Providing 1008 × 1008 VC12 level or 48 × 48 VC3 level or 16 × 16 VC4 level non-blocking cross connection, supporting unidirectional, bi-directional and broadcasting.

    Providing sub-network connection protection, channel protection and 1+1 multiplex section protection.

    Applicable for a number of network configurations: point to point, linear, ring, star, tree, multi-ring, ring crossing, etc.

    Provides E1, T1, E3, T3, 10Base-T and 10/100 Base-T traffic interfaces.

    Provides four extended slots reserving traffics to be extended.
