Line Options
To allow the system to route calls to the correct destination, you can assign a
telephone number consisting of up to 12 digits.
The factory setting is no telephone number is assigned. If you assign a
telephone number to a channel, it must match the number that is dialed by the
outside caller and sent to the system by the network. The numbers sent by the
network are furnished by the ISDN-PRI service provider. The number you assign
must also be unique within the same B-channel group and must be different
from the associated test telephone number. B-channel groups and test
telephone numbers are assigned later.
Planning Form Instructions
For all channels you plan to assign a telephone number:
1.
Transfer the information from the "Line Type" column of Key System From
2c System Renumbering — Line Jacks to Form 3c. Write the logical ID
and the number in the applicable column.
2.
Write the unique 12-digit telephone number furnished by the ISDN—PRI
service provider in the "Telephone Number" column.
If your business subscribes to the AT&T INFO2 automatic number identification
(ANI) service, you can assign the telephone number the system sends to the
network when outgoing calls are made on ISDN-PRI facilities. If the person
being called also subscribes to the same identification service, the telephone
number sent identifies who is calling.
The factory setting is that no telephone number to send is assigned. If you
assign a telephone number to send, it does not have to be unique since the
number is used only for identification and not for routing. The number assigned
can be up to 12 digits.
Note: The availability of the caller identification information may be limited by
local-sewing (caller's) jurisdiction, availability, or central office equipment.
