Configuring SPID parameters for the NI switch type
NI service provider switches use service profile identifications (SPIDs) to identify services (audio, data, or
speech) subscribed to by ISDN devices.
The service provider assigns one SPID for each B-channel. The device cannot place or receive calls until
it sends a valid SPID when it initializes a connection to the service provider switch.
Configuring SPID assignment
SPIDs can be assigned through static manual configuration or dynamic negotiation. You must configure
the SPID assignment as required by the service provider.
• If dynamic SPID negotiation is used, the service provider switch sends available SPIDs to the device.
The device selects the SPID that best suits the current configuration.
• If static SPID assignment is used, you must manually configure the SPIDs assigned by the service
provider on the BRI interface. When establishing a call, ISDN sends the manually assigned SPID in
the ISDN Layer 3 initialization procedure without prior SPID negotiation.
By default, the device uses dynamic negotiation to obtain SPIDs.
Configuring dynamic SPID negotiation
You cannot perform this task when SPID negotiation is present on the ISDN BRI interface.
To configure dynamic SPID negotiation on a BRI interface:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Enter ISDN BRI
interface view.
interface bri interface-number N/A
3. Specify a service
subscribed to by the
device.
isdn spid service [ audio | data |
speech ]
By default, the device chooses the SPID that
includes both speech and data services.
You can repeat the command to specify
multiple services. To specify all the services,
execute the command without specifying
any services.
4. (Optional.) Initiate a
SPID negotiation.
isdn spid auto-trigger
By default, a BRI interface initiates a SPID
negotiation when it receives a call request.
Configuring static SPID assignment
If static SPID assignment is used, you must configure a SPID for each B-channel.
When you perform this task on a BRI interface, follow these guidelines:
• Make sure the configured SPID is the same as the SPID assigned by the service provider.
• Configure a local dialing number (LDN) depending on the service provider requirement. If an LDN
is configured, the setting for the isdn calling command becomes invalid.
• You cannot configure SPIDs in one of the following conditions:
{ A call is present.
{ A SPID negotiation is present.
