be effected. If the other station does not have access to the incoming line, transfer can still take place using the system transfer feature. For a screened transfer, a call is transferred to another station with a pre-transfer announcement by the transferring patty. Transferring calls is accomplished with the TRANSCONF button. Also refer to the discussion titled: Call Transfer- Unscreened.

CALL TRANSFER - UNSCREENED,

An active call can be transferred to another station without being announced. The transferred call will camp-on to the other station where it will ring and await an answer. The call will automatically ring back to the transferring station after a programmable recall period. There is no limit as to how many calls can be camped onto another station. A transferred call will only ring if the station is idle. The system class of service programming determines the recall time for an unanswered transferred call.

CALL WAITING TONE

The call waiting tone may be signalled to a busy station to indicate that another station or the attendant wants to contact the busy station. A special code is dialed to activate the tone.

CALLING STATION

IDENTIFICATION ON BLF

If the station number of a calling station has been programmed into the direct station select/busy lamp field (DSS/BLF) of a called station, the caller will be identified by flashing at the corresponding BLF light. The lights also indicate the status of the DSS telephones: dark = idle, steady-on = in use, flash = calling (or ringing when station monitoring is enabled), and flutter = call back request (if feature is available. No class of service programming is required for this feature. Also refer to the discussions titled: Programmable DSS/BL F and Call Messaging.

CLASS OF SERVICE PROGRAMMING

(FROM MAIN STATION)

Class of service (COS) programming is used by the installer to configure and assign all system, line, station, and special purpose operating features. The installer enters COS programming by dialing an access code over the intercom line. System administrators can enter COS programming with another code to reprogram any system, station, or special purpose operating feature that may require change at a later date. Line reprogramming abifiiy is not available through system administration programming. The system attendant can reprogram certain system-wide features that require periodic change by entering COS programming with another

code provided for this purpose. The station user can program individual stations for speed dial, autodial and direct station selection (DSS) by entering COS with a code provided for that purpose. Thus, COS programming is arranged with a hierarchical order from the highest (the installer) to the lowest (the station user) level wfth a higher level programmer having the ability to do anything a lower level programmer can do without exiting a current programming mode. However, only the station user can program the speed dial and autodial locations at telephone.

All class of service (COS) programming is performed from station 10 or 12. Any station and console combination will function in this mode and provide visual feedback with the LED associated with the programming button. By employing an LCD speakerphone, however, the programmer will have the benefit of display prompts and verifications to simplify and clarify the programming procedures. Class of service programming access is as follows:

•Installer dials: ITCM % # 7 4 6 +K

•Administrator dials: ITCM +++ # 2 3 6 +I+ • Attendant dials: ITCM % # 0

• User dials: ITCM +# +

Class of service programming can be performed using instructions provided in Chapter 4, Sections 2,3 and 4.

CLASS OF SERVICE PROGRAMMING

(VIDEO DISPLAY TERMINAL)

An asynchronous, serial data terminal with an RS-232 interface can be used to effect class of service programming through menu-driven procedures. VDT programming provides a menu-driven approach to programming as discussed in Chapter 4, Section 5.

CLASS OF SERVICE

PROGRAM PRINTOUT

Connection terminals are provided to interface an RS-232 compatible, asynchronous serial data printer to the system. The connected printer will provide a printout of class of service and toll restriction records. The data prlnter service class of service programming determines the nature and extent of each requested printout. The system class of service programming specifies the bit-length and baud rate of the data.

COMMON AUDIBLE

RINGER INTERFACE

Connections are available at the wmmon equipment that provides “dry-contact” relay closures whenever an incoming line rings. These contact closures track the ringing pattern and can be used to control an external
