Has anyone encountered any compatibility issues between the TDK Global Freedom 5660-V.90 PCMCIA modem and HARC/HDSP-equipped chassis? We have a customer who has frequent (but not always) problems with connecting to any of our POPs that have TC gear, but never experiences a problem when calling a POP that has a Cisco AS5300 or AS5400. Haven't been able to find a modem compatibility list on 3KB (anybody know a URL for one?) so am not sure if this is a known issue or not. 3kb search turned up nothing. Any solutions welcome.
