The MTP2 layer in the SS7 protocol stack defines the functions and procedures of the signaling system for a reliable transfer of signaling messages over an SS7 signaling link. The MTP2 layer is a service provider to the MTP3 link layer, and at the same time it is a service user of the underlying trunk layer.

A conceptual illustration of the MTP2 layer is provided to the right.

TelcoBridges and MTP2

TelcoBridges supports MTP2 as part of its SS7 signaling stack. It also provides the following functionality:

  • 56, 64, n x 64 kbps low-speed links (LSL)
  • 1.5 and 2 Mbps high-speed links (HSL)
  • Supports dynamic link configuration

Supported MTP2 variants

  • ITU-T, Q.701, Q.703
  • ANSI T1.111.3
  • JT Q.703 (TTC, Japan)
  • NTT Q.703 (NTT, Japan)
