Comdial Dxp Correspondance Instructions Manual

							DXP PeripheralsDXP Correspondence Manual
Arranging Voice Mail Ringing Options
(Station Menu, 7.14)
The DXP system automatically enables ringing line preference at the
voice mail station ports. With this feature enabled, the voice mail
system’s automatic attendant will answer calls. You can use direct,
delayed, or night ringing features to determine how quickly or when
voice mail answers the calls. With direct ringing, calls ring at the
voice mail port immediately. With delayed ringing, the calls direct
ring at a telephone before they delay ring the voice mail and the
automated attendant answers them.
Assigning Voice Mail Identification (ID) Number
(Line Menu, 8.18)
You can assign an identification number to each DXP line so that the
voice mail system can provide customized call handling on a per line
basis. Use voice mail system programming to match this ID number to
a particular personal directory or transaction box within the voice mail
system. When the DXP routes a call that is ringing at a particular line
to the voice mail system, it routes the call with the ID number. The
voice mail system then sends the call to the box that corresponds to
the line’s ID number. You can use voice mail system programming to
construct customized answering prompts for the individual boxes,
which allows the voice mail system to answer DXP lines with IDS in a
customized manner.
Enabling Extended DTMF Tones For Voice Mail Use(System Menu, 5.11)
The system provides a means by which you can set the length of the
DTMF tones that it generates when a user dials a number from his or
her telephone. Since the voice mail system may require a different
DTh4F tone length than that which you have provided for the
telephones, the system provides a means for you to set a separate
DTMF tone length for voice mail station ports. The DXP defaults the
length to 80 msec, but you can program other lengths as needed.

							DXP Correspondence ManualDXP PeripheralsSetting The Voice Mail Integration Digits
You can choose the DTMF digits that the DXP sends to a voice mail
system. A voice mail system uses these DTMF digits to determine
system and station status so that it can properly process a call. You
must be versed in your voice mail’s requirements before you can
assign DTMF integration digits in the DXP. The system defaults the
voice mail parameters to match the Comdial voice mail system.
Certain applications in countries with dialing plans different than the
United States may require different integration digits. The default
digits are shown in the following list and discussed below:
Follow Extension ID = 2Intercom/Answer Confirmation = 1
Busy = 2Do Not Disturb = 3
Incoming Intercom Answer = 9Disconnect = A
Follow Extension ID 
- When the voice mail system receives a
forwarded call from a ring no-answer (RNA) or busy station, the DXP
sends to the voice mail system the extension number of the forwarded
call followed by this DTMF digit (n). The DXP sends this digit within
500 ms. of the time the voice mail system answers the call. For
example, if extension 101 is forwarded to voice mail, and voice mail
answers a forward 
RNA or busy forwarded call, the DXP sends 101nto the voice mail system within 500 ms of the answer time.
Intercom/Answer Confirmation 
- The DXP sends this DTMF digit
to the voice mail system to confirm that an intercom path (without dial
tone) is available for the voice mail system’s call transfer or dialing
use. The DXP sends this digit within 500 ms of the time it detects the
voice mail system’s off-hook or hookflash condition. The DXP also
immediately sends this digit to the voice mail system when a station
answers a voice mail transferred call. This action can alert the voice
mail system to disconnect and leave the parties connected.
Busy 
- If the voice mail system transfers a call to a station that is busy
on a call, the DXP sends this DTMF digit to the voice system. When
the voice mail system receives this digit, it can abandon the transfer,
reconnect to the call, and offer the caller whatever options the the
voice mail system has available in its programming. If the 
DXP’sauto-attendant-transfer-on-busy feature is active, the DXP will not
send the DTMF digit to the voice mail system, therefore allowing the
system to transfer a second call to the station.

							DXP PeripheralsDXP Correspondence ManuaPDND 
- If the voice mail system transfers a call to a station that is in
the do not disturb (DND) mode, the DXP sends this DTMF digit to the
voice system. Receiving this digit allows the voice mail system to
distinguish between a busy and a DND condition and offer the caller
the appropriate choices.
Incoming Intercom Answer
- The DXP sends this DTMF digit to the
voice mail system when a station user makes an intercom call to the
voice mail system. This action allows the voice mail system to
distinguish between internal and external calls and offer the caller
appropriate prompts and dialing options.
Disconnect 
- When an outside line or intercom party hangs up, the
DXP sends this DTMF digit to the voice mail system to command an
immediate disconnect. For outside calls, the central office (CO) must
provide disconnect supervision to the DXP, and you must program the
DXP line for abandon hold release and disconnect supervision (see
section 8.11, Abandon Hold Release, for details). At default, the DXP
sends the DTMF tone for the A character as the disconnect digit. Since
a caller cannot dial an A from a telephone. This feature eliminates
callers from causing an accidental disconnect by dialing this digit on
their telephone’s dial pad.

Modem SetupThe system supports the operation of the DXMDM serial data modem.
The DXMDM is a general-purpose, Hayes*-compatible, 300, 1200,
and 2400 automatic baud detect, serial data modem that receives its
operating power and configuration programming from the DXP
system. After you install and connect the DXMDM, you must
program the modem port number into the system memory. Since the
serial data port default for both the modem and the SMDR serial data
printer is main port 2, it is a good practice to choose a different
modem port if the site employs both devices.
Regardless of which port you choose for modem connection, the
system arranges for that port to automatically match the baud rate and
serial data parameters of the modem.
