Abstract: A TR-8 compatible Remote Terminal (RT) with 96 subscriber line capacity is partially or wholly replaced with one or more D4 channel banks each comprising 24 subscriber line capacity without changing the TR-8 interface module within the servicing telecommunications exchange. The D4 channel bank is connected via a T-1 digital link to any one of the B, C, and D links within the TR-8 interface module. A-B bit pattern data and time slot assignments communicated between the D4 channel bank and the TR-8 interface module are converted to be compatible with each other. Connecting a D4 channel bank to a TR-8 interface module allows small telecommunications service providers to more economically provide line access to sparsely populated customer sites.

Abstract: A toy razor is disclosed which is constructed to be similar in appearance and sound to an electric razor and includes a housing defining an internal cavity within which may be mounted a rotary motor and a power supply such as batteries for energizing the rotary motor. A switch is defined on the housing that connects the motor to the power supply for energization thereof. The toy razor also includes a razor head slideably and reciprocally mounted on the housing. A diaphragm is secured inside the head at a location spaced from the rotary motor such that upon engagement of the shaving head with an object such as the face or hand of a child, the head moves inwardly to vibrate the diaphragm producing a sound similar to the sound of an electric razor.
