TNW1PF4E8,Huawei OSN 1800 12 Port Electrical Interface Board

Huawei OSN 1800 12 Port Electrical Interface Board TNW1PF4E8 Overview

TNW1PF4E8: 4-port 2M optical + 8-port E1/T1 electrical interface board

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 consists of an interface unit, a CODEC unit, a mapping/demapping unit, a logic control unit, and a power supply unit.

Functions and Features of the TNW1PF4E8 Board

Function and Feature	Description
Basic function	The PF4E8 board can access four 2 Mbit/s optical signals and eight E1/T1 electrical signals.
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.
Port allocation	External ports: DDN-1 to DDN-12, representing twelve external ports. DDN1-DDN4: Supports I-2M optical. DDN5-DDN12: Supports eight 75/120-ohm E1 ports or eight 100-ohm T1 ports. Internal ports: The port number ranges from 65 to 78.
Overhead processing	Processes path overheads at the VC-12 level, such as J2 and V5 bytes.
Port specifications	Supports I-2M optical ports and is compatible with the C37.94 standard. NOTE: I-2M is an optical port specification defined by Huawei.
TPS	Not supported
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.
Hitless protection switching	Supported. Upstream mode: VC-12, E1
Clock	Extracts clock signals from the first channel. Electrical port: supports re-timing of the cross-connect clock and tributary clock. Electrical port: supports re-timing of the cross-connect clock. Transmits E1 clock signals transparently.
Maintenance features	Provides the following maintenance features: External ports support inloops and outloops at optical and electrical ports. Warm resets and cold resets (with warm resets having no impact on services) Board manufacturer information query External ports support the PRBS function. Hot board swapping.
2M ASON	Supported NOTE: Only supported when the TMK5UXCME/TMK5XCS/TNZ6UXCMS/TNZ5UXCMS/TNZ5XCS board is used.
Alarm and performance event monitoring	Provides alarms and events for maintenance and fault locating.
