7.22 Using E and M Tie Lines

E & M tie line operation is typically used in applications where one group of users often need to call parties located in one or more remote locations. In these applications, your system is directly tied to another similar system at the remote site(s).

If your system has been configured for tie line operation, the procedures you use to place calls, transfer calls, and set up conference calls differ slightly from other types of connections. These procedures are described in this section.

•To make a call on an E & M tie line,

1.Dial the E & M access code that was assigned by the installer, —OR—

if your system has been configured by the installer to use Automatic Route Selection (ARS), dial the ARS access code (9).

2.Wait until you hear a dial tone, then dial the intercom number for the party you wish to reach at the remote site. You will hear a fast busy signal if you dialed an invalid number.

•To transfer a call over an E & M tie line,

1.Answer the incoming call.

2.Press CONF.

3.Dial the E & M access code that was assigned by the installer, —OR—

if your system has been configured by the installer to use Automatic Route Selection (ARS), dial the ARS access code (9).

4.Wait until you hear a dial tone, then dial the intercom number for the distant party to whom you are transferring the call.

5.If you are doing a screened transfer, stay on the line until the called party answers so that you can announce the call,

—OR—

hang up (unscreened transfer). If the called party does not answer, the call will return to you after the transfer recall timer expires.

NOTE: After transferring the call to the remote end of the E & M tie line, you will have created an unattended conference, and your telephone will appear as though it were on hold.
