Network Data Encryption Module (NDEC for short) supports IPSec protocol, speeds
up the encryption processing of IP packet by means of hardware, thus, provides
encryption features of high performance and high reliability for routers.
When NDEC module is inserted, the main board of the router handles IP packet
forwarding and implements the VPN with encryption features, then the NDEC will
complete the task of encryption.

The main functions of this MIMM include:
Working in this mode, the module can provide the subscribers with the
low-speed accessing service at the speed of Nx64kbps or 56kbps, given N is
smaller than or equal to 128.
Working in T3 mode, the module can transmit/receive and process one channel
of T3 fast traffic, as well as provide the accessing of T3 traffic.
