according to 4.9.3.3.2 and then shall log-on to the
selected GES in accordance with 4.9.3.3.3.
b) If within tAll seconds the AES management receives a
4.9.3.3 AES LOG-STATUS MANAGEMENT log-on confirm LDU, and the channel control LIDUS
(P/ R and T channel control LIDUs) indicated in the log-
4.9.3.3.1 Before an AES begins providing user communi- on confirm LDU, the AES management shall command
cation services, the &S management shall successfully the selection of an Rd channel frequency and then shall
complete the log-on procedure, given in 4.9.3.3.4, with a transmit a log-on acknowledgement LIDU indicating the
selected GES. Prior to initiating the log-ou procedure, the AES correct receipt of all expected LlDUs to the GES. If,
management shall select a suitable satellite, beam and GES after tA12 seconds from sending a log-on accombination

receive a log-on acknowledgement LDU from thc GES
on the assigned Pd channel, il shall command the
selection of an Rd channel frequency and lhcn shall
retransmit the log-on acknowledgement LIDU. The AES
management shall command the selection of an Rd
channel frequency and then shall retransmit the same
LJDU every tA12 seconds until a log-on acknowledgement
LIDU is received from the GES, except
that the total number of transmissions of the log-on
acknowledgemenl LIDU shall not exceed lour. If, after
tA12 seconds from the fourth transmissiou, a log-on
acknowledgement LIDU is not yet received from the
GES, the AES management shall abort the log-on
procedure to the current selected GES, select a GES
accordng to 4.9.3.3.2 and then shall log-on to the
selected GES in accordance with 4.9.3.3.3; otherwise,
when a log-on acknowledgement LDU is received, the
AES shall be considertd logged on. The AES
management shall then relay this information on the
various interfaces, where applicable, and update its logon
confirm table.
c) If some, but not all, of the expected LIDUs are received
within tAll seconds, the AES management shall
transmit a log-on acknowledgement LIDU to the GES
indicating the missing LIDUs. If, after tAll seconds
from the time the AES log-on acknowledgemenl LIDU
was transmitted, the AES management still has not
received all expected LIDUs, it shall command the
selection of an &,, channel, frequency and then
retransmit another log-on acknowledgement LIDU
indicating all missing LDUs to the same GES. The
M S management shall command the selection of an
R, channel frequency and then shall repeat the
transmission of a log-on acknowledgement LIDU,
indicating all missing LZDUs, every tAll seconds until
all expected LIDUs are received, except that the total
number of transmitted log-on request LIDUs (in a)
above) and log-on acknowledgement LIDUs shall not
exceed five. If, after tAll seconds from the fifth
transmission, all expected LIDUs have no1 been
received, the AES management shall, abort the log-on
procedllre to the current selected GES, select a GES
according to 4.9.3.3.2 and Ulen shall log-on to the
selected GES in accordance with 4.9.3.3.3. If, and when,
within the required time lhe AES management receives
all the expected LLDUs, it shall transmit a log-on
acknowledgement LDU indicating no errors to the GES
and shall then proceed as given in b).
d) If a log-on reject LIDU is received, the AES
management shall respond according to the rejection
reason (Appendix 3 to Chapter 4, item 44) indicated in
the LIDU.
e) If a log-off request LIDU is received from the GES, the
AES inanagement shall consider the AES logged off and
immediately inhibit its transmissions on the R and T
channels to the GES. The GES shall be considered as
"temporarily unavailable" (see Appendix 3 to Chapter 4,
Item 44).
f) If a selective release broadcast LIDU is received from
the GES, the AES shall immediately inhibit any
transmission on the frequency specified in the LIDU.
4.9.3.3.3.2.1 If during the log-on procedure the AES
management receives a P channel lossldegradation indication
(defined in Appendix 1 to Chapter 4), it shall abort the log-on
procedure to the current selected GES, select a GES according
to 4.9.3.3.2 and log on to the selected GES in accordance with
4.9.3.3.3.
4.9.3.3.4 PROCEDURES AFTER LOG-ON
4.9.3.3.4.1 The AES management shall attempt to log-off
before terminating communication with the log-on GES.
Note.- Loss or degradation of the P channel precludes any
log-off attempt (4.9.3.3.4.4 refers).
