Item MSCA MSCB

ESM slot 2 2

VCPM slot 1 1

VPM slot 4 0

NOTE:

• MSC (multi-service card) is installed in the slot provided on the backplane of the MSR 50 routers to carr

various service modules.

• MSCA is designed to work with MPUF while MSCB must be applied with MPU-G2.

ESM module

Installed on an MSC, 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.
