							Station-to-Station Message Waiting
Station-to-Station Message Waiting
Description
This feature allows pairs of multiline voice terminal users to signal each other with Message
Waiting (MSG WAIT) buttons and associated green status LEDs at each terminal. When
either user presses the MSG WAIT button, the LEDs light at both stations. This arrangement
enables one user to inform the other user that a message is waiting; it can also be adapted
to other two-way signaling purposes such as “come to my office.”
After the MSG WAIT LEDs have been turned on, they can be turned off by operation of the
button at either terminal. The receiver of a station-to-station message should normally turn
off the LEDs as soon as the message is understood so that the link is restored to an idle
condition and is ready for use again.
No talking path or audible alerting is associated with this feature.
Considerations
This feature is functionally similar to, but separate from, the Coverage Message Waiting and
Attendant Message Waiting features.
A station can be a member of more than one Station-to-Station Message Waiting pair, but
must have a separate button for each pair.
This feature is not associated with the built-in MESSAGE (or MSG) indicators of many
System 25 voice terminals.It lights only the LEDs of the feature buttons assigned to
Station-to-Station Message Waiting.
Administration Requirements
Voice Terminal Port:
l For each pair of stations that are to share this feature, assign a MSG WAIT button
with associated status LED at each station.
Note:MSG WAIT buttons always assigned to pairs of stations for use only
between the two stations. If station A needs to signal stations B and
C, station A must have a separate MSG WAIT button for each.

							FEATURES AND SERVICES
System Administration
Description
The software that controls System 25 operation consists of tables located in system memory.
These tables contain data associated with:
l Trunk, Station, and Auxiliary Equipment Ports
l System Parameters
l Direct Group Calling Groups
l Toll Calls Allowed Lists
l Peripheral Equipment Data Communications Parameters
l Automatic Route Selection.
Collectively, these software tables are referred to as translations. The system comes
equipped with default translations data; when full-default cold started, the default translations
are copied into translation memory.
System Administration is the process of managing the translations by making changes to
modify system operation to meet customer requirements.
The System 25 Implementation Manual describes how a system can be configured to meet
specific customer needs.Information about a desired configuration is recorded on a set of
forms that are used when entering the initial system translations (i.e., initializing the system).
These forms are filed in the Administration Records Binder and provide the basis for on-
going record keeping.Modification of initial assignments can be made to meet changing
customer needs.
The system provides an EIA RS-232 interface to a System Administration Terminal (SAT), the
primary means of entering and modifying translations.
System 25 administration consists of:
l Centralized Administration: Configuration of the system and assignment of feature-
related parameters, including assignment of feature buttons on voice terminals.
Centralized Administration is performed via the SAT.
l Advanced Administration: The Advanced Administration Software (AAS) package is
a major improvement in system management. It provides the System Administrator a
user-friendly, powerful tool for accurately and quickly making changes in voice/data
terminal assignments, coverage, access codes, and other system functions such as
ARS.
Two sets of software are available for Advanced Administration. One set operates
on a PC6300 (with 640K RAM) and provides an alternative to use of the SAT input
terminal. The other runs on the Master Controller (UNIX PC) as part of the
“Integrated Solution.”

							System Administration
A main menu gives the user ready access for these tasks:
— Adding/changing/removing voice station assignments
— Adding/removing users to and from coverage groups
— Saving translations.
A significant advantage of the AAS package is that it can be used either at the same
location or can be used remotely via a dial-up connection.
Considerations
The default system administration password (systemx5) can be changed through an
administration item.Note, however, that a system warm start or cold start will reset the
password to this default.
Hardware Requirements
The System Administration Terminal (SAT) is a Model 703 Data Terminal (see Figure 2-56). It
is a general purpose asynchronous full duplex printing data terminal with a RS-232 interface
for data entry and retrieval.It provides a paper record of all transactions. When located
within 50 feet of the system cabinets, it can be directly connected to channel 1 on the
ZTN130 CPU/MEM (Call Processing Unit/Memory) CP. Either on-premises or off-premises
access to the administration port is supported. The terminal operates at a speed of 1200
bps (1200 baud).
Administration port parameters are as follows:
l No parity; bit is set to zero.
l 1 start bit, 1 stop bit, and 7 data bits.
l Autobaud is invoked when carriage return is pressed (300 or 1200).
l DTR (data terminal ready) required from terminal.
l RTS (ready to send) and CTS (clear to send) not required.
l No flow control.
The Model 703 requires 115V ac 60-hertz commercial power from a 3-wire grounded outlet.
The terminal should be located on a flat surface such as a desk or table top. It is
approximately 12 inches wide, 9 inches long, and 3 inches high.

							FEATURES AND SERVICES
The Model 703 keyboard generates ASCII codes.The terminal produces two audible tones
to indicate the completion of activities.
l Short Tone—A tone of less than one half-second indicates the normal termination of
an operation
l Long Tone—A one-second tone indicates that an error or an abnormal operating
condition has been detected.
The Model 703 SAT Supplement contains a complete set of operating instructions for the
Model 703 Data Terminal. This document may be of use to customers who want to use the
terminal for other purposes in addition to system administration. All the information needed
to use the terminal as a SAT is included in the R3 Administration Manual.
The SAT can be connected to the system cabinets in several different ways:
l A direct connection within 50 feet when sharing the same AC outlet as the system
cabinets
l A direct on-premises connection at a distance greater than 50 feet from the system
cabinets
l A direct off-premises connection via the Central Office (OPS or CO trunk)
l An on-premises switched connection
l An off-premises switched connection.
Maximum cabling distances from the system cabinets are provided in Section 5, “Technical
Specifications.”
Installation details are provided in the System 25 Installation and Maintenance Manual.
The SAT may also be provided by the customer. It must be a RS-232 compatible terminal
that has a 25-pin connector providing signal on DTR (pin 20). In addition, it should have the
following characteristics:
Display: The minimum display size is 16 lines by 80 columns. The port provides both
carriage return and line feed characters to position the cursor at the start of the next line.
Destructive scrolling is also expected (new lines added at the bottom of the screen and top-
most lines disappear). Full duplex operation is required. Alphabetic ASCII characters in both
upper-case and lower-case will be sent to the SAT, along with ASCII numerals and some
basic ASCII symbols.The device used must be capable of displaying ASCII alphabetic
characters when either upper-case or lower-case characters are received. However, upper-
to-lower case mapping (or vice-versa) for display is acceptable since no meaning is
associated with case.
Keyboard: The administration port requires ASCII alphanumeric characters as well as some
symbol characters.If the keyboard generates only upper-case or only lower-case alphabetic
characters the administration port will respond appropriately, since upper and lower case
input is considered identical.The SAT should be capable of sending the following ASCII
Characters.
