Original NIM-2FXS Cisco Network Module 4000 Series 2-Port FXS Interface Module

Product Information

^{The Cisco 4000 Series Integrated Services Routers (ISRs) host the Cisco network interface modules (NIMs), which have evolved from the enhanced high-speed WAN interface card (EHWIC), increasing port density and module capability. Up to three integrated NIM slots on the 4000 Series allow for flexible configurations. The NIMs support online insertion and removal (OIR), reducing the downtime required for new or replacement modules.}

Since the fourth-generation Cisco NIMs have their own DSP to support voice, there is no need to synchronize the clock to the backplane, and the clock-participate command is not supported in the BRI, FXO/FXS, and E/M NIMs. The NIMs support:

• Caller line ID
• G.711, G.729a, and G.726
• G723 and Internet Speech Audio Codec (iSAC); Internet Low Bit Rate Codec (iLBC) is on the roadmap
• Fax detection, pass-through, and relay (T.38)
• Modem detection and pass-through
• Dual-tone multifrequency (DTMF) detection
• Echo cancellation
• Voice activity detection
• Comfort noise generatio
• Real-Time Control Protocol (RTCP)
• Acoustic shock protection
• Noise reduction is on the roadmap
• Real-Time Transport Protocol (RTP)
• RFC 4733 Digit Relay
