First Claim
Patent Images
1. A method for controlling a plurality of service units in a telecommunication system with a multi-carrier transmission scheme, comprising the steps of:
- assigning an identifier to each service unit;
assigning each service unit to a subband of a transmission channel of a narrow band transmission scheme, wherein each subband includes a control channel for receiving and transmitting control signals;
broadcasting control signals for the service units over the control channels in a number of subbands; and
identifying the service unit to use the control signal with the identifier.

7. The method of claim 1, wherein broadcasting control signals comprises broadcasting the same control signals on the control channel in each subband.
-
8. The method of claim 7, wherein broadcasting control signals comprises broadcasting the same control signals simultaneously on the control channel in each subband.
-
9. The method of claim 1, wherein assigning an identifier to a service unit comprises assigning an identifier during initialization of the service unit.

3. A service unit for use with a communication system that transmits signals with a multi-carrier transmission scheme wherein a transmission channel is divided into a number of subbands each subband including a number of payload channels and a control channel, the service unit comprising:
-
a modem that is tunable to receive telephony and control signals on a subband of a transmission channel;
a controller circuit coupled to the modem to receive control signals over the control channel and to determine which control signals to use to control the operation of the modem; and
interface circuits coupled to the controller for providing signals to a channel unit. - View Dependent Claims (14, 15, 16, 17)
