undo isdn spid service
View
ISDN BRI interface view
Parameter
audio: Supports audio service.
data: Supports data service.
speech: Supports voice service.
Description
Using the isdn spid service command, you can configure the service types that must be supported in SPI negotiation on the BRI interface using NI protocol. Using the undo isdn spid service command, you can delete the service types that must be supported in SPI negotiation on the BRI interface using NI protocol.
There are three types of services. You can select any one or none. None means all services are supported. By default, SPID supports data and voice service simultaneously.
For BRI interfaces using National ISDN protocol, you need to negotiate or initialize a SPID before originating a call. During negotiation, SPCS may send multiple SPIDs, and carry the service types supported by the SPID, so the router needs to choose a proper SPID according to the local service type.
This command can only be applied on the BRI interface using NI protocol.
Example
Set the service type supported by the BRI interface to data and voice.
