Comdial Dsu II Digital Telephone System Instructions Manual

							This makes the button designations match the A and B designations called for in this system
programming manual.
When button mapping using a telephone different from the telephones being programmed
(cross-model button mapping), you may need either a programming overlay or Table 3–1
depending on the type of telephone installed at the programming port.
If all system telephones are the same type, when you press a button at the programming station,
you select the same button on the telephone that you are mapping. No overlay or conversion
chart is needed.
When you mix telephones on the same system and you are cross-model button mapping, you
will need either an overlay or the conversion chart. The overlay works best when you are using
anImpacttelephone to button map an Impression or DigiTech telephone. The chart is more
convenient when you are using a DigiTech or Impression telephone to button map anImpact
telephone. In either case, when you map a line to a selected button, it is best if you choose the
line by dialing its code rather than by pressing a button on the programming station to represent
it. To choose lines 1 through 24, you must dial01through024.
The following examples explain when you need to use conversions.
·To select buttonL21for reprogramming on anImpacttelephone using anotherImpact
telephone at station 10 for programming, press buttonL21on the station 10 telephone. (No
conversion is required in this example.)
·To select buttonB5for reprogramming on an Impression or DigiTech telephone while
using anImpacttelephone for programming, press the button designated asB5by the
programming overlay on theImpacttelephone at station 10 (this is actually L21 but the
overlay did the conversion for you).
·To select buttonL21for reprogramming on anImpacttelephone while using an Impression
or DigiTech telephone for programming, press buttonB5on the Impression or DigiTech
telephone at station 10. (You use the conversion chart to convert the B5 button to an L21
button.)

							3.2.4 Using A VDT To Program The System
You can perform class of service programming using a Video Display Terminal (VDT) with an
RS-232 compatible, serial interface. (You can use a personal computer running a
communications software program in place of the VDT if you wish.) VDT programming is
completely menu driven and easy to follow. It is arranged somewhat differently from station port
programming categories to facilitate menu usage.
3.2.5 Using Block Programming
You can program a group of lines or stations to have the same configuration as one that you have
already programmed. This block programming feature eliminates the need to individually
program every line or station that requires the same configuration.
3.2.6 Master Clearing The System
After you have completely installed a telephone system for the first time or if a system that you
previously installed has been turned off and placed out of service for a period of time (several
weeks, for example), perform a master clear programming procedure before placing it into
service. If you plan to perform a master clear procedure, perform it first before performing any
other programming procedure. The master clear procedure clears all memory locations of any
unwanted data that may be stored there. Master clearing also clears any previously programmed
data, such as autodial numbers and defaults all class-of-service conditions. Therefore, never
perform a master clear procedure on an existing installed system unless data loss and COS
default are acceptable. Refer to the information provided in the procedure titled Master Clear for
programming details.
3.2.7 Using Programming Overlays
The literature package with the system includes a programming overlay for use in identifying the
buttons required for programming. The overlay fits over the buttons of the programming station.
A full size copy of available programming overlays is also included at the end of Chapter 4. The
overlays correspond to the programming steps listed for each feature, so when you are directed
to press B1, for example, the overlay details which button is B1 for your telephone.
If you are programming the system from a VDT, it is best to allow the telephones to identify
themselves to the system before you button map them. When you do this, the VDT presents the
proper button designations in its prompt and you will not need an overlay or conversion chart.
The system queries you to designate the telephone type for unoccupied station ports. Upon your
response, the system presents the proper button designations in the prompts for these ports.

							3.3 Master Clearing and Defaulting The System
You can return the entire programming configuration to the factory settings using the master clear
procedure. You can also return the individual system, line, and station class of service configurations to
their factory settings using the system, line, and station default procedures. The operating parameters and
class of service values provided by the factory settings will provide satisfactory performance in a broad
range of site applications.
CAUTION
Not only does the master clear procedure return ALL programmed variables to a
known state of operation it also clears all currently stored autodial and speed dial
numbers.

them to the lines. You need only to assign them the stations to put them into effect. The
preprogrammed values are as follows:
Table 1 (deny)Table 2 (allow)
Entry 1 = 1 Entry 1= 1800
Entry 2 = 976 Entry 2 = 911
Entry 3 = 411
Entry 4 = 0
These values will provide satisfactory system performance in a broad range of site
applications; however, they can be changed as needed to meet different toll restriction
needs.

							3.3.7 Programming Password Protection
Description:The system provides two different entry levels for programming and  allows for a
different password for each entry. You must use the VDT programming method to
change them as needed to provide security against unauthorized program entries. The two
programming entry levels are the installer level and the administrator level. You enter the
installer level, using the installer password, to perform all programming functions
including major changes such as master clearing or line type programming.
Administrators enter the administrator level, using the administrator password, to
perform most programming functions except those major changes just mentioned. You
can make the two passwords different to limit access to either programming level to only
certain special or authorized people. Additionally, you can construct a password that will
prevent all COS programming entry from station 10.
Default Passwords
The default passwords are detailed in the following list:
VDT Installer ISnnnS(nnn = 746)
VDT Administrator ISnnnS(nnn = 236)
Station 10 Installer INTERCOMS#nnnS(nnn = 746)
Station 10 Administrator INTERCOMS#nnnS(nnn = 236)
Customized Passwords
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,
you must maintain the ISnnnSformat in the VDT password and you must enter only
numbers in the nnn entry; however, you must not enter a zero for the leadingn.
Once you customize a password, it remains customized and you must use the new
password to gain entry into the system for future programming tasks. Neither default nor
master clear will erase the customized password. It is very important that you 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, Comdial’s Technical Services Department can provide emergency
entrybut it charges a fee for this service. Otherwise, you must disconnect all AC power
and any battery back-up equipment, wait 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.
NOTE:Password protection programming is a Video Display Terminal feature only. You can not
customize a password using station 10 programming entry.

							3.4 System Features
Configuring the system means that you are setting the parameters that will be true system-wide. You
should make a record in Chapter 4 of all programming decisions that you make—it will help you keep
track of what you have done and will help you troubleshoot any problem that might arise later.
NOTE:A lighted LED next to the programming button for the selection indicates the current
configuration. When a single button provides a toggle (on/off) action, the lighted LED
indicates the active feature.
The first step in any programming sequence is to enter the base level.  Once in this mode, you can dial the
feature code for any desired configuration. Enter the base level with the following procedure:
pressINTERCOMthen dialS# 746S. When you want to end the programming, press theSPEAKER
button to end the programming procedure and return the system to normal operation.
3.4.1 Automatic Station Relocation
Description:With this feature, the system will automatically recognize a particular station should that
station be re-located to a different station port. The system will supply the same COS
parameters at this new port as was programmed for the station at the original port. This
feature allows users to relocate their telephone from one station port location to another
yet retain their original telephone features.
NOTE:If you turn this feature on, be sure to make the station users understand that
their telephone parameters could change if they trade telephones from port to
port. If you want automatic relocation to take place, do nothing and wait for
the light to turn off on its own, or press theHOLDbutton to immediately
accept the relocation. If you do not want automatic relocation to take place,
press the#button while the message waiting light is flashing.
