Blended MPLS – Industry Firsts• MPLS over ADSL

– Up to 6 classes of service on ADSL– Honored edge-to-edge– Flexible tagging options– Seamless integration into MPLS T1 network

• MPLS over Wireless Data– Alternative to high-priced fill in– Wireless and terrestrial network on one contract– Perfect for backup: True diversity without wireline– Nationwide 3G Network– Secure and private

• Never touches the public Internet• CDMA standard

– Comparable to DSL speeds• Download speeds between 400-800 Kbps• Upload speeds between 300-400 Kbps

11

Backup Options Overview

• The router will use a dynamic routing protocol or other mechanism to determine that the primary access has failed

• The backup access will be activated (if required)• Traffic will then be sent over the backup access

12

MPLS over Wireless Data Wireless data access fills a gap between high priced or low speed solutions and it provides true diversity from traditional wireline (loop-based) services. The diagram below illustrates wireless access

.

New Edge Networks and Deltacom have combined to form EarthLink Business.

15EarthLink SIP Trunking: Overview

EarthLink SIP Trunking uses Session Initiation Protocol signaling and a native IP-based facility to manage all voice traffic between a customer's IP PBX platform, EarthLink MPLS or public network, and the Public Switched Telephone Network (PSTN).

Features include:• Secure, redundant, carrier-class infrastructure• Standard or aggregate trunking configurations• Comprehensive service features, including local/LD/toll-free, caller ID,

E911• Network flexibility, with delivery over multiple access types• Seamless, integrated failover and disaster recovery• Efficient management and reporting with MyLink portal• End-to-end implementation support including site-by-site porting

16EarthLink SIP Voice Infrastructure

• Nationwide IP Network– Cisco Core (CRS1), Cisco Edge (7600)– MPLS Backbone used to route voice and

data traffic with CoS

• Call switching– Universal Media Gateway (UMG)

Class 4 switching (Tandem / Trunking)Class 5 switching (Features)

− MetaSwitch Call Feature Server (CFS)Class 5 features provided by PBX in trunking environment

• Enhanced feature server− MetaSphere Enhanced

Application Server (EAS)

• SIP security and control– ACME Packets Session Border

Controller (SBC)Secure messaging for customer-facing and internal networks; management and control of SIP behavior on a per deployment basis

• End-to-end call flow monitoring; VOIP/SS7 probes− Empirix

17SIP Business Continuity

• Load Balancing– Balance traffic between Birmingham and Colorado

• Physical Layer Failover– Automatic failover between trunking into datacenters– Each datacenter connection capable of supporting

entire load

• Auto Reroute– Automatically reroutes traffic to another number if

primary connection is lost

18Network Management and Maintenance

• Highly integrated NMS systems• 24x7 monitoring & alerting

– Pings the customer WAN IP address every 5 minutes– Unacknowledged pings automatically opens a service ticket – Customer alerts via phone /email/text, and MyLink interface
