Communication system with a request by a single node made over one of two separate timeslots
First Claim
1. A communication controller in a data network, the data network including a plurality of nodes, the communication controller comprising:
- a processor;
a memory; and
at least one interface for communicating with the plurality of nodes and interacting with the processor as controlled by code stored in the memory, wherein the interface is configured to;
receive a request signal provided from a first node in the plurality of nodes and a random access request signal from a second node in the plurality of nodes, the request signal selected by the first node from one of a first slot and a second slot when the first node has upstream information to transmit,transmit downstream authorization information from the communication controller subsequent to the communication controller receiving said request signal from the first node, said downstream authorization information comprising information which allows the first node to transmit the upstream information from the first node to the communication controller,wherein the first slot in which the first node may transmit said request signal is a slot where the plurality of nodes including the second node can transmit random access requests, andwherein the second slot in which the first node may transmit said request signal is a slot which is exclusively assigned to the first node.

Abstract
A communication system is provided for communication between network nodes and a communication controller. In the network, a request signal is transmitted from a node to the communication controller in one of two separate timeslots to enable transmission of a signal from the individual node. A first one of the reservation timeslots provides for random access requests that can be made by multiple ones of the nodes. A second one of the timeslots is assigned exclusively to the one node. The first random access request timeslot can be used to carry requests for assignment of an exclusive node, while the second exclusively assigned reservation request timeslot can be provided to carry requests to transmit packets containing alphanumeric data.
