ATM Option
5.4.15 Delete digits
Defines the duration, in milliseconds, of the contact (or “make”) for each digit that is
dialed using rotary type dialing. The NetPerformer calculates the break value by
subtracting the make value from 100.
For example, the value 34 defines the make/break ratio as 34/66. This value is used in
North America, Belgium, Denmark, U.K., France, Portugal and other countries, and is the
default Pulse Make/Break Ratio. When you rotate the dial to a number and release it, a
break/contact sequence is repeated once for each digit the dial passes as it returns to the
starting position. If, for instance, you dial the number 3, what follows is a 66 ms break, a
34 ms make, a 66 ms break, a 34 ms make, a 66 ms break, then a continuous make (closed
loop).
Telephone equipment manufacturers in other countries have implemented other make/
break ratios. For example, a 40/60 ratio is used in Austria, Germany, Italy, Ireland,
Sweden, Switzerland and some other countries. Configure this by setting the Pulse Make/
Break Ratio to 40. To ensure correct configuration of the Pulse Make/Break Ratio
parameter for your site, contact your local telephone company for the make/break ratio
that is currently in use.
Values: 30 - 50 ms (in increments of 4)
Default: 34 ms

Delete digits atmpvcVoiceDelDigits [atmpvc#] VoiceDelDigits
Specifies the number of leading dial digits (if any) that will be deleted from a dial string
before it is forwarded to the attached voice equipment. When set to 0, no dial digits are
deleted.
This parameter serves to delete the leading dial digits that may be inserted by an attached
PBX. For example, a PBX may insert a “9” prefix in any dial string. If you dial “1234”,
the result would be “91234”. To forward the correct dial string to the remote voice
equipment, the local NetPerformer must be able to delete the first digit of the string. In this
case, you would set the local port’s Delete Digits parameter to 1.
NOTE: This parameter is not required and does not appear on the NetPerformer console
for voice ports associated with an EIC-1MB card that is running Q.SIG
signaling.
Values: 0 - 4
Default: 0
