3 vSTP TDM Support Feature Overview

The ADAX HDC3 PCIe card supports direct access using PCIe Pass Through. This means that a single ADAX 4-port or 8-Port HDC3 PCIe card can only be accessed from only one VM at a time.

The M3RL layer in vSTP MP VM communicates with the MTP2 layer running on the ADAX HDC3 card via the MTP2 Adapter layer.

The MTP2 Adapter layer uses the libraries and APIs provided by ADAX to communicate with ADAX HDC3 Card.

The TDM link implementation supports the following modes:

• E1 Low Speed Link (LSL) – 64 kbps and 56 kbps
• T1 Low Speed Link (LSL) – 64 kbps and 56 kbps
• E1 High Speed Link (HSL) – 2.048 mbps, 12-bit sequence numbers
• T1 High Speed Link (HSL) – 1.536 mbps , 12-bit sequence numbers

ADAX HDC3 card supports either E1 or T1 mode at a time, and needs to be defined during Driver configuration.
