1-2 Introduction
The OME6130 provides dramatic cost savings over currently deployed
solutions and offers deployment flexibility at multiple levels, including:
• Service flexibility: Full mix of services including 10/100BT (Base-T)
Ethernet, Gigabit Ethernet, E1/DS1, E3/DS3 and STM-1o/e.
• Reach flexibility: Small Form-Factor Pluggable (SFPs) optics are used,
allowing each shelf to be configured for the distance and wavelength
required.
• Protection flexibility: Can be deployed with or without line protection.
Both 1+1 MSP and SNCP network protection protocols are supported.
• Interoperability flexibility: Can be networked either with other
OME6130 or OME6110 network elements, or subtended from other Nortel
optical products, such as OM4000 or OME6500.
• Management flexibility: The OME6130 is fully integrated into Nortel’s
Optical Application Platform with OMEA. The OME6130 can also be
managed from an HTTP web-based craft user interface running on the
network element. In addition, SNMP alarm traps are supported, enabling
OME6130 fault management from SNMP management systems.
• Data communications flexibility: The OME6130 can be managed over
either OSI or IP DCN networks. Path DCC capabilities are also provided
for extending management reach over third-party networks.
The OME6130 is a carrier grade platform that builds upon the solid reputation
for dependability of Nortel Networks' widely deployed optical networking
products. The various protection options offered by the OME6130 further
enhance the dependability of service transport. For access head end
applications, service traffic can either be connected via sub-network
connection protection (SNCP) or via protected point-to-point 1+1
connections.
Optical Multiservice Edge 6130 NT6Q92MA Rel 1.0 Iss 1 Standard September 2006
OME6130 applications
The OME6130 offers significant value across a range of network applications.
The principal OME6130 applications are:
• Feeder for Metro Optical networks: The OME6130 can be subtended
from Nortel’s larger Optical platforms to collect 10/100BT Ethernet,
Gigabit Ethernet, E1/DS1, E3/DS3 and STM-1o/e traffic from the Access
Edge. Its compact footprint and low price make it well suited for smaller
customer locations. The OME6130 can be subtended either in a SNCP or
1+1 MSP configuration. The capability to manage OME6130 using path
DCC bytes also allows it to be managed remotely over leased
STM-1/STM-4 circuits. The Regenerator Section and Multiplexer Section
overhead tunnel capability provides further flexibility in managing other
SDH equipment within the same ring.
• Private Enterprise Networks: The OME6130 can be deployed in smaller
private networks providing transport of 10/100BT Ethernet, Gigabit
Ethernet, E1/DS1, E3/DS3 and STM-1o/e services between sites. A light
weight management solution is available for such applications consisting
of a web-based craft interface running on the OME6130 for NE
provisioning and SNMP north bound interface for reporting alarms to a
generic SNMP alarm browser.
Introduction 1-3
• Wireless Backhaul: The OME6130 is also well suited for wireless
backhaul applications where both space and cost are paramount. The
OME6130 can be used as a cost-effective backhaul of today’s E1/DS1s and
will support the 3G network transition to Ethernet.
OME6130 service interfaces
OME6130 offers transport and aggregation of asynchronous private lines,
SDH, and Ethernet. The OME6130 shelf has four (4) universal tributary slots
and supports a full mix of tributary interfaces. The OME6130 supports three
basic categories of interface:
• 10/100BT (Base-T) Ethernet and Gigabit Ethernet
— The tributary slots can be equipped with the 8x10/100BT L1 Ethernet
and 2xGE L1 circuit packs. The 8x10/100BT L1 Ethernet circuit pack
supports 8 10/100 Base-T Ethernet Private Line (EPL) ports and the
2xGE L1 circuit pack supports 2 Gigabit Ethernet (GE) EPL ports.
• PDH
— The tributary slots can be equipped with the 28xE1/DS1 and 3xE3/DS3
circuit packs. The 28xE1/DS1 circuit pack supports 28 E1/DS1 ports
and the 3xE3/DS3 circuit pack supports 3 E3/DS3 ports.
