Redundant Link connection options

We have a redundant link we can use (all be it slow) if our primary link fails.
Over the last few days (suspecting a dodgy port on the DSLAM and un co-operative Telco staff) we may need to get in via the redundant link to resolve things.

I was thinking of using pfSense in some way to do it and then have it register to DynDNS upon connection (can't get a static I.P constantly and don't want the link always-on). We have an offsite monitoring system which warns us of the link going down.
At least this way I can log in remotely and reset the router if need be rather than drive to the site after hours.
The redundant connection is PPPoE based over a IP-Wireless Modem.

Any ideas would be helpful.

Yes, you can use pfSense to configure the two WAN links in failover mode.
Refer to http://doc.pfsense.org/index.php/Multi_WAN_/_Load_Balancing#Setting_up_load_balancing_and_failover for details.
Configure pfSense to use DynDNS allows you to access the system remotely via dynamic IP by using it's name.
