Alarms and
Performance
The DAP collects and maintains performance metrics, usage and call record
information. Alarms and status information is collected and reported every half-
hour. Performance metrics and usage is also collected for optimization and billing.
Dispatch
Provisioning
The DAP maintains databases that are used to control the activity of a mobile MS on
the system.
• Dispatch Home Location Register (D-HLR) — for conditional dispatch call
users
• iDEN Home Location Register (iHLR) — for conditional packet data users
• Dispatch Visited Location Register (D-VLR) — for mobility and activity of
all dispatch and packet data users
These are discussed in On-Air Programming and Dispatch Call Processing.
Packet Duplicator
Physical Components
Each Advanced Packet Duplicator contains:
•MTX Boards
• High Speed Serial Interface
MTX Boards The processing and control logic for the operation of the APD is on the MTX single
board processor. The OMC-R exchanges status and control information with the
MTX through a RJ45 twisted pair connector on the board. The MTX board also
contains 4 slots that use the 32-bit Peripheral Component Interface (PCI) bus
standard for the connection of 4 serial interface boards
High Speed Serial
Interface
The High Speed Serial Interface (HSSI) contain ports that are opened and closed
under the control of the MTX board. When a port is opened the incoming packet is
duplicated to the output ports to the EBTS sites as determined by the mobility
management of the DAP.
