Use line
Press CHANGE and enter the number of the line the I-RAD will use to send 
an alarm code. The line cannot be a target line, a line that is private to a DN, 
and you cannot use a line pool code.
Press 
CLR to choose None.
Retry time
Press CHANGE and enter the length of time in minutes the I-RAD will wait 
before trying the pre-programmed telephone number again. Enter a number 
between 1 and 50.
Press 
CLR to reset Retry time to the default (15 minutes).
Num. retries
Press CHANGE to select the number of times the system will retry the 
transmission of the alarm code: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Press 
CLR to reset the number of retries to the default (5 retries).
Tip - Unlike an external RAD, the I-RAD alarm 
reporting feature does not require you to set the baud 
rate or parity. Alarm reporting can use any lines which 
are not private to a DN or target lines.
Because alarm reporting is an internal system feature, 
alarms indicating major events such as a system failure 
may not be transmitted.
Tip - It is recommended that you program the system to 
make at least one retry of the alarm reporting telephone 
number.

ETSI: Network features (profile 2)
If you are using Profile 2 for your system, and your service provider 
supports the features on your ETSI ISDN lines, you can configure  your 
system to allow network diversion and/or Malicious Caller ID (MCID) 
recording.
To program these features:
1. With the display showing 
System prgming press ‘ until the 
display shows 
NetworkServices.
2. Press 
≠.  ETSI displays.
3. Press 
≠ Netwrk Redirection displays. 
4. Press 
CHANGE to choose either Y (yes) or N (no).
5. Press 
‘. MCID displays.
6. Press 
CHANGE to choose either Y (yes) or N (no). 
Malicious call identification (MCID)
The MCID feature allows the user to press ²¡áà to have call 
information recorded on the central office system for an incoming call on 
a specific line (ETSI PRI lines, only).
The user must invoke the feature code either during the active call or within 
30 seconds (time varies on different networks) after the caller hangs up. 
The feature will not work once the called party hangs up.
Note: This feature must be allowed in network programming for your PRI 
lines from your service provider.
The following information registers on the network:
called party number
calling party number
local time and date of the invocation in the network serving the  called 
user
service provider option: calling party subaddress, if provided by 
calling user)

Network Call Diversion
Norstar Network Call Diversion (NCD) is a network function that allows 
forwarding and redirection of calls outside the Norstar network when using 
an ETSI ISDN line. Functionality is similar to that of External Call 
Forward (ECF).
NCD redirects calls using the same line on which they arrive. Call forward 
is efficient since there is no need for additional outside lines.
Forwarding calls externally from an extension requires the user to enter 
either a Destination Code or Line Pool Access Code, and the number to 
which calls will be forwarded.
Examples of NCD include:
redirecting all calls from an extension to a mobile phone
forwarding calls to an external destination (rather than to voicemail), 
when an extension is busy or the user is unavailable.
Feature description
NCD is available only over ETSI ISDN lines. It can be invoked when calls 
are presented to Norstar/BST extensions over ISDN lines. The user must 
program the selected extension.
NCD is integrated with the following existing Norstar Call Forward 
features:
Call Forward Unconditional (CFU)—implemented on Norstar Call 
Forward All Calls (CFAC) 
²Ý, and Selective Line Redirection 
(SLR) 
²¡Ý, also referred to as Line Redirection. This is 
programmable by the user. 
Call Forward on Busy (CFB)—implemented on Norstar Call Forward 
Busy.
Call Forward on No Response (CFNR)—implemented on Norstar Call 
Forward No Answer. 
						

