Configuring Spid Parameters For The Ni Switch Type; Configuring Spid Assignment - HP MSR Router Series Wan Access Configuration Manual

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:
Step
1. Enter system view.
2. Enter ISDN BRI
interface view.
3. Specify a service
subscribed to by the
device.
4. (Optional.) Initiate a
SPID negotiation.
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.
Command
system-view
interface bri interface-number
isdn spid service [ audio | data |
speech ]
isdn spid auto-trigger
114
Remarks
N/A
N/A
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.
By default, a BRI interface initiates a SPID
negotiation when it receives a call request.
