Synchronous Call Control Menu
Introduction
The Call Control menu is used only for synchronous circuit switched data calls. The system
bypasses this function entirely if the 7500 is not configured for synchronous circuit switched data
operation. To make data calls when the 7500 operates as asynchronous DCE, you must use the
procedure described in CHAPTER 5: ASYNCHRONOUS DCE CONFIGURATION.
The Call Control menu can include the following items:
Dial? — Dial a stored or unstored number.
Store Number? — Store up to three 15-digit numbers.
End Call? — End an active data call.
When dialing and storing numbers only digits 0-9, *, #, and P (for pause) may be entered in a
dialing string.
The display returns to the (Home) display after a data call is dialed or ended.
When you enter the Call Control menu, the choices you will be given depend on the current status
of your 7500. If you have no call in progress, your choices will be to dial a number or to store a
number. If you have a call in progress, your choices will be to end the call or store a number. Figure 8
shows the Call Control options. The following paragraphs outline the steps you will use to place and
end calls and to store memory numbers.
Placing and Ending Synchronous Data Calls
As Figure 8 indicates, [ DIAL? ] is one of the items in the Call Control menu. Once you select [ DIAL? ],
you must then indicate the number you want to dial. You can select either:
A number previously stored in memory, or
A number that has not been stored.
The following paragraphs describe these menu choices.
