Configuring Serial Interfaces for E1- and T1-Carrier Lines
Using the Serial Module for E1- or T1-Carrier Lines
Serial Module for the ProCurve Secure Router
The ProCurve Secure WAN serial modules are used when the public carrier
provides an external CSU/DSU for an E1- or T1-carrier line. (See Figure 5-2
on page 5-5.) ProCurve Networking offers two serial modules:
■ one-port narrow module
■ eight-port, or octal, wide module
If your company is the United States or Canada and your public carrier does
not
provide an external CSU/DSU, you must purchase and use a T1 module.
If your company is in another country and the public carrier provides only
a CSU, you must purchase and use an E1 module. (For instructions on
configuring these modules, see
Chapter 4: Configuring E1 and T1
Interfaces
.)

The ProCurve Secure Router serial modules are standards based. Specifically,
they support the following standards:
■ U.S. Federal Communications Commission (FCC) Part 15 Class A
