Mapper/Framer for STM-4/STS-12
and STM-1/STS-3
The MetroMapper 622 is a mapper/framer capa-
ble of mapping datacom traffic into SONET/SDH
transport payloads. On the line side, the
MetroMapper 622 supports protected
STS-12/STM-4 and STS-3/STM-1 interfaces. On
the client side, up to sixteen Ethernet interfaces
(10/100 Mbps), two 1 GE and one OIF SPI-3 inter-
face with up to 64 logical channels are provided.
The Ethernet traffic or the packets coming from
the SPI-3 interface are 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 64 virtual concatenated channels
is supported. MetroMapper 622 provides Ether-
net IEEE802.1q VLAN operations and enables
Ethernet over MPLS.
