75.1. How to configure ISDN ports to connect PBX or ISDN lines
	Chapter 75. HowTo - CTI system

Physical connections:

Verify that an ISDN card (PB44X, BRI-HFC4, BRI-HFC8) is installed in the Abilis. If the card isn't present, insert it in a free PCI slot.
Connect the ISDN card to NT devices and to PBX.

The basic parameters that must be configured are:

side:NT (if the CTI Port is connected to PBX) or TE (if the CTI Port is connected to ISDN lines).
line:PP (if the ISDN line is Point-to-Point) or MP (if the ISDN line is Point-to-Multipoint).

Let's see how to configure a BRI card: in the standard configuration, the CTI Ports 31 and 32 are configured towards the PBX, while the CTI Ports 33 and 34 towards ISDN lines.

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a dev:bri4-1	Add an ISDN device (e.g. BRI4-1).
s ctip:31 side:nt line:pp descr:to_PBX	Configure the port behaviour, the line type (`PP` or `MP`) and the description of the CTI Port.
s ctip:32 side:nt line:pp descr:to_PBX	Configure the port behaviour, the line type (`PP` or `MP`) and the description of the CTI Port.
s ctip:33 side:te line:pp descr:to_ISDN_line_(PP)	Configure the port behaviour, the line type (`PP` or `MP`) and the description of the CTI Port.
s ctip:34 side:te line:pp descr:to_ISDN_line_(PP)	Configure the port behaviour, the line type (`PP` or `MP`) and the description of the CTI Port.
save conf	Save the configuration.

On a working Abilis, a system restart is required to make the BRI4-1 device and the CTI Ports running.

Tip

	Tip
To know if the ISDN line is `PP` or `MP`, display the statistics of the CTI Ports and verify the `DISC` parameter. If the value is different from zero, the line is `MP`.
