.1 Introduction The TE-2020 system uses a hierarchical master-slave arrangement for synchronization to the network. There are up to six (6) user selectable synchronization reference inputs from which the distributed clock (timing reference) is selected. The system can select any of the following as either the primary timing reference or the secondary timing reference.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 8: Node Synchronization Figure 8-1 DUS Generation in a Network 8.2 Timing Modes The TE-2020 system timing mode defines the reference it uses for its internal clock. The TE-2020 supports four different timing modes: • • • • External Timing (BITS) Line Timing Loop Timing Internal Timing Each timing mode is described and specified in the following paragraphs.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 8: Node Synchronization Figure 8-2 Figure 8-3 BITS Terminations Synchronization Wire-wrap Post Identification Line Timing The TE-2020 system supports line timing where a received clock signal is taken from any incoming SONET OC-n interface to serve as a synchronization source. This does not include non-optical EC-1 signals that are available in the DS3/EC1 Tributary Shelf.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 8: Node Synchronization Internal Timing Reference The internal timing reference generated by the TE-2020 system is rated at Stratum 3 quality. All clock performance characteristics are measured at the synchronous outputs (e.g. OC-n outputs) of the TE-2020. 8.2.1 Clock Modes Clock modes are different from timing modes as described above. Timing modes define what a clock is referenced to, while clock modes define a state of the clock.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 8: Node Synchronization NOTE: The derived DS1 signals must be the same format (SF or ESF) as the external timing (BITS) input. Also, the derived DS1 signals can not source timing derived from an OC-n interfaces in an optical tributary shelf or the external timing (BITS) input. 8.2.

Chapter 9 Operations Communications 9.1 Overview Although the main function of SONET is to provide transport for voice and data traffic over optical fibers, one of the great features provided by SONET is its remote manageability. In a typical SONET network, there are actually two networks running within the same fiber. The transport network which carries the main stream traffic and the management network which carries SONET NEs’ management traffic.

Figure 9-4 Rear RJ-45 ports Both rear Ethernet ports are 10/100Base-T auto sensing or user configurable. The pinout for both RJ-45 ports is shown in Table 9-1 . These are standard RJ-45 10/100Base-T Ethernet connections and can be connected to using a standard CAT-5 Ethernet cable.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 9: Operations Communications Although the behavior of the R1 and R2 ports are different, both R1 and R2 ports allow the user to setup TN-Relay for remote relay of non-Turin Networks IP-based management traffic and to setup VPN for TNXpert (EMS) connectivity. NOTE: All three Ethernet ports must be on different subnets. NOTE: *In order to use these IP address to gain remote IP access, these IP addresses must be advertised.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 9: Operations Communications 9.2.4 Section Data Communication Channel (SDCC) The Section Data Communication Channels (SDCCs) provide communication connectivity between NEs. All SDCCs are supported through all optical links on the TE-2020 Main Shelf. Both management and control plane traffic can be carried through these data channels and accessed externally via Ethernet interfaces.

Chapter 10 Network Management 10.1 TL-1 Interface Transaction Language 1 (TL-1) is the most widely used management protocol in telecommunications. It manages most of the broadband and access networks in North America and is increasingly being used worldwide for newer management applications. TL-1 is also the preferred Command Line Interface (CLI) for telecom network elements. All TE-2020 NE functionality is supported via TL-1 commands.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 10: Network Management Figure 10-1 Example of a Gateway Node in a Network Typically the communication between the GNE and the subtending NEs is via the in-band DCC. It is very likely that a non-Turin Networks system will interconnect Turin Networks subnetworks. In such case, Turin Networks’ management traffic might not be able to pass through the non-Turin Networks system.
TraverseEdge 2020 Applications and Engineering Guide, Chapter 10: Network Management allows an operator to view the network from different perspectives. Furthermore, the element managing function of TN-Xpert provides complete access to the individual Turin Networks NE that allows the user to remotely manage each node from a central location. TN-Xpert is a client-server based software system.
