Speakerphone Adjunct
Description
The speakerphone adjunct permits users of voice terminals not equipped with built-in
speakerphones to place and receive calls without lifting their handsets. The adjunct has an
On/Off switch, a switch to temporarily mute the microphone, status lamps, and a volume
control (for incoming voice only).
All voice terminal features operate normally with the speakerphone adjunct.
Lifting the handset during speakerphone operation automatically turns off the speakerphone.
The speakerphone may be turned on during a call by pressing the On/Off switch and hanging
up the handset.
Considerations
Speakerphone operation allows users to perform other activities while carrying on a
conversation. Speakerphones also facilitate conference calls.
Interactions
The following feature interacts with Speakerphone Adjunct.
Headset Adapter Adjunct: A voice terminal cannot have both a speakerphone adjunct and a
headset adapter adjunct.

							Speed Dialing
Speed Dialing
Description
There are two types of Speed Dialing: (1) System Speed Dialing, and
Dialing.
System Speed Dialing:
Allows the System Administrator to store up to 90 numbers (maximum
length) that are accessible by dialing 3-digit codes from any voice or data(2) Personal Speed
of 28 characters in
terminal.
Examples of typical System Speed Dialing numbers include frequently-dialed DDD
(together with leading facility access codes for WATS, FX etc.) and account codes.
The following special characters may be used in System Speed Dialing numbers.
numbers
CHAR.FUNCTION
VProduces a 1.5 second pause. (Since System 25 does not have a
Dial Tone detector, judicious use of the pause character will help to
ensure that intermediate Dial Tones are obtained before more digits
are sent.)
# VTransmits an actual “ V ”.
# #
Transmits an actual “ # ”.
# 1xxRepresents a Virtual Facility code (where xx = 90-99). This may
appear only at the beginning of the stored number.
# 8Marks the beginning of End-to-End Signaling. (System begins
transmitting touch-tone signals to the far end switch.)
A user cannot use a Speed Dialing number for which he/she is toll restricted, outward
restricted, or facility access restricted.
System Speed Dialing Operation: To place a call using a System Speed Dialing number, the
user goes off-hook and presses the # button on the dial pad followed by the 3 digit code
assigned to the desired number.The system interprets the associated stored number as if it
were dialed directly. This includes analysis of the number for the various types of restriction.
This feature can also be used when entering account codes. After pressing ACCT ENTRY or
dialing “ V 0 ”,the user can enter a System Speed Dialing code. The stored number
associated with the code (the account code) will be listed in the SMDR report.
Multiline voice terminals users may assign System Speed Dialing codes to Repertory Dialing
(REP DIAL) buttons.
2-291 
						

							FEATURES AND SERVICES
Personal Speed Dialing:
Allows users to program up to twenty Personal Speed Dialing numbers (maximum of 25
characters in length) that are accessible only from their terminals. The numbers are
accessed by dialing associated access codes (#20-#39).
Personal Speed Dialing is authorized on a per-station basis through System Administration.
The System Administrator will inform users if they can use this feature.
Refer to the“Program”feature description for more Information about programming
Personal Speed Dialing numbers.
If enough storage space is available in memory to allow assignment of a Personal Speed
Dialing number, confirmation tone will be returned after each number is programmed. If not,
reorder tone will be returned.
Note:Personal Speed Dialing is voice terminal oriented, not PDC oriented. A user
who logs in at another terminal cannot use his/her Personal Speed Dialing
numbers.
Considerations
System Speed Dialing allows users to dial a number by simply dialing #100-#189. The
stored number associated with each code is (typically) a common-use phone number and is
programmed via System Administration.
Personal Speed Dialing allows users to program up to twenty numbers for their personal
use; these numbers can only be accessed from the terminal where originally programmed.
The system will compare the restrictions applicable for the voice terminal against the number
associated with the Speed Dialing code, then allow or deny the call just as if the number had
been dialed directly from the terminal.
Interactions
The following features interact with Speed Dialing.
Account Code Entry: Speed Dialing codes may be used to store account codes.
Bridging of System Access Buttons: Personal Speed Dialing is a station oriented feature. If a
station dials a Personal Speed Dialing code (#20-#39) while off-hook on a Bridged Access
button, the system will handle this call exactly as if the code was dialed from this station’s
System Access button.
Calling Restrictions:A terminal that is restricted from placing a particular call cannot avoid
restriction by using the Speed Dialing feature.
2-292 
						

