Hello, community members!
I'd like to share some informations about PDH, and how to configure E1 on Huawei RTN.
What is PDH ?
Plesiochronous Digital Hierarchy
It is a transmission protocol based on sending and receiving information in the form of the digital multiplexer (bit streams) that have the same bit rate and are derived from different clocks from different oscillators. Each will vary within tolerances of a few time periods. Hence it is called synchronous.
PDH has more than Standard
1- Europe (E).
2- America (T).
3- Japan (J).
1- Standard Europe (E) :
The data transfer rate is 2 megabits per second
E Types:
Including many versions E1,E2,E3,E4
E1 Capacity:
frame has 32 time slots
It takes 8000 frames/sec and 8 bits/byte
Date rate = 32 *8000*8 = 2.048 mbps.
E2 = 4 E1
E3 = 4 E2
E4 = 4 E3
Steps to Create one E1 on Huawei RTN.
1- First, from Microwave link Configuration determine the number of E1 that you want to configure.
2- From configuration select PDH/SDH service management then choose new.
3- Select IF board for source.
4- Select E1 board for sink.
5- Set source timeslot range and Set sink timeslot range.
