The MetroMapper 2.5G is a multi-service framer capable of mapping
datacom traffic into SONET/SDH transport payloads. On the line side, the
MetroMapper 2.5G supports protected STS-48/STM-16 and STS-12/
STM-4 interfaces. On the client side, one OIF SPI-3 with up to 128 logical
channels are provided. Data from the SPI-3 interface is encapsulated by
either the GFP-F, LAPS (X.85/.86) or PPP mapping scheme. Low-order and
high-order virtual concatenation (VCAT) with Link Capacity Adjustment
Schemes (LCAS) for up to 128 virtual concatenated channels is supported.
MetroMapper 2.5G provides Ethernet VLAN ID processing and enables
MPLS label update processing.
