The BRIM-T6 default ring speed setting is 16 Mbps. The other available

standalone device, remove the chassis cover from the device to provide
access to the BRIM-T6’s component board surface.
2. Slide the jumper down over pins 2 and 3 to select a 16 Mbps setting or
over pins 1 and 2 to select a 4 Mbps setting.
3. Reset the device containing the BRIM-T6.
