System 25 Communications System
R3V3 Upgrade
Because of the North American Numbering Plan changes effective in 1995, many
customers have requested that their System 25 Communications Systems be upgraded
to R3V3. R3V3 contains the necessary changes so that customers who use Automatic
Route Selection (ARS), Pool Facilities, or Personal Lines can be compatible with the
network.
When you upgrade a System 25 Communications System to R3V3 for the Improved
North American Dial Plan (INPA), you must set various items in the system to minimize
customer problems following the upgrade.
In the INPA mode the following administration items are AUTOMATICALLY SET
(administering these items does not change their values) to the following values:
1.  Is the “1” prefix required to dial outside your area code
“YES”
(Menu 4 Action = 32, Data = 1)
2.  Is the “1” prefix required to dial toll calls within your area code?  “NO”
(Menu 4 Action = 33, Data = 0)
The only item that can be administered is the dialing plan for Home Area Code (HAC)
calls.
“Require 10 digits for HAC” (scroll)“YES/NO”
(Menu 4, Action = 37, Data = 0 for 7-digit dialing or 1 for 10-digit dialing)
Toll Restrictions/Dial Options
Home Area Code
This should reflect the Home Area Code (HAC) for the installing customer.
Set toll restriction options under Menu 4 (Basic Administration) or in the Advanced
Administration System (AAS); an example is shown in Figure 1.

May Toll-Restricted Stations Make Toll Calls In HAC?
This should reflect your customer’s decision to allow or disallow calls within the HAC.
Be aware that how you answer other questions may affect the operation of this feature.
To ALLOW toll-restricted stations to DIAL 911 (INPA) via Automatic Route Selection
(ARS), follow the example of Figure 1:
1.  Select “no” for “May toll restricted stations make toll calls in Home area code
(scroll).” This action may also be found under Menu 4 as Action 31.
2.  If toll-restricted stations are allowed to make toll calls within the home area
code (HAC), in the appropriate Toll Call Allowed List, enter 911 and any other
allowed central office code, or (...) for all central offices (COs).
To ALLOW toll-restricted stations to dial Directory Assistance in areas that require the
prefix “1” (1-411) in the INPA mode, take the following steps:
1.  Select Automatic Route Selection (ARS).
2.  Enter the X11 code table.
3.  Direct 411 to a vacant ARS pattern.
4.  Return to Main Menu and select Toll Allowed/Disallowed Lists.
5.  Enter 411 and any other allowed central office code or enter three dots (...) for
all central office codes in the appropriate toll-allowed list.
6.  Proceed to Speed-Dialing/Virtual Facility Number (VFN).
Page 2CIB 3181 (107682924)
Issue 1, November 1995 
						

							CIB 3181
System 25 R3V3 Setup
7.  Administer a VFN with facility access code and pause, i.e., (100*).
8.  Place the VFN in the pattern to which 411 is directed.
9.  Perform digit translation on the selected VFN to:
a.
b.
c.
d.
Enter Home Area Code.
Leave digits to remove at “0”.
For “digit pattern to add for calls within this NPA,” enter “1”.
Do not enter any digits for calls outside this NPA.
THE CUSTOMER NOW DIALS 411 (not 1-411) FROM ALL STATIONS, toll-restricted
and non-restricted. The system will prefix the digit “1” when 411 is dialed.
To allow Toll-Restricted stations to dial 1-411 when the customer uses Pool Facilities
instead of ARS, the following items should be administered:
1.
2.
Assign a Facility Access (Pool) button on the station. Single-line stations use
the facility access code.
In the appropriate Toll Allowed List, enter 411... (*.* wild card) and other
allowed central office code or 3 dots (...) for all office codes.
Non-restricted and restricted stations dial Facility Access Code (FAC) plus 1-411.
Dial Plan Options
Select “yes” for INPA dialing. Otherwise, select “no” (Action = 37, Data = 1).
In areas that deviate from the normal INPA numbering plan, i.e., where three dial
options (7, 10, and 11 digits) are used, do the following:
1.
2.
3.Select “yes” for INPA dialing requiring 11 digits (Action = 36, Data = 1).
Select “no” for “Requires 10-digit dialing for HAC calls” (Action = 37, Data = 0).
This permits 7-digit dialing in the HAC.
Implement 10-digit dialing in one of two ways:
lUsing Virtual Facility Numbers (VFNs): The customer dials 1 + NPA + AAA
+ AAAA, 11 digits (where N = 2 to 9, P = 0 to 9, and A = 0 to 9) for all 10-
and 11-digit numbers. Numbers that require 10 digits use a separate ARS
pattern with a unique VFN to strip the leading digit (“1”). The required 10-
digit numbers are entered in the Other Area Code Exception list and sent
to the pattern that uses the VFN.

