Request from the telephone company an ISDN line in a “Point To Point”
configuration with 2B1Q line code. Your ISDN line must be configured to
allow circuit switched data on both B-channels and signaling on the D-
channel. Request that the Telephone Company program your ISDN line
with the following attributes:
n
Maximum terminals set to 1 (this tells the switch that there is 1
terminal active on this line.)
n
Maximum B-channels set to 2; Actual User settings (this tells the switch
that you are an actual user and may use both B-channels
simultaneously.)
n
Circuit switched data set to 2; circuit switched data channel set to any
(this tells the switch that you may use both B-channels simultaneously.
The “Any” tells the switch that either B-channel can be used for data.)
n
Terminal type is Type A - Basic Terminal (this tells the switch you are
a basic ISDN terminal.)
n
Display set to Yes (this tells the switch that you have display
capabilities.)
n
Call appearance quantity set to 1 (this tells the switch that you want 1
appearance of your primary telephone number.)
n
Call appearance preference set to Idle (this tells the switch that your
software will make a positive choice of which cal appearance it will use
to initiate a call.)
The Telephone Company will also need to know any additional voice
features that you require on your ISDN lines. Examples of these features
are Caller ID and Call Forwarding. PLEASE REMEMBER TO SPECIFY A
LONG DISTANCE CARRIER.
