  • E1 High Speed Link (HSL) - 2.048 mbps, 12-bit sequence numbers

  • T1 High Speed Link (HSL) - 1.536 mbps , 12-bit sequence numbers

The TDM card supports either E1 or T1 mode at a time. The mode must be defined during driver configuration. It also supports, either HSL or LSL configuration at a time, and it needs to be defined during configuration.
