Introduction The DCT4960 Cordless Telephone is a frequency hopped spread spectrum transmitter to be compliance with US (FCC Part 15.247) and Canadian (RSS-210) regulations for license free use in the 2400-2483.5MHz ISM band. The DCT4960 Cordless Telephone operates in the ISM (Industrial Scientific and Medical) band (2400 ~ 2483.5 MHz). The 20dB bandwidth of the hopping channels used in DCT4960 is less than 1MHz. And the number of hopping channels used in DCT4960 is 75. It complies with FCC part 15.247(a)(1)(ii). The DCT4960 is a frequency hopper, it uses the full available frequencies in the ISM band for operation and can make it difficult for other 2400MHz devices to operate correctly. The 20dB bandwidth of the hopping channels is about 670 KHz and any two consecutive channels are separated by a bandwidth greater than 670 KHz. It complies with FCC part 15.247(a)(1). The maximum power used in DCT4960 base station and handset are 11.0 mW and 7.08 mW respectively. It complies with FCC part 15.247(b)(2). Each DCT4960 base station supports up to four handsets and uses Time Division Duplex to distinguish the four handsets. Tech Description 2 November 3, 2001 II. Specifications Operating Frequency Range: 2400 ~ 2483.5 MHz Number of Used Channels: 75 RF Output Power: 7.08mW (Handset) / 11.0mW (Base) Range: 90m/600m (In Door/Out Door) Type of Spread Spectrum: Frequency Hopped Spread Spectrum Bandwidth of Channel: ≤ 1MHz (It is 670 KHz.) Channel Separation: ≥ 670KHz (It is 863 KHz.) Duplexing: Time Division Duplex Power Supply: 3.6 VDC (Handset) / 120VAC Adapter (Base) Tech Description 3 November 3, 2001 III. Technical Description 1. General The DCT4960 Cordless Telephone is a frequency hopped spread spectrum transmitter to be compliance with US (FCC Part 15.247) and Canadian (RSS-210) regulations for license free use in the 2400-2483.5MHz ISM band. The DCT4960 is a multiple-handset, single-base cordless telephone system, which provides a full-integrated mobility solution for your business. The DCT4960 handset allows you to freely move around your working space while on a call, and still maintain access to all your telephone system features. The DCT4960 telephone uses advanced digital frequency hopping spread spectrum (FHSS) technology to provide a quality audio path over a 2400MHz radio link. Establishing a call over a radio link is comparable to a wire line communication. The frequency band is divided into 75 channels in DCT4960. And 75 channels are used for each DCT4960 base and handset. Each message from DCT4960 base to handset is four frames in length. That is the message from DCT4960 base to handset hops on four different channels. The DCT4960 handset receiver gets the message from four different hopping channels. The message from…
