Comtech EF Data MIDAS Version 4.X NMS Configuration - Manual (Page 38)

MIDAS 4.X NMS Configuration, Rev.6
2–10 Setup and Operation
The display consists of the following major functional areas:
• Space Segment Graph – shows the entire bandwidth of the transponder.
♦ Each block on the graph represents one channel or allocation unit.
♦ Row and column headers label the position of the graph display within
the transponder range.
♦ Labels indicate either channel numbers or IF values, depending on the
selection of the Show Frequency option.
♦ Bandwidth can be allocated from either public or private pools. The
public pool will be allocated on a “First Come, First Served” basis,
but the private pools will be dedicated, guaranteed bandwidth for
customers who require it.
♦ Each block in the graph is color-coded to represent allocated
bandwidth, free bandwidth, control channels, or active calls.
♦ In ‘Display by Circuit Type’ mode, the graph is color-coded to
represent the Data, and Video circuits.
Allocated bandwidth belongs to a pool. By default, bandwidth belongs to the
public pool, but private pools can be created using the Add Bandwidth
window, in which the user can specify the pool type and parameters.
Bandwidth Pool
Setup
The Space Segment’s bandwidth allocation method is based on the use of
Bandwidth Pools. Pools are segments of bandwidth that are designated as one
of the following:
Private Pools This pool type is used for customers that require full-time dedicated bandwidth.
Private pools are a means of having guaranteed available bandwidth at any
time. The private pool’s bandwidth is exclusively allocated to a single customer,
and will not be shared or reallocated, even though it may be unused at certain
times. In addition to the private pool, customers can choose to have an Overflow
percentage added to their account, which allows a certain amount of excess
bandwidth to be borrowed (when available) from the Free pool, if their bandwidth
needs exceed their private pool size
Public Pools This pool type is for general use, and is allocated to customers on a simple “First
Come, First Served” basis. Customers that do not need full-time dedicated
bandwidth may use public pools.
Free Pool This is the unused, or unallocated, portion of available bandwidth on the
transponder. The size of the free pool is constantly changing as bandwidth is
allocated from and returned to the Free pool.