•SDH
— The tributary slots can be equipped with the 2x155M circuit pack. The
2x155M circuit pack supports 2 STM-1 optical / electrical (o/e) ports.
Planning Guide NT6Q92MA Rel 1.0 Iss 1 Standard September 2006
1-4 Introduction
Small form-factor pluggable interfaces
The OME6130 uses small form-factor pluggable (SFP) interfaces to deliver
optical rate and reach flexibility on a per port basis for the line interface. The
OME6130 also supports electrical SFP for the STM-1e interface.
The OME6130 offers the following SFP interface types:
SR-0, I-1.1/I-4.1, S-1.1/S-4.1, L-1.1/L-4.1, L-1.2/L-4.2, CWDM, STM-1 BX,
STM-1e, GE SX and GE LX.
Nortel Networks has been collaborating closely with leading SFP vendors to
improve the reliability, robustness and manageability of SFPs. The use of such
carrier-grade SFP technology enables service providers to enjoy the flexibility
of provisioning the interfaces per the requirements of the specific application.
SFPs also reduce the cost of sparing by enabling an upgrade of the optical line
interfaces as they become readily available.

Point-to-point optical broadband services
The OME6130 uses GFP, VCAT and LCAS standards for the mapping and
transport of Ethernet services.
GFP provides an efficient mechanism for Ethernet transport over a SDH core
network via efficiently mapping varying client signals into SDH VC-12, VC-3
and VC-4 frames. GFP mapping enables efficient network resource utilization
with low overhead requirements, and limited over-provisioning with VCAT.
End-to-end framing provides demarcation for the Ethernet signal, and enables
consistent SDH based PMs through the network. Since the Ethernet is mapped
into SDH frames, the existing core network can transport the Ethernet frames
transparently.
(STM-1/STM-4)
Optical Multiservice Edge 6130 NT6Q92MA Rel 1.0 Iss 1 Standard September 2006
Introduction 1-5
The OME6130 also supports Virtual Concatenation (ITU-T G.707 compliant)
with support at the VC-12-nv, VC-3-nv and VC-4-nv SDH rates. A maximum
of 48 ms of differential delay is supported.
Along with VCAT the OME6130 also supports value added capabilities such
as soft protection via Link Capacity Adjustment Scheme (LCAS - G.7042).
LCAS has been specifically developed to overcome static link provisioning. It
enables service providers to efficiently offer dynamically-allocated bandwidth
as well as hitless throttling of the capacity of a VCAT link (or Virtual
Concatenated Group) by adding or removing VCs as required.
LCAS provides a soft protection and load-sharing mechanism to automatically
decrease the link capacity if a VC path experiences a failure and automatically
increases the link capacity when the network fault is repaired. This capability
provides an extra level of network and service resiliency by facilitating the
support of SLAs through graceful service degradation when necessary. In
particular, during network and service restoration LCAS can support hitless
bandwidth expansion and contraction thereby reducing service interruptions in
the event of network failure and easing network operations and maintenance
actions.
TDM switching
In the OME6130 architecture, traffic is switched between working and
protection line interfaces via the switch matrix in the 2x155/622M aggregate
circuit pack.
All ingress service traffic is mapped into VC-11, VC-12, VC-3 or VC-4
containers and directed towards the switch matrix which is configured to
switch the incoming traffic to the appropriate line interface. The switch matrix
allows any input channel to be connected to any output channel. Hairpinning
is also supported between client ports.
Network management
The OME6130 is managed as an integral part of Nortel Networks' market
proven end-to-end optical portfolio management capabilities. This framework
supports a sophisticated and highly customizable desktop providing
centralized topology view and fault management, centralized launch pad for a
full suite of management applications, easy to use nodal managers and
seamless network element reach-through for Nortel Networks' complete
optical networks portfolio. These network management capabilities are
supported by the Optical Manager and Optical Application Platform, such as
OMEA and Optical Network Manager (formerly known as Preside), in
alignment with Nortel Networks overall optical networks portfolio.
Planning Guide NT6Q92MA Rel 1.0 Iss 1 Standard September 2006
1-6 Introduction
The OME6130 local craft access terminal, which is an HTTP web-based
graphical interface running on the network element, provides complete nodal
management that can be integrated into a centralized network wide view
through the Optical Application platform.
