Cisco NIM-2FXS-4FXOP Router Module 2-Port FXS/FXS-E/DID and 4-Port FXO Network Interface Module
1.Overview:
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. The NIMs support online insertion and removal (OIR), reducing the downtime required for new or replacement modules.
The available modules include 2-port and 4-port foreign exchange station (FXS), direct inward dial (DID), foreign exchange office (FXO), a combination of 2-port FXS and 4-port FXO, 4-port ear and mouth (E/M), and 2-port and 4-port basic rate interface (BRI) (Figure 1). The BRI cards support only voice features. The NIMs have a dedicated digital signal processor (DSP) that will be used for time-division multiplexing (TDM) analog voice services. Table 1 lists the available modules.
Note:These NIMs are not supported with the Cisco 2900 and 3900 Series ISRs.

component into the manufacturing process. There is no change in
functionality from non-P version.

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 generation
●Real-Time Control Protocol (RTCP)
●Acoustic shock protection
●Noise reduction is on the roadmap
●Real-Time Transport Protocol (RTP)
●RFC 4733 Digit Relay
The FXS features include:
●Capable of supporting either FXS or DID functionality
●Configurable long loop ports
●Message waiting indicator (MWI)
●Cable detection
The FXO features include:
●Supports both ground start and loop start modes
●Provides call detail record (CDR) information
●Support for interworking with Cisco Unified Communications Manager (Skinny Client Control Protocol [SCCP]), H.323, Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP) 1.0
●Cable detection
●Overload protection
