ISDN 用户部分消息和代码
表 21 到 50, 是ISDN 用户部分消息代码的详细说明. 列表说明每个参数的相关代码:
–
参数类型的种类：
F = 必选固定长度参数；该参数必定出现，八位位组长度固定，由消息类型确定；
参数的位置、长度、顺序统一由消息类型确定，故在该消息中不包括该参数的
名字和长度表示语。
V = 必选可变长度参数；该参数必定出现，八位位组长度不固定，其长度范围由
消息类型确定；有一指针用来表明每一参数的开始，指针按单个八位位组编
码，每个参数名字、指针的发送顺序隐含在消息类型中，参数的数目和指针
的数目统一由消息类型确定，每个参数包括参数长度表示语和参数。
O = 任选参数；该参数不一定出现，八位位组长度不固定，其长度范围由消息类
型确定；这些参数在指定的消息类型中可能出现也可能不出现，参数有固定
长度和可变长度两种，任选参数可按任何顺序发送，每一任选参数应包括参
数名（一个八位位组）、长度表示语（一个八位位组）和参数内容，如果有
任选参数，任选参数发送完后，发送全0的八位位组表示任选参数结束。
指针：指示各个必选可变部分的开始或任选部分的开始，若该部分不存在，则指针不
存在，若消息类型表明可能有任选部分，而在该消息中又不包含任选部分，则
指示任选部分的指针为全0，指针的数值为：于该指针有关的参数的指针本身
（包括）和该参数的第一个八位位组（不包括）之间的八位位组数目，所有
指针在必备可变部分的开始连续发送。
长度表示语：表明参数内容字段中八位位组的数目。

The information element is coded as described in 4.5/Q.931. Multiple Q.931 information elements can be included within the access transport parameter. The information elements applicable to a particular usage of the access transport parameter are dependent on, and will be determined by, the relevant procedures. The maximum length of the access transport parameter should only be limited by the message length as the content of the ATP will probably evolve in the future.

组元Components
This item provides the format and encoding of Component(s). The description is divided in two sub-items.
Sub-item i) uses the description method of other Q.700-Series Recommendations. The content is based on the encoding rules provided in Recommendation燲.209 and is consistent with that Recommendation.
Sub-item ii) uses Recommendation X.209 formal description language (ASN.1).
The general component structure and encoding rules are described in Annex燘/Q.763.
i)
Specification of components in table form
1)
Component type
The Components are based on the Remote Operations Service Element (ROSE) of Recommendation X.229. The four component types defined for the Remote Operation parameter are as follows:
–
Invoke;
–
Return Result;
–
Return Error;
–
Reject.
2)
Component type tag
Each Component is a sequence of information elements. The Component types have the structure indicated in Tables 6 to 9.
The information element for the various components shown in Tables 6 to 9 are all mandatory except the Linked ID and the parameters.
The Parameter Tag shall be any valid ASN.1 tag, depending on the type of the parameter supplied. It can indicate either a primitive or a constructor element and refer to any of the defined tag classes.
When the parameter element is a collection of several information elements, the associated data type shall be derived from the Sequence, SequenceOf, Set or SetOf types.
Subclause 3.48 c) i) 6) and Table 14 define the Sequence and Set tags.

Length of each Component or of their Information Elements
The length of the contents is coded to indicate the number of octets in the contents. The length does not include the Tag nor the Length of the Contents octet.
The length of the contents uses the short, long or indefinite form. If the length is less than 128 octets, the short form is used. In the short form, bit H is coded 0, and the length is encoded as a binary number using bits A to G. The format of this length field is shown in Figure 47.

Figure 47/Q.763 – Format of the length subfield (short form)
If the length is greater than 127 octets, then the long form of the length of the contents is used. The long form length is from 2 to 127 octets long. Bit H of the first octet is coded 1, and bits A to G of the first octet encode a number, one less, than the size of the length in octets as an unsigned binary number whose MSB and LSB are bits G and A respectively. The length itself is encoded as an unsigned binary number whose MSB and LSB are bit H of the second octet and bit燗 of the last octet, respectively. This binary number should be encoded in the fewest possible octets, with no leading octets having the value 0.
The format of this length field is shown in Figure 48.

Component ID Tag

a)
This tag differs from the Invoke ID, which is coded as a Universal INTEGER, in order to distinguish it from the following tag (Operation Code) which is also coded as a Universal INTEGER.
The length of a Component ID is 1 octet.
An Invoke Component has one or two Component IDs: an Invoke ID and if it is desired to associate the Invoke with a previous Invoke, then the second or Linked ID is provided in addition to the Invoke ID.
Return Result and Return Error Components have one Component ID, called an Invoke ID which is the reflection of the Invoke ID of the Invoke Component to which they are responding.
The Reject Component uses as its Invoke ID, the Invoke ID in the component being rejected. If this ID is unavailable (e.g. due to mutilation of the message undetected by lower layers), then the Invoke ID Tag is replaced with a universal Null Tag (which always has length = 0) as shown in Table 12).

Operation Code Tag
Each operation is assigned a value to identify it. Operations can be classified as local or global operations.
A local operation code follows an Operation Code Tag and Operation Code Length. The Operation Code Tag is coded as shown in Table 13.

Parameter Tag
The Parameter Tag shall be any valid ASN.1 Tag, depending on the type of the parameter supplied. It can indicate either a primitive or a constructor element and refer to any of the defined tag classes.
When the parameter element is a collection of several information elements, the associated data types shall be derived from the Sequence, SequenceOf, Set or SetOf types.

Each error is assigned a value to identify it. Errors can be classified as local or global errors. A local error code follows the Error Code Tag and Error Code Length. The Error Code Tag is coded as shown in Table 15.

Problem Code
The Problem Code consists of one of the four elements爾燝eneral Problem, Invoke Problem, Return Result Problem or Return Error Problem. The tags for these elements are coded as shown in Table 16. Their values are shown in Tables 17 to 20.
