CBM of America, Inc. “Independent, Intelligent Integrators”…

1. CBM of America, Inc. “Independent, Intelligent Integrators”… Network Mediation, Migration, Integration & Creation Prepared for BellSouth NTM/ BTAS Meeting Charleston, SC January 24, 2006 Michael Stephens, President & CEO Bob Braun, Vice-President EF&I Services South Tom Stilwell, Regional Sales Manager Chris Mount, Branch Manager GA Carl Magnuson, Design Engineer Adaptation : Protection : Skill : Survival

2. Do you know what today is? According to Health magazine, January 24th is the most depressing day of the year. “Health reports that it’s research looked at a variety of emotional, and stress factors, to proclaim Jan. 24, 2006 the years biggest downer day. Apparently, people feel as if there is a shadow over them; with low light levels creating Seasonal Affective Disorder (SAD), holiday bills hitting the mailbox, and New Year’s resolutions already broken, depression is rampant.”. (Palm Beach Post Times 01/22/2006) And you thought it was just because it was another NTM/BTAS meeting! But I know for sure that it really is the margaritas!

3. “Another” CBM IntroductionWhat the heck are we going to talk about this time? • After 15 years of presentations, and three years of BTAS dinners/meetings, how can we make it more interesting? No sales pitch from Mike??? Not a chance, but… • We will try a work shop format this time, with less CBM marketing BS & history, and will do more information sharing.

11. It’s worth mentioning again… CBM knows Cisco too!(Authorized Premier Reseller) • We have been applying the “Datakit Model” to Cisco and it works! • Remember AT&T/Lucent? It’s déjà vu all over again!!! • Combining new and refurbished for the best of all worlds ($$) • Customized Patch Panels & Cables for efficient installations • 24X7X365 Inventory Availability (We ship anytime) • 5 Year CBM Advance/ Exchange warranty (new & refurb) • Pre-provisioning, Rack, Stack & Staging Services are growing • (Deployed over 1200 switches/700 routers in 2005) • As BellSouth’s COWAN network matures, CBM will be there! • (Just like with Datakit, when BellSouth is ready, so will CBM)

12. CSCANS IP Migration Project • CBM has been modifying the CSCANS host software to allow for the eventual migration of facility connected switch applications. This migration will allow switch traffic to ride the BS IP-Based COWAN infrastructure. • In 2005, the DT-4180 16 Port Multi-Protocol Access Device was also enhanced by Datatek to support the Siemens EWSD FTAM Protocol. As a result, of our joint efforts, DT4180’s were deployed in over (60) BellSouth CO’s. • Deployment of DT-4180’s allows for the concentration of diverse switch connectivity (BX25, X25, LTCN, SLM) • The criticality and reliability of the COWAN network is magnified more, now, than ever.

13. CBM SmartCare Support Services BellSouth ATM Corporate Network Problem: • BellSouth was not satisfied with their current supplier of maintenance sparing and parts management for ATM equipment (Lucent CBX500/GX550/PSAX) Solution requirements: • Supplier must have a successful track record of support with BellSouth • Supplier must provide on-line access to parts history and inventory • Supplier must provide on-line trouble call reporting system 24X7X365 • Supplier must provide warehouse space to house BellSouth inventory • Supplier must have services contract with BellSouth • Must be cost effective and efficient Thanks to Michael Vance & Rose Barksdale.

14. Additional Services from www.cbmusa.com Our web based products are growing. • BellSouth Online ATM Parts Inventory Tracking System • BellSouth Online COWAN Order Tracking System • CBM SmartCare Trouble Call Reporting and Tracking (Used for BellSouth BNS/VCS Datakit and ATM Support Contracts) • Online “Search & Quote” Request System (just released)

20. Fiber Driver is NEBS Certified! NEBS LEVEL 3

21. New Product Offerings Authorized “Gold Level” reseller for MRV products • MRV Carrier Class products are Central Office NEBS Certified • In 2004, MRV purchased Luminent Corporation which made it one of the most prominent fiber optic solutions providers in the world • The Fiber Driver Family, has a modular design, has redundant power, and is extremely cost effective. • This device was evaluated, during the CSCANS deployment, for Central Offices where the distance from the DT-4180 to the COWAN 2950 switch connection exceeded the 300’ limitation for ethernet cables. • Unfortunately, this product was not selected because a similar device (Canoga Perkins) was already in use within BellSouth. The MRV Fiber Driver family is more cost effective than the incumbent product. • This is just a sample of the many products that MRV manufactures, IE Terminal Servers, optical transport devices, etc.

22. Fiber Driver T1/E1 & FE with Remote Management • Combines E1/T1 with Ethernet/Fast Ethernet over one Full Duplex fiber optic link - optimizes use of existing fiber plant while extending reach of E1/T1 services • 802.3ah remote provisioning and management - eliminates expensive truck rolls • SFP trunk port interface - change optics as needed quickly and easily • 10/100Base-TX (RJ-45) port with Auto-Negotiation of speed and MDI / MDI-X - plug-n-play connectivity with any standards compliant Ethernet device • Standard T1 (RJ-48) or E1 (BNC) interface - interoperable with standard E1/T1 • Link distance of up to 120+ km over Single Mode fiber - cost effective service deployment over extended distances

23. Fiber Driver 2-Channel TDMs • Transports two Gigabit-speed data channels (GbE or FC) over one bidirectional trunk using a single wavelength – optimizes the utilization of existing fiber plant and available wavelengths • Network transparent operation – does not alter data or packet framing • SFP interfaces – add/change optics as needed, create a WDM wavelength-specific trunk • Trunk link redundancy with <100 ns switchover – eliminates loss of service in the event of primary link failure, essential for mission-critical applications • Applications: Fiber limited installations, Mission-critical services requiring maximum up time, Sub-wavelength aggregation for WDM transport

24. Fiber Driver XFP-to-XFP • Provides XFP-to-XFP interface connectivity • Media conversion • Lambda conversion • WDM • Supports data rates from 9.95 to 11.08 Gbps • SONET OC-192, 10 Gig Ethernet, 10 Gig Fiber Channel, SONET OC-192 over FEC, and G.709. • Delivers Greater flexibility and scalability • Add/Change optics and adjust data rates as needed • Maintain single item inventory • Supports Link Integrity Notification (LIN) • Includes support for XFP specific features: • Digital Diagnostics • XFP loopback and line loopback • Analog hardware monitoring
