Compare the number of digits sent by the local telephone company to the
number of digits in your system numbering plan. If the number of digits sent by
the local telephone company is fewer than the number of digits in your system
numbering plan, specify that specific digits (1–9999) be added to the digits
sent. This is needed to route the call to the extension numbers in your system.
For example, the local telephone company sends two digits. Your numbering
plan includes extensions numbered from 1200 to 1299. You can specify that the
digits 1 and 2 be added to the digits received from the local telephone
company.
Keep the factory setting of zero digits if the number of digits sent matches your
system numbering plan.
Planning Form Instructions
On Form 3e, under the "Add Digits" heading:
1 . Check "0" if your numbering plan matches the number of digits sent by
the telephone company.
2. Check "Add these digits" to indicate that digits must be added to the
telephone number sent by the telephone company. Write the specific
digits to be added in the space provided.
Select the type of dialing signals sent from the local telephone company. The
choices are rotary (the factory setting) or touch-tone.
Note: You cannot have touch-tone if you selected immediate-start.
Planning Form Instructions
On Form 3e, under the "Signaling" heading:
1. Check "Rotary" to specify the factory-set signal.
2 . Check "Touch-tone" to change the setting.
When outside calls from DID trunks, Remote Access users, or dial-in tie trunks
are made to an unassigned extension number, the system redirects the call to a
backup position, normally the primary operator.
You can change the setting to specify that the caller is given a fast busy signal
to indicate an invalid destination.
This setting applies to both blocks. You cannot specify a different setting for
each block.
