GENERAL DESCRIPTION
VSC9125 (HOVCAT48e) is a 2.488 Gbps, multiservice, SONET/SDH data mapping device that supports both contiguously concatenated as well as virtually concatenated transport channels. A maximum of 48 data channels can be mapped into transport channels. Fully integrated Link Capacity Adjustment Scheme (LCAS) protocol is implemented. For route-diverse applications, external memory can accommodate differential delays up to 128 ms between tributaries.
   
VSC9128 (HOVCAT192e) is a 10 Gbps, multiservice, SONET/SDH data mapping device that supports both contiguously concatenated as well as virtually concatenated transport channels. A maximum of 64 data channels can be mapped into transport channels. The Link Capacity Adjustment Scheme (LCAS) protocol is supported. For route-diverse applications, external memory can accommodate differential delays up to 128 ms between tributaries.
