4 Using the TELES.iTA/2TR Box

4.1 External Calls

Unlike when using other private branch exchanges, you will hear the dial tone for an outside

line as soon as you pick up the receiver. You do not have to dial for outside access. If both B

channels are busy, or if the connection between the TELES.iTA/2TR Box and the ISDN line

is interrupted, you will hear two short tones and a long pause. This indicates that for the time

being you can only make internal calls.

4.2 Internal Calls

It is possible to call the other internal extension of a TELES.iTA/2TR Box from either exten-

sion. The extension number corresponds to the port number (either 1 or 2). Enter 

by the desired port number:

Example: You are calling from a device attached to port 1 and would like to call the tele-

phone on port 2. You simply enter:

4.3 Disconnect

Some telephones are equipped with a so-called disconnect key. TELES.iTA/2TR Box emu-

lates this function when a two key command sequence is used. Just enter:

4.4 Sending Commands to the PBX

This function is only necessary, if your TELES.iTA/2TR Box is attached (subordinate) to a

PBX. Lift the receiver and press the # key. The commands entered then go straight to your

PBX; nothing is valid for the TELES.iTA/2TR Box.
