LC STM-1 electrical interface SMB PDH service E1/T1 electrical interface 2 mm HM connector Framed E1 electrical interface DB78 connector E3/T3 electrical interface LC Ethernet service 10BASE-T, 100BASE-TX RJ-45 100BASE-FX LC 1000BASE-SX/LX LC 1000BASE-FX LC ATM service STM-1 optical interface: 155 Mbit/s MTRJ/LC Audio and data service RS-232 or RS-422 data and audio interface 2 mm HM connector DDN service Physical interface complying with multiple protocols, including V.35, V.24, X.21, RS-449, and EIA-530 2 mm HM connector Framed E1 electrical interface DB78 connector G.SHDSL service Single pair high-bit-rate digital subscriber line interface RJ-11 Clock interface The clock signals at the 120-ohm external clock interface can be 2048 kbit/s or 2048 kHz. RJ-45 Power interface 2x–48 V DC/–60 V DC power interfaces+1x24 V DC interface 4-core socket Environment monitoring interface The EMU board provides the following interfaces: 12 housekeeping signal inputs and 6 housekeeping signal outputs An RS-232/RS-422 serial communication interface 2 mm HM connector The SCB board provides the following interfaces: Four housekeeping signal inputs and 2 housekeeping signal outputs Four transparent data interfaces RJ-45 Management interface A modem interface RJ-45 An NM interface RJ-45 Orderwire interface An orderwire phone interface RJ-11 The OptiX 155/622H provides the following clock sources for synchronization: external clock sources, line clock sources, and tributary clock sources. When working in locked mode, an OptiX 155/622H can select any of the following clock sources as the reference clock: External 2048 kHz or 2048 kbit/s G.703 clock source Clock source from an interface on a line board Clock source from an interface on a tributary board Clock source from a line or tributary interface on an SCB board The OptiX 155/622H has a capacity of 21.25 Gbit/s higher order full cross-connection or 5 Gbit/s lower order full cross-connection. It can be configured as multiple terminal multiplexers (TMs), add/drop multiplexers (ADMs), or multiple add/drop multiplexers (MADMs). It also supports service grooming and protection among these systems. In this way, the networking capability and the service grooming capability among networks are significantly improved. The OptiX 155/622H can construct networks flexibly. It supports point-to-point, chain, ring, hub, and mesh networks. When the OptiX 155/622H functions as the access equipment, it can construct hybrid networks with Huawei Metro and OSN equipment series. The OptiX 155/622H can also construct hybrid networks with third-party equipment.
