Generic Modules

The MSR 20 is available with generic modules such as SIC interface card and ESM. For detailed
information about interface cards, refer to MSR Series Routers Interface Module Manual.
For the types of interface modules that each model of the MSR 20 routers can accommodate, refer to
Appendix A Interface Card and Interface Module Purchase Guide in the MSR Series Routers 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.
NOTE:
• For an MSR 20-40 router, 4FSW/1FEA/1GEC/1ADSL/1ADSL-I can only be installed in Slot 2 or Slot
4.
Currently, MSR 20 routers do not support PoE and regard SIC-4FSW-POE and DSIC-9FSW-POE (if
•
used) as only ordinary Layer 2 switching modules.

ESM Module

High-performance network data encryption ESM module (ESM-ANDE)
•
Standard network data encryption ESM module (ESM-SNDE)
•
ESM module supports IPSec and by using hardware encryption expedites IP packet encryption. The use
of hardware encryption/decryption and hashing operation allows the router to encrypt packets with high
performance and reliability.
The encryption card is optional. On a router installed with an encryption card, the main control board
functions to route IP packets and implement encryption-enabled VPN, while the encryption card functions
to encrypt packets.
