Technical description of IBAS180 (GF2488-01D) equipment
Provide a variety of management interfaces.
IBAS180 equipment provides F interface, f interface, DEBUG interface, MBUS, QF, MON, ALM, CTR interface. The F interface is connected to the workstation, uses the standard Ethernet communication protocol, receives the management information issued by the workstation, and controls every single disk according to its management strategy; the F interface is connected to the PC, when the upper management network has not been established, or when the equipment maintenance needs, it can be used for equipment debugging.
1.3 system functions of IBAS 180 Devic.
The main functions of IBAS180 equipment include cross-connection function, management function, a protection switching function, official telephone function, and system timing function. IBAS180 equipment consists of three parts: the main channel, maintenance management, and system timing. The main channel completes the function of add-drop multiplexing and transmission of service signals. The maintenance and management part provides functions such as management communication interface, official contact, expense processing, and so on. The system timing function provides the tracking function of the network timing (BITS) and provides the holding function when the network timing failure occurs. The timing functions of the system include free oscillation mode, branch timing mode, and line timing mode to adapt to various engineering applications.
1.3.1 Cross Connect Feature.
The high-order cross-connection matrix and low-order cross-connection matrix of IBAS180 equipment make it have the ability to schedule VC-4 and VC-12 services, and can realize the interworking and exchange of interface-side services at the VC-4 and VC-12 levels. IBAS.
The crossover capability of 180 equipment includes low-order crossover capability and high-order crossover capability. The low price crossover capacity is 1008 × 1008VCmur12, and the high order crossover capacity is 70 × 70VC-4.
For services entering the interface side of a cross-network, IBAS180 can provide a variety of cross-connection methods:
The service on the line side enters the cross matrix from one side and outputs in the same time slot on the other side.
2. Add and drop.
The service from the line goes down to the branch according to the configured time slot, and the service from the branch is inserted into the line according to the configured time slot. ADM network elements provide access to services in this way. IBAS.
The time slots up and down the 180 pairs of branches are arbitrary, and any available time slots can be allocated on the line.
IBAS180 can realize that the service on the line can be down to multiple branch time slots at the same time, or the service on the branch can be inserted into multiple line time slots at the same time.
Loopback includes line loopback and branch loopback. The service from the line enters the cross matrix from one side, and the output from the same time slot on the same side is called the line loop; similarly, the service from the branch is called the branch loop through the cross matrix from the same time slot of the branch.
The cross-connection between lines is applied to protection switching, service grooming, and path selection, which can enhance the networking ability and the viability of the network.
It has great crossover ability and rich branch interfaces, and the rates of STM-1, STM-4, and STM-16 are fully compatible.
The high-order crossover capacity is 70x70VC4, and the low-order crossover capacity is 2016 × 2016VC-12.
A single system supports 3 STM-16 light directions, up to 8 622m or 14 155m, up to 160m 2m and 20 FE.
Perfect multi-service processing, provide FE interface, support transparent / layer 2 switching, virtual cascade, LCAS, VLAN, QinQ, and other functions, support ATM/IMA business processing function.
Can be used as an MSAP device to provide PDH optical branch disk direct access to the MSAP edge optical terminal.
The business interface board is compatible with IBAS110A.
Suitable for network aggregation/access layer, especially for high-capacity station access
