T1 Interfaces and Cabling

Hi, I purchased a T1 card for a Cisco 4331 router but it turns out that it doesn't fit my available T1 hand off. My router has a NIM-2T card with Smart Serial style of connectors but my T1 handoff is RJ48 style witch fits the NIM-2MFT-T1 card.

I've done some searching around but can't seem to find any available places to pick up a RJ48->Smart Serial cable. There are lots of other cables available like V.35->Smart Serial or TIA-449->Smart Serial, but I haven't found a way to go from RJ48->Smart Serial.

Is there any solution to this predicament other than to purchase a NIM-2MFT-T1 card?

Thanks much!
