The Background and Setup of BANC

B.A.N.C. Financing International is a multinational financial institution headquarted on the East Coast of the United States. It provides mortgage lending, brokerage accounts, and other financial services, and it has offices throughout the United States, as well as in Europe and Asia.

Like many businesses within the financial industry, it is quickly moving into new markets through expansion and mergers with other financial institutions. It recently acquired two small banks in the United States and plans to add three or four financial services groups in Europe and Asia within the next 18 to 24 months.

B.A.N.C. currently provides loan and mortgage rate details to customers through its Web page, but it wants to offer additional services through the Web. It also wants to reduce its customer service costs.

B.A.N.C.'s existing data network comprises about 50 percent TCP/IP, 35 percent Systems Network Architecture (SNA), and 15 percent Internetwork Packet Exchange (IPX) traffic. Its data infrastructure is made up of Cisco routers and switches, and it is actively working to enable quality of service (QoS) on its campus local-area network (LAN) and wide-area network (WAN) backbone in anticipation of future multimedia applications. As it acquires new companies, it standardizes on Cisco routers and switches and removes any protocols other than IP, IPX, and SNA.

In the future, B.A.N.C. hopes to transition its IPX servers to TCP/IP so that it can consolidate on two protocols. The majority of its traffic consists of intraoffice communications between loan officers and the IP or SNA databases at headquarters. Its WAN is made up of an international Frame Relay backbone; most sites have 256 Kbps circuits with 128 Kbps committed information rate (CIR).

B.A.N.C.'s voice network was initially made up of a single PBX vendor with remote key-systems, but with its recent acquisitions it also acquired PBX technology from other vendors. Although it can still provide telephony services, B.A.N.C. cannot provide feature transparency between the different PBX vendors. All its remote sites use leased lines to interconnect the branch offices with the headquarters PBX and voice-mail system. Some of these remote connections are full T1 lines, and others are fractional T1 lines. A representative diagram of B.A.N.C.'s existing network is shown in Figure 15-1.
