For Northern Telecom switches, the valid characters are any ASCII digit
except for the underline character (_). For National ISDN and AT&T switches,
only digits (0-9) are allowed.
TEI Values
A terminal endpoint identifier (TEI) is a number assigned to a terminal adapter
at subscription time. The central office switch uses this number to identify the
different terminal adapters that may be connected to the ISDN network. The
values 0 to 63 are called Manual or Fixed TEIs. These values are agreed upon
at subscription time and the terminal adapter must use the number to communi-
cate with the central office switch. If TEI assignment is automatic (dynamic),
the central office switch will dynamically assign a TEI each time that the ter-
minal adapter is connected to the ISDN interface and the unit power is on.
Voice TEI *!D3=
Data TEI !D3=
Directory Numbers !N1= and *!N1=
The directory number (DN) is the phone number assigned to the terminal
adapter. This number is supplied to the user at subscription time.
The directory number is a string with up to 24 characters. If the DN is entered
on command line with other commands, it should be isolated or set apart by
matching single or double quotation marks (' "), for example '1234' or "1234".
Quotation marks are not required if the command is on a line by itself.
The valid characters are: 0 - 9, *, and #.
