Configuring The Tspid Timer And Information Retransmission; Enabling Nit Mode For Ni-Type Switches Incapable Of Spid Negotiation - HP MSR Router Series Wan Access Configuration Manual

To configure SPIDs on a BRI interface:
Step
1. Enter system view.
2. Enter ISDN BRI interface
view.
3. Assign a SPID to the B1
channel.
4. Assign a SPID to the B2
channel.
Configuring the TSPID timer and INFORMATION
retransmission
An NI-enabled BRI interface sends SPID information in Q.931 INFORMATION messages during SPID
negotiation and Layer 3 initialization.
The TSPID timer sets the maximum interval that ISDN waits for a response after it sends an
INFORMATION message. The timer starts when the device initiates a SPID negotiation or Layer 3
initialization.
The interface retransmits the INFORMATION message if it has not received a response from the service
provider switch before the TSPID timer expires. This process continues until the interface receives a
response or the maximum number of INFORMATION retransmissions is reached.
To configure the TSPID timer and the maximum number of INFORMATION retransmissions:
Step
1. Enter system view.
2. Enter ISDN BRI
interface view.
3. Set the TSPID timer.
4. Set the maximum
number of
INFORMATION
retransmissions.
NOTE:
You cannot perform this task when a SPID negotiation is present on the interface.
Enabling NIT mode for NI-type switches incapable of SPID
negotiation
Typically, the NI-enabled BRI interface must pass SPID negotiation or initiation before it can place a call.
