Chapter 3 Installing the Cisco AS5400 and Cisco AS5400HPX Universal Gateways
Connecting to the Network
•
Use an E1 cable to connect each E1/PRI port to an E1 channel service unit (CSU) or data service
unit (DSU). (See
Figure 3-8
.)
Note
If you choose a port with 75-ohm input impedance, use an RJ-45-to-75-ohm
coaxial cable adapter and plug it into that port. Use software commands to choose
a particular port and the line termination on that port. For information on software
commands, refer to the
Cisco AS5350 and Cisco AS5400 Universal Gateway
Software Configuration Guide
.
Warning
The E1 interface card may only be installed in an ACA-permitted customer equipment or
a Data Terminal Equipment (DTE) that is exempted from ACA’s permit requirements. The
customer equipment must only be housed in a cabinet that has screw-down lids to stop
user access to overvoltages on the customer equipment. The customer equipment has
circuitry that may have telecommunications network voltages on them. To see
translations of the warnings that appear in the publication, refer to the
Regulatory
Compliance and Safety Information
