MULTIFUNCTIONAL INTERFACE

3 MODULES

For the modular MSR series routers, a wide range of optional MIM/DMIM multifunctional interface modules are available, which provide abundant interfaces, such as synchronous/asynchronous serial interface, Ethernet interface, E1/T1, ISDN BRI/PRI, audio interface, Layer 2 switching interface, and so on.

Among the Layer 2 switching interface cards, neither the XMIM-16FSW nor the XMIM-24FSW supports the PoE function, while the MIM-16FSW and the DMIM-24FSW support the PoE function to provide -48 VDC power to remote PDs (such as IP phone, WLAN AP, network camera) through straight-through network cables as long as installed in a PoE router.

M-4FE Modules

Introduction 1/2/4-port 10/100Base-TX Fast Ethernet interface module (MIM-1FE/MIM-2FE/MIM-4FE) serves to complete communications between routers and LANs.

FE modules support:

■Effective transmission distance of 100 meters with category-5 twisted pair cables;

■Operating speeds of both 100 Mbps and 10 Mbps and autosensing;

■Both full duplex (in common use) and half-duplex operating modes.
