 Connection to a PC
In some cases, such as when you configure the equipment, it is possible

II.3.2.1. ISDN Port (Optional)
The ProntoNetLC incorporates an ISDN terminal adapter that allows connection
to a basic ISDN line (2B+D). It supports different ISDN protocols (EURO_ISDN,
DMS100, AT&T 5ESS and NAT1). To connect there are two RJ45 connectors: one
for connecting to an S/T interface and the other for connecting to a U interface.
