ZTE OLT System Test Procedure

OLT, which stands for Optical Line Terminal, it provides centralized control, aggregation, conversion, security, service provisioning, and troubleshooting capabilities, one tiny problem may cause massive internet subscribers offline.

Thus, in order to contribute to a better customer experience, increased satisfaction, and a reliable and robust fiber optic network environment. The thunder-link team ensures every OLT will be tested by the engineers comprehensively before delivering to customers. This article will introduce the test procedures of the ZTE OLT.


Preparation for the Testing

Software and Hardware Requirements

a) Shelves and boards are connected properly. (take C300 as an example).

b) The power supply is available, and the device is already started.

c) ZTE OLT dedicated serial cable; different brands of OLT use different serial cables. For details, please refer to the article: OLT Serial Cable Description

d) TheOMM software is installed. Such as PuTTY, SecureCRT, etc.

Testing Procedure

Configure the debugging and maintenance terminal for the serial interface.

a) Connect the console interface of the control and switching board to the serial interface of the debugging terminal (PC) by using a debugging cable.

b) On the debugging PC, run the terminal tool (take SecureCRT as an example).

c) On the SecureCRTConfiguration dialog box, select Connection

d) Select a COM port (COM3)in accordance with the cable connection on the serial interface. Set the Baud Rate to 9600

Note: The baud rate of the ZXA10 C600/C650/C620 switching and control board is 115200.


Logging In to the C300

a) In serial interface mode, run the en command and zxr10 password at the ZXAN> prompt to enter the administrator mode. The prompt changes to ZXAN#.

b) In ZXAN#mode, run the configure terminal to enter global configuration mode (ZXAN(config)#).

c) In ZXAN(config)#mode, run the following commands to get detailed device info:
