# 3 J1 Information

Overview

This chapter provides information on J1 configuration.

The J-ONE card supports 16 J1 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. The card can be used with, or instead of, the existing four-span SJ1LC. The product hardware includes a line card and input/output (I/O) cards.

For PPL Component Addressing information regarding J1, 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 J1 cards.
