EXCEPTION TABLES PROGIMMMING 
750.1 INTRODUCTION 
Pr0grammin.g Steps 
The 4096 Hybrid Key Telephone System offers 
a flexible means of applying toll restriction to 
stations or individuals. Dialing privileges (or 
toll restriction) is determined through assign- 
ment of station and CO line Class Of Servfce 
(COS). Several types of restriction can be de- 
rived simply by programmin g cos assign- 
ments and CO tie access to stations. This 
may, in some cases, be all that is necessary. 
However, when a more complex or specific type 
of restriction is desired the system offers two 
allow and two deny tables along with four 
special tables. These tables can be pro- 
grammed in a variety of ways to handle appli- 
cations that are straight forward or 
applications that require a more complex ar- 
rangement. 
The allow and deny tables are assigned to 
stations based on their station Class of Service 
(COS) assignment. The Station (COSI interacts 
with CO Line COS assignments to provide 
several di!Terent types of dialtng prklleges (Re- 
fer to CO/Station COS matrix below). 
The Allow and Deny tables allow entries of 
either general or specifk allow and deny codes 
such as allowing all [l-800] type calls, and/or 
denying all Ill+ or (01~ calls. The allow and deny tables allow a maximum of eight digits to 
be entered as allow or deny digits. This allows 
for entry of certain area codes or of&e codes 
or a combination of area code plus office code 
that can specifically be allowed or denied. For 
example the code [l 555-12121 may be entered 
in the deny table to deny local toll Information 
calls. Each allow table contains twenty (20) 
bins for entry of allow codes. ‘Ihe deny tables 
allow for ten (10) entries of deny codes. in each 
table. 
The following rules should be remembered 
when setting up the Al.Iow/Deny tables Prefer 
to Table 750- 1). 
1. 
2. 
3. 
4. If both tables (allow and deny) have no 
entries, no restriction IS applied. 
If entries are made in the allow table and 
only there. then only those numbers are 
allowed. All other dialing is denied. 
If entries are made in the deny table and 
only there. then only those numbers are 
denied. All other dialing is allowed. 
If there are entries in both allow and deny 
tables, the allow table is searched first and 
if amatch is found, it Is allowed. Ifa match 
is not found, the deny table is searched 
and if a match is found there, the call is 
denied. lf the number does not match an 
entry in either table. it is allowed.

TABLE TABLE 
A special ‘Don’t Care” (‘D’) character may be 
entered as a digit to either allow or deny any 
digit dialed in that digit sequence. For example 
a code [ 1 ‘D” 01 and [l ‘D” 11 may be entered 
tn the deny table whtch would allow local long 
distance calls (numbers dialed with a 1 fol- 
lowed by a seven digit local number). but would 
deny long distance calls (numbers dialed with 
a 1 followed by an area code). 
The 4096 system also offers four (4) special 
tables that can be referenced from wlthln the 
two aIlow tables. Three of the special tables 
can be assigned to specific area codes that 
require further toll restriction definition. The 
fourth special table is reserved for use as a 
home area code table (numbers withln the 
same area code as the site where the system is 
fnstaJled). l%is provides expanded ability to 
apply toll restriction on numbers that are di- 
aled within an area code. Each special table 
will allow up to (800) entries (200-999). This 
offers the ability to allow every office code on 
an individual basis 
750.2 RELATED ITEMS TO TOLC RE- 
STRICTION 
A CO/PBXLines 
When CO lines are marked as PEN lines (Refer 
to CO line programming Sec. 720) the system 
wi.lI first check the PE3X code table (Refer to sec. 
710.17) for a valid match. If the first digits 
dialed do not match the entries in the PEX code table the call is considered an attempt to call 
another PBX extension and no toll restriction 
is applied. If the first digits dialed are found in 
the PEX code table then toll restriction will 
start with the next dfaled digit. 
B. Forced Account Codes 
The system can optionally force the use of 
amount codes on ail restricted calls. When 
forced account codes are enabled (Refer to Sec. 
710.19) an account code must be entered to 
place a call that is otherwise restricted through 
toil restriction. By entering an account code 
the stations effective class of setice becomes 
that equal to class of senlce 1 (unrestrictedl. 
When account codes are forced on a system 
wide basis selected users may be instructed on 
how to enter account codes from any statfon 
and be allowed to dial unrestricted from a 
station that may othexwise be restricted. Use 
of account codes in this manner, as a traveling 
class-of-service, is however not controlled by 
the system. Any station user with knowledge 
of how to enter account codes to override a 
stations tolI restriction will be allowed to do so. 
C. SLT DTMY Receivers 
When single line telephones are con.ne&d to 
the 4096 system and toll restriction is enabled 
the system DTMF receivers located on the APL 
board will monitor the call for a programmed 
period of time (Refer to Sec. 710.35, SLT Re- 
ceiver Timer). 
WhiIe the DTMF receiver is 
monitoring the digits being dialed. by a single 
line telephone, it is considered busy and not 
available for monitoring another SLT attempt- 
ing to dial When all DTMF receivers are busy, 
an SLT attempting to go off-hook will not re- 
ceive dial tone until a receiver is available. The 
system has up to six (6) DTMF receivers (two 
(2) standard on the APL and four (4) optional 
on the SLU) for monitoring SLT dialing. If a 
system has heavy SLT usage toll restriction 
may inhibit dialtng by SLT stations. Two op- 
tions are available to help alleviate t&s prob- 
lem: 1) shorten the SLT receiver timer&e 
sectton 710.35). This will f+ee up DTTvlF receiv- 
ers faster, however, may not provide the de- 
sired toll restriction for SLT stations: 2) 
Enable LCR and force LCR on SLT stations. 
When the LCR data base is set up the three 
dlglt table allows for entry of the number of 
digits to be expected. When a SLT dials the 
appropriate number of d.igits LCR will release 
the DTMF receiver and then be available for 
another SLT call.

