Message Register Audit 
Description When this feature is enabled, the Attendant can print out the contents of 
the Message Registers and optionally clear them. The printout consists of 
several lines. The first line is the Message Register Audit header and has 
the following format: 
MM/DD hh:mm ROOM REGISTER 
l MM/DD - month and day . 
l hh:mm - time-of-day (24-hour clock) 
l hh:mmP - time-of-day (12 hour clock, PM). 
The remaining jines are of the same format. They provide the extension 
number and its Message Register contents 
as follows: nnnn - xxxx 
(repeated four times across the page), where nnnn is the extension number 
and xxxx is the contents of the Message Register. 
Conditions l A printer is required; refer to PRINTER PORT in this Section.

Pickup Groups - 
Description 
This feature assigns an extension to a Pickup Group and permits the 
extension to answer any call directed to any extension in that 
Pickup 
Group by dialing the Dial Call Pickup Access Code. 
Conditions 
l A maximum of seven Pickup Groups are permitted per system. 
l This feature cannot be originated by an extension with a call on 
Consultation Hold. In this case, if a pickup is attempted, then the 
originating extension receives reorder tone and must flash the 
switchhook to return to the held call.

							Appendix A 
NOTES ON TOLL FRAUD 
General 
A.1 The SX-50 PABX Customer Data Entry (CDE) Command registers contain 
programming parameters that allow for highly customized and flexible toll restriction 
applications. However, incomplete or careless programming can allow for the 
possibility of toll fraud - unauthorized toll calls by internal or external callers. 
SX-50 
PABX systems using Direct Inward System Access (DISA), or those interfaced with 
COV or ONS based voice mail/auto attendant (J/M/AA) systems are susceptible to 
unauthorized users as well. 
Precautions can be taken during programming of the SX4OPABX system to minimize 
toll call abuse. 
ARS and Digit Comparison Strings 
A.2 7011 restriction is achieved by analyzing the digits dialed by a user. Therefore, ARS 
digit strings form the basis of all toll control plans. ARS digit strings are programmed 
. into comparison tables using command 700. The system will route a call by 
A.3 comparing the digits dialed to the digit strings in the digit comparison table and finding 
the closest match. If no match is found, ARS will route the call on the default trunk 
group dialed, since the first digit of the string must always be a valid trunk group 
access code. 
You should be as explicit as possible with the ARS digit strings. For example, use 
entries of 91 NX rather than simply 91, where N is a digit 2 to 9 and X is a digit 0 to 9. 
After all of the 91 NX entries are input, enter 91 by itself at the end and do not program 
a route list in the time of day table associated with this entry. In this way ARS will not 
time-out and route the call. Time of day tables arefound in CMD 701 to 746. Similarly, 
ten entries of the form 9X should be created to cover all local long distance dialing. 
More digits may be required for each entry, depending on the application. 
An effective way to ensure that calls will be blocked if the ARS digit strings are 
incomplete and the system cannot find a match is as follows. Use only leading digit 9 
in the digit comparison table. 
Program 9 as the access code for trunk group 1. Do not program any trunks in trunk 
group 1. Program the trunks in the trunk groups 2 through 6 as necessary. Restrict all 
users from all trunk group access in their class of service. When a user dials an external 
number resulting in a match in the digit comparison table, the call will route according 
to the programmed route lists. If there is no match, then the call will route on the default 
trunk group dialed (trunk group 1, access code “9”). However, the call will be blocked 
because there is no access to trunk group 1, and there are no trunks in the group.

							Features Description 
1 “ARS Routing” Class Of Service 
A.4 
Any device in the system that can listen to dial tone such as stations, Dial-in trunks or 
DISA trunks, should be programmed with a Routing Class of Service (KS). The 
RCS is used in the ARS time of day tables to either route or block calls depending if 
a route list is specified. If no route list is specified, the call is blocked. It is also 
possible to assign the attendant console an RCS. - 
Verified Authorization Codes 
A.5 Veriiied authorization codes (I/AC) are available with software Generic MS53154 and 
later. A VAC can be associated with a certain COS and RCS in CMD 600. When a 
user dials a VAC, the device he is using acquires that COS and RCS. This can be 
useful in toll restriction applications such as special DISA. 
Note: the more digits used in an account code, the more combinations possible. 
Therefore, it is best to use VAC codes of eight digits in length to make it less likely that 
unauthorized users will discover the code by trial and error. 
DISA and Dial-h Trunks 
A.6 A DISA application offers the greatest potential for unauthorized use by external 
callers. Each DISA trunk should have an RCS assigned. Consideration should be 
given to toll restriction for all DISA trunks. The trunk also has a class of service, and 
outgoing trunk ‘access can be denied completely. Also, entry of a verified account 
code can be required before trunk access is allowed, or toll calling is permitted. This 
is possible because a COS and RCS are associated with the VAC. This functionality 
is known as Special DISA. A Dial-in trunk, such as an E & M tie trunk quite often 
presents a caller with dial tone. A Dial-in trunk should be assigned a COS and an 
RCS in CMD 5XX Register 1, bits E and H, so that it can be directly prevented from 
dialing out on another trunk. A VAC could be entered to allow specific users to acquire 
outgoing access. 
ONS or COV Interfaced Voice Mail / Automated Attendant Systems 
A.7 Toll control should be considered for any voice mail/auto attendant peripheral system 
that may be connected to the SX-50 PABX. Many of these types of systems perform 
a blind transfer based on any digit sequence dialed by the incoming trunk. This could 
result in long distance calls being made via the VM/AA ports if they are not toll 
restricted. VM/AA ports should be treated in the same manner as a regular 
subscriber port. 
.If the VM/AA system requires station ports looped back to trunk ports for message 
sending, there is the possibility of the incoming trunk obtaining dial tone when the 
VM/AA port hangs up. In software Generic MS53/54and later, this is controlled by the 
“Disconnect Tone” options in CMD 100, register 3, bit h, i, and j, and in COS 
programming “Voice Mail Port”, register 3 bit k. Any port used in this fashion should be 
105 A-2 Revision O/August 1994 9104-091-105-NA Issue 5  
						

							Notes on Toll Fraud 
completely toll restricted, and should have the minimal COS options enabled. Software 
- Generics MS50 and MS51 do not have the capability of returning dial tone when a 
station port hangs up. 
System Abbreviated Dial 
A.8 
In the SX-50 PABX, system abbreviated dial (speed call) can be programmed to 
bypass ARS. By default, speed call will use ARS and therefore toll restriction can be 
applied based on the digit sequence. Access to abbreviated dial is controlled by 
COS options. _ 
Abbreviated dial entries using manually inserted digits should be used with caution. 
Specifically, a speed call entry consisting entirely of manually inserted digits in the form 
93xX could potentially bypass all toll restriction imposed by ARS, depending on the 
digits dialed. Abbreviated dial entries of this form should be avoided. 
Passwords and RMATS 
A.9 All SX-50 PABX systems that have modems connected for RMATS dial up access 
should have the system security code changed from the default 7772. Likewise, the - 
RMATS security code should be changed from the default. Precautions should also 
be taken to prevent internal users from accessing CDE. This can be done by 
changing the user security code and by setting switch 1 on the control card to open 
(read.only).
