Step

Setting the ISDN functionality of an ISDN interface

An ISDN interface can provide the ISDN user-side or network-side functionality. For two ISDN
devices to communicate with each other, you must configure one end as the network side and
configure the other end as the user side.
When you perform this task, follow these guidelines:
•
Typically, an ISDN interface is operating as the user side. However, when a BRI interface on a
BSV card is connected directly to an ISDN phone, you must configure the BRI interface as the
network side.
•
You must configure the ISDN interface as the user side in the following situations:
The BRI interface for data services must operate on the user side.

ANSI, AT&T, ETSI, NI, or NTT is configured.

•
You cannot perform this task when a call is present on the ISDN interface.
To set the ISDN functionality of an ISDN interface:
Step
1. Enter system view.
2. Enter ISDN BRI or PRI
interface view.
3. Configure the interface
as the user side or
network side.
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.
