Cisco 2-Port FXS/FXS-E/DID and 4-Port FXO Network Interface Module
Brand: Cisco · SKU: NIM-2FXS/4FXO · MPN: NIM-2FXS/4FXO · Category: Components
The Cisco NIM-2FXS/4FXO is a Network Interface Module (NIM) designed for the Cisco 4000 Series Integrated Services Routers (ISRs). It offers 2 FXS/FXS-E/DID ports and 4 FXO ports, totaling 6 analog voice ports. The FXO ports allow connection with Public Switched Telephone Network (PSTN) lines for traditional calls over IP networks, while the FXS ports enable the integration of analog devices like phones or fax machines into an IP-based network environment. The module supports online insertion and removal (OIR). It provides support for voice and fax communications, featuring echo cancellation, DTMF decoding, and Voice Activity Detection (VAD). It supports digital signaling protocols like H.323, MGCP, and SIP, with data compression protocols including G.711, G.726, G.729.A, and G.723. The NIM contains an onboard DSP, eliminating the need for a separate Packet Voice DSP Module (PVDM) on the motherboard for voice features. Required Cisco IOS Release starts from XE3.14.3, XE3.15.1, XE3.16 a
