Comdial Dsu II Digital Telephone System Instructions Manual

							2.15 Checking The System Installation
The system operating features are set to default conditions at initial power-up. These conditions
provide a basic operating system with a known set of parameters, and you should check out the
system with the default conditions in place. At any time while the system is operating, you can
reset default conditions from station port 10 or 12 following the instructions provided in chapter
3,Programming.
2.15.1 Checking The Resistance
Measure the resistance at the station connector blocks under the following conditions.
·AC power cord disconnected from electrical outlet.
·Common equipment connected to station connector blocks.
·Stations wired and wiring punched down on blocks.
·Bridging clips removed from blocks to isolate stations from common equipment.
Measure the resistance of each installed station and wiring from the station side of the connector
blocks. Resistance values will vary with cable length and station type but should be within the
following limits:
·Greater than 700 KW
2.15.2 Checking The Voltage
Make the following voltage measurements at the station connector blocks under the following
conditions:
·Bridging clips installed
·AC power connected to the common equipment
Measure the voltage across the signal pair. The measured voltage for proprietary telephones must
be within the following limits:
·28–36 VDC
NOTE: Refer to Section 2.14.2 for information on testing industry-standard telephones
connected through the JM008 expansion module.

							2.15.3 Checking The General Operating Conditions
1. Check the green light emitting diode (LED) system status indicator. Be sure that it is on
steady. If it is off or flashing, refer to the paragraph titledChecking the System Status
Indicator.
2. Refer to the user’s guide for operating information and perform a general operational test of
the system by exercising the features from station port 10 or 11. Operational parameters are
per the system default conditions as detailed in Chapter 4 until class of service programming
is performed.
3. Once the basic system is verified as operational, perform the class of service programming as
described in Chapter 3.
2.16 Isolating Failures
Section 2.17 will help you to find and identify problems that might occur in the digital telephone
system.
2.16.1 Checking The System Status Indicator
A green LED located on the common equipment cabinet is the system status indicator. This
indicator light comes on when power is supplied to the system. If the indicator flashes after
power up, it signals that the processor has failed or that the software is not operating. Unplug and
reconnect the AC power to the power supply and observe the LED indication. If it still shows a
flashing indication, equipment replacement may be necessary.
2.16.2 Testing The Stations
To test the multiline stations for proper operation:
1. Disconnect line cord at station base then reconnect it.
2.
On DigiTech telephones, press and hold theMUTEbutton.
OnImpactand Impression telephones, press and hold1on the keypad.
Station will automatically perform self test routine.
3. Release test button as soon as test begins. Sequence of test is as follows:
a. indicators will light in sequence,
b. ringer will sound—be sure volume is set to low or high,
c. indicators and ringer will then turn off at the same time.
4. Replace any station that does not pass the self test.

							2.17 Loading And Up-Grading The System Software
The DSU II contains flash memory that you load with operating software when you install the
system and later re-load with software up-grades as they become available.
The operating software package consists of three parts: The boot-loader EPROMs that is
factory-installed as part of the system, and the software key and software disks that you order
separately. The software disks include the boot loader interface disk and the operating software
disks.
2.17.1 Introducing The Software Key
The software key is a hardware device to un-lock the DSU II so it can accept the system
operating software. Factory technicians program and initialize the software key, and make it
available in several different configurations.
The configurations are as listed below:
DSUII–SW01
DSUII–SW05
DSUII–SW10
DSUII–SW25
The configurations control the number of times that you can use a key to load or up-grade
operating software into a system; however, it does not matter which DSU II system you load.
(For example, with a DSUII–SW01 key, you can load any DSU II system one time; however,
with the DSUII–SW25, you can load or up-grade one system 25 times or load 25 different
systems one time—your choice.)

							2.17.2 Introducing The Software Disks
There are several standard 3.5-inch magnetic diskettes for each software part number. This group
of diskettes include the boot loader interface and the system operating software. You place these
diskettes (commonly referred to as floppy disks), into your personal computer (PC) in a certain
order just as you would any set of program disks.
CAUTION
The system operating software is unique for each of the three system sizes. Be sure that you
load the correct system software for the size system that you are installing.

Installing The System Operating Software
CAUTION
In this software loading sequence, the system will prompt you to save the class of service data
base. ALWAYS SAVE THE DATA BASE FIRST before you proceed with the software load.
Saving the data base first ensures that you will have it available should something go wrong
during the software loading procedure. Later, after you have finished loading the system
software, master clear the system and reload the data base that you saved before you loaded
the software.
Saving The Class Of Service Data Base(Using An XMODEM-Type Communications Program)
Use the PC and an XMODEM-type communications software program to save the DSU II
system’s class of service data base before you load the software. The following procedure
illustrates a typical data base down-load usingPROCOMM(produced by Datastorm
Technologies Inc.). Other software programs are also available that you can use for this purpose.
1. When the PC display prompts for a password, typeIS746Sor the current system password
and pressRETURN(This causes main COS programming menu to be displayed).
2. From main menu, make all selections necessary to perform class of service programming
then return to the main menu.
3. From main menu, press1andRETURN(This causes system COS programming menu to be
displayed).

							4. From the system menu, press4andRETURN(This causes load/save menu to be
displayed.) From load/save menu, you can down-load the COS data base to your PC
(usually to some temporary location on your hard drive).
To down-load the data base,
(a) press1andRETURN,
(b)  pressPAGE DOWN,
(c) press1to choose XMODEM protocol,
(d)  type destination file name for the down-loaded data base—include destination
drive (for example, C:\ cust.001)
(e) pressRETURN. The data base automatically down-loads to the destination file.
To down-load speed dials and auto dials,
(a) press3andRETURN,
(b)  repeat above steps b–e.
To up-load the data base after you have up-graded the system operation software and
master-cleared the system,
(a) press2thenRETURN
(b)  pressPAGE UP
(c) press1to choose XMODEM protocol
(e) type file name of saved COS data—include source drive if necessary
(f)  pressRETURN. The data base is automatically up-loads to the DSU II system.
To up-load speed dials and auto dials,
(a) press4andRETURN,
(b) repeat above steps b–f.
If the up-load completes properly, the screen displays:Xmodem transfer complete, no errors.
5. Return to the main menu and log off.
