Generic Modules

The MSR 20 series is available with generic modules such as SIC interface card and ESM. For detailed
information about interface cards, refer to MSR Series Routers Interface Card and Interface Module
Manual.

SIC and DSIC Interface Cards

MSR series routers adopt modular design and support a wide range of optional SIC/DSIC interface
cards, providing various interfaces, such as synchronous/asynchronous serial interface, Ethernet
interface, E1/T1, ISDN BRI/PRI, ADSL, audio interface, and Layer 2 switching interface, and so on.
