I installed a new T1 card (HWIC-1CE1T1-PRI)to Cisco 2821 (having CME running on it). The router didn't recognize the card.
They first told me that i need to have DSP module (PVDP) installed. After i confirmed that it's installed they said i need a recent IOS version to recognize the card. The IOS version in this router is 12.4(9)T7.
Does this version work?
