5.8 Digit map
A digit map is used to control how the ONT or MDU processes dialed digits for a
voice service.
Besides simple collection of the digits of a phone number, it allows for ONT or MDU
internal handling of special dialed sequences like 911 and service codes. The ONT
utilizes the configured digit map at call origination, or in some cases after flash-hook.
In SIP mode 1, there is no digit collection by the ONT after flash-hook. In SIP mode
2, digit collection is usually started after a mid-call flash-hook. In all other cases
digits are simply passed in-band in the voice path, either as tones or as RFC 2833
packets. The digit map also allows for these subscriber interaction functions:
• timeout of digit collection
• termination of digit collection
• output of recall dial tone or normal dial tone
When digit collection is started the ONT digit map library (DML) software is
initialized with timers and the configured digit map string. The DML builds a “tree”
with branches for each possible matching path possible in the digit map string from
left to right. As each digit is input:
1 The tree is traversed using the digits entered so far until a matching pattern is
found.
local_country_code Specifies the display of the
calling party number. The ONT
removes the local country code
from the received phone number
only when the enable_etsi
parameter is configured as false
and the length of the received
phone number is greater than or
equal to 10+ x, where x is the
length of country code. The
default is an empty string. When
the default is an empty string,
then the country_code value is
used.
