ProCurve Secure Router Modules
ProCurve Networking provides several E1 and T1 modules, which are
described in the next sections.
E1 Modules with a Built-in DSU
If your public carrier does not provide an external DSU, you should use one
of the E1 modules, which include a built-in DSU:
■ one-port E1 module
■ two-port E1 module
■ eight-port wide-option module (ProCurve Secure Router 7203dl only)
Supported Standards
The ProCurve Secure Router E1 modules are standards based. Specifically,
they support the standards listed in Table 4-1.
