116CHAPTER 3: MULTIFUNCTIONAL INTERFACE MODULES

■Read the mark identifying a port before you connect a cable to it, making sure it is the correct port. Wrong connection tends to damage interface modules and even the Router.

■As provisioned by Bell V, cables for FXS/FXO/E&M modules do not provide PGND wire. For this reason, a loop should be formed via the earth ground between the Router and the connected switch. In practice, the PGND wire of the switch can be connected to the chassis of the Router;

■To ensure the EMC of the whole Router, you should connect the end of the cable with ferrite core to the Router.

Step 1: Plug one end of the cable into the RJ-45 port on 2FXS/2FXO/2E&M;

Step 2: Connect the other end of the cable to:

■Telephone set, fax or AT0 loop trunk of telephone exchange, if you have installed an FXS module;

■Subscriber line of telephone exchange, if you have installed an FXO module;

■E&M trunk of telephone exchange, if you have installed an E&M module;

MIM-HNDE Module

Introduction High Network Data Encryption (MIM-HNDE for short) supports IPSec protocol, multiple hardware encryption/decryption and hash algorithm to speed up the encryption of the IP packets, featuring high-performance and high-reliability.

Insert MIM-HNDE module in the MIM slot of a low-end and mid-range modular router. The main board forwards the IP packets and implements the VPN with encryption feature which is complemented by encryption card.
