A delay correction system is used for a wireless telephone system in which a base station apparatus and at least one subscriber apparatus carry out transmitting and receiving operations via respective communication means, in conformance with a time division multiple access system using the base station apparatus as a synchronization reference. A biased urging member is held at least partially within the outer housing and slidably biased toward a surface of the inner housing. A water reservoir may be disposed in the housing and may have water disposed therein. The problem with this solution is that when used, it ties up the telephone line and requires an additional telephone connection to be located near the cable set-top-box or modem.
