Cisco NIM-4FXS

NIM-4FXS is a Cisco 4-Port Network Interface Module – FXS. FXS-E and DID, for ISR4451-X. 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.

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). 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.

GLC-LH-SM

GLC-LH-SM is the 1000BASE-LX/LH SFP for Both Multimode and Single-Mode Fibers. The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable.
