Abstract

<strong><em>Add the following to 1.1 after item q), and change the period after item q) to a semicolon:</em></strong> <br>r) Defines the dedicated token ring (DTR) media access protocols, including finite state machines (FSMs) and state tables (clause 9); <br>s) Defines the frame formats and MAC frames, timers, and error counters for the DTR Station and DTR C-Port (clause 10); <br>t) Defines the DTR Station and C-Port Management (clause 11); <br>u) Provides informative information on the functional description of the DTR concentrator (annex K); <br>v) Provides informative information on the low-level FSMs of the DTR Station and the C-Port in Station Emulation mode using the TXI access protocol (annex L); <br>w) Provides informative information on the low-level FSMs of the C-Port in Port mode using the TXI and TKP access protocol (annex M); <br>x) Provides informative information on the low-level FSMs of the C-Port in Port mode using the TKP access protocol (annex N); <br>y) Provides informative information on channel considerations for 16 Mbit/s DTR (annex O); <br>z) Provides normative information on the BER criteria for lobe media testing (annex P); <br>aa) Provides informative information on the low-level FSMs of the DTR Station using the TKP access protocol (annex a); <br>bb) Provides informative information on the low-level FSMs of the C-Port in Station Emulation mode using the TKP access protocol (annex R); <br>cc) Provides informative information on modifications to clause 4 TKF' access protocol when used to support C-Port operation (annex S); <br>dd) Provides informative information on an optional method for DTR concentrator autodetection (annex T); <br>ee) Defines the functional, electrical, and optical characteristics of a fibre optic interface for connecting a 4 or 16 Mbit/s token ring station to the trunk coupling unit (TCU) of a token ring; <br>ff) Provides informative guidance for connecting fibre trunk cables between trunk coupling units; <br>gg) Describes signaling provisions for bypass of the station from the ring and self-test capabilities. <br><strong><em>Add the following items as subjects for future study after item g):</em></strong> <br>h) Speed negotiation process. <br>i) Low-power protocols for managing stations and C-Ports when the MAC is suspended and the hardware is in a low-power mode.
