1.  Introduction

   The dynamic Link Exchange Protocol (DLEP) is defined in [RFC8175].
   It provides the exchange of link-related control information between
   DLEP peers.  DLEP peers are comprised of a modem and a router.  DLEP
   defines a base set of mechanisms as well as support for possible
   extensions.  This document defines one such extension.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

2.  Extension Usage and Identification

   The use of the Channel Utilization Extension SHOULD be configurable.
   To indicate that the Channel Utilization Extension is to be used, an
   implementation MUST include the Radio Channel Active and Radio
   Channel Busy Value in the Extensions Supported Data Item.  The
   Extensions Supported Data Item is sent and processed according to
   [RFC8175].

   The Radio Band Extension Type Value is TBD; see Section TBD.

3.  Radio Channel Active Data Item

   Radio Channel Active Item is mandatory and contains information how
   long the radio channel has been active.  This value is usually
   interface specific.

   The value in this item must be larger than the values in the other
   three Data Items this extensions define together.

   The format of the Radio Channel Active Data Item is:

   0                   1                   2                   3
