The SBC Core supports the use of the Master Trunkgroup Resource Manager (MTRM) to manage call and bandwidth resources on clients spread across multiple SBCs, thus enabling service providers to support enterprise customers using enterprise-wide CAC management down to the location and trunk group levels.

The Master Trunkgroup Resource Manager (MTRM) is basically a client/server model consisting of a Master Trunk Group Server (MTRG server) and Master Trunk Group Client (MTRG client). The server and client are associated with a common name. MTRG-server and MTRG-client instances can co-exist in the same SBC, or can reside in different SBCs.

The MTRG-server is configured with a CAC pool shared amongst its registered MTRG-clients. This CAC pool consists of call and bandwidth resources.

The MTRG client registers with the respective MTRG server and requests for a configurable margin of call and/or bandwidth resources. The CAC resources configured on the server are shared and dynamically redistributed between the registered clients. Each client can optionally maintain its own set of local resources and/or obtain aggregate resources from the respective server. As idle client resources fall below a configurable margin (calls/bandwidth per request), a client requests more resources from the server. The server, depending on the availability, may or may not grant the resources.

Master Trunk Group (MTRG) Server

When configuring the parent server, the parentMtrg, parentRequestMaxCalls and parentRequestMaxBW parameters are not needed.

Command Parameters

Command parameters

ParameterLength/RangeDescription
bandwidthPerRequest 2480-248000000Use this parameter to define the bandwidth (in kbit/second) to use for each request from the parent Master Trunk Group. (default = 5000)
callsPerRequest 1-16777214This parameter defines the number of calls to use for each request from the parent Master Trunk Group. (default = 10)
maxBandwidth -1 to 2147483647

The maximum bandwidth allocated to this MTRG server. The value "-1" specifies unlimited bandwidth. (default = 64000)

maxCalls -1 to 2147483647The maximum number of calls allocated to this MTRG server. The value "-1" specifies unlimited calls. (default = 1000)
modeN/A

  • inService (default)
  • outOfService 
mtrmConnPortIndex1-128The MTRM connection port index which this MTRG server will use to communicate.
parentMtrg Up to 23 charactersThe name of the parent MTRG server.
parentRequestMaxBw-1 - 2147483647The maximum bandwidth that can be requested from the parent MTRG server. The value "-1" specifies unlimited bandwidth. (default = -1)
parentRequestMaxCalls-1 - 2147483647The maximum number of calls that can be requested from the parent MTRG server. The value "-1" specifies unlimited calls. (default = -1)
stateN/A
