ATT System 25 Reference Manual

							Remote Administration Interface
Remote Administration Interface
Description
This feature provides dial-up access to the system’s administration port, either for a standard
system administration terminal or for a PC running Advanced Administration software.
Both read and write capability is provided with access to all system translation and fault tables. A
remote administration terminal can perform the same functions as the on-premises SAT.
Remote Administration allows remote access to the system by maintenance personnel, the System
Administrator, and others.
Security Considerations
See remarks appearing in the following section on “Remote Initialization and Maintenance Service
(RIMS).”
Interactions
Only one System Administration Terminal can be connected at one time.
Administration Requirements
Depends on the connecting arrangements selected (see below).
Hardware Requirements
Requires a remote SAT.
Requires that port #1 of the CPU/MEM CP be connected to: (1) a dedicated modem and dedicated
facility (private line or CO trunk), or (2) a dedicated modem connected to a tip ring station port, or
(3) an ADU connected to a data line port. See the “System Administration” feature description for
additional information. Connectivity information is also provided.

							Features and Services
Remote Initialization and Maintenance Service (RIMS)
Description
Remote Initialization and Maintenance Service (RIMS) provides an AT&T technician remote access
to System 25. Using the RIMS feature, the technician can do System 25 initialization, ongoing
administration, and maintenance.
The remote administrator can initialize translations after the system is installed. Unless a hardware
change is required, the remote administrator can do ongoing administration without having to visit
the customers site. Similarly, to troubleshoot a problem, a technician can call the RIMS port and
check the Error Log to determine the probable cause of the trouble. The technician can clear
alarms remotely and decide whether a service dispatch is necessary.
Considerations
RIMS may not be available in some areas of the country.
Security Consideration
Potential Abuse of the Feature
Unauthorized access could disrupt your system programming or activate features that would permit
making long distance calls through-System 25.
Techniques for Minimizing Abuse
1. The System Administration capability of System 25 is protected by a password. Follow secure
password procedures as described below:
Choosing Passwords
Passwords should be as many digits as possible, and should not be obvious. Avoid those with
ascending digits (e.g.,1234), the same digits (e.g., 0000), digits corresponding to the
employee’s name (e.g., 5646 for John), the current year (e.g., 1993), the same number as
extension (e.g., extension 3455, password 3455), reverse extension (e.g., extension 3455,
password 5543), numbers that identify the user (e.g., social security, employee ID, room
number, etc.)
Establishing a Policy
As a safeguard against toll fraud, change passwords frequently. Set password expiration times
and tell users when the changes go into effect. Changing passwords routinely on a specific
date (such as the first of the month), helps users to remember to do so.

							Remote Initialization and Maintenance Service (RIMS)
2. If you have a special telephone line connected to your System 25 for Remote Administration,
do one of the following:
l Unplug the line when it is not being used.
l Install a switch in the line to turn it off when it is not being used.
l Install a security device, such as AT&T’s Remote Port Security Device.
In addition, keep the Remote Administration telephone number secret. Only give it to people
who need to know it, and impress upon them the need to keep it secret. Do not write the
telephone number on the System 25, the connecting equipment, or anywhere else in the
system room.
3. If your Remote Administration feature requires that someone in your office transfer the caller
to the Remote Administration extension, impress upon your employees the importance of
transferring only authorized individuals to the extension.
Interactions
A call to the RIMS port is logged by SMDR.
Administration Requirements
For a RIMS call to be made during initialization, at least one voice station and one trunk must be
translated. A “full-default” cold start can provide these translations.

