新闻要点：

远程协议分析仪，或RPA，功能是基于GUI协议分析仪的扩展。对于基于HDLC的协议如ISDN,SS7,GR303等，装有T1或E1协议分析仪的软硬件都可以远程控制。

摘要：

• RPA进行在复杂环境下进行详细的远程无扰测试，并可以无人照管运行。

• 控制端需要安装T1/E1硬件，服务器软件及HDLC采集软件.

• HDLC帧信息可以通过TCP/IP传输，并由GUI协议客户端接收进行实时地储存、分析、筛选、显示和数据处理。

• 传输帧信息的局域网或广域网带宽要满足协议需要.

GL Communications offers remote protocol analysis

Remote protocol analyzer, or RPA, functionality is an extension of the feature-rich capability available with GL Communications’ GUI-based protocol analyzers. HDLC-based protocols, such as ISDN, SS7, GR303, and others, can be monitored remotely via a set of hardware and software features available with the company’s T1 and E1 protocol analyzers.

The RPA function permits unattended operation 24/7, remote accessibility for difficult connection situations, remote non-intrusive operation, and remote detailed diagnostic capability.

For HDLC-based protocols, HDLC frames can be transported via TCP/IP and captured remotely with a GUI protocol analyzer client. At the client location, the full capability of a real-time protocol analyzer is available for storing, analyzing, filtering, displaying, and processing the protocol information.

At the monitoring site, the T1/E1 hardware, server software, and HDLC capture software are all that is required irrespective of the protocol being monitored. At the remote site, the appropriate GUI-based protocol analyzer receives HDLC frames and performs the protocol analysis function as if the remote link did not exist. The bandwidth of the LAN or WAN link transporting the HDLC frames should be adequate for the protocol being monitored.
