R0106-HP MSR Router Series Layer 2 - WAN Command Reference(V7)

149
An NI-enabled BRI interface sends SPID information in the Q.931 INFORMATION message 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 an 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.
You cannot execute this command when a SPID negotiation is present on the interface.
Examples
# Set the maximum number of INFORMATION message retransmissions to 5 on BRI 2/4/0.
<Sysname> system-view
[Sysname] interface bri 2/4/0
