VERIZON
WORKS TO RESTORE MANHATTAN SERVICE
Amid the
desperate search for human survivors in New York City, Verizon
began the difficult of job of restoring voice and data services to
probably the most network-intense cluster of buildings in the
world. Amongst the
physical damage is a key switching center at 140 West Street and
adjacent to the World Trade Center which supplies 200,000 voice
lines and the equivalent of 3 million private lines or circuits to
lower Manhattan. Verizon
estimates that this facility provides 20% of all private circuits
to the NYSE. Equipment
was deployed in five underground floors of the buildings and
inspection of only the top floor revealed deep standing water and
extensive debris. Verizon
could not estimate how long it will take to bring the center fully
back online. The
other 80% of private circuits to the NYSE are provided through
another Verizon switching center on Broad Street.
This facility did not suffer heavy physical damage, but has
no reliable power source at the moment.
Verizon also reported that ten Verizon Wireless
cell sites in southern Manhattan are out of service, but demand is
currently being handled by neighboring cells.
During peak periods on Tuesday, Verizon Wireless
experienced 50% to 100% more traffic than normal, nationwide, on
its wireless
network. http://www.verizon.com/

AT&T
LAUNCHES IP-ENABLED FRAME RELAY, ETHERNET ACCESS SERVICES
AT&T announced new classes of service for its private
IP VPNs and its managed dedicated Internet access services.
The IP-Enabled Frame Relay (IPFR) service is based on MPLS-defined
VPNs and four DiffServ priority classes: real time, high priority,
medium priority and low priority. The real-time class is targeted
at such applications as Voice over IP and video conferencing.
The high priority is targeted at mission-critical data
applications, such as Enterprise Resource Planning packages.
AT&T
will also begin offering Ethernet access services to its VPN
services at ranges up to 1 Gbps.
The Metropolitan Ethernet Services will provide access
services to ISPs, ASPs, Storage Area Network (SAN) providers, and
other companies that require metro-area Ethernet service between
locations. This
standards-based, metro-area Ethernet service will initially be
provided at four speeds -- 50Mbps, 150Mbps, 300Mbps and 600Mbps.
AT&T's public Internet Ethernet service is available in
10Mbps, 100Mbps, and 1Gigabit Ethernet speeds and will be provided
as an access option to the company's existing Managed Internet
Service (MIS). The
service initially will be available in New York and San Francisco,
growing to nine cities by year's end.
AT&T
also introduced a private IP access service that lets enterprises
use its global remote dial access service from 2,200 points of
presence in more than 850 cities in 60 countries.
Using Layer 2 Tunneling Protocol (L2TP) customers can use
their current AT&T Frame Relay Service infrastructure for
remote access, eliminating the need for additional VPN access
circuits, routers and modem pools.
Support for narrowband and broadband Internet Protocol
Security (IPSec) encrypted tunnels is being developed and is
expected to be available early next year.
A trial is currently underway.

CABLE
& WIRELESS TO LAUNCH IP VPN SERVICE IN THE US
Cable
& Wireless announced the US availability of a corporate IP LAN
service with IP telephony capability.
The IP-LAN is a managed local area network (LAN) solution,
developed in conjunction with Cisco Systems, which provides
businesses with end-to-end IP connectivity from desktop to
desktop. Cable &
Wireless also introduced a cPBX Plus (convergence private branch
exchange) that is based on Nortel Networks' Meridian PBX.
The service supports conventional telephony, IP Telephony
with VoIP, unified messaging, call center facilities, secure audio
conferencing and management reporting.
Both convergence solutions can be combined with Cable &
Wireless’ IP-VPN, ATM and Frame Relay services to create WANs
provisioned over its MPLS backbone.
Cable & Wireless is already offering the MPLS-based
VPNs and converged PBX services in the UK.