							Repertory Dialing
Repertory Dialing
Description
This feature allows multiline voice terminal users to store a telephone number, account code,
or feature access code in the system’s memory and associate that number with a REP DIAL
button. Pressing REP DIAL is equivalent to dialing the stored number. Individual numbers
can be up to 28 digits in length.
Programming the number is accomplished from the user’s voice terminal. Programming
procedures and other information can be found in the “Program” feature description.
Should the user attempt to enter more than 28 digits, Reorder Tone will be given.
The user can press REP DIAL under any of the following conditions:
1.When off-hook receiving Dial Tone
2.   When off-hook on a call on which more dialed digits are expected
3.   When off-hook on a call and connected to an outgoing trunk (End-to-End Signaling
might apply in this case)
4.   After pressing ACCT ENTRY or dialing the Account Code Entry access code.
When REP DIAL is pressed, the button’s status LED lights briefly and then goes dark.
Considerations
Repertory Dialing simplifies dialing long or frequently called numbers, and allows one-button
access to many features.
Interactions
The following features interact with Repertory Dialing.
Account Code Entry:An Account Code may be stored on a REP DIAL button. The REP
DIAL button should be pressed at the point where the account code would normally be
dialed.
Bridging of System Access Buttons: If a station user selects a bridged appearance for an
outgoing call and then presses a REP DIAL button, the digits programmed into the button are
outpulsed as they would be if the user had selected one of the station’s own System Access
buttons.
Calling Restrictions:A user can not use Repertory Dialing to access a number that he or
she is restricted from dialing.

							FEATURES AND SERVICES
Display: When a call is placed by pressing a REP DIAL button, the characters stored are
displayed. If V was programmed to store a pause, P is displayed in the position of the V .
If V was stored by programming # V , only V is displayed.If the button is not programmed,
REP DIAL is displayed.
Following/Forwarding: The associated activation and deactivation sequences (or portions of
them) can be stored on REP DIAL buttons.
Last Number Dialed: A number called by pressing a REP DIAL button is saved by the Last
Number Dialed feature.
Speed Dialing:Numbers already stored as System Speed Dialing numbers can also be
stored as Repertory Dialing numbers.Storing a System Speed Dialing code (#100-#189) on
a REP DIAL button saves memory space (compared to storing the whole number again on a
REP DIAL button).
Virtual Facilities: Virtual Facility codes can be stored on REP DIAL buttons.
Administration Requirements
Voice Terminal Port:
l Assign Repertory Dialing (REP DIAL) buttons.

							Send All Calls
Send All Calls
Description
This feature allows multiline voice terminal including ATL cordless telephone users to turn off
their ringers and invoke a“do not disturb” condition toward incoming calls. In addition,
users who have coverage or bridged appearances will have those calls directed immediately
to their covering and/or bridging stations, without the normal system ringing delay. Send All
Calls also allows covering users to temporarily remove their voice terminals from the
coverage path.
This feature is activated by pressing the SEND ALL CALLS button. It is deactivated by
pressing the button a second time.
Considerations
Send All Calls gives the user the option of having incoming calls sent directly to coverage or
making the terminal busy to incoming calls without sending them to coverage. The feature is
intended for occasional or temporary use.
Send All Calls must be assigned to a button that has a status light. The light turns on when
the feature is in effect.
The following types of calls always ring at a station, regardless of the status of Send All
Calls:
l Automatic Intercom calls.
l Directed Night Service calls.
l Calls to an extension number that is logged in at the station.
Note:Calls to a floating extension number do not ring when Send All Calls
is in effect.
l Calls returning to a DTAC on RTN-BUSY or RTN-DA buttons.
Send All Calls cannot be assigned to a SLAC. The Attendant Position
a similar capability.
When Send All Calls is in effect at a station and incoming calls are
ringing at the sending station is not necessarily canceled completely.Busy feature provides
directed to coverage,
A single-ring reminder
for incoming calls is optional, assigned by the System Administrator for each Send All Calls
button.
On calls to non-busy stations where Send All Calls has been activated, the callers hear
ringing until a covering station answers, or,if the station is not covered, until the call is
dropped.
2-281 
						

