1548Terminal Translation Initialization

Data modules

Data modules have different tones and digit sequences.

In the merge and separate control flow, different tones are given to the telepho ne

user to give the current status of the TTI operation. Ins tead of audible tones, status

messages are displayed on a telephone connected to a data module when

activating the TTI sequence through keyboard dialing. If the TTI State field is set

to data, you see the data display messages. If the TTI State field is set to voice,

you hear the tones.

For a stand alone data module, the TTI merge/separate digit sequenc e is enter ed in

one line at a dial prompt:

■DIAL: <TTI feature access code><TTI security code><ext>

Separate prompts are not given for the TTI security code and extension.

Voice/data telephones

A telephone with a data terminal (DTDM) is treated as a telephone in the TTI

merge and separation sequence. The DTDM is merged with and separ ated from i ts

hardware translation at the same time the telephone is merged or separated. The

TTI merge and separate sequence can only be initiated through the telephone for

DTDMs; it cannot be initiated through the data port.

ISDN BRI telephones

The TTI separation sequence for Automatic-TEI SPID-initializing BRI tel ephones

is identical to the sequence used for telephon es. However, the merge sequence is

different.

■Separation sequence

1. Feature Access Code

2. Security Code

3. Extension

■Merge sequence

1. Connect the telephone to any port to get power.

2. Program the SPID to the extension with which it will be merged.

3. Unplug the telephone (this is necessary even if the telephone is

connected to its intended port).
