THE SCENARIO
An imaginary company called Industry Inc. has the following requirements for a new business telephone system that it intends to roll out in two phases. The first phase starts immediately. The second phase has a completion target of one year from now (mid-2003).
Industry Inc.s data network is a separate but related issue in the build-out of the VOIP network. Industry Inc. is not wedded to the idea of having the same vendor supply both the data and voice network equipment. Do not include data networking equipment in the proposal unless it is required to support the VoIP implementation.
-
Phase 1 1,500 Ethernet-connected handsets
For this part of the response, you may only reference shipping products and software.
-
Phase 2 (one year later) 10,000 Ethernet-connected handsets
You may reference products that are not currently available BUT ARE EXPECTED TO BE AVAILABLE in the next year. You must provide approximate shipping dates for each product.
DETAILS
We understand that each customer is different and that these differences can have a profound impact on equipment, services and cost of an implementation. Therefore, please provide as much context to your responses as possible. Put another way, it is better for you to over-explain your response, giving the benefits and drawbacks of various choices an IT manager could make.
1. Architecture
Describe the overall architecture of the system. Provide diagrams that illustrate all of the major network components, their roles and interactions with each other. Where applicable, indicate the OS that the server software runs on. Show all PBX servers, gateways and handsets, as well as any other relevant equipment. Use diagrams to show how your products connect to the PSTN (Public Switched Telephone Network).
- Provide a separate diagram for Phase 1 and Phase 2.
- You should refer to these diagrams in later sections.
2. Telephone handsets
Telephone handsets should be line-powered. Locally powered handsets will be considered, but are definitely the second and less preferred choice. Provide the part number and price (list price only for volumes describe in each phase of the project.)

- 50 Private Residences: 1 handset, 1 inbound/outbound lines, DID, voice mail.
- 100 Salespeople who use soft phones via a hotel high-speed Internet connection.
- What power standards (or developing standards) or protocols do you adhere to? For example, 802.3af.
- Additional Features. What features, other than those detailed above, distinguish your handsets?
- Suppliers. List third-party handsets that are compatible with your system. Be specific; more is better.
3. Call Processor Functionality
- How many systems using which cards are necessary to support IP 1,500 handsets?
- Describe how the system can be scaled up to 10,000 handsets.
- Describe phone how phone management is distributed across the respective servers. Specifically:
- Under what circumstances do you recommend concentrating all voice mail at a central location?
- Under what circumstances do you recommend distributing voice mail to branch offices/remote factories?
- Given that Industry Inc. wishes to consolidate as much telephone specific administration to the headquarters office, describe what services MUST be administered locally.
- Do you provide Automatic Route Selection/Least Cost Routing?
- Detail the pre- and post-sales traffic analysis tools including traffic reports and services that assist IT staff in designing:
- Fail over routing plans
