PROGRAMMING FOR AN ISDN (T1/PRI) CARD VIA PC-DBA
ISDN (T1/PRI) technology is similar to the T1 (see page 155), by adding another option for digital trunking and allowing
you to increase the DX-120 trunk capacity (i.e., to 39 when including 16 analog CO lines). The ISDN (T1/PRI) also
adds Caller ID Flexibility (Inbound Number & Name, Outbound Number).
