SAMSUNG DCS
TECHNICAL MANUAL
This system is installed in an area where not all seven digit calls are "free" and a 1 is not required when
dialling other area codes. Area codes all have 0 or 1 as a middle digit.
Customer requirements:
• Class B phones can only dial area codes east of the Mississippi and all CO prefixes in their own area
code.
• Class C phones are allowed to dial 186 out 292 CO prefixes.
• Class D phones are only allowed to dial 57 of the 292 CO prefixes.
• Classes C and D cannot dial outside their own area code.
The large number of entries required to demonstrate this example makes a full listing impractical.
Follow these guidelines:
Class B Programming - List all of the allowed area codes in the allow table and mark each entry for Class B
and enter X0X and X1X in the deny table for Class B. This will deny all area codes not listed in the allow
table.
Class C Programming - Enter X in the deny table to restrict all numbers not listed in the allow table and mark
this entry to apply to Class C. List the 186 allowable CO prefixes in the allow table and mark these entries to
apply to Class C.
Class D Programming - Add a 1 in the Class D column of the X entry to make it apply to Class D. List the 57
allowable CO prefixes in the allow table and mark these entries to apply to Class D. Some or all of these CO
prefixes may already be entered for Class C above. Do not repeat the entry; you only need to add a 1 in the
Class D column to each entry that applies to Class D.
