5 Although predominately used in K-12 schools, the system often finds applications in retirement homes, parking garages, large office buildings and large manufacturing facilities. This Manual , however, is written with academic applications in mind. The system provides communication between telephones (usually in the school office area) to speakers throughout the school. In this Manual , these phones will be referred to as office telephones.

6 The Class ConnectionTM can interface with single line telephones or with loop start trunk or FXO ports on the school s telephone system. Calls may be either from the office telephones to the speakers (via dial up), or from a speaker location to the office telephone (via call button). This document will primarily focus on system Installation . Specifications, features and benefits, and support product information will not be included here.

7 Our intent is to make this Installation Manual as simple as possible. Class ConnectionTM is comprised of as few as 2 and as many as 16 circuit cards dependant upon system size. Every Class ConnectionTM System must have a VECPU card and at least one VETCM, XPETCM24, XPETCM12, VESTX or V-URI card. A description of each of these cards is provided on the following pages. Company confidential 5 2008 Valcom, Inc. 5614 Hollins Road Roanoke, VA 24019 Telephone: : circuit cards mount in a card cage and typically connect to each other via a backplane cable.

8 Class Connection IPTM features Ethernet distributed system hardware to virtually eliminate the need for multi pair feeder cables. Connections from these cards to other system components (speakers, call buttons, etc) are made on external 66M150 25 pair split Connection blocks. These blocks connect to the cards by 25 pair telephone cable terminated with a female 25 pair amphenol connector. The system is powered by external 24 Volt DC power supplies (2 amps per card).

9 In this Manual , the Connection blocks for the individual cards are shown in the card description sections of this document. Common sense guidelines such as wearing a properly configured grounding strap when handling cards, verifying all connections before applying power and removing AC power before servicing the system should always be observed. General Installation guidelines, wiring, power supply requirements /placement, are described in following sections.
