TTI separation from a telephone
To complete a TTI separation, complete the following steps from the telephone that needs to be
separated:
1
Dial the TTI separate FAC.
2
Dial the TTI security code.
— If the code is correct, you receive dial tone.
— If the code is not correct, you receive intercept tone.
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 may want to review the following system restrictions:
•
The
TTI Ports
field on the System Capacity screen 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.
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.
— If the
TTI State
field is set to voice, then default TTI translations are generated for every
unadministered port on all digital, hybrid, and analog boards.
