Programming Password Protection

No one can enter a programming mode to reprogram the system without first entering a

password. The system provides two different entry levels for programming and allows

for a different password for each entry. The two programming entry levels are the

installer level and the administrator level. Programmers can enter the installer level, using

the installer password, to perform all programming functions including major changes

such as master clearing and line type programming. They can enter the administrator

level, using the administrator password, to perform most programming functions except

those major changes just mentioned. Programmers can use the VDT programming

method to change the passwords from their default values as needed to provide security

against unauthorized program entries. They can do this when the system is initially

installed and programmed, or at any later time as needed. Additionally, programmers can

construct a password that will prevent all COS programming entry from station 10.

Customized passwords can be alpha-numeric or numeric only (no spaces allowed) and

must contain six characters. To retain the ability to enter programming from station 10,

programmers must maintain the I✳nnn✳ format in the VDT password and enter only

numbers in the nnn entry; however, they must not enter a zero for the leading n. Once

customized, a password remains customized. Neither default nor master clear will erase

it. Programmers must use the new password to gain entry into the system for future

programming tasks. It is very important that someone keep a hard copy of the customized

password since it provides the only entry to system COS programming through either the

VDT or station 10. If no one can remember the customized password, the manufacturer

can provide emergency entry but there is a charge for this service. Otherwise, the installer

must disconnect all AC power and any battery back up equipment, wait at for an

extended period of time (up to several weeks) for the internal memory protection to

completely discharge, and reprogram the system using the default password to gain entry.

Pulse/Tone Switchable

The programmer can program the system on a per line basis using the line class of

service programming to allow the stations to switch from pulse to DTMF type dialing as

needed. Alternately, she or he can program the system to only allow tone dialing.
