非歧视性语言

此产品的文档集力求使用非歧视性语言。在本文档集中，非歧视性语言是指不隐含针对年龄、残障、性别、种族身份、族群身份、性取向、社会经济地位和交叉性的歧视的语言。由于产品软件的用户界面中使用的硬编码语言、基于 RFP 文档使用的语言或引用的第三方产品使用的语言，文档中可能无法确保完全使用非歧视性语言。深入了解思科如何使用包容性语言。

关于此翻译

思科采用人工翻译与机器翻译相结合的方式将此文档翻译成不同语言，希望全球的用户都能通过各自的语言得到支持性的内容。请注意：即使是最好的机器翻译，其准确度也不及专业翻译人员的水平。 Cisco Systems, Inc. 对于翻译的准确性不承担任何责任，并建议您总是参考英文原始文档（已提供链接）。

简介

本文档提供数据呼叫的E1 R2信令的配置示例和故障排除技术。

先决条件

要求

在尝试此配置之前，建议您阅读E1 R2信令理论文档。有关语音应用的E1 R2信令的信息，请参阅文档E1 R2信令配置和故障排除。

使用的组件

此配置使用下面软件和硬件版本开发并且被测试。此配置显示Cisco 3640路由器和Cisco AS5300接入服务器之间的背对背实验设置。

AS5300正在模拟客户端并运行Cisco IOS®软件版本12.2(3)。
3640充当服务器，运行Cisco IOS软件版本12.1(10)。

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

规则

有关文档规则的详细信息，请参阅 Cisco 技术提示规则。

背景信息

E1 R2信令允许思科通用接入服务器与同样使用E1 R2信令的中央局中继通信。R2信令是信道化E1网络通用的国际信令标准。R2信令没有单一标准。ITU-T Q.400-Q.490建议定义了R2，但许多国家/地区以完全不同的方式实施R2。

Cisco Systems通过在其Cisco IOS软件中支持许多R2信令的本地化实施来解决这一挑战。R2自定义本地化意味着R2信令支持范围广泛的国家/地区和地理区域。思科在新的国家/地区持续支持E1 R2信令变体。

注意：仅调制解调器ISDN信道聚合(MICA)和Nextport数字调制解调器模块支持R2功能。Microcom调制解调器或非调制解调器应用不支持R2。

配置

本部分提供有关如何配置本文档所述功能的信息。此配置对以下场景有效：

E1 R2上的调制解调器拨入连接
E1 R2背靠背连接
Cisco路由器之间的E1 R2连接

注意：E1控制器的配置对于数据或语音呼叫是相同的。唯一的区别是：

对于数据呼叫，您需要配置调制解调器以接受呼叫。
对于语音呼叫，您需要配置语音端口以接受呼叫。

注：要查找有关本文档中使用的命令的其他信息，请使用命令查找工具(仅注册客户)。

网络图

本文档使用下图所示的网络设置。

配置

为数据呼叫配置E1 R2涉及两个一般步骤：

配置 E1 R2
配置调制解调器及相关问题

E1 R2配置基于从Telco获取的信息。有关E1 R2特定配置的其他信息，请参阅文档E1 R2信令配置和故障排除。

调制解调器配置类似于任何具有PRI线路的接入服务器的配置。
