ISDN BRI telephones
The TTI separation sequence for Automatic-TEI SPID-initializing BRI telephones
is identical to the sequence used for telephones. 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 service profile identifier (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).
4. Connect the telephone to its intended port (this port should indicate
Equipment Type: TTI Port).
5. Receive dial tone.
— If there is dial tone, the merge is complete.
— If there is no dial tone, the telephone’s SPID is not an
available extension.
You can dial the TTI merge sequence for BRI sets only if a user separates a BRI
extension from its set and then wants to undo the process by reassociating the set
to the same extension. Note that you cannot use the SAT to put an X in the port
field of a BRI set that is still connected to the switch. You must use the TTI
separation sequence from the set.
Analog Queue Warning Ports and External Alert
Ports
The analog queue warning port (used for hunt groups) and the external alert port
may be administered with an X in the Port field. These extensions can be merged
to an analog port via TTI. The merge must be done by an analog set, and then the
analog set is unplugged from the port. These extensions cannot be separated from
their port location with the TTI feature. A TTI separate request from one of these
ports gives you intercept treatment.
