When
Call Screening
is set to
Ansr if SN0. . .9
, an incoming call
is not answered if the Call ID received from the switch does not
match a stored number. Depending on the switch type, the Call
ID may be presented in either a seven- or ten-digit format. The
ISU 2x64 displays the Call ID for all dumped calls in the
Status
Buffer
. See Status Buffer on page 20 for more information.
Because different switches handle calls and Call ID differently,
first find out if the switch uses a seven- or ten-digit Call ID for-
mat. Use the following procedure to determine if a seven- or ten-
digit Call ID (phone number) should be stored.
1.
Select
Ansr if SN0. . .9
under
Call Screening
.
2.
Store the seven-digit number in SN0.
3.
Place a call to the ISU 2x64 with the stored number to see if it
answers properly.
4.
If the ISU 2x64 does not answer the call, check the Call ID
message in the Status Buffer. More than likely, the Call ID
number will be a ten-digit number.
5.
Reenter the number in SN0 as it is displayed in the Call ID
message and test
Call Screening
again.
SBus Termination
Use the SBus Termination option (see Figure 6-12) to select 100
ohm termination resistors for the S/T interface on ISU 2x64 units
that are equipped for the ISDN S/T interface. These units (part
numbers 1200051L2, 1200051L4, 1200051L5, and 1200051L6) con-
nect to the S/T interface of an NT1 device or the S/T line card.
