Measures reported by CUCMGWStatTest

Cisco offers a wide variety of voice and video gateways. A gateway provides interfaces that allow the Unified Communications network to communicate with an external network. In the data environment, a gateway might translate between a Frame Relay network and an Ethernet network, for example. In a VoIP environment, voice gateways are the interface between a VoIP network and the public switched telephone network (PSTN), a private branch exchange (PBX), or analog devices such as fax machines. In its simplest form, a voice gateway has an IP interface and a legacy telephone interface, and it handles the many tasks involved in translating between transmission formats and protocols. Gateways enable Cisco Unified Communications Manager to communicate with non-IP telecommunications devices and with Internet Service Providers over SIP. In addition, when gateways are properly configured, many can take over for a Cisco Unified Communications Manager when it is unreachable.

Most Cisco gateways offer multiple deployment options and can be deployed using any one of a number of protocols. Depending on the gateway that you want to deploy, your gateway may be configurable using any of the following communication protocols:

  • Media Gateway Control Protocol (MGCP)

  • Skinny Call Control Policy (SCCP)

  • Session Initiation Protocol(SIP)

  • H.323

If the gateways are not configured correctly on the call manager, it can cause gateway registration failures. Then, the gateway will no longer be able to communicate with the Call manager which can inturn lead to serious service bottlenecks. Any gateway connectivity issues can also affect the D-channel service, which can be a cause for concern as the D-channel is responsible for carrying control and signaling information. Due to this, user experience will suffer. To avoid such poor user experience, it is essential to keep a vigil on the registration status of the gateways and the active status of the D-channel. CUCMGWStatTest helps administrators in this regard. This test monitors the gateways and reports the registration status of the gateway. This test also reports whether/not the D-channel is active. This will proactively help administrators identify issues with the gateway and rectify the same before it adversely affects the user experience.

Outputs of the test : One set of results for each gateway being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
status Indicates the current status of this gateway.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Values Numeric Values
Unknown 1
Registered 2
Unregistered 3
Rejected 4
Partially registered 5

Note:

This test typically reports the Measure Values listed in the table above to indicate status of the gateway. However, the graph of this measure is represented using the numeric equivalents only.
dcStatus Indicates the current status of the D-channel in this gateway.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Values Numeric Values
Not applicable 0
Unknown 1
Active 2
Inactive 3

Note:

This test typically reports the Measure Values listed in the table above to indicate status of the D-channel in the gateway. However, the graph of this measure is represented using the numeric equivalents only.
