产品概述

Cisco ^®高密度模拟语音和传真服务模块使企业、托管服务提供商和服务提供商能够将公共交换电话网络 (PSTN) 和现有电话设备直接连接到 Cisco 4000 系列集成多业务路由器 (ISR)。这些固定端口（FXS 和 FXO）模块提供双音多频 (DTMF) 检测、语音压缩和解压缩、呼叫进程音生成、语音活动检测 (VAD)、回声消除和自适应抖动缓冲。

产品详情

FXO 端口用于连接到 PBX 或关键系统，或提供到 PSTN 的外部连接。它支持电池反接检测和来电显示。FXO 端口还用于连接模拟集中自动消息记帐 (CAMA) 中继，以提供专用的 E-911 服务（仅限北美）。

FXS 端口用于将模拟电话、调制解调器、传真机和免提电话连接到企业 IP 语音系统，因此您可以将它们用作 Cisco 或第三方 IP 呼叫控制系统的扩展。将这些设备与基于 IP 的电话系统紧密集成有利于提高可管理性、可扩展性和成本效益。直接拨入 (DID) 端口用于提供来自中心局的外部 DID 连接。它只为来自 PSTN 的来电提供服务。DID 模式不支持来电显示。

特点和好处

新一代思科高密度模拟语音和传真服务模块改进了之前的高密度模拟和数字扩展模块 (EVM)。这些改进在下面突出显示：

● 板载数字信号处理器（DSP）： FXO 和FXS 业务模块包含一个板载DSP，不需要路由器在主板上配备专用的分组语音DSP 模块（PVDM）。语音模块上的 DSP 是语音功能所必需的。它还为苛刻的网络条件提供了长达 128 毫秒的回波尾长度的回波消除。

● 支持在线插拔（OIR）： FXS 和FXO 业务模块支持在线插拔（OIR），减少了新模块或更换模块所需的停机时间。服务模块可以插入到支持的 Cisco 4000 系列 ISR 上的 SM-X 插槽中，而无需关闭路由器电源。

● FXS-E（扩展环路）支持：新模块上的FXS端口支持FXS-E，具体如下：

◦ 更高的回路电流 (35 mA) 以适应特殊电话

◦ 使用 26 AWG 电线的环路的环路长度更长，最长可达 11,000 英尺（3400 米）

◦ 更高的振铃电压（65 Vrms，无负载）

请参阅表 2 了解每个模块中的 FXS-E 端口数量。SM-X-72FXS 模块支持两种 FXS-E 模式：

模式 1（默认）：前 16 个端口启用 FXS-E，其余 56 个端口作为常规 FXS。

模式 2：前 56 个端口启用 FXS-E，其余 16 个端口禁用。

注意：在模式之间切换需要重新加载 ISR 机箱。

● FXO 故障切换旁路端口：故障切换旁路端口，也称为故障切换中继旁路，提供了一种在断电期间使用指定模拟电话端口通过 PSTN 拨打电话的方法。表 2 总结了每个服务模块中支持的 FXO 故障转移旁路功能。

除了上面列出的功能之外，服务模块还支持：

● 来电号码

● G.711、G.729a、G.726

● G722、iLBC、GSMAMR-NB 和互联网语音音频编解码器 (iSAC)

● 传真检测、直通和中继 (T.38)

● 调制解调器直通

● DTMF 检测

● 回声消除

● 语音活动检测

● 舒适噪音产生

● 实时控制协议（RTCP）

● 声震保护

● 实时传输协议 (RTP)

● RFC 4733 数字中继

● 降噪在路线图上

FXS 功能包括：

● 支持 FXS 或 DID 功能

● 消息等待指示器 (MWI)

● 线缆检测：GR909线路测试

FXO 功能包括：

● 支持接地启动和环路启动模式

● 呼叫详细记录 (CDR) 信息

● 支持与 Cisco Unified Communications Manager（瘦客户端控制协议 [SCCP]）、H.323、会话发起协议 (SIP) 和媒体网关控制协议 (MGCP) 1.0 互通

● 线缆检测

● 过载保护