CIB 3181
lUse of pool facilities: Non-restricted stations can dial all numbers (7, 10, or
11). For Toll-Restricted Stations, enter the 3-digit area code (NAA) for 10-
digit numbers and 6 digits (NAA-AAA or NAA-..., wild card *.*) for 11-digit
numbers in the appropriate Toll Call Allowed (TCA) list. This satisfies the
situation where an area code is added and central offices do not exist in
the originating area code with the same 3 digits as the added area code.
Additional Area Codes for ARS Use
New area codes are not part of the default translations for the new System 25 upgrade.
YOU MUST enter the new area codes as they become available. ADD the following
known new area codes to the appropriate pattern either in AAS to the NAA tables or in
Menu 11, Actions 300 and 301 in basic administration:
l   210l   410l   610l   864
l   281l   423l   630l   910
l   310l   441l   710l   941
l   320l   510l   770l   954
l   334l   520l   810l   970
l   352l   540l   847l   972
l   360l   562l   860
Some of these numbers existed in previous versions of the system but were lost when
the system was cold started and the upgrade reload was made.

Upgrade Adjustments
When you upgrade your System 25 Communications System to R3V3, certain items
change to default values or change status. Check the following and reset or adjust
them as necessary to minimize any system problems after the upgrade.
Date and Time
After an upgrade, the date and time are set at default values. If you do not set the
system to the current date and time, the SMDR reports and ARS time-of-day routing will
be affected.
Direct Group Calling
Check to see if the system translations support a Direct Group Calling (DGC) delay
announcement. If they do, remove the current announcement and retranslate via the
ACTION/DATA or AAS with the R3V3 information and personal dial code (PDC). Follow
these steps:
1.   To untranslated the current announcement machine:
a.  Select 1 (PORT) from the Main Menu.
b.  At Action =, enter 1.
CIB 3181 (107682924)Page 7
Issue 1, November 1995 
						

							System 25 R3V3 SetupCIB 3181
c.  At Data =, change the value from “255” to “0”.
1.   To add or retranslate an announcement machine, do the following:
a.  Select 1 (PORT) from the Main Menu.
b.  At Action =, enter 1.
c.  At Data =, enter 255.
d.  At Action =, enter 2.
e.  At Data =, enter the assigned PDC.
f.  At Action =, enter 3.
g.  At Data =, enter 1 (dial accessible).
h.  Press “a” for action.
i.  At Action =, enter 90.
j.  At Data =, enter “ID of announcement 11 characters or less.”
Add the assigned DGC announcement to the DGC, and set the timing for the
announcement activation. Main Menu 4, Action 7, which set the number of rings before
the unanswered DGC calls were sent to the delay announcement, no longer exists.
Instead, the new translations set the number of seconds before a DGC call is sent to
the announcement. (Four seconds = one ring cycle.) The customer may now have up to
32 individual DGC announcements. To change the time interval after which an
unanswered DGC call is sent to the announcement, follow these steps:
1.
2.
3.
4.
5.
6.Select 6 from the Main Menu.
At DGC =, enter the group number.
At Action =, enter 20.
Under Data, enter “PDC ASSIGNED TO ANNOUNCEMENT.”
At Action =, enter 21.
At Data, enter the TIME INTERVAL IN SECONDS (1-255 seconds)
Forwarding, Follow Me, and FPDCs
Following any tape restore or upgrade procedure, you must log all Floating Personal
Dial codes (FPDCs) back into the appropriate stations. Until you re-establish them, Call
Forwarding and Follow Me are not active.

Voice Messaging
If you upgrade your voice messaging from a 3B1 to a 6386 WGS or higher computer,
you must correct system options:
1.  Select 4 from the Main Menu.
2.  At Action =, enter 96.
3.  At Data =, enter:
l     0 for 3B1
l     1 for 6386WGS or higher computer
Call Accounting
Because R3V3 upgrades include NPA changes, 10-digit dialing, and 15-digit
international calling, check the Call Accounting software used. Current Call Accounting
releases are not compatible with INPA. If the Call Accounting package is provided by
AT&T, Marketing should advise the customer of the need to upgrade this package. If
the package is provided by another vendor, notify the customer.
Callback Queuing
Explain Callback Queuing to customers who upgrade from a pre-release R2 system.
Callback Queuing did not exist in their previous system operations, and this can cause
some confusion in the operation of the system.
