Managing Telephones
3. Dial the extension of the telephone to be separated.
- If you have dialed the extension of the telephone currently merged with this telephone,
you receive confirmation tone.
- If you have dialed the extension of the telephone currently merged with this telephone,
but the extension is being administered, you receive reorder tone. Try the separation
again later.
- If you have not dialed the extension of the telephone currently merged with this
telephone, you receive intercept tone.
- If the system is busy and cannot complete the separation, you receive reorder tone. Try
the separation again later.
Fixing problems
If you are having difficulty using TTI, you might want to review the following system restrictions:
The TTI Ports field on the System Capacity screen (type display capacity) shows
●
the number of TTI ports used in a server running Communication Manager. This field
shows only the number of TTI ports being administered. If a TTI exceeds the maximum
number of ports, the port is not administered and cannot be added. In that case, a
telephone cannot be added. For details on the System Capacity screen, see Maintenance
Commands for Avaya Communication Manager, Media Gateways and Servers,
03-300431.
BRI endpoints are only counted as one TTI port. For example, for every two BRI endpoints,
one TTI port is counted. As such, you can have two telephones assigned to one port. If
either endpoint is administered, the TTI port count is reduced by 1.
The total number of translated telephones and Voice TTI ports in a system is limited to the
●
maximum number of administered telephones supported in the system. The total number
of translated data terminals and Data TTI ports in a system is limited to the maximum
number of administered data modules allowed in the system.
Set the TTI State field to voice and then set the TTI State field to data. When you use this
●
order, voice and then data, you reduce the chance of a user trying to use TTI on a
data-only terminal that does not have TTI port translation. This can happen when the
number of telephones allowed by the system is twice the number of data terminals. For
example, if the system limit for telephones is 15,000 and 7,500 for data, then when TTI
was turned on for data first, only the first 7,500 unadministered ports would get TTI port
translations.
When TTI is activated for the system, the following actions take place:
●
- If the TTI State field was previously activated but in a different state (such as, a voice to
data state), the old TTI translations are removed and the new ones added on a board by
board basis.
