Provisioning the T7406

This chapter provides specification and provisioning information for the T7406 cordless system.

The T7406 is a Frequency Hopping Spread Spectrum (FHSS) cordless telephone. The benefits of this technology are: improved range, robustness and, less susceptibility to interference, fading and multipath.

The use of a common wall-mounted base station for multiple handsets allows you to position the base antennas for maximum performance and coverage. The indoor range of the T7406 is 95 meters (300 feet) in a typical office environment. This range may vary with differing environments.

Operational Bandwidths

The T7406 cordless telephone operates in the ISM (Industrial, Scientific, and Medical) 902-928 MHz band. The T7406 divides the ISM band into two sets of operating frequencies to allow the coexistence of other ISM devices. Examples of these products are SKU scanners and remote controls for products such as garage door openers and home theatre systems. Note that, since the T7406 is a frequency hopper, it uses at least half of the available frequencies in the ISM band for operation and can make it difficult for other 900 MHz devices to operate correctly. The following table identifies the frequencies used for the upper and lower bands of operation:

Lower: 902 - 915 MHz

Upper: 915.1 - 928 MHz

These bands are selectable for each base station through dip switches located on the back of the T7406 base station. Each base station supports up to three handsets. Selection of the correct band for operation may minimize interference between devices.

Operational Parameters

For example, with a configuration of six handsets, two base stations are required (three handsets per base station). One base station will be set to the upper band, and the other base station will be set to the lower band.
