2. Tellabs 7100/7100N Optical Transport Series
2.01 This section provides an overview of DWDM systems and the Tellabs
7100/7100N OTS operations.
DWDM and the Optical Layer
2.02 Dense wavelength division multiplexing (DWDM) is an optical technology
used to increase the capacity and flexibility of the optical infrastructure. In a DWDM
system, multiple optical signals are transmitted over multiple optical wavelengths
on a single optical fiber. Traditional systems require multiple optical fibers to
transmit multiple optical signals.
2.03 DWDM is a multiplexing hierarchy that leverages the optical layer of the
transmission network. The optical layer interfaces the digital layer at the optical
termination equipment, which can be considered part of both the electrical and the
optical layer. The optical layer provides multiplexing schemes and management
that are not present on the digital layer of the network.This optical infrastructure
supports multiple data rates (for example, 622 Mbps, 2.5 Gbps, 10 Gbps),
synchronous optical network (SONET) signal rates, and synchronous digital
hierarchy (SDH) signal rates.
2.04 DWDM systems are divided into integrated and open systems. In
integrated DWDM systems, the DWDM transmitter and receiver functionality is
integrated into the transmitter/receiver of the digital transmission equipment. In
open DWDM systems, special DWDM transmitter/receiver interface units
(transponders) are used to provide the interface between the DWDM multiplexers
and the adjacent digital transmission equipment.
Multiplexing Schemes
2.05 In DWDM systems, the signals to be multiplexed and demultiplexed are
characterized by different optical wavelengths. The optical wavelengths of the
Tellabs 7100/7100N OTS are chosen in agreement with the International
Telecommunications Union (ITU-T) recommendations specifying up to 44 DWDM
channels with center wavelengths placed in the erbium doped fiber amplifier
(EDFA) gain band with 100 GHz between neighboring channels, and 88 DWDM
channels with center wavelengths placed in the erbium doped fiber amplifier
(EDFA) gain band with 50 GHz between neighboring channels. Wavelengths are
placed from 1529 nm to 1563 nm, where the EDFA gain bands exhibit the most
wavelength uniform gain characteristics.

76.7144FP51/2, Rev B 5/09 Page 2-3
Layer Management
2.06 The optical layer is managed as the digital (SONET/SDH) layer is, except
for the physical transport of remote management data. In the optical layer,
supervisory and management data from remote DWDM equipment cannot be
transmitted over embedded digital channels. Instead, this data is transmitted over
an independent optical supervisory channel (OSC) at 1510 nm. The OSC is
terminated, processed, and retransmitted at the DWDM equipment that interfaces
the optical transmission fiber.
Tellabs 7100/7100N OTS Operations
2.07 The Tellabs 7100 OTS is a metro, dense wavelength division multiplexing
(DWDM) system based on a parallel architecture that provides scalable,
non-service affecting growth to 88 protected wavelengths without network
re-engineering. The Tellabs 7100N OTS is a full-featured system providing eight
protected wavelength for niche applications within a Tellabs 7100 OTS network.
These systems support ITU-T Recommendation G.709 Optical Transport Network
(OTN)-based transport, enabling transparent high-capacity services. Services
such as Carrier Ethernet, video, Storage Area Network, SONET, and SDH are
carried on a shared infrastructure, scaling capacity as needed.
2.08 The Tellabs 7100/7100N OTS is built on unique, multi-patented system
technologies that enable true next generation multiservice delivery. It features an
integrated dynamic optical core combined with an intelligent services interface that
delivers Add/Drop Multiplexer (ADM) capability on a single blade (SMTM-U
module) in client ranges of 100 Mbps to 40 Gbps. The dynamic optical core
enables service providers to meet today’s network needs while supporting the
ability to effortlessly deploy additional nodes for future expansion via a
multi-degree Reconfigurable Optical ADM (ROADM).
2.09 The intelligent services interface can replace a currently installed ADM ring
with a simple pair of modules, eliminating the costly implementation of stacked
ADM rings, back-to-back ADM boxes between rings, and multiple rows of
supporting equipment. Linear add/drop, ring, and mesh optical network topologies
are supported on the same base platform. Service is easily changed by equipping
endpoints with specific interface modules.
2.10 Tellabs 7100/7100N OTS provides the following benefits:
• fiber relief in fiber-constrained networks
• wavelength and capacity-based services
• deployment of new services without re-engineering networks
• efficient aggregate and transport of different types of traffic in
metropolitan (metro) areas
• variable applications such as mesh, ring, and point-to-point

