Year: 1998

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