1.1.3  MADM

MADM, composed of ADMs, provides the function of ADM and cross-connects the ADMs within it. The ADMs may be at one rate or different rates. MADM is the core of a complex network. Figure 1-7 shows its functional block diagram. The OptiX OSN 3500 can be configured as the multiple ADMs at any rate ranging from STM-1 to STM-64 to form an MADM.

Figure 1-7 Functional block diagram of MADM in the OptiX OSN 3500

MADM is used at the central node of a ring with chain network, intersecting rings, tangent rings, or HUB network.

2.  Hybrid Networking Capability

The OptiX OSN 3500 can work at the access layer or convergence layer, or interwork with the multi-service transmission platform (MSTP) equipment developed by Huawei Technologies Co., Ltd (hereinafter referred to as Huawei). For example, it can interwork with the OptiX OSN 9500, the OptiX 10G, the OptiX OSN 2500, the OptiX OSN 1500, and the OptiX Metro 1000 to provide a complete metropolitan area network (MAN) solution. Figure 1-10 shows a hybrid network composed of the OptiX OSN 3500 and other equipment.

Figure 1-10 Hybrid network of the OptiX OSN 3500 and other equipment

The OptiX OSN 3500 can interwork with other equipment at the same layer. At the convergence layer, the OptiX OSN 3500 can work with the OptiX OSN 2500, the OptiX Metro 3000, and the OptiX Metro 3100. At the backbone layer, the OptiX OSN 3500 can work with the OptiX 10G, as shown in Figure 1-11.

1.2.2  Grooming Capability

The OptiX OSN 3500 has a powerful capability of grooming services of different rates at the access layer or convergence layer, as shown in Figure 1-12. It provides up to 80 Gbit/s higher order cross-connect and 20 Gbit/s lower order cross-connect capability.

For the Ethernet service, the equipment can realize functions such as point-to-point transparent transmission, point to multi-point convergence, Layer 2 switching, Layer 2 virtual private network (VPN), and multiprotocol label switching (MPLS).

For the ATM service, the equipment can realize bandwidth sharing and statistical multiplexing on the ring network. It supports VP-Ring and VC-Ring.
