EM6T/EM6F － Functions and Features

The EM6T/EM6F is an FE/GE interface board, which provides four FE electrical

interfaces and two GE interfaces. The EM6T has similar functions to the EM6F. The only

difference is as follows: the GE interfaces on the EM6T always function as electrical

interfaces whereas the GE interfaces on the EM6F use the SFP modules and therefore

can function as two optical or electrical interfaces. The GE electrical interfaces on the

EM6F and the EM6T are compatible with the FE electrical interfaces. The EM6T/EM6F accesses, processes, and aggregates four FE signals and two GE

signals. In R2 version, the backplane service bus is 1G. EM6T/EM6F support LAG function, support ERPS. EM6T/EM6F support E-Line and E-Lan. EM6T/EM6F supports synchronous Ethernet. EM6T/EM6F support ETH-OAM function.

GE electrical interfaces on the front panel of the EM6T are compatible with the FE interfaces. The GE

interfaces on the front panel of the EM6F use pluggable SFP optical modules. The FE electrical interfaces and GE electrical interfaces support the MDI and MDI-X adaptation modes. The FE interfaces support 10M full duplex, 10M half duplex, 100M full duplex, 100M half duplex, and

auto-negotiation. The GE electrical interfaces support 10M full duplex, 10M half duplex, 100M full duplex, 100M half

duplex, 1000M full duplex, and auto-negotiation. The GE optical interfaces support 1000M full-duplex and auto-negotiation.

AUX － Functions and Features

The AUX is the auxiliary and management interface board of the OptiX RTN 950 V1R2.

One NE can house only one AUX. The AUX provides multiple auxiliary interfaces and management interfaces, including the

one orderwire interface, one synchronous data interface, one asynchronous data

interface, and one four-input/two-output external alarm interface. Provides one orderwire interface. Provides one 64 kbit/s synchronous transparent data interface. Supports one 19.2 kbit/s asynchronous transparent data interface.Supports the input of four channels of external alarms. Supports the output of two channels of external alarms. Supports hot swapping. Supports the detection of the board power supply.

The OptiX RTN equipment also supports the orderwire group call function. For example, when an OptiX RTN equipment calls the number of 888, the orderwire group call number, all the OptiX RTN equipment orderwire phones in the orderwire subnet ring until a phone is answered. Then, a point-to-point orderwire phone call is established.
