Reconnection 819 Router after connection failure

casper999
Level 1
Level 1

Hi all,

I have a Cisco 819 WAN Router (C819 Secure M2M GW (non-US) 3.7G HSPA+ R7 w/SMS/GPS).

Software: Cisco IOS Software, C800 Software (C800-UNIVERSALK9-M), Version 15.2(2)T, RELEASE SOFTWARE (fc1)

For dialing in at my Provider (T-mobile Germany), I use the following chat-script:

chat-script gsm "" ATZ "" AT+CGDCONT=1 "OK" "AT!SCACT=1,1" TIMEOUT 60 "OK" "ATD*99#" "CONNECT"

Dial-In is successful after Reboot.

Now, i want to simulate a conenction fault, e.g. termination by mobile provider.

So I used the command "clear int cellular 0".

After that, The router can't dial in again.

Debug shows:

Dec  7 11:04:03: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access1, changed state to down

Dec  7 11:04:14: CHAT3: Attempting async line dialer script

Dec  7 11:04:14: CHAT3: Dialing using Modem script: gsm & System script: none

Dec  7 11:04:14: CHAT3: process started

Dec  7 11:04:14: CHAT3: Asserting DTR

Dec  7 11:04:14: CHAT3: Chat script gsm started

Dec  7 11:04:14: CHAT3: Sending string: ATZ

Dec  7 11:04:14: CHAT3: Sending string: AT+CGDCONT=1

Dec  7 11:04:14: CHAT3: Expecting string: OK

Dec  7 11:04:19: CHAT3: Timeout expecting: OK

Dec  7 11:04:19: CHAT3: Chat script gsm finished, status = Connection timed out; remote host not responding

Is the "clear interface cellular 0" the wrong way to test this, or why can't the Router reconnect?

The only solution is a reboot, but that is not the best option. The router should automatically redial.

Any ideas?

Thanks in advance!
