专用综合业务网（PISN）是由一个PINX或多个PINX组成的网络 一个PINX通过内部PINX连接互连。本技术报告涉及国际互联网- 干预网络（IVN）提供的PINX连接（IPC），以及这些连接的方式 由PINX处理，为PINX间的通信提供平台。不同类型的IVN 可用于根据ISO/IEC 11579-1中规定的方案提供IPC。这些 是覆盖场景，因为它们使PISN的服务能够跨网络透明地运行 IVN。 连接的PINx需要协调其IVN的使用，并且需要适当的标准化 允许使用多个供应商的PINX和IVN创建网络。下面 需要考虑以下几点: _一般而言，但取决于IVN的类型，程序和 建立、维护和发布IPC需要PINX。适当的 这些程序和信号协议的标准化是必要的。 _在Q参考点（PINX中的概念点）通道和PISN呼叫控制 信号（QSIG）的定义与IVN的类型无关。然而，在C参考 点（PINX连接到IVN的位置），表示通道和 信号发送取决于IVN的类型，以及PINX如何使用IPC。适当的 有必要在C参考点对这些方面进行标准化。 _一般来说，Q参考点处的通道与其在 C参考点不是静态的，需要程序和PINX之间的信号 为了协调这些关系。这些程序的适当标准化和 信号是必要的。 _需要对适当的机制进行标准化，以便通过 IVN。这些将取决于所用仪表板组合仪表的特性。 本技术报告旨在确定: 1.除了PISN呼叫控制信令（QSIG）之外，为了实现 能够连接PINX； 2.适用于所有（或至少很多）类型的通用技术、程序、协议等 关于IVN。

A Private Integrated Service Network (PISN) is a network comprising either one PINX or more than one PINX interconnected by Inter-PINX connections. This Technical Report is concerned with inter- PINX connections (IPC) that are provided by Intervening Networks (IVN), and the way in which these are handled by PINXs to provide a platform for inter-PINX communication. Different types of IVNs can be used to provide IPCs, in accordance with the scenarios indicated in ISO/IEC 11579-1. These are Overlay Scenarios in that they enable the services of the PISN to operate transparently across an IVN. Connected PINXs need to co-ordinate their use of IVNs, and appropriate standardisation is needed to allow networks to be created employing PINXs and IVNs from multiple vendors. The following points need to be considered: _ In general but depending on the type of IVN, procedures and signalling protocols between the PINXs are needed for the establishment, maintenance and release of IPCs. Appropriate standardisation of these procedures and signalling protocols is necessary. _ At the Q reference point (a conceptual point within a PINX) channels and PISN call control signalling (QSIG) are defined independently of the type of IVN. However, at the C reference point (where the PINX is connected to the IVN), the representation of the channels and of signalling is dependent on the type of IVN, and on how the PINXs use the IPCs. Appropriate standardisation of these aspects at the C reference point is necessary. _ In general the relationship between a channel at the Q reference point and its representation at the C reference point is not static, and procedures and signalling between the PINXs are needed for the co-ordination of these relationships. Appropriate standardisation of these procedures and signalling is necessary. _ Appropriate mechanisms need to be standardised for conveying inter-PINX signalling through the IVN. These will depend on the characteristics of the IPC used. The aim of this Technical Report is to identify: 1. In addition to PISN call control signalling (QSIG), what needs to be standardised, in order to be able to inter-connect PINXs; 2. General techniques, procedures, protocols etc., that apply to of all (or at least very many) types of IVNs.
