Introduction
Cisco Media Gateway Controller Software Overview
The Cisco Media Gateway Controller (MGC) Software Release 7 is part of solutions that enable the routing of time division multiplexing (TDM) traffic to or through an IP network. These solutions include:
•
Cisco SS7 Interconnect for Access Servers Solution—Provides a gateway that allows dial-in users to dial in through a TDM network to access traditional data services on an IP network. This solution supports SS7 signaling through use of Cisco Signaling Link Terminals (SLTs).
•Cisco SS7 Interconnect for Voice Gateways Solution—Enables voice calls between the traditional TDM network and telephony services on an IP network. This solution also hosts voice calls between two TDM networks, but it uses two types of call routing: gatekeeper call routing and MGC call routing.
In both of these solutions, the Cisco MGC software is combined with one or two Sun hosts, Cisco SLTs, and network interface cards in the Sun hosts. This combination of hardware and software is known as the Cisco SC2200 product.
Terminology
The following terms are used in this document:
•Cisco SC host—A Sun host server running Cisco MGC software.
•Cisco SC node—The combination of the Cisco SC2200 product and the control signaling network. The SC node consists of all solution components except the media gateway.
•Simplex SC node—A node that uses a single SC host. Typically, this type of node is used for solution evaluation tests or for small installations. In a simplex configuration, any loss of service in the Cisco SC host disrupts all call traffic.
•Continuous-service SC node—A node that uses two SC hosts to prevent system down time caused by failure of a single SC host. Calls in progress are maintained when one SC host fails. Continuous-service nodes use SLTs to preprocess SS7 signaling and distribute signaling to both SC hosts. If a failover occurs, all stable calls are maintained.
Provisioning Tools
Three provisioning tools are distributed with the Cisco MGC software:
•Cisco Media Gateway Controller Manager (CMM), distributed with software Release 7.3(x) and 7.4(x)
•Release 1.6 of the Cisco Voice Services Provisioning Tool (VSPT), used with software Release 7.4(x)
•Man-Machine Language (MML), distributed with software Release 7.3(x) and 7.4(x)
Tip Notes are used in this chapter to identify the procedures and other elements that differ in the CMM (used with Cisco MGC software Release 7.3[x] and 7.4[x]) and the VSPT (used with software Release 7.4[x]). However, most procedures are the same for both tools. See Table 1-1.
The CMM/VSPT can be used alone or in conjunction with MML commands to provision your system. Table 1-1 shows the differences between provisioning methods.

System basics
|
X Window System GUI1 front end, SNMP back end.
Note Any client software supporting X, such as Reflection for remote management, can be used.

CLI2 that interacts directly with the SC host.
|
System hardware/software requirements
|
Sun Sparc station running Solaris 2.6.
Note Running the CMM/VSPT on the same host as the
Cisco MGC can adversely impact performance. We recommend using a separate server.
|
Runs on the SC host.
|
Batch file support
|
CMM:No VSPT: Yes.
|
Yes.
|
Level of network/telephony experience required
|
Little experience required; very easy to use.
|
Requires a high level of experience with MML and the Cisco MGC software.
|
Best used for
|
•Setting up a single configuration or few configurations on individual machines.
•Modifying an existing configuration.
|
•Creating batch files to provision many Cisco SC nodes or retrieve measurements.
•Modifying configurations (experienced users).

•Using the CMM/VSPT and MML tools
•Provisioning solution components
•Creating worksheets to use during provisioning
CMM/VSPT Overview
The CMM/VSPT is an X Window System GUI that accesses Cisco SC node information by using SNMP. You use the CMM/VSPT to perform the following tasks:
•Setting up your initial system configuration
•Adding or deleting system components (for example, point codes, gateways, switches, and other nodes)
•Setting up links and signaling services between components
•Provisioning component properties
•Setting up number analysis and routing
•Saving or changing subsequent provisioning sessions
See Cisco Media Gateway Controller Software Release 7 Provisioning Guide and the Cisco Media Gateway Controller Software Release 7 Dial Plan Guide for more information.
MML Overview
MML is a CLI that is used to directly interface with the Cisco SC host through a terminal. You can access MML through a console attached to the Cisco SC host, or through a Telnet session to the Cisco SC host.
See Cisco Media Gateway Controller Software Release 7 Provisioning Guide and the Cisco Media Gateway Controller Software Release 7 Dial Plan Guide for more information on provisioning with MML. Refer to the Cisco Media Gateway Controller Software Release 7 MML Command Reference Guide for more information on MML commands.
