suspended. This is accomplished by sending the interrupt

packets that have been suspended.
7.3.4.6 Comction reset
7.3.4.6.1 SSNWPX. To avoid resets at the SSNDPG
caused by residual DATAIINTERRUPT SNPDUs from the
SSNDPA, the SSNDPA waits until all DATAlINTERRUPT
SNPDUs in transmission and pertaining to that connection
have been transmitted before forwarding RESET or RESET
CONFIRM SNPDUs to the SSNDPG. The SSNDPA need not
correlate the transmission status of each DATAmJTERRUPT
SNPDU with transmission status indications from the data link
layer. However, the SSNDPA waits until all outstanding
DATALNTERRUPT SNPDUs have been acknowledged by
the link layer (successlfait LIDU) before sending a KESET
SNPDU. Since to-aircraft SNPDUs are atways delivered in
proper sequence by the link layer, the SSNDPG may send a
RESET SNPDU without waiting for acknowledgement of
previously sent DATAANTERRu~PT SNPDUs. -
7.3.5 SNPDU FORMATS
7.3.5.1 Fast select facility
7.3.6.1.2 If the throughput class in the CALL
REQUEST packet is less than or equal to the calculated
available value, then the throughput class should be transferred
to the TCN value in the CONNECTION REQUEST SNPDU;
otherwise, the calculated available throughput, rounded down
to the nearest standard value, should be transferred to the TCN
value.

7.3.7.1 GES actions
7.3.7.1.1 If the throughput class negotiation (TCN) value
in the CONNECTION REQUEST SNPDU is -less than or
equal to the calculated available throughput value, the
throughput class in the INCOMING CALL packet should be
set equal to the TCN value; otherwise, the throughput class in
the INCOMING CALL packet should be set equal to the
calculated available throughput, rounded down to the nearest
standard value.
7.3.7.1.2 The selected throughput class in the CALL
CONNECTED packet should be transferred from the TCN
value in the CONNECTION CONFIRM SNPDU.

associated with that GES. This may be done by sending
CLEAR INDICATION packets to each IS0 8208 DCE logical
channel associated with these connections and releasing the
resources for the logical channels in the associated SSNDPA
entity.
7.5.1 .I Connectivity notification
Ways of sending the connectivity notification event messages
through an IS0 8208 DCE entity include the following:
- permanent virtual circuit (PVC);
- CAU REQUEST packet with the fast select facility.
The methd and formats for conveying connectivity event
notifications should be co-ordinated locally between the
subnetwork service provider and the subnetwork service user.
7.5.2 Gm MANAGEMENT INTERFACE
When an AES logssff from a GES, the SSNL should clear
the connections between the SNS user(s) and the logged-off
AES. This may be done by sending CLEAR INDICATION
packets to each IS0 8208 DCE logical channel associated with
these connections and releasing resources for the Iogical
channels in the associated SSNDPG entity.
