Rules for Dialing

0-9: Numbers to be dialed.

ABCD: Characters to be dialed. (Tone dialing only - used for special control on some phone systems.)

E: Dial the country code.

F: Dial the area code (city code).

G: Dial the local phone number.

H: Dial the card number.

*,#: Characters to be dialed (tone dialing only).

T: Subsequent numbers are to be tone dialed.

For example, the MCI via 1-800-674-7000 calling card has the following rule for long distance calls:

   18006747000,,,,,,TH,,FG
				

This means that the following sequence needs to be dialed in order to place a long distance call with an MCI calling card:

1.	Call 1-800-674-7000.
2.	Wait (6 commas).
3.	Dial next numbers as tone.
4.	Dial the calling card number.
5.	Wait (2 commas).
6.	Dial the area code.