							ETSI: Network features (profile 2) / 237
P0992669 03Compact ICS 6.0 Installer Guide
For example:
When a call comes in on ETSI ISDN and is returned to a destination 
being serviced by ETSI ISDN, BTNR 191, Analogue or DASS2 lines, 
then ETSI Call Forward (CFU, CFB or CFNR) is used.
When a call comes in on ETSI ISDN and is returned to a private 
network destination over DPNSS, then External Call Forward (ECF) 
is used.
When a call comes in on DPNSS 1 and is returned on any line type 
except DPNSS 1, ECF is used. If that call is returned over DPNSS, 
however, then DPNSS 1 Diversion (DIV) is used. Refer to Network 
Call Diversion on page 236
When a call comes in on any other line type, such as AC15A, then 
again ECF is used. Note that under certain line conditions, ECF will 
not work; refer to Line Redirection restrictions.
Note:  In all cases, if NCD fails due to network errors or rejections, Norstar 
invokes ECF. If an outgoing line is unavailable, Norstar routes the 
call to the line’s prime extension.
Programming and restrictions
NCD features are accessed through existing Norstar features. Extensions 
requiring redirection must be programmed individually to either CFAC or 
SLR. CFB or CFNA must be set during programming. 
Allow redirect 
must be set to 
Yes for each extension, in Terminals&Extns/
Capabilities
.
Note:  Any other programming applied to specific lines and extensions 
take precedence, for example 
Restrictions(extns) under 
Terminals&Extns.
NCD is used as long as the affected lines are ETSI ISDN, and the affected 
DIA lines are accessible via ISDN lines. Incoming calls are diverted back 
to the ISDN. If NCD fails due to network errors, ECF is invoked. If ECF 
cannot be executed, the incoming call is routed to the line’s prime 
extension.
ATTENTION!
If a line is configured to appear on several 
extensions with redirection programmed, 
predicting which extension will divert the call is not 
possible. This should be considered during system 
configuration. 
						

							238 / ETSI: Network features  (profile 2)
Compact ICS 6.0 Installer GuideP0992669 03
An extension with CFB, CFNA and CFAC programmed will give priority 
to CFAC for diversion.
Selective Line Redirection
Selective Line Redirection (SLR), also referred to as Line 
Redirection, is enhanced for use with digital lines and operates 
in conjunction with NCD.
Diversion by SLR takes precedence over diversion by CFAC. 
An SLR line cannot be diverted by CFAC. If the call arrives 
on an extension with SLR programmed, a ring splash will 
sound (if programmed).
For information on SLR restrictions refer to Selective Line 
Redirection on page 238. For information on redirecting lines 
see Line Redirection in the Modular Plus System 
Administration Guide.
Programming Extensions
The User Interface for programming NCD is the same as for 
ECF.
Different types of Call Forward are available depending on the 
extension being programmed. Programming an extension to 
forward calls externally requires the user to enter a destination 
code or line pool number, in addition to the external phone 
number. Therefore, care should be taken to identify your 
network line types and record the available codes and line 
pools.

Enhanced Caller ID
When a Norstar/BST extension which has Call Line Identifier 
(CLID) active receives a redirected call due to NCD, the user 
will see the DN for the Calling Number. This is followed by a 
“>” and the redirecting number. This is displayed for as long 
as the call is active (alerting or answered) at that telephone.
If the alerting extension is not the CLID extension for that line, 
the line appearance can be pressed to briefly display the 
information. Pressing ²¡ÚÚ or INFO
 while the call is 
active invokes Call Info. Call Info on DPNSS displays the 
redirecting number and the reason for the redirection.
Note:  When Norstar requests that an incoming call be redirected by the 
distance network, Norstar does not inform the network of the 
redirecting DN. In this case, the diverted-to party will not see the 
diverting party DN.

Telco features
VMsg centr tel#s
If you subscribe to a voice message service outside your office, you can 
access it through your Norstar system. This setting specifies the external 
telephone numbers that are dialed by the Message feature to retrieve voice 
messages. Use 
≠, ‘, CHANGE, and the dialpad to enter 
the external number.
The default for each voice message center is No number.
Outgoing Name and Number Blocking
When activated, ²¡Úá blocks the outgoing name and number. 
When this feature is used, the call is flagged to the CO so that the name and 
number will not be presented to the person being called.
On feature supported trunks, a call blocking digit sequence is sent to the 
CO before sending the dialout digits. You can change this digit in System 
Prgrming and set it to the digit sequence recognized by the local CO for 
name and number blocking.
To program the Name and Number blocking digit, start with the display 
showing 
Telco features.
1. Press 
≠. The display shows VMsg ctr tel#s. 
2. Press 
‘ until the display shows ONN Blocking:. 
3. Press 
≠. The display shows Analog VSC or BRI VSC .
Tip - A telephone does not show that external voice 
messages are waiting unless Extl VMsg set is set to Yes. 
The setting is in CLASS assignment under 
Terminals&Sets.
You can program up to five voice message center 
numbers, but most systems require only one.
