In the first row of the table, the destination pattern specifies a seven-digit string. The first digit
must be a five, and the remaining six digits can be any valid digits. All seven digits must be
entered before the destination pattern is matched.
In the second row, the destination pattern specifies a seven-digit string. The first three digits
must be 555, and the remaining four digits can be any valid digits. All seven digits must be
entered before the destination pattern is matched.
In the third row, the destination pattern specifies a three-digit string. The dialed digits must be
exactly 555. When the user begins to dial the seven-digit number, the destination pattern
matches after the first three digits are entered. The router then stops collecting digits and places
the call. If the call is set up quickly, the answering party at the other end may hear the
remaining four digits as the user finishes dialing the string. After a call is set up, any dual tone
multifrequency (DTMF) tones are sent through the voice path and played out at the other end.
In the last row, the destination pattern specifies a variable-length digit string that is at least
three digits long. The first three digits must be exactly 555, and the remaining digits can be any
valid digits. The “T” tells the router to continue collecting digits until the interdigit timer
expires. The router stops collecting digits when the timer expires, or when the user presses the
pound (#) key.
