25 Administration Manual.

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.

Procedures for performing Centralized and Advanced Administration are provided in System

25 Adrninistration Manual and System 25 Advanced Administration Manual, respectively.

Hardware Requirements

The System Administration Terminal (SAT) is a Model 703 Data Terminal (see Figure 2-45).It is a general purpose asynchronous full duplex printing data terminal with an 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 ZTN82 or ZTN128 Call Processor 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).

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.

The Model 703 keyboard generates ASCII codes. The terminal produces two audible tones to indicate the completion of activities.

● Short Tone–A tone of less than one half-second indicates the normal termination of an operation

●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 System

The SAT can be connected to the system cabinets in several different ways:

●A direct connection within 50 feet when sharing the same AC outlet as the system cabinets

●A direct on-premises connection at a distance greater than 50 feet from the system cabinets

● A direct off-premises connection via the Central Office (OPS or CO trunk)

● An on-premises switched connection

●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 Test 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
