ITS821 Call Park Keys
ITS821 IP Telephone Set has 4 Call Park keys in total.
When the ITS821 is in conversation state, the active call may be parked on a free park
key. Park keys are distinguished with their back-lighting states. If a park key is not
lighted (OFF state), its is free. If a park key is lighted (ON state), it has a parked call.
When a free park key is pressed, the active call parks on it and the ITS821 becomes
free for the next call. When a lighted park key is pressed again then the parked call on
this key is retrieved.
ITS821 Hands-free and Mute Keys
Spkr key starts the handsfree function. When Spkr key is pressed, it lights ON. Mute
key starts the mute function. When Mute key is pressed, it lights ON. During the mute
state, the ITS821 stops transmitting voice towards the other party in conversation.
ITS821 Shift and Function Keys
Shift key together with F1, F2, F3 keys provide several flexible functions in usage.
When the Shift key is OFF (not lighted), Rdial key is used for re-dialing,
Disc key is used for disconnecting the call, and Conf key is used for creating
a conference.
If the Shift key is pressed once or more than once, shift state changes. Shift
states are indicated and distinguished with the backligthing state of the key.
Shift key may be fast blinking, slow blinking, or continuously lighted. In
each of these shift states, a different function can be programmed for F1, F2,
F3 function keys. In other words, when the Shift key is OFF, F1 key is for re-
dialing. When the Shift is fast blinking, F1 key may be for another function.
When the Shift is slowly blinking, F1 key may be for some other function.
When the Shift is continuously lighted, F1 key may be for a completely
different function.
ITS821 Shift and Quick-access Keys
ITS821 IP Telephone Set has 30 quick-access keys in total. These keys are numbered
00 to 29. Each key is with the back-lighting technology. Whenever a key is pressed, a
pre-programmed number on this key is dialed. If pre-programmed numbers of these
keys are the local users of the Telesis PBX or switching system then quick-access keys
also operate as the BDP (busy display panel). That means, keys show busy, free,
ringing states of local users with their lights ON, OFF, blinking respectively.
If the Shift key is pressed once or more than once, shift state changes. Shift states are
indicated and distinguished by the backligthing state of the key. Shift key may be fast
blinking, slow blinking, or continuously lighted. In each of these shift states, a
different number can be programmed onto a quick-access key. In other words, when
the Shift key is OFF, “quick-access key 00” may be programmed for the number
“aaa…..”. When the Shift key is fast blinking, “quick-access key 00” may be
programmed for the number “bbb…..”. When the Shift key is slowly blinking, “quick-
access key 00” may be programmed for the number “ccc…..”. And when the Shift key
is continuously lighted, “quick-access key 00” may be programmed for the number
“ccc…..”.
ITS821 Alphabetic Keyboard
Quick-access keys on the ITS821 IP Telephone Set may
also be used as Alphabetic or text keys. Whenever it is
necessary ITS821 IP Telephone Set automatically
interprets pressed quick-access keys as letters or characters
right next to the numbers. This alphabetic or text keyboard
is especially useful in operating some functions within the
ITS821. One example is searching names through the
Directory list.

again retrives the held call.
Trans key is to transfer a held call to another destination.

pressing Rec key starts recording and the key is lighted (ON). When the
key is pressed again, recording stops and the key lights OFF. During the
same conversation record function can be used several times for multiple
and partial recordings.
