PRODUCT BRIEF
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
MetroMapper™Ethernet over MPLS.
622
Applications
I Access / edge aggregation
I MSPP
I ADM
I Mapper mode: packets are
mapped between Ethernet and
SDH/SONET interfaces
I Packet mode: packets from the
SPI-3 interface are forwarded to
SDH/SONET and Ethernet inter-
faces, and vice versa
Features
Framer
I Multi-Rate SONET/SDH framer
with STS/AU and VT/TU pointer
processing capabilities
I Processes a single
STS-12/STM-4 or a quad
STS-3/STM-1
I Supports 1+1 line protection
I Payload Pointer interpretation and
generation
I Fully SONET/SDH compliant
I Provides full performance moni-
toring for high- and low-order
paths
I Provides high-order and low-order
virtual concatenation according to
ITU-T G.707
I Supports up to 64 virtual concate-
nated groups (VCG)
I Flexible concatenation of up to
12 high-order paths and up to
64 low-order paths into any virtual
concatenation group
I Supports up to 336 VT1.5 or
252 TU12 low-order paths
I Provides following mapping
schemes:
- AU-4 / VC-4 / TUG-3
- AU-3 / VC-3 or STS-1 / STS-SPE
I External buffer for up to 48 ms
differential delay compensation
I Different VCG group types are
defined:
- N × VC-12, N × VC-11,
N × VT1.5 SPE, N × VT2 SPE
(N ≤ 64)
- N × VC-3, N × STS1 SPE
(N ≤ 12)
- N × VC-4, N × STS3c SPE
(N ≤ 4)
I Provides flexible mapping of any
VCG into any VC-4/STS-3
I Fully integrated support for the
Link Capacity Adjustment Scheme
(LCAS) protocol according to
ITU-T G. 7042
I Provides hitless increase and
decrease of multiple members
VCG
SPI-3 Interface
I 64 logical channels each of them
running in 32-bit mode
I Packet mode with variable block
length
