C.Extra Code Add (ETR CODE ADD)

In some applications it may be necessary to add an Extra Code in front of the number to be dialed. When ADD is programmed, the digits in the specified Extra Code Table will be added. NO is programmed when no extra codes are to be used.

D.Prefu Add/Check (PFX ADD CHK)

When the prefix 1 is needed in front of the number to be dialed, regardless of the office code dialed, then YES should be programmed. When prefix 1 is not required, NO should be programmed. If whether or not the prefix 1 is to be added depends on the office code dialed, then CHK should be programmed. This will perform a check of this specified office code table and either add the prefix 1 or not depending on the information provided for the office code which was dialed.

NOTE: When the system resides in a l+ Dialing area, prefix ADD/CHECK must be set to add as LCR ALWAYS STRIPS THE 1 WHEN IT IS DIALED BY THE USER.

E.Service Area Check (SVC AREA CHK)

If service on the selected route is available for all office codes, then NO should be programmed and NO Service Area Check will be performed. When CHK is programmed, the

specified office code table will be checked for information on whether or not service to the

office code dialed is provided by the selected . route. If service is provided, the call will be completed. If service is not provided, then the

next route table in the Route Advance Table will be selected.

Extra Code Tables (ETR CODE TBL)

Sixteen Extra Code Tables (00-15) are provided. Each Extra Code Table can contain a maximum of

24 digits. When EXTRA CODE ADD is programmed for CHK within a Route Table, the specified Extra Code Table will be referenced and the extra code it contains will be added in front of the number to be dialed.

Office Code Tables (OFC CODE TBL)

One hundred twenty eight Office Code Tables (000-127) are provided. Each Office Code Table contains all the possible office codes and a flag bit for each office code which can be set either as 0 or 1. The meaning of the setting of each flag bit depends on whether the Office Code Table is referenced by the Prefix Add/Check or Service Area Check parameters of a given Route Table.

0 = The prefix 1 is to be added to the number to be dialed when this office code is dialed.
