Networking Modes

Point to point network

The packet rates of point-to-point networking include STM-1, STM-4, STM-16, and STM-64. Dual TM configuration devices can form 1 + 1 protection or no protection, single TM configuration device without protection.

• When configured as a 1 + 1 protection mode, the two LPUs provide mutual protection to improve the reliability of service delivery. The disadvantage is that the service access capability is reduced. When configured as unprotected, service access can be improved, but the reliability of service delivery is reduced. Point to point network for the large-capacity inter-office relay, expansion between the Bureaus.

Chain network

The packet rate of ZXMP S385 in chain networking includes STM-1, STM-4, STM-16, and STM-64. The chain network consists of TM devices and ADM devices. ZXMP S385 formed a chain network.

For four-fiber chain

It can be configured as channel protection and multiplex section protection. Dual TM devices and ADM devices can form a 1+1 protection chain, single TM devices and ADM devices can form an unprotected chain network.

• When configured as a 1+1 protection mode, the two LPUs provide protection for each other to improve the reliability of service delivery. The disadvantage is that service access can be degraded.

• When configured as unprotected mode, the service access capability can be improved. The disadvantage is that the service delivery reliability is reduced.

The chain network is suitable for long-distance trunk network, the traffic volume chain communication network, as well as the chain side chain network.

Ring network

The loop interface of the ring network has a self-sealing feature. The branch services between network elements can be transmitted end-to-end through two directions (eastward and westward). This network topology has strong survivability and self-healing capability. In the high-capacity fiber-optic network. The self-healing ring structure can be divided into two categories, namely, channel switching ring and multiplexing section switching ring. From the perspective of the abstract functional structure, the channel switching ring and the multiplexing segment switching ring belong to sub-network connection protection and path protection respectively. The ring network usually formed by ZXMP S385 includes a two-fiber / four-fiber bidirectional MSP ring and two-fiber unidirectional channel switching ring of STM-4 / STM-16 / STM-64.

Double node interconnection network (DNI)

ZXMP S385 constitute a DNI (Dual Node Interconnection, two-node interconnect)

Two-node interconnection (DNI) networking is actually the intersection of two ring networks, which can provide inter-ring service protection. The two rings can be configured with the same type of protection. For example, the channel ring intersects the channel ring and can also be configured for different protection types. For example, the channel ring intersects the ring of the multiplex section. The rate of ZXMP S385 DNI networking is determined by the ring rate, which is commonly used at the STM-16, STM-64 rate levels. DNI network provides a variety of path protection and important node protection, usually applied to the local network transmission trunk network.

Mixed network

ZXMP S385 can implement hybrid networking with other SDH-based multi-service node devices (such as ZXONE 5800, ZXMP S330, ZXMP S325, ZXMP S200, and ZXMP S150) of ZTE, and a hybrid networking diagram of ZXMP S385 and ZXMP S330 devices.

The hybrid networking can implement services and public service interworking. The two ring networks can be configured with the same protection mode. For example, the channel ring intersects with the channel ring and can also be configured with different protection types, such as the intersection of the channel ring and the multiplex ring. On the networks where SDH NEs such as ZXONE 5800, ZXMP S330, ZXMP S325, ZXMP S200, and ZXMP S150 coexist with WDM NEs such as ZXWM M900, ZXMP M800, and ZXMP M600, set the monitoring network port Qx The Qx port of the port and the WDM network element are interconnected through the crossover network cable to realize the remote monitoring of the WDM network element.
