_ WilTel Network Overview

• WilTel Optical Network Architectural Overview
• Minimum of 96 fibers in every build, with
  multiple conduits at 42 depth, and optical
  amplifiers or regeneration stations approximately
  every 40 miles
• LH and ULH DWDM infrastructure can transmit up to
  1.2 Tbps per fiber, using SONET OC-192 (10 Gbps)
  wavelengths
• DWDM capacity is terminated into optical core
  switches forming an optical mesh which is
  augmented and expanded using regional SONET rings
• Architecture enables provisioning timeframes as
  little as 25 days for OC-48 (2.5 Gbps)
  connections
• 30,000 miles of fiber, reaching 103 U.S. cities
  metro fiber in 65 U.S. cities and 40 MSAs
• Direct access to 540 lit buildings, with almost
  500 more in locations where WilTel has bulk
  facilities
• Relationships with more than 40 competitive
  access providers that add 13,500 off-net access
  points
• Network Operations
• Primary Network Control Center in Tulsa, Okla.
• Backup NCC in St. Louis

_ Interoperability Considerations Roadmap

• Control Plane
• While provider-provider and provider-customer
  GMPLS/UNI interoperability is possible,
  back-office control mechanisms are lagging
• IT control and tracking mechanisms are imperative
  to successful implementations
• Digital Wrapper
• G.709 implementations will vary (different FEC
  codes, overhead byte usage, etc.)
• Interoperability at the OTU layer (minus FEC) is
  the first step
• Data Framing
• PL Ethernet transport across various provider and
  customer networks may require framing/encapsulatio
  n interoperability
• Will provide flexible PL to Ethernet handoff and
  transport options
• GFP and VCAT are the most prevalent but must
  guarantee like-implementations between providers

_ WilTel Optical Roadmap Summary

• Consolidate functions and integrate
  platforms/components where possible to drive down
  cost
• Metro Packet/TDM Integration
• Layer 1/Layer 2 Core Switching Consolidation
• Drive component level integration (Si, InPh)
• Continue to drive efficiency and scalability in
  the core of the network
• Customize bandwidth usage for data centric
  customers
• GFP/VACT/LCAS implementations
• Continue to enable customer control of their
  bandwidth
• Supply higher rate and more data-centric services
  to high bandwidth customers
• 10GE WAN and LAN PHY Transport
• 40G Transport
• Digital Wrapper services
• Automate the customer-provider request process
• Streamline the turn up process through control
  plane implementations
• Ultimately open up a portion of the control plane
  to facilitate dynamic customer control of
  connection, change, disconnect requests
