In Reading, the router also sees that the packets are heading for Bechtelsville. Its LCR table tells it to route the call over this last hop via frame relay, not IP. The call finally reaches the Bechtelsville router, which connects through a standard E&M port to the Bechtelsville Comdial FXS. The Comdial FXS, knowing that extension 2001 is a voicemail port, sends the call to the Key Voice voicemail system out of an IRST port. The voicemail system picks up, Mary presses the # key and her extension. This sends the call to her mailbox, asks her for her password, and then plays her voicemail to her back down the chain.

The crown jewel in Microsoft's embedded push is Windows CE 3.0, which will ship in June with enhanced real-time features, a full-blown Internet Explorer 4.0 browser and support for Microsoft's DirectX multimedia application programming interfaces, Universal Serial Bus, smart cards, Simple Network Management Protocol and an HTTP server.

The upgraded browser will support HTML 4.0 forms, frames and floating frames, and, with a few limitations, Cascading Style sheets and Dynamic HTML. However, the enhanced browser requires about 3 Mbytes on an X86 PC, compared with 1.3 Mbytes for the current Pocket Internet Explorer. On other, less-code-dense RISC processors, the footprint will be even larger.

In real-time, CE 3.0 will support 256 priority levels, nested interrupts and a tweaked kernel with significantly reduced interrupt service routing (ISR) and interrupt service thread (IST) latencies. The latter will vary based on processor and implementation. As a benchmark, Microsoft said a system using a 166-MHz Pentium could expect ISRs of 10 microseconds and ISTs of 100 s.

Not mentioned was preemptive latency, the key time required for context switching between program threads.

A coherent strategy” Analysts agreed last week that the moves amount to an important step forward for Microsoft. It's long overdue,” said Paul Zorfass, a senior analyst for International Data Corp./FTI. They haven't had the concerted and focused effort they needed to be successful. And this will be a concerted and focused effort.”

For the first time, Microsoft seems to have a coherent strategy on how to position Embedded NT and CE,” concurred Daya Nadamuni, an industry analyst at Dataquest Inc. (San Jose, Calif.).

Zorfass described Microsoft's previous products as learning efforts.” Micro-soft has failed to capture the embedded market the way it had hoped. Zorfass believes that's because the company was too wrapped up in PC- and service-oriented models, and failed to fully understand the markets it was entering. It took more than they realized to succeed in diverse and heterogeneous marketplaces,” he said.

Even competitors had mild praise for the Windows giant. They are making fairly natural but modest steps toward serving this industry,” said John Fogelin, vice president of the platform group at Wind River Systems Inc. (Alameda, Calif.), Microsoft's biggest embedded competitor.

But Microsoft has a long road ahead. In a survey last year of 5,000 EE Times readers who were embedded-systems developers, Windows CE fell dead last in a group of 12 embedded OSes in current use, with only a couple of percentage points of market share. Wind River's VxWorks was the leading commercial product with about 25 percent of the market, although in-house OSes took the majority at about 58 percent.

CMC strongly emphasizes building and maintaining relationships. It dedicates agents to each client and trains them so they become part of the client's front line. CMC encourages agents to refer to themselves as the client's employees. The service bureau even sent agents to one client's branch in Memphis to observe how it operated and to gain a better understanding of the client's customers.

The service bureau is in the process of growing from 200 to 300 seats, and it is also expanding its services to accommodate its clients' on-line customers. CMC began handling text chat requests for a business-to-business client earlier this year.

The outsourcer routes calls through a Spectrum switch from Rockwell Electronic Commerce (Wood Dale, IL). The center also uses Genesys' (San Francisco, CA) computer telephony and predictive dialing software; it will soon also use software from Genesys to route e-mail messages. The firm places a premium on reliability and it installed the software on multiple servers in case any one server goes down.

At the core of CMC's services and training is its Performance Maximization (PM) model. PM is a comprehensive step-by-step approach that relates performance measurements and maximization to the bottom line. In applying PM, the service bureau performs initial list analysis and tweaks operational requirements. CMC also recruits agents internally according to profiles that reflect requirements specific to each client and each project.

CMC is improving the way it provides feedback to agents. It implemented AutoQuality, e-talk's (Fort Worth, TX) automated digital recording system, along with P&Q Review , e-talk's evaluation software, to monitor agents' calls. CMC will start enabling customers to provide anonymous feedback after phone calls with the help of e-talk's e-talk Survey system before the end of this year.