D. LCR VS. Toll Restriction 
LCR is not intended to be an alternative to toll 
restriction nor is toll restriction intended to be 
a a&mate to LCR 
In fact they both work best 
when programmed together. Toll restriction 
provides the dk&ng privileges that stations are 
allowed and LCR provides the muting of calls 
onto the proper type of lines. LCR can enhance 
toll restriction in that LCR provides a ‘Store 
and Forward’ operation that allows the system 
to zanalpe the digits being dialed before a trunk 
is seized. This prevents users from by-passing 
toll restriction by taking advantage of the time 
it takes for a central offfce line to provide dial 
tone. Because of this it is recommended that 
LCR be considered when toll restrfction is de- 
sired.

All toll tables have been conveniently placed 
under one program code to allow entry of aJl 
toll restriction data. When entering toll infor- 
mation the buttons on the phone will be 
mapped as follows: 
When the system searches the allow and deny 
tables, the entries are looked at starting at Bin 
01 and proceeding sequentially through the 
table to the last bin. In additionThe allow table 
is always searched before looking at the deny 
table. Therefore the order of entry is impor- 
tant. Entries that are specific (Le. [ 1 7161) 
should be placed ahead of entries that are more 
general (usually include ‘Don’t Care” digits i.e. 
(1 ‘D” 11). 
Once a match is found, in the allow table, that 
references a special table the number dialed 
will be checked for an allowed code in the 
special table. If a match is not found in the 
special table the system will conttnue to check 
for a match in the next allow or deny table that 
is to be checked. The system will not return to 
the table that sent the call to the special table.

Then make note as to how the numbers 
will be dialed when dialing numbers to this 
area code (i.e. with a leading digit [ 11 or no 
leading digit [l]). The entry into the allow 
table would be entered as follows: 
Leading digit 111 - BB 1 XXX DDD (S) or

Where: 
BB = Bin number (recommended 17- 19)

Allow Table - Each Allow table contains twenty 
(20) bin numbers. Each bin number may be 
up to eight (8) digits in length including (Don’t 
Care) dfgits and (Search Special Table) com- 
mands. Entries into the allow table represent 
exceptions to numbers or codes that are to be 
allowed only if they would othenvise be re- 
stricted by an entry in the deny table. For 
example if I1 555 12121 is to be allowed but 
[1+1 numbers are denied. by an entry ‘into the 
deny table, then [l 555 12121 should be en- 
tered into the allow table as an allowed num- 
ber. 
Allow table A is referenced and searched 
first (before the deny table A) when Station 
COS is 2 and CO line COS is either 1 or 2. 
Allow table B is referenced and looked at 
first (before the deny table B) when Station 
COS is 3 and CO line COS is either 1 or 3. 
When station COS is 4 and CO Une COS 
is 1 both allow tables are looked at first 
Wow table A first then allow table B) then

Don’t Care digits specify that the system 
should consider any digit dialed in that posi- 
tion as a match. Don’t Care digits should not 
be entered as the last digit in an entry, as this 
would be an unnecessary or meaningless com- 
mand. 
Searcli Special Table commands must be en-
