Voice Mail System The MSC supports Voice mail capabilities. If an incoming call cannot be completed
the Voice Mail may be provisioned to allow the caller to leave a brief voice
announcement for the called party. Voice Mail allows otherwise interminable calls to
be routed to a Voice Mail system.
Voice Mail is a system option. Motorola can act a coordinator to help implement this
type of system or, the provider can add this type of system independently.
Operations and Maintenance Center
The Operations and Maintenance Center (OMC) is the network element management
subsystem that establishes, maintains, collects information about the network, and
presents it to the system operator. This data is used primarily to support the daily
operation of the network radio system elements and to provide the system operator
with valid information for future planning decisions. As the complexity and control
requirements of the iDEN system and its relationship to other systems increases, the
need for control and monitoring equipment also increases. The OMC exists in at
least one form in every system.
• OMC - Radio (OMC-R) — required for radio system management
• OMC - System (OMC-S) — for possible Switching system management
• OMC - Network (OMC-N) — a possible Network Operation Center (NOC)
Others may be implemented as the need arises. Only the OMC-R is discussed.
Physical Components
The OMC-R (Figure 2-14) may exist in different platforms:
• S1000
• OMC 3000
• OMC 3500
S1000 The OMC S1000 is a legacy system used in older and smaller service areas.
Advances in technology and aging of the S1000 indicate this system my not have the
performance and handling capacity for continued use. The S1000 can support up to
300 EBTS sites and may be networked with other OMCs running a minimum of
Software Release 8.0. The S1000 must be a secondary processor in this network
configuration. The S1000 is no longer supported with SR 9.1.
