Configuring Serial Interfaces for E1- and T1-Carrier Lines
Serial Interface: Configuring the Physical Layer
If you have an EIA 530 cable that you purchased from another vendor, the
ProCurve Secure Router supports it. You can also use Figure 5-6, which shows
the pinouts for EIA 530, to create this type of connector.

Whichever cable you use, the serial module supports up to 10 Mbps.