							FEATURES AND SERVICES
Interactions
The following features interact with Send All Calls.
Bridging of System Access Buttons:The principal station can be administered so that
pressing the SEND ALL CALLS button will send ringing for incoming calls to its coverage
stations only, to its bridging stations only, or to both.
If ringing is sent to a Bridged Access (BA) button via Send All Calls, and if the BA button is
administered to not receive ringing, the call will flash (but not ring) at the BA button. If
ringing is sent to a BA button via Send All Calls, and if the BA button is administered to
receive ringing (immediate or delayed), then the call will ring immediately on the BA button.
Callback Queuing: Callback attempts to the originator are not affected by Send All Calls.
Call Waiting: A busy station with Send All Calls activated will receive call waiting tones; the
caller will hear special ringback.If the busy station then goes on-hook, single-ring reminder
will not be given for that waiting call.
Coverage (General):Send All Calls works in conjunction with the Coverage features at
covered and covering stations.At stations not associated with Coverage, Send All Calls
simply serves to silence the ringer on incoming calls; no redirection occurs.
If a station is translated to not send ringing to coverage when calls to this station are
unanswered, the Send All Calls feature overrides this instruction (ringing will be sent).
If a covering station activates Send All Calls, the station is removed from the coverage path
completely. Coverage calls will not be directed to the station.
Coverage, Group:If a station with Send All Calls activated has group coverage and all the
coverage receivers are busy, a call waits at the station while the system periodically checks
for an idle receiver. When one becomes available, the call is directed to the covering station.
Coverage, Individual:If a station with Send All Calls activated has only individual coverage
and all coverage receivers are busy, a call stays at the station; it does not go to coverage.
Display: When Send All Calls is invoked, the sending station still receives incoming call
information.If the calls are being sent to coverage, the proceeding-to-coverage descriptor
“c” appears in position 16.
Screen 1146 Pearson,M c
Distinctive Ringing:Normal audible ringing is turned off for incoming calls when Send All
Calls is activated, unless single-ring reminder is administered.
Forwarding: Forwarding supersedes Send All Calls.A call forwarded from a station with
Send All Calls activated will not go to coverage or to bridging stations unless the call is not
answered at the forwarded-to station and returns. After returning, the call routes according
to the Send All Calls feature.
2-282 
						

							Send All Calls
Hands-Free Answer on Intercom: Activating Send All Calls will cause an active AUTO ANS
button to turn off. As long as the Send All Calls feature is in use, AUTO ANS cannot be
turned on.
Line Status Indications:The line status lights still flash for incoming calls when Send All
Calls is in effect even though normal ringing is cut off.The lights stop flashing when the
calls are answered by a covering station or dropped by the caller.
Personal Line:Ringing on Personal Lines is turned off by activation of Send All Calls
whether the station is the principal (owner) of the line or not.Personal Line calls follow the
coverage arrangements of the principal station.If the principal station is not covered, the
call will simply stay at the principal station until dropped (even if other stations with that
Personal Line have coverage).
Administration Requirements
Voice Terminal Port:
l Assign Send All Calls button.
l Assign single-ring reminder if desired.
l Send ring to bridged stations only, to coverage stations only, or to both?

							FEATURES AND SERVICES
Speaker
Description
Some 7300H-series voice terminals have a built-in loudspeaker that allows on-hook dialing,
group listening, and monitoring of call progress signals. The terminal user turns on the
speaker by pressing the SPEAKER button.Pressing the button at an idle terminal has the
same effect as lifting the handset: the user is connected to the selected line and hears Dial
Tone. An associated LED is lighted when the Speaker is on. Speaker volume may be
adjusted by the terminal’s volume control located on the left side of the set.
The speaker and associated LED are turned off by pressing SPEAKER again or by lifting the
handset. The latter operation connects the handset to the associated voice channel. When
using the handset, pressing SPEAKER will turn on the speaker to support the Group Listen
feature; pressing SPEAKER again will turn off the speaker and associated LED. Note that
once the user has lifted the handset, it is possible to return to “hands-free” operation only
by putting the call on hold, hanging up the handset, then reconnecting the call by pressing
SPEAKER. Hanging up the handset will terminate the call whether the speaker is on or off.
Note:The built-in speaker provides one-way communication (listen only). The user
must pick up the handset to converse.
Considerations
The built-in speaker supports group listening, monitoring of calls (e.g., while waiting on hold),
and on-hook dialing.
Hardware Requirements
Only 7300H-series (MERLIN) voice terminals with a SPEAKER button support this feature.
Sets with a SPEAKERPHONE button have full speakerphone service, which provides two-
way, on-hook calling.
