Description
図1は例示的なHDR通信システムの図である。ここではアクセスターミナル(AT)102として言及されるHDR加入者局は移動的または静的であってもよく、ここではモデムプールトランシーバ(MPT)108として言及される1つ以上のHDR基地局と通信してもよい。アクセスターミナル102は1つ以上のモデムプールトランシーバ108を通して、ここではモデムプール制御装置(MPC)110として言及されるHDR基地局制御装置との間でデータパケットを送受信する。モデムプールトランシーバとモデムプール制御装置はアクセスネットワークと呼ばれるネットワークの一部である。アクセスネットワークは複数のアクセスターミナル間でデータパケットを転送する。アクセスネットワークはアクセスネットワークの外部の、コーポレートイントラネットまたはインターネットのような付加的なネットワークにさらに接続されてもよく、各アクセスターミナルとこのような外部ネットワークとの間でデータパケットを転送してもよい。1つ以上のモデムプールトランシーバとのアクティブトラフィックチャネル接続を確立したアクセスターミナルはアクティブアクセスターミナルと呼ばれ、トラフィック状態にあると言われる。1つ以上のモデムプールトランシーバとのアクティブトラフィックチャネル接続を確立するプロセスにあるアクセスターミナルは接続セットアップ状態にあると言われる。アクセスターミナルは、例えば光ファイバまたは同軸ケーブルを使用して、ワイヤレスチャネルを通してまたはワイヤードチャネルを通して通信する何らかのデータデバイスであってもよい。アクセスターミナルは、さらに、これらには限定されないが、PCカード、コンパクトフラッシュ(登録商標)、外部または内部モデム、あるいはワイヤレスまたはワイヤライン電話を含む多数のタイプのデバイスの任意のものとしてもよい。アクセスターミナル102が信号をモデムプールトランシーバ108に送信する通信リンクはリバースリンクと呼ばれる。モデムプールトランシーバ108が信号をアクセスターミナル102に送信する通信リンクはフォワードリンク106と呼ばれる。
