# 4 E1 Information

Overview

This section contains information on E1 configuration.

The E-ONE card supports 16 E1 spans. If you do not need all 16 spans, you can buy the card with fewer spans. When your needs increase, you can buy product licenses to enable more spans, two at a time.

For PPL Component Addressing information regarding E1, refer to PPL Component Addressing Information in the API Reference.

Refer to Configuring SS7 Virtual Spans in the Developer’s Guide: Common Channel Signaling for information on virtual E1 cards.

Important! If the E-ONE card is not responding during frame synchronization, you must take it out of service and bring it back into service.
