MOH port
The MOH (messages-, or music-, on-hold) connector on the upper right side of the cabinet is a standard

from an external source such as a radio or CD player.
Maintenance/SMDR serial port
The Maintenance/SMDR port is a standard DB9 serial connector located on the side of the cabinet.
Use a standard shielded serial cable, DB9-to-DB9, for printer-to-computer (this is usually male-to-female).
Note: The maximum distance from the cabinet is 100 ft.
The output from the Maintenance/SMDR port is, 8 data bits, 1 stop bit, and no parity. The pinout is:
Range: Programmable for 300, 1,200, 2,400, 4,800, 9,600, 19,200, or 38,400 bps.
Default: 38.4K.
SMDR
The IVX C-Class system continuously outputs real-time SMDR call records to the port.
Note: The system will buffer up to 1000 SMDR records (80 KB) in non-volatile memory (CompactFlash) when
the maintenance port is in use for programming or uploading. When the buffer reaches capacity, the
oldest records are discarded.
External paging device connection
A dry contact overhead-paging device can be connected to the system through the port card's 66 block.
The overhead paging port is fixed (located on the main board) as extension 199 for programming
purposes and user access.
Audio connection
The audio pair is connected to the 66 block at terminal 33 and 34. The pair's impedance is 600 ohms.
Dry contact control
The manner in which the dry contact pair is punched down on the 66 block sets the pair as normally
open (sending a page to the port will close the contacts) or normally closed (sending a page to the port
will open the contacts).
Connect the dry contact pair of the device to IVX as follows:
• Terminals 35 and 36 to provide normally open operation
or
• Terminals 35 and 37 to provide normally closed operation.
The port can be used with zone paging units.
Note: The port doesn't support talk-back paging (which requires a CO port), nor does it support CO ring
through the port.
