1.2.2 Highly Integration
The size of the OptiX OSN 3500 subrack is 730mm (H) × 496mm (W) × 295mm (D),
and it can be installed in 300mm-deep ETSI cabinet. A 2.2m-high and 300mm-deep
ETSI cabinet can house two OptiX OSN 3500 subracks
The OptiX OSN 3500 subrack has fifteen slots for processing board: Slot 1 ~ Slot 8
and Slot 11 ~ Slot 16. Slot 17 can also hold processing board. Besides, the OptiX
OSN 3500 has sixteen slots for interface board, one slot for auxiliary interface board,
and three fan modules. In practice, a variety of board configurations offer incremental
bandwidth increases as needed and support E1, T1, E3, DS3, E4, STM-1 (E/O),
STM-4, STM-16 and STM-64 service, transparent transmission of AU3 service, and
the 10/100/1000M Ethernet service as well.
1.2.3 Ethernet Service
The OptiX OSN 3500 integrates Ethernet access into the same SDH platform that
transports voice traffic. Ethernet over SDH lets service providers augment TDM
services with Ethernet, and allows delivery of data traffic over existing facilities. The
OptiX OSN 3500 can
Support 10M/100M/1000M Ethernet traffic.
Support encapsulate protocols such as High-level Data Link Control (HDLC),
Link Access Procedure-SDH (LAPS) and Generic Framing Procedure (GFP).
Support Layer 2 switching and the ability to classify Ethernet traffic as defined
in IEEE 802.1Q-tag standard.
Support transparent transmission and convergence of Ethernet traffic.
Support Link Capacity Adjustment Scheme (LCAS), achieving capacity
adjustment dynamic of transmission bandwidth and protection of concatenated
group..
Support Layer 2 VPN function and implements the EPL(Ethernet Private Line) ,
EVPL(Ethernet Virtual Private Line), EPLn/EPLAN(Ethernet Private LAN) and
EVPLn/EVPLAN(Ethernet Virtual Private LAN) services.
1.2.4 Interface
Abundant SDH interfaces, PDH interfaces, Ethernet interfaces, clock interfaces,
alarm interfaces and administration interfaces are provided by the OptiX OSN 3500,
as shown in Table 1-1.
