Chapter 3 Installing a Cisco 7100 VPN Series Router
Connecting to the Network
Note To ensure compliance with EMI and European certification standards for emission control
(EN55022/CISPR22 Class B for radiated emission levels), the Tx and Rx cables should be tied together
along their entire length, and ferrite beads should be installed on each cable near the Tx and Rx
connectors.
To connect the ATM T3 or E3 port to the network, use the following procedure:
Step 1 Attach the appropriate coaxial cable directly to the receptacle on the router. (See Figure 3-13.)
Step 2 Attach the network end of the cable to the external synchronous serial equipment.