							Speed Dialing
Data Terminal Dialing:System Speed Dialing codes can be entered during Data Terminal
Dialing. Personal Speed Dialing is not supported.
Display: When a call is placed by dialing a Personal Speed Dialing code, 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.
When a call is placed using a System Speed Dialing code, only the dialed code (#100-#189)
is displayed.
Last Number Dialed: A number called with a Speed Dialing code is saved by the Last
Number Dialed feature.
Personal Lines: The Speed Dialing feature is not accessible from Personal Lines.
Remote Access: Remote Access callers cannot use the Speed Dialing feature.
Repertory Dialing: Storing a System Speed Dialing code (#100-#189) on a REP DIAL button
saves memory space, compared to storing the whole number again on the REP DIAL button.
Speed Dialing: A Personal Speed Dialing number can include a System Speed Dialing code
only as the first four characters (but nowhere else). Personal Speed Dialing numbers cannot
include Personal Speed Dialing codes.System Speed Dialing numbers cannot include any
Speed Dialing codes.
Virtual Facilities: A Virtual Facility code may be used within Personal or System Speed
Dialing numbers. When used, it must appear at the beginning of the stored number (first four
characters).
Administration Requirements
System:
l Assign System Speed Dialing Numbers.
Voice Terminal Port:
l Allow/Deny Personal Speed Dialing on a per station basis.

							FEATURES AND SERVICES
STARLAN NETWORK Access
Description
The AT&T STARLAN NETWORK (STARLAN NETWORK) Access feature provides
connectivity between System 25 and a colocated STARLAN NETWORK. This connectivity is
provided by a combination of hardware and software elements. The STARLAN NETWORK
must use Release 2 software; System 25 is not compatible with Release 3 STARLAN
NETWORK software.
The STARLAN INTERFACE circuit pack (ZTN84) is the principal hardware element
connecting System 25 and the STARLAN NETWORK. One or more of these circuit packs
may be mounted in the System 25 cabinet(s). The STARLAN circuit pack (CP) communicates
with System 25 call processing over System 25’s Time Division Multiplex (TDM) bus. To
System 25, this circuit pack functions like a 4-port Data Line circuit pack (DLC). To the
STARLAN NETWORK, the STARLAN CP appears as a STARLAN NETWORK workstation.
Communication between STARLAN NETWORK equipment (workstations, servers, hosts) and
data terminals, PC6300s, and host computers connected to System 25 is provided by
firmware on the STARLAN CP and communications program(s) on the PCs and hosts. Two
communications programs are available to users:
l System 25 STARLAN NETWORK ACCESS (ACCESS)
ACCESS allows MS-DOS personal computers (PCs) connected (via the PC’s serial
port) to System 25 to communicate with DOS Servers on the STARLAN NETWORK
and to function as client workstations.The interface from the System 25 to the
STARLAN NETWORK is the STARLAN CP operating in bridge mode. Bridge mode
provides a transparent connection between the PC and the STARLAN NETWORK.
Personal computer users may access the STARLAN NETWORK just as though they
were connected to the STARLAN NETWORK with a Network Access Unit (NAU),
although at lower speed.(The NAU is a CP mounted in STARLAN NETWORK
workstations that permits access to other workstations and/or servers in the
network.) Data transmission through the STARLAN CP is limited to a maximum of
9,600 bps. This is much less than the 1 million bps transmission rate between
workstations/servers on a STARLAN NETWORK.
Applications that require frequent and lengthy transfers of data over the Local Area
Network (LAN) will appear slow.Applications should be designed/configured to run
the executable program locally (on the PC) and to access data from the file server on
the LAN. ACCESS is recommended primarily for shared file and printer access.
Applications should be copied to the user’s (local) disk before they are run.
This program also permits STARLAN NETWORK access for remote PCs if the
System 25 is equipped with a Pooled Modem CP (TN758) or external modem pool.
Remote PCs can dial the STARLAN CP through a modem using either the Direct
Group Calling (DGC) feature or Direct Inward Dialing (DID) trunks to obtain a
connection through System 25 to the STARLAN NETWORK.