Key features and benefits
The OME6130 multi-services access platform provides customers with the
flexibility, scalability and management capabilities they need in a compact
cost effective package. The key benefits to customers of deploying the
OME6130 can be summarized as follows:
• support of a broad set of services (Ethernet, PDH/Async and SDH)

2-10 Feature overview
System Line-up and Test (SLAT)
This release supports the ability to configure the system when it is being
commissioned for the first time. The user is given an option to initialize the
system with a configuration compatible with the NE.
The node capability is provisioned to either STM-1 or STM-4 during initial
commissioning. The two SFP interfaces of the 2x155/622M aggregate circuit
pack are operating at the rate of the node capability value.
For more information, refer to System Line-up and Test (SLAT) on page 6-2
Configurations
OME6130 currently supports the following configurations for the STM-1/4
line interfaces.
1+1 MSP protection
OME6130 supports 1+1 Multiplex Section Protection (MSP) configurations.
For more information, refer to 1+1 MSP on page 3-1.
SNCP
OME6130 supports Sub-network connection protection (SNCP) ring
configurations.
In a SNCP configuration, traffic is transmitted simultaneously on two separate
ports. The traffic is transmitted via different routes through the network to the
destination node which selects one of the two paths based on the quality of the
received signal. For example, in a ring configuration, the traffic can be
transmitted simultaneously on the working fiber in the clockwise direction and
on the protection fiber in the counter-clockwise direction.
For more information, refer to SNCP on page 3-1.
Unprotected
OME6130 supports unprotected configurations. For more information, refer to
Unprotected configuration on page 3-2.
Optical Multiservice Edge 6130 NT6Q92MA Rel 1.0 Iss 1 Standard September 2006
Connection management
OME6130 supports nodal port-to-port connection management. OME6130
supports the ability to provision bidirectional and unidirectional connections
at VC11, VC12, VC3, and VC4 rates.
OME6130 Release 1.0 supports various bandwidth management models that
include the following;
• bidirectional connections
• unidirectional connections
• port to port (hair-pinning)
• drop and continue
Note: Only bidirectional connection type is supported for WAN ports
corresponding to the 10/100BT Ethernet and Gigabit Ethernet ports.
For more information, refer to Connection management on page 6-13.
Service mapping
All services (Ethernet, E1, DS1, E3, and DS3) are mapped to appropriate SDH
containers.
Feature overview 2-11
The OME6130 uses Generic Framing Procedure (GFP) as its standards based
SDH mapping for Ethernet services. GFP is an ITU standard (G.7041) which
describes a flexible mapping technique for transparent transport of multiple
protocols in SDH. GFP-Framed (GFP-F) is used for mapping Ethernet to SDH
tributaries and containers.
Table 2-3 provides a summary of the service mappings supported in this
release.

2-12 Feature overview
Traffic protection
OME6130 supports 1+1 MSP and SNCP traffic protection. The system
monitors the traffic facilities for performance degradation and failure and
performs protection switching when these conditions are present. Table 2-4
provides a summary of the protection schemes supported in this release.

• 28xE1/DS1 circuit pack
• 3xE3/DS3 circuit pack
Unprotected
(default for all supported
interfaces)
For more information, refer to Traffic protection on page 6-17.
Synchronization
Synchronization is a network level application that ensures all nodes across a
network can trace back to the same clock source. Within a single node,
synchronization prevents buffer overflow or underflow which avoids bit
errors.
For more information, refer to Synchronization management on page 6-7.
Alarms and events
The OME6130 provides several mechanisms to identify and localize faults and
events.
• light-emitting diodes (LEDs) on the faceplate of a circuit pack indicate the
status of the functionality supported on the equipment
• STM-1/4 interfaces
• 8x10/100BT L1 circuit pack
• 2xGE L1 circuit pack
• 28xE1/DS1 circuit pack
• 3xE3/DS3 circuit pack
— circuit pack failed on all circuit packs
— loss of signal on interface circuit packs
— power LED on the OAM circuit pack provides the power status
