MetroMapper™ 2.5G
Multi-Service Framer for STS-48/
STM-16, STS-12/STM-4
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.
