b) bit 2, called NSAP address present;
c) bit 3, calling NSAP address present; and
d) bit 6, fast select with restriction on response.
4.7.3.10.2.2.2 Bits 1, 2 and 3 shall be set to 1 if the
corresponding fields are present in the connection request
SNPDU; otherwise, they shall be set to 0. Bit 6 shall be set to
1 if fast select with restriction on response applies; otherwise,
it shall be set to 0.
4.7.3.1 0.2.3 DTE address length field
Octet 3 shall consist of the calling- and called-DTE address
length fields. Bits 8 to 5 shall specify the length of the calling-
DTE address in semi-octets. Bits 4 to 1 shall specify the
length of the called-DTE address in semi-octets. Each addresslength
field shall be binary coded, where bit 5 or 1 shall be
the low-order bit of the indicator.
4.7.3.10.2.4 Calling- and called-DTE fields
4.7.3.10.2.4.1 When indicated by the DTE addresses
length field, the octets following the DTE addresses length
field shall contain the called-DTE address followed by the
calling-DTE address.
4.7.3.10.2.4.2 Each digit of an address shall be coded in
a semi-octet in binary-coded decimal, where bit 5 or bit 1 shall
be the low-order bit of the digit.
4.7,3.10.2.4.3 Starting from the high-order digit, a DTE
address shall be coded in consecutive octets, with two digits
per octet. In each octet, the higher-order digt shall be coded
in bits 8 to 5. When the total number of digits in the calledplus
calling-DTE fields is odd, the combined fields shall be
rounded up to an integral number of octets by inserting zeros
in bits 4 to 1 of the last octet of the combined fields.
4.7.3.10.2.5 Culled- and calling-NSAP
address fields
When indicated by the called- and calling-NSAP address
present indicator bits, the octets following the calling- and
called-DTE fields shall contain the called-NSAP address field,
then the calling-NSAP address field.
4.7.3.10.2.6 Facility field length field
When indicated by the facilities field present indicator bit, the
next octet shall contain the length of the facilities field in
octets. The facility field length field shall be binary-coded,
where bit 1 shall be the low-order bit of the field.
4.7.3.10.2.7 Facilities field
When indicated by the facilities field present indicator bit, the
octets following the facility field length field shall contain the
codes and parameters for the facilities.
4.7.3.10.2.8 Call user data field
The next octets shall be used to carry the call user data, if any.
If fast select facility is not used, not more than 16 octets of
data shall be present. If fast select facility is used, not more
than 128 octets of data shall be present.
4.7.3.10;3 CONNECTION CONFIRM s m u
4.7.3.10.3.1 The format of the connection ' confirm
SNPDU shall be as specified in Figure 4-15.
4.7.3.10.3.2 SNPDU type identifier Jield
4.7.3.10.3.2.1 Bits 1 and 2 shall be the following
indicator bits:
a) bit 1: facilities field present; and
b) bit 2: NSAP address present.
4.7.3.10.3.2.2 These bits shall be set to 1 if the corresponding
fields are present; otherwise, they shall be set to 0.
4.7.3.10.3.3 Called-NSAP address $eld
When indicated by the NSAP address present indicator bit, the
octets following the logcal channel number field shall consist
of the called-NSAP address.
4.7.3.10.3.4 Facility length field
When indicated by the facilities field present indicator bit, the
next octet shall contain the length of the facilities- field in
octets. The facility length indicator shall be binary-coded,
where bit 1 shall be the low-order bit of the field.
4.7.3.10.3.5 Facilities $field
When indicated by the facilities field present indicator bit, the
octets following the facilities field shall contain the codes and
parameters for the facilities.
4.7.3.10.3.6 Called user data field
The next octets shall be used to carry the called user data, if
any. If fast select facility is used, not more than 128 octets of
data shall be present.
Part Z Annex 10 - Aeronautical Telecommunications
4.7.3.10.4.1 The connection released SNPDU format
shall be as defined in Figure 4-16.
The M-bit shall be set to I if the SNPDU is not the last in
an M-bit sequence of data SNPDUs; otherwise, it shall be set
to 0.
4.7.3.10.4.2 SNPDU type idenrij'ierjield
4.7.3.10.6.3 SNPDU number field
4.7.3.10.4.2.1 Bit 2 shall be the N Sadd~ress present
indicator bit.
4.7.3.10.4.2.2 This bit shall be set to 1 if the called-
NSAP address field is present; otherwise, it shall be set to 0.
4.7.3.10.4.3 Called-NSAP address field
This field shall have the same coding as 4.7.3.10.3.3.
