Company A is one of the world’s largest brokerage firms. This corporation was founded in 1956
and is known for providing advanced communication services to its brokers, ensuring the fastest
and most reliable communication. The company currently has over 10 million customers who trust
them for the buying, selling, and trading of mutual funds, stocks, and precious metals.
The Company Headquarters (HQ) is located in Manhattan. It has offices in seven cities in the
United States and five international cities. HQ has 3500 employees. Other U.S. locations include
the Chicago office (1200 employees); Miami (450 employees); Boston (820 employees); Dallas
(350 employees); Seattle (350 employees); and Los Angeles (1100 employees). International
locations include Madrid (300 employees); London (200 employees); Paris (300 employees);
Tokyo (450 employees); and Kuala Lumpur (500 employees).
The company uses Cisco routers, switches, firewalls, and intrusion detection, and has installed
Cisco Unified CallManager clusters at all locations. The corporate network uses Microsoft
Windows 2000 Active Directory.
There are two forests. The first forest has two root domains: coa.com and coa.internal. The
second forest root has only one domain: coaasia.com.

There are redundant domain controllers/global catalog servers at each location. DNS and DHCP
servers are also found at each location. The HQ site has two OC-48 connections using HSRP. All
sites have redundant T3s using HSRP to the HQ along with a T1 to every location, providing a
fully meshed architecture. The company uses an Exchange 2000 messaging platform. There are
no planned upgrades to Exchange 2003 at this time.
There are two Exchange organizations: Org1 includes all North American and European servers
and Org2 includes all Asian servers. Both organizations use a single routing group. Org2 has each
city’s Exchange servers in a unique administration group, while Org1 has a single administration
group. Each office has local Internet connectivity, and each office maintains its own Exchange
servers.
The company just upgraded to Cisco Unified CallManager at all locations. Two MCS 7835 servers
are located at each site, except HQ, which has three MCS 7835 servers. There are inter-cluster
trunks established between all subscribers in all clusters.
The company likes the ability to route all intra-company calls over their 3DES encrypted network
links. The existing voice-messaging platform was provided by several different vendors and there
is no networking between them. The company plans to change voice-messaging platforms at all
locations to Cisco Unity. The system will initially be voice-mail-only, but will switch to Unified
Messaging during the next fiscal year. Cisco Unity servers will be placed in each office.