2.15 Tellabs 7100/7100N OTS supports the following 44- and 88-channel
network configurations in FP5.1.x:
2.16 The following network configurations are supported:
__ Tellabs 7100 Single Bay OADM (SBOADM) - The Tellabs 7100 OTS
single bay optical add/drop multiplexer (SBOADM) is a single network
element with multiple DWDM interfaces. A four-degree SBOADM
requires one main shelf, supports up to eight port shelves, and
operates within a 44-channel plan. An eight-degree SBOADM requires
two main shelves and supports up to eight port shelves, and operates
within a 44- or 88-channel plan.
__ Tellabs 7100 Optical Line Amplifier (OLA) - a 44- or 88-channel OLA
can be configured for short, medium, or long spans. The OLA does not
support add/drop functions, but can be upgraded to a 2-degree node
SBOADM without affecting traffic.
__ Tellabs 7100N OTS SBOADM - the main shelf has up two DWDM
interfaces, A-side through B-side and supports eight protected
wavelengths. The Tellabs 7100N OTS SBOADM is supported only in
44-channel systems.
__ Tellabs 7100N OLA - a 44- or 88-channel OLA can be configured for
short, medium, or long spans. The OLA passes through up to 44
channels and does not support add/drop functions. This OLA is
interchangeable with Tellabs 7100 44-channel OLA.

Embedded Operations Channel Network
2.18 The Embedded Operations Channel Network (EON) provides Embedded
Operations Channels (EOCs) to route management traffic using Internet Protocol
(IP) through an internal network among the NEs.
2.19 One NE in the EON is provisioned as a gateway NE (PGNE-1) and routes
management traffic between the external DCN and the other NEs (PRNEs) in the
EON. The PGNE-1 manages PRNEs through the Tellabs 7190 EMS and Tellabs
7194 NMS, acting as an entry point from the external DCN and enables packet
routing among the PRNEs after an IP address is configured for each. A secondary
gateway (PGNE-2) provides redundancy so that a single optical link failure does
not cause a communication interruption between the Tellabs 7190/7194
management systems and any NE in the ring.
2.20 Tellabs recommends limiting to 30 the number of PRNEs assigned to a
PGNE. When a network exceeds this limit, the EON can be partioned into two
EONs by provisioning one of the PRNEs as a second PGNE-1 and modifying the
traffic paths around that PRNE. Refer to the Tellabs 7100/7100N Craft Station User
Guide for detailed procedures on partitioning NEs. Figure 2.2, page 2-7 illustrates
the resulting two EONs interconnected via DWDM links after partitioning.

Autodiscovery
2.21 Autodiscovery is a self-inventory feature that enables the Tellabs
7100/7100N NEs to report their inventory to the Tellabs 7190/7194 management
systems. On system startup, the NE performs a self survey to determine which
hardware components are present. This information is retrieved by the system
manager when it is connected to the NE. If there is a discrepancy between the
configurations stored by the management system and the NE, the NE is assumed
to have the valid configuration.
Performance Monitoring
2.22 Performance monitoring is the continuous, nonintrusive collection of
system performance data and is used to determine the operational status of the
network and the quality of service that the network is providing. PM checks for
specific types of signal information and helps identify the cause of network
transmission problems. PM is detailed in Facility Performance Monitoring,
page 2-106.
Control Plane
2.23 The Tellabs 7100 OTS Control Plane feature provides rapid circuit
provisioning across mesh architectures in transport networks. Control plane
functionality is based on the ITU-T automatically switched optical network (ASON)
architecture and utilizes IETF generalized multi-protocol label switching (GMPLS)
protocols as extended by the OIF. It is embedded in the SPM and applied at STS
or VC termination points on paired SMTM-U module facilities operating in SPFAB
mode.
2.24 NEs are network aware in control plane applications, providing faster
set-up and tear-down of call paths across the network. The call path is established
at the STS or VC layer. The control plane automatically manages a link resource
database in real-time to provide constraint-based routing and traffic engineering.
The Tellabs 7100 OTS control plane application interfaces traditional and
management plane systems to coordinate traffic and network resources.
2.25 Tellabs 7100 OTS Control Plane supports calls across multiple domains
and flexible path protection at the STS/VC level. Re-designed protection schemes
in FP5.1.x streamline provisioning requirements while enhancing reliability to
control plane traffic.
2.26 Control Plane 1+1 (CP 1+1) protection provides two diverse connections
(working and protected) between the ingress node and the egress node of a
protection domain. This protection scheme is supported on the drop-side and the
line-side between Tellabs 7100 OTS NEs within the Tellabs 7100 OTS control
plane network (I-NNI). CP 1+1 protection is not supported on drop-side or line-side
facilities provisioned between a Tellabs 7100 OTS NE and control plane entities
outside of the Tellabs 7100 OTS network where only LAPS is supported over the
E-NNI.

