MULTIFUNCTIONAL INTERFACE
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.
MIM-1FE/MIM-2FE/MI
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.
