Music on Hold (Internal or External Source) 
 
Implementing features, see also Manager E Music on Hold

Definition  
An integrated music source (hardware module) makes it possible to play music for waiting parties during switching operations.
As an alternative, you can use the following optional modules with HiPath 3550, HiPath 3350, HiPath 3500 and HiPath 3300:
 •   EXMNA (connection option for an external music source) (for U.S. only)
 •   EXM (connection option for an external music source) (not for U.S)
 •   EXMR (connection option for an external music source)
 •   MPPI (with music component) (not for U.S)
All HiPath 3000 models allow you to define up to six (16 for V6.0 or later) MoH sources on analog interfaces for the six possible ITR groups. Devices other than Genius or Mozart must be connected to a 600 Ohm transformer.

No Music On Hold  
If you choose this option, Music on Hold is completely inactive. If an external caller is blind transferred you will hear ring back with this option.
The EXMNA card limits the level at which MOH can be heard over outside lines and is therefore FCC compliant without external limiters.
Callers hear MOH if in Consultation Hold state, Park state, and in a transfer state if configured. Also, queued callers in an UCD environment can hear MOH if so configured.
MOH can be configured in one of three ways:
 1.   No Music on Hold: The held party hears nothing (silence).
 2.   MOH with ring tone: The held party will first hear MOH during the Consultation process. When a call is transferred to the destination, the MOH is replaced by ringback tone.
 3.   MOH without Ring Tone: The held party will hear MOH until the called party answers the call.

HiPath Xpressions Compact-based MOH for HiPath 33xx, 35xx and 38xx  
As of HiPath 3000 Version 4.0 SMR 7, HiPath Xpressions Compact supports Music On Hold (MOH).
With HiPath 3000/5000 V6.0 and later there are 16 ITR groups (in Version 5.0 there were only 6). However, only a further 6 MOH sources can be assigned to the 16 ITR groups from the integrated voicemail. The MOH ports are no longer available for voicemail operation and should be removed from the voicemail port hunt group.
Each MOH channel features an MOH mailbox. Callers in the queue hear mailbox greetings as MOH. Each MOH mailbox has four greetings which can be individually customized. These are integrated in the MOH and are always played as an endless loop.
Each MOH mailbox has a default announcement. You can record individual MOH by simply changing the MOH mailbox greetings via HiPath 3000 Manager E/C. The music or announcements to be played should be available in PCM WAV format, 8kHz, 16 bit, mono.
The MOH function of an available HiPath Xpressions Compact board can be remotely configured.

Additional loop resistance for analog interfaces  
There are external MOH boards for analog interfaces which have no integrated loop resistor. If such an MOH board is connected to an analog subscriber line module, the party on hold does not hear any music on hold. This can be the case:
 •   after reconnecting an external MOH board
 •   after a restart of the HiPath 3000
Therefore, it is necessary to insert an additional loop resistor and two capacitors between the analog interface of the analog subscriber line module and the MOH board. The block diagram looks as follows:

Dependencies/Restrictions  

 Subject  
 Dependency/Restriction  
EXMNA  
EXMNA is used only in the U.S.  
EXM, EXMR, EXMNA, MPPI  
Connecting the EXM, EXMR, EXMNA or MPPI board automatically switches the system over to the external music source.  
MOH  
HiPath 3250 provides limited internal MOH.  
MOH source  
You cannot use the logical port "0" as an MOH source.  
MOH source at analog ports  
If the MOH source is turned on (loop active) you need to disconnect and then reconnect it (interrupting the loop) after configuring the analog port.  
MOH for IP workpoint clients  
For this feature, MOH channels (= number of MOH data streams for IP workpoint clients) of the HG 1500 boards will be provided. For load limitation, the maximum number of possible MOH data streams per HG 1500 board is limited to 10 (i.e., max. 10 IP workpoint clients can simultaneously listen to MOH).  
If the station on hold is an IP workpoint client of an IP trunk, the internal MOH is used. External MOH is not intended for IP.  
Number of phones for which "Music on Hold" can be played simultaneously  
There is no restriction on the number of phones for which "Music on Hold" can be played simultaneously1. However, if the "Music on Hold" is provided over an IVM port, the number of devices is limited to 32.  
1Provided via a/b interface (add-on devices, external connection, external MOH), internal MOH or MOH module (e.g., MPPI, EXM,)