General Description 2. Tellabs 7100/7100N Optical Transport Series
76.7144FP51/2, Rev B 5/09 Page 2-9
2.27 Flexible Path Protection is a protection scheme that removes previous
shelf-slot pairing constraints and enables protection port pairing between any two
ports on the line side, or any two ports on the drop side. It allows any port-side
termination to be protected by any other port-side termination and any line-side
termination to be protected by any other line-side termination within the same shelf.
Protection port pairing with a line-side port and a drop-side port mixed pair is not
supported. A protection port pair constitutes a Path Protection Group (PPG)
supported by STSn/VCn path layer protection. These Path Protection Groups
(PPG) are automatically created when the cross-connect is provisioned. For CP
1+1, two PPGs are created – one at the ingress/source node, and one at the
egress/destination node.
2.28 Dynamic re-route supports multiple repair points for a signal path and
permits automatic recovery from node failures with an efficient use of resources
that are used only during route restoration, unlike Control Plane 1+1 (CP 1+1)
protection where resources are pre-allocated. Dynamic re-route is supported in
single domains and across multiple domains. When dynamic re-route restoration
is provisioned, failure indications are propagated to repair nodes to direct an
alternate route connection to bypass the call path. In the event of resource
contention among multiple dynamic calls or simultaneous failures along the call
path, crankback is used to address these conditions and retry failed calls.
Ethernet Packet Support
2.29 Packet subsystems are created on Tellabs 7100 OTS port shelves when
packet modules (DPM, SPFAB, SMTM-P, and TGIM-P) are present and
provisioned. Packet subsystems are created on Tellabs 7100N OTS port shelves
when SMTM-P or TGIM-P are present and provisioned. The Packet subsystem
can be managed with the Tellabs 7190/7194 management system or a Command
Line Interface (CLI). Packet-based transponder modules, SMTM-P and TGIM-P,
manage the ingress and egress ports for traffic flow. SMTM-P modules are
equipped with small form pluggables (SFPs) designed to support traffic signal rates
that interface the module. Refer to Table 2.1, page 2-9.
2.30 Supported features include MAC Bridging, VLAN Bridging, an 802.3
compliant MAC client interface, Packet security, Packet fault management, Packet
performance monitoring, multicasting, synchronized Ethernet, and line-side RPR
protection.

2.31 In Tellabs 7100 OTS applications, the SONET/SDH/Packet Fabric
(SPFAB) module provides a switch matrix for SONET/SDH signaling and Packet
traffic to maximize system integration and bandwidth efficiency. It interfaces
SMTM-U, SMTM-P, and TGIM-P modules to switch Packet and STS/VC-level
cross-connects.
2.32 Packet applications support both SNMPv2 and SNMPv3. Quality of
service certifications include Metro Ethernet Forum (MEF) services certification:
E-Line service, E-LAN service, and Ethernet Private Line (EPL). Performance
monitoring enhancements include Weighted Random Early Detection (WRED)
congestion management, traffic-shaping queues, and continuity checks.
2.33 Improved fault management for 802.3 compliant MAC/PHY interfaces
include Far End Fault Indication (FEFI) for 100FX interface, LOSYNC for NE IEEE
802.3 compliant MAC interface, signal degrade and signal fail conditions detected
on incoming Ethernet traffic based on errored frames, provisionable alarm profiles,
and additional alarms and conditions retrieved via SNMPv2c traps.
2.34 Traffic enhancements include tunneling Layer 2 control frames
transparently (spanning tree bridge protocol data units and GVRP packets) at
Provider Edge Bridge points. Ethernet types are filtered at the module port to
reduce congestion. Link aggregation groups are managed by SNMPv2.
SDH Protocol Support
2.35 A suite of Tellabs 7100 OTS and Tellabs 7100N OTS features are provided
in SDH signaling formats. Transparent STMnT (Synchronous Transfer Mode)
signals are introduced to multiplex SDH-based traffic onto a single fiber to reduce
fiber exhaust. STMnTs transport Virtual Containers (VC-4, VC-4-4C, or VC-4-16C)
through the network untouched.
2.36 This feature also uses VCn grooming to support multiple types of traffic,
including virtual concatenation. This utilizes the capacity provided by DWDM
applications and eliminates the requirement for distinct ADMs. Within the Tellabs
7100 NE, distinct VCs may be individually cross-connected onto different STM-xs,
which are associated to DWDM channels. Cross-connect terminations VC-4,
VC4NV, VC-4-4C, and VC-4-16C are supported. Signals can be concatenated into
groups via VC4NV (Level 4 Virtually Concatenated) facilities for provisioning and
transport.
2.37 CRC4 framing format and E1 signaling are also supported. Signal
protection is provided in both 1+1 protection and SNCPRING protection schemes.
Graphical representations of both world maps and actual operating NEs are
provided for visual provisioning.
Note: In SDH standards, it is possible to support either high order VC-3 or low
order VC-3 (TUG3 mapping). The Tellabs 7100/7100N OTS only supports
high order VC-3 path layer entities per ITU-T G.707. Customer
provisioning and use of VC-3 should carefully consider ITU-T
recommendation for Multiplexing of AU-3s via AUG-1 (refer to ITU-T
G.707/Y.1322 12/2003 Figure 7-4) in order to avoid any interruptions in
traffic.

