There was no cable specifically for connecting the T1® to the L1® Classic. There was a cable with a round connector for connecting the Classic R1 Remote to the L1® Classic.
The cable for connecting the T4S to the L1® Model II, is functionally identical to the cable that was included with the T1®.
Here are some notes about the ToneMatch cable. These notes apply to both the T1® and the T4S.
