Description
PF4E8 overview
Huawei OSN1800V 4*port 2M optical+8*port E1/T1 electrical interface board PF4E8.
The PF4E8 board provides four 2 Mbit/s optical ports and eight E1/T1 electrical ports.
The board can be used on the WDM equipment to support the upstream/downstream processing of PDH signals, and the access and processing of eight E1/T1 signals. In addition, the board can transparently transmit 2 Mbit/s optical signals to the peer equipment over a long distance, and process and transmit C37.94 optical signals.
The PF4E8 board processes four 2 Mbit/s optical signals and eight E1/T1 electrical signals and overheads, manages alarms and performance events, and provides maintenance features.

Basic functions |
The PF4E8 board can access four 2 Mbit/s optical signals and eight E1/T1 electrical signals. |
NMS port |
|
Service processing |
Receives and processes four channels of 2M optical signals and eight channels of E1/T1 electrical signals. When the 2M optical port works in 2M optical transparent transmission mode, the transparent transmission of IEEE C37.94 is supported. When the 2M optical port works in C37.94 deframing mode, the deframing and framing of IEEE C37.94 are supported. This satisfies the transmission requirements of relay protection devices in the electric power industry. |
Optical port specification |
Supports I-2M optical ports and is compatible with the C37.94 standard. NOTE: I-2M is an optical port specification defined by Huawei. |
Optical module specifications |
|
Tributary clock sources |
|
Overhead processing |
Processes path overheads (such as J2 and V5 bytes) at the VC-12 level. |
Alarm and performance event |
Provides various alarms and performance events, facilitating equipment management and maintenance. |
Maintenance |
Provides the following maintenance features:
|
Hitless protection switching |
Supported. Upstream mode: VC-12, E1 |
VC-12 SNCP |
Supported. |
E1 SNCP |
When the 2M optical port works in C37.94 deframing mode, the port can function as the E1 SNCP sink port. When the 2M optical port works in 2M optical transparent transmission mode, the port cannot function as the E1 SNCP sink port. |
TPS protection |
Not supported. |
2M ASON |
When working with TNZ5UXCMS, the board supports this function. |
