Line Number
The BRI line number. For information only

TEI: Default = 0
This is the Terminal Equipment Identifier number associated with the line. It is used to identify each device connected to a particular ISDN line. For Point-to-Point lines this is 0. It can also be 0 on a Point to Multipoint line, however if multiple devices are sharing a Point-to-Multipoint line it should be set to 127 which results in the exchange allocating the TEIs to be used by each device.
