The SCB integrates the functions of the SCC unit, XC unit, STG unit, EOW unit, OI2D/OI4D/O16D, and SP2D.
Table 1 provides the functions and features of the SCB.
Table 1 Functions and features of the SCB
Function and Feature
SCB
Cross-connect capability
The higher order cross-connect capacity is 21.25 GB and the lower order cross-connect capacity is 5 GB.
Supports the cross-connection at the VC-4, VC-3, and VC-12 levels, and realizes the service grooming between lines, tributaries, and the line and the tributary.
Line functions
Provides two STM-1/STM-4/STM-16 optical interfaces. The optical interface supports the hot-pluggable SFP optical module.
The STM-1 optical interface is named OI2D, the STM-4 optical interface is named OI4D and the STM-16 optical interface is named OI16D.
The STM-1 optical interface can be equipped with the optical module of the S-1.1, L-1.1, or L-1.2 type. The STM-1 optical interface uses the SC/LC connector.
The STM-4 optical interface can be equipped with the optical module of the S-4.1, L-4.1, or L-4.2 type. The STM-4 optical interface uses the SC/LC connector.
The STM-16 optical interface can be equipped with the optical module of the S-16.1 type. The STM-16 optical interface uses the LC connector.
Provides two synchronous timing sources for the clock unit.
Supports the high-precision time synchronization function to realize the synchronization of time over the entire network.
Processes section overheads and higher order path overheads.
Supports the setting of K-byte reporting, K-byte transmitting, and K-byte passing-through.
Provides the transparent DCC and orderwire byte channel.
Supports the setting and querying of the J0/J1/C2 byte.
Processes the AU pointer.
Supports maintenance features such as inloop and outloop on VC-4 paths, setting of the overhead byte to be sent/received, pass-through test of the K bytes, and checking of K bytes.
Supports the MSP and ALS function.
Tributary functions
Accesses 16xE1 signals.
Maps E1 signals into VC-12s asynchronously.
Provides 75-ohm unbalanced interfaces and 120-ohm balanced interfaces. The characteristics of the interfaces meet the requirements specified in ITU-T G.703.
Processes VC-12 path overheads, configures all service paths, monitors alarms and performance events on the service paths, and communicates with the SCC unit.
Provides inloop and outloop to test the quality of E1 services or to locate a fault, thus facilitating the maintenance of the equipment.
Provides synchronous timing sources for the clock unit.
Clock functions
Supports the Non-SSM protocol, standard SSM protocol and extended SSM protocol.
Provides the synchronous clock signal for the boards in the system.
Supports the following working modes: trace mode, holdover mode, and free-run mode.
Supports the control of the priority of clock sources.
Controls the clock source switching function.
Supports the processing and setting of the S1 byte.
Provides two 2048 kHz or 2048 kbit/s external clock interfaces whose impedance is 120 ohms.
Time function
Provides two high-precision time output interfaces. The time synchronization function complies with IEEE 1588 V2.
The external time interface supports the output of the 1pps (also called the second pulse) and the high-precision time information.
The 1pps interface uses the RS-422 level and the external time serial port uses the RS-232 level.
The 1pps interface and the external clock interface use the same interface. Hence, when the 1pps function is enabled, the external clock function is invalid.
The external time serial port and the COM3/COM4 transparent data interface use the same interface. Hence, when the external time function is enabled, the transparent data interface function is invalid.
System control functions
Exchanges information with other boards, realizes the data configuration function, and collects performance data and alarm data.
Provides a standard Ethernet interface and RS-232 data terminal equipment (DTE) interfaces so that the NMS can manage the equipment.
Orderwire functions
Provides an orderwire interface and supports conference calls and the broadcast function.
Provides four RJ-45 RS-232 serial data interfaces and supports point-to-multipoint connection of equipment to transparently transmit user data.
Provides 4-input/2-output housekeeping interfaces. The housekeeping input interface is used to monitor the status of the external equipment and the housekeeping output interface is used to output alarm indications and control the external equipment.
Other functions
Detects and reports performance events and alarms.
Provides 18 embedded control channels (ECCs).
The external clock interface can transparently transmit DCC bytes that are used to exchange management information when the OptiX 155/622H forms a network with the third-party equipment.
Generates alarms when the fans are faulty, and manages the fans.
