Cisco Routers 3/4G connections.
Afternoon, This is a reach out for anyone else using Cisco881g / Cisco887vag routers with 3G backup. We have just started getting the new routers into stock that use the new cellular modems. Our normal connection scripts don't work any more and we have been unable to find the required connection details for either vodafone or telecom connections. I am hoping in exchange for BEER, someone out there has worked it out. (We have a pending case with TAC but I hope this will be faster). Currently we are using: ----------------------------------------------------- *chat-script gsm "" "ATDT*99#" TIMEOUT 30 CONNECT!controller Cellular 0!interface Cellular0 ip address negotiated ip nat outside ip virtual-reassembly in ip virtual-reassembly out encapsulation slip dialer in-band dialer string gsm dialer-group 1 async mode interactive!interface Vlan1 ip address 10.0.0.1 255.255.255.0 ip nat inside ip virtual-reassembly!ip nat inside source list 1 interface Cellular0 overloadip route 0.0.0.0 0.0.0.0 Cellular0!access-list 1 permit anydialer-list 1 protocol ip permit!line 3 exec-timeout 0 0 script dialer gsm modem InOut no exec transport preferred none transport output none* ----------------------------------------------------- The issue is that the dial script always times out.

We’ve got quite a few out there, important bits below, remember NAT on inside interface and diaper-list.
One niggle we haven’t solved is the ones we have on Vodafone suffer from the cellular interface going dead after a few days, we’ve had to resort to inserting a cron in the router to kill the Cellular interface daily then bring it back up – I’ve not spent enough time to work out if it’s a Vodafone issue or a Cisco issue, but it doesn’t happen on the ones we have using Telecom SIM’s.

Scott and Kerry,
That modified chat script was one of the ones i have tried. The debug for
that is:
Feb 12 02:52:01.671: Ce0 DDR: re-enable timeout
Feb 12 02:52:01.671: Ce0 DDR: Attempting to dial hspa
Feb 12 02:52:01.671: CHAT3: Attempting async line dialer script
Feb 12 02:52:01.671: CHAT3: Dialing using Modem script: hspa & System
script: none
Feb 12 02:52:01.671: CHAT3: process started
Feb 12 02:52:01.671: CHAT3: Asserting DTR
Feb 12 02:52:01.671: CHAT3: Chat script hspa started
Feb 12 02:52:01.671: CHAT3: Sending string: AT!SCACT=1,1
Feb 12 02:52:01.671: CHAT3: Expecting string: OK.
Feb 12 02:53:01.671: CHAT3: Timeout expecting: OK
Feb 12 02:53:01.671: CHAT3: Chat script hspa finished, status = Connection
timed out; remote host not responding
Feb 12 02:53:01.671: Ce0 DDR: disconnecting call
Feb 12 02:53:16.671: Ce0 DDR: re-enable timeout
This is using a Vodafone SIM.
The other command of relevance is:
cellular 0 gsm profile create 1 direct.vodafone.net.nz
i have also tried
cellular 0 gsm profile create 1 www.vodafone.net.nz
I would think that i have a faulty unit except this is the second unit i
have tried.

I am hoping in exchange for BEER, someone out there has worked it out. (We have a pending case with TAC but I hope this will be faster).

For the HSPA+7 cards, use a different dialler string: chat-script gsm "" "AT!SCACT=1,1" TIMEOUT 60 "OK" Also, you need to carefully check the GSM profile settings on the card, in exec mode: show cellular 0/0/0 gsm ... There's a very useful doc at http://www.computecnetworks.com/?q=node/51 which is a life-saver. Contact me off-list if you need help. Kerry On 12/02/2014 15:37, Laurence Bullivant wrote:

The issue is that the dial script always times out. Hopefully this is all recognizable to someone who has gone though the same pain as we are.
Thanks in advance.
