Nortel Networks NN10033-111 manual Interworking with third-party gateways, Supported media, QoS

Nortel Networks Confidential Overview 9

If the platform sending the INFO receives a response code other than the ones listed above, it treats the response as a valid audit response, and does not bring the call down.

The CS 2000 sends a 200 OK for an empty INFO message and a 481 response code if the call leg does not exist.

Supported media

The following are the media supported by the interworking of MCP and the CS 2000:

•G. 711 PCMU

•G. 711 PCMA

•G. 729

•G. 723

•G3 Fax

•Modem

Note 1: This list represents a full list of the media capabilities the MCP can use while interworking with the CS 2000. The actual list of supported media types depends on the capabilities of the gateways that the CS 2000 is using.

Note 2: G3 Fax and Modem media calls are used only for CS 2000 gateway calls as there are no MCP endpoints that support either of these two media types.

QoS

MCP implements its Quality of Service through the DiffServ (Differentiated Service) feature. The parameters of MCP QoS include the following:

•QoS DiffServ code for signaling: specifies signaling quality for SIP clients.

•QoS DiffServ code for audio: specifies audio quality for SIP clients.

•QoS DiffServ code for video: specifies video quality for SIP clients.

•QoS 802.1p for service priority: specifies service priority for SIP clients.

Interworking with third-party gateways

The MCP can use SIP signaling between the MCP network and a third-party SIP-enabled gateway. The third-party gateway provides the necessary signalling interworking between the MCP network and the other network to which the gateway is connected. For example, a
