553-3001-306 Standard 10.00 January 2002
An outgoing connection from a digital telephone is considered established
after the end of dialing time is elapsed. Alternatively, an outgoing call can be
established after the end of dialing time is elapsed, or can be established
immediately by pressing an octothorpe (#) after the last digit is dialed.
Attendant End-to-End Signaling
The attendant can send DTMF tones to either the source or destination party
using the AEES key on the Attendant Console. If there are two receiving
parties on the current active loop key, the attendant can press the EXCL SRC
or EXCL DEST key to exclude one of the connected parties before pressing
the AEES key (defined in LD 12). Only one party on the active loop key
(source or destination) can receive the DTMF signal. After pressing the
AEES key, the attendant can press digits to send DTMF tones out to the
source or destination party. To terminate the EES operation, the attendant
should press the AEES key again. The states for the EXCL SRC, EXCL
DEST, SRC loop, and DEST loop keys remain the same as before the EES
key is pressed.
Operating parameters
The EES capability extends to internal analog (500/2500 type) telephone calls
and incoming trunk calls.
A call must be established before using the EES feature. An outgoing call is
considered established 14 seconds (DP trunk) or four seconds (2500-type
telephone or Digitone trunk) after the last digit has been outpulsed. The length
of this delay can be changed through service change. EES can be performed
after end of dial time out, or when an answer supervision has been received
from the far end, by pressing the octothorpe key (#) after the last digit.
EES is allowed only on CO, FEX, WATS, TIE, CCSA, DID, and CAMA
trunk types.
EES is not available on analog (500/2500 type) telephones.
EES eliminates the use of the conference loop.
The AEES key, like other flexible programmable keys, cannot be configured
on key 0 or key 1 of the Attendant Console.
