Troubleshooting Routers

A-24

The router pings the remote side of the dial-on-demand link to provide data to

transmit across the link, and displays a “data received” message when it receives a

response.

# 21: mm/dd/yy 13:09:16.174 INFO SLOT 2 SWSERV Code: 23

Data received for dial on demand circuit 2.

# 22: mm/dd/yy 13:09:16.178 DEBUG SLOT 2 SWSERV Code: 46

Connector COM1: FSM State: V25BIS_WAIT_DATA_OR_IND(2)

Connector COM1: FSM Event: V25BIS_EVENT_DATA_AVAIL(7); isdn flags: 0x9

# 23: mm/dd/yy 13:09:16.178 TRACE SLOT 2 MODEMIF Code: 34

Connector COM1: DATA Available.

# 24: mm/dd/yy 13:09:16.178 DEBUG SLOT 2 SWSERV Code: 44

SW Sent you are cc 2 message to line 1

The line is given a valid circuit number (2) in order to be activated

# 25: mm/dd/yy 13:09:16.193 INFO SLOT 2 SWSERV Code: 7

Dial on demand circuit being established on line 1.

The router forwards a call request number (CRN) to the V.25bis modem. It uses

the phone number conﬁgured in the “Outgoing” ﬁeld of the circuit deﬁnition.

# 26: mm/dd/yy 13:09:16.225 TRACE SLOT 2 MODEMIF Code: 35

Connector COM1: Sent CRN cmd to T3053

In this example, the cable connection to the modem is loose. The router fails to

receive a response from the modem indicating that it received the CRN. The

router exceeds its inactivity timeout threshold, and drops DTR to terminate the

connection to the modem.

# 27: mm/dd/yy 13:10:17.446 DEBUG SLOT 2 SWSERV Code: 46

Connector COM1: FSM State: V25BIS_WAIT_FOR_ADAP_RSP(3)

Connector COM1: FSM Event: V25BIS_EVENT_TO(0); isdn flags: 0x4009

isdn_fsm_TO_WAIT - calling drop_dtr

# 28: mm/dd/yy 13:10:18.518 TRACE SLOT 2 MODEMIF Code: 27

Connector COM1: Connection timeout, retry in progress

# 29: mm/dd/yy 13:10:18.518 DEBUG SLOT 2 SWSERV Code: 46

Before g_delay for retry timer in - isdn_fsm_CONN_DELAY_IND

The router reinitializes the link with the modem after detecting CTS is high.

# 30: mm/dd/yy 13:10:18.784 TRACE SLOT 2 MODEMIF Code: 53

Connector COM1: CTS has come up.

# 31: mm/dd/yy 13:10:18.784 DEBUG SLOT 2 MODEMIF Code: 9

Connector COM1: modem present V.25bis mode

Once again, the router sends the CRN to the modem.
