Table 2d. TOLL.RESTRICTION PROGRAMMING REFERENCE 
HOW TO FILL &JT THE 
TOLL RESTRICTION TABLES 
Determine the types of dialing restrictions which must be 
imposed on the system. Typically, this includes access 
codes which result in toll charges, and certain local 
numbers as desired. 
If the restricted dialing codes will be imposed consistently 
on most 
or all stations in the system, list them on one or two 
entry tables. If a wide variation in the dialing restrictions is 
planned, spread the listings out across several tables. 
Strategically group the listings on the tables so that a list of 
restrictions can be applied to a particular station or 
stations. 
Press a 
q key in place of a particular digit to condense a series of restricted codes into one listing. For example, if 
357, 387, and 397 are to be restricted digits, one entry of 
3 # 7 can be listed to cover them all. 
HOW TO PROGRAM THE

6. 
6. 
_ 
Enter # 1 II and IO I to restrict all 3-digit access codes with a 1 or 0 as a middle digit. 
Designate each table as a 
DENY table or as an ALLOW 
table. All entries on a DENY table are dialing restricted 
entries. All ALLOW table entries allows certain override 
conditions to prevail. A typical example follows: A DENY 
table may contain entries which restricts the dialing of 
1 804 while an ALLOW table may contain entries which do 
not restrict the dialing of 1 &XI. Another typical entry on an 
ALLOW table is a PBX outside line 
access code. This entry 
will allow a toll restricted station to have access to an 
outside line for an unrestricted use. 
Once these tables are completely filled out. enter this 
restriction planning on tables 2b and 2c so that 
the line and 
station programming reference records reflect the planned 
toll restrictions for the system. 
. 
Dial the restricted number from the keypad. 
- maximum of 16 digits allowed. 
-dial 
q for “match anything” digit. 
Select another table entry: repeat step 5. 
-automatic selection of next entry point occurs after 16th 
digit is dialed in preceding entry. 
Make entry for all four table entry points: repeat steps 5 
through 7. 
Select another table: repeat step 3. 
- automatic table selection occurs after 16th digit is dialed 
in 4th entry of preceding table. 
10. Repeat steps 3 through 8 until all desired toll restriction 
tables are created.

CHAPTER 5 
MAINTENANCE 
SECTION 1 
TECHNICAL ASSISTANCE 
AND REPAIR SERVICE 
Should you experience difficulty installing the Model 816 electronic 
key system, if the system fails to operate properly after 
installation, 
or if the system ever requires servicing, call the 
Technical Service staff. They can be reached at 800-431-4345 (in 
Virginia: 804-978-2288) between the hours of 8:00 AM and 4:30 PM 
Eastern time, Monday through Friday. Additional literature is also 
available by calling this number. 
If your KSU or an individual station needs repair, subsequ;;: to the 
warranty period, it may be returned to the manufacturer. 
manufacturer will, at their option, 
either repair the defective 
equipment or replace it with a remanufactured unit. This repair will 
be done for a fixed charge. For information on this charge, 
please 
call or write to the address given below. 
When returning equipment for repair, 
pack it carefully to prevent 
damage. Any damages during shipment will be the responsibility of the 
purchaser. 
prepaid. The equipment should be shipped freight or postage 
SECTION 2 
TROUBLESHOOTING 
FUSE LOCATION 
The KSU is protected against short circuit damage by a fuse located in 
the primary of the AC transformer winding. Fuse FS-1 is a 1 ampl 
25OV, SLO-BLO type fuse. The fuse holder is located near the ton of 
the right side of the KSU cabinet. Always replace this fuse with one 
of the same value and type, otherwise, equipment damage 
could result.

c 
IMI 66-031 ’ 
FAILURE ISOLATION 
The red LED located near the fuse holder 
is the system status 
indicator. This indicator should turn on steady when AC power is 
applied to the KSU. 
If the indicator flashes after power up, it could 
be indicating a processor failure. Unplug and reconnect the AC power 
to the KSU and observe the LED indication. 
If it still shows a. 
flashing indication, refer to Figure 9. 
Exercise the station self test feature as follows: 
1. Disconnect the line cord at the station base. 
IMPORTANT NOTE 
THE ADJACENT ODD OR EVEN STATION WILL BE DISABLED DURING THE 
TIME THAT THE STATION LINE CORD IS BEING DISCONNECTED OR 
RECONNECTED. 
2. 
Press and hold the- MUTE key, 
and reconnect the line cord to the 
sta,tion connector. The station will automatically perform a self 
test routine. 
Release the 
MUTE key as soon as the test begins. 
The sequence of the test is as follows: 
i 
a. 
The line select indicators will light in sequence from 1 to 8. 
b. The intercom select indicator will light. 
dc: The speaker indicator will light. 
All indicators will turn off in the same sequence. 
e. 
The ringer will sound - 
Be sure that the ringer volume control 
is set to the medium or high volume setting. 
;i. Replace any station that does not pass the self test. 
Test the DSS/BLF Console for proper lamp-operation per the following 
procedure. 
. 1. Disconnect the console line cord plug from the line. 
2. Press and hold the station. 10 select key while reconnecting the 
line cord plug to the line. 
; c 
I . 
IMPORTANT. NCTE 
THE COMPANION STATION WILL BE DISABLED DURING THE TIME 
THAT THE CONSOLE IS BEING DISCONNECTED AND RECONNECTED.

							Maintenance IMI 66-031 
c 3. Release the station 10 select key, and note that the BLF 
indicators will each turn on in sequence beginning with the 
station 10 indicator. The indicators will then turn off and the 
console will become operational. 
Data Line Pairing 
All stations are even/odd paired on the data lines as shown in Table 
3. Station 10 is paired with station 11, etc. If erratic light 
indications or ring signals occur at a paired station, an open data 
pair at either station may be the fault.. A station with an open data 
line may work properly on a short loop but fail on a long loop. Test 
the station wiring per the checkout procedure given in Chapter 2. 
Overload Pairing 
All stations are paired as shown in Table 3 for overload current 
protection. If a fault occurs which causes more than 300 
ma. of 
current to be drawn, 
the paired stations are disabled by circuit 
r 
action. Disconnect the disabled 
time to isolate the faulty one. stations and reconnect-them one at a

Figure 9 details a failure analysis flow chart to assist a service 
technician in isolating a failure in a defective system. One way to 
isolate a failure is to substitute a known good assembly for a 
suspected one. This is the recommended failure isolation method to 
use with the system. 
Connecting and disconnecting stations to the system does not affect 
the stored station auto/speed dial memory data. This data is stored 
in the KSU memory and not at the individual stations. 
Replacing the 
KSU, however, causes all stored memory to be lost. This includes all 
memory dialing numbers as well as all COS programming data.
