Pad Level-Transmit, Receive
(Gain And Attenuation Settings For Line Transmit And Receive)
Description:This feature enhances the Tl-El digital carrier transmission option, the pad level programming
feature adjusts voice levels for both the transmit and receive circuits in the individual channels.
The choices include: Gain 2, Gain 1, Nominal, Loss 1, Loss 2, Loss 3, Loss 4, and Loss 5.
These settings provide an approximate +6 to -15 dB range of choices. Starting at the Nominal
setting, each gain level represents an approximate 3 dB amplification of the signal level from
the previous setting, and each loss level represents an approximate 3 
dB attenuation of the
signal level from the previous setting. Because digital transmission does not lose volume level
as readily as analog transmission does, it is likely that the receive level may be noticeably
higher when using the 
Tl option. Therefore, you may need to select a low setting such as Loss 2
for the voice level receive parameter when programming this feature for Tl lines that are being
used exclusively for voice transmission. Further, if you choose a setting to increase the receive
gain, you should carefully examine speakerphone operation. It is possible to select a receive
gain that will, under certain conditions, interfere with proper speakerphone operation.

8.1.18DISA And DISA Voice Options
You can assign an identification number to each 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 
Plus routes a call that is ringing at a particular line to the voice mail system to
be answered, it routes it 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. This allows the IDed DXP
Plus lines to be answered in a customized manner by the voice mail system’s automatic
attendant. Refer to 
Section 14.5 for complete voice mail programming details.

8.4Dire& Inward Dialing (DID) Support
The DID line board allows incoming CO calls to reach internal DXP Ph intercom extensions by direct dialing.
No attendant assistance is necessary. Since DID lines are incoming only, their direct appearance is limited to
attendant stations where status indication may be useful. DID operation requires a group of published directory
numbers (400 maximum) provided by the telephone company central office (CO). These directory numbers are
incoming only and the DXP Plus translates them to the appropriate personal or group intercom number for
ringing. The lines will accept outgoing DTMF digits during a call to support personal identification number
dialing and similar uses.
The DXP 
Plus handles DID calls in the same manner that it handles regular intercom calls and will forward them
via a hunt list or a call forwarding scheme. An unanswered DID call will either continue to ring or route to a
progmmrned ring no-answer (RNA) destination.If neither forwarding nor RNA is available, the system provides
no routing.
The system returns a 
ringback signal to DID callers when a called station is in the do not disturb (DND) mode.
The system returns an off-hook indication to the CO when a DID line is disabled. The 
DXP Plus synchronized
ringing feature does not have any affect on DID calls, and the Caller ID feature is not available.
The DID line is a reverse-battery, loop-start, two-wire voice circuit.(The term reverse battery means that it is the
DXP 
Plus and not the CO that provides tip and ring supervisory battery for the loop.)The DXP Plus sends and
receives all supervisory and voice signals across the voice pair and provides all necessary signal control at its line
interface.
In the idle state, the loop is open at the CO end, with the 
DXP Plus maintaining on-hook battery polarity on the
circuit.
The CO requests service from the DXP Plus by applying a resistance across te line causing a current flow
to occur. The DXP 
Plus recognizes the current flow as a CO connection and prepares for the incoming call. The
CO does not send ringin since the DXP Plus generates it internally and sends it to the stations.
After the DXP 
Plus receives all of the address digits, it translates them based on the appropriate DID block
translation table and attempts to place the call to the desired station. To assure that the caller will always hear
ringback prior to the call being answered (for example, when answered by voice mail), the system delays the
station ringing until it applies 
ringback tone.
The called station sounds a distinctive ringing based on the ring code in the translation table.If the translation
table has a name for the CO digit sequence that the DID call is on, the LCD of the called station displays that
name. Otherwise, the station displays the DID block name followed by a portion of the CO digit string. If there is
neither CO digit string name nor DID block name programmed, the station displays the CO digit string alone.
If an incoming call is for either an unassigned or an uninstalled station, the DXP 
Plus routes the call to the DID
block alternate extension.If the DID Block alternate extension is unavailable, the DXP 
Phs routes the call to the
Dial 0 attendant.If the Dial 0 attendant is unavailable, the DXP 
Plus returns reorder tone to the caller.
The DXP 
Plus returns call progress signals to the CO in the interval after it receives address signalling and before
it answers. It does this within 1.5 seconds after completion of address signalling.
When a called station answers a DID call, the DXP 
Plus sends answer supervision to the CO by applying reverse
polarity to the line. The DXP 
Plus maintains this polarity reversal until either the station goes on-hook or the CO
opens the loop.
The CO signals a line disconnect condition to the DXP Plus by opening the loop. When the DXP Plus detects the
CO disconnect, it returns the line to idle polarity and changes the line from busy to idle. The DXP Plus signals a
line disconnect condition to the CO by returning the supervision battery polarity to the on-hook state. While
immediate start lines return to idle at once, wink and dela start lines maintain busy status until the DXP 
Plus
detects CO release.