Interoperability Features
2.38 Interoperability features are built in to the Tellabs 7100/7100N OTS for
seamless integration into multiple vendor network.
Data Communications Channel (DCC)
2.39 DCC allows the messaging specific to multi-vendor devices in a Tellabs
7100 network to flow through the Tellabs 7100 NE that is provisioned as the
network Gateway Network Element (GNE). The GNE serves as a conduit for
communication between non-Tellabs management systems and the sub-tending
multi-vendor devices they support, allowing both messaging and software
downloads via an OSI-based Data Communication Network. DCC processing
routes messages between the DCN interface, the SPM, the DPM, and the DCC
interfaces on the SMTM-Us.
IP Over DCC
2.40 IP over DCC allows subtended SONET/SDH platforms to access an
IP-based DCN. On the Tellabs 7100 OTS, it allows access to the signaling
communication network (SCN) in control plane applications. IP traffic presented
over the DCC may be locally processed or forwarded to another PRNE or to the
PGNE.
2.41 Establishing an SCN expedites traffic processing by directing signaling
and management traffic to different physical ports on the NE. The SCN on the
Tellabs 7100 OTS is established via OCn, VCn, and HDP port provisioning.
OSI Traffic Tunnelled Over EON to Remote NEs
2.42 The management functions of GNEs can be extended to SDH/SONET
ADMs that subtend remote Tellabs 7100/7100N NEs by tunneling OSI traffic over
the EON to allow the PRNE to serve as a single GNE in the SDH/SONET ADM
subnetwork. The NE supports up to 64 OSI associations per TCP session and up
to 15 TTD TCP sessions.
Services Between Transponders and External Equipment
2.43 The ROADM/SBOADM DWDM optical network components in a Tellabs
7100/7100N OTS application can be decoupled in Tellabs 7100 OTS networks so
that Ethernet, SONET, and SDH capabilities can be deployed without routing
through mutiplexing functions on the NE. This flexibility simplifies provisioning and
reduces start-up costs for smaller applications while preserving the capability to
upgrade to ROADM/SBOADM DWDM services.

System Operation and Growth
2.44 This section provides general descriptions of features related to growing
and modifying a Tellabs 7100/7100N OTS.
SPM Operation
2.45 The 71114B System Processor Module (SPM) and 71714 System
Processor Module (SPM-N) automatically validate their NE location at each restart.
This ensures that the supporting NE is not reprovisioned with an incorrect
configuration during an SPM replacement.
2.46 To facilitate module replacement, the SPM/SPM-N stores module
commissioning parameters and configuration data in the NE database located on
the redundant SPM (and redundant SPM-N when present). This functionality
allows the SPM/SPM-N to automatically restore its commissioning and
configuration data when a module is replaced.
Auto-Negotiation
2.47 Auto-negotiation is provided on the SMTM-U to facilitate signal transport
across a network. With auto-negotiation, the SMTM-U can communicate its
transport properties, such as speed and duplex mode, to routers in the network so
the two devices can determine the most efficient transport mode supported by
both. On the SMTM-U, auto-negotiation is managed on the GbE facility.
Performance is monitored through maintenance signaling on the client side.
Seamless Expansion
2.48 Additional degrees can be added to expand current nodes without
reprovisioning wavelengths and 44-channel OLA configurations can be converted
to 44-channel SBOADMs.
2.49 Amplifiers, RCMM-4Ds, and RCMM-8Ds can be replaced with
corresponding modules of increased capacity or features without impacting
currently provisioned wavelengths, facilities, or cross-connects.
