Protection based on PON port and backbone fiber

Service configuration data only needs to be configured to the main port, no need to configure two copies

Support OLT inter-board and intra-board port combination protection pair

Switching trigger conditions: 1) branch fiber failure, 2) OLT single board failure, 3) component failure

QUESTION 14
In the 802.1Q tag header, how many digits is the VLAN ID field, and how many VLANs can be specified in total?

4;16

8;256

10;1024

12;4096

QUESTION 15
The OLT supports multiple protection switching modes for GPON lines. The ( ) technology is supported by the OLT to protect the backbone and branch optical fibers at the same time.

Type C

Type D

Type A

Type B

GPON networks use various protection mechanisms to ensure high availability and reliability. These mechanisms are classified into different types based on their scope and functionality:
* Type A :
* Protects only the trunk fiber (between the OLT and the splitter).
* Does not protect branch fibers (between the splitter and ONUs).
* Type B :
* Protects the trunk fiber but does not provide simultaneous protection for branch fibers.
* Type C :
* Provides full protection for both the trunk and branch fibers.
* Uses redundant fibers and splitters to ensure continuity in case of a failure.
* Type D :
* Not a standard GPON protection type.
Since the question specifies protection for both the backbone (trunk) and branch fibers, the correct answer is Type C .

GE, GE (PoE), Wi-Fi

GE, GE (PoE), RF

GE, GE (PoE), POTS

GE, GE (PoE)

GE (PoE): Powers the AP.
GE: Connects to PC, IP camera, and IPTV.

IPMB is an IP service processing board, used to converge and process broadband services

8 GE optical ports can be provided as uplink ports

Forward PVMB’s VoIP service, and realize IP uplink through FE/GE electrical port or GE optical port.

QUESTION 19
Which technology is used by vectoring to cancel inter-VDSL2 line crosstalk in downstream?

fdps

Canceller

Pre-coder

Postponed

* Vectoring in VDSL2 :
* Vectoring is a technology used to mitigate crosstalk (interference between adjacent copper lines) in VDSL2 systems, improving data rates and stability.
* Crosstalk occurs when signals from one line interfere with signals on another line, especially in bundled copper cables.
* Pre-coder Technology :
* Pre-coding is a key technique used in vectoring for downstream transmission.
* It works by pre-distorting the transmitted signal at the DSLAM (Digital Subscriber Line Access Multiplexer) to cancel out the expected crosstalk at the receiver (CPE).
* This ensures that the received signal at each CPE is free from interference caused by other lines.
* Other Options :
* fdps : Not a recognized term in the context of vectoring or VDSL2.
* Canceller : While cancellation is part of vectoring, the specific term “Canceller” is not used in this context.
* Postponed : This is unrelated to vectoring or crosstalk mitigation.
* Why C?
* Pre-coding is the correct technology used in vectoring to cancel downstream crosstalk in VDSL2.
Thus, the correct answer is C .

* ITU-T G.993.5 Standards for Vectoring in VDSL2 .

QUESTION 20
What are the correct descriptions of VLAN in MA5600?

The type of sub-vlan can be smart-vlan or mux-vlan

Standard VLAN can include standard Ethernet ports and service virtual ports

A mux-vlan can only contain one uplink port and service virtual port

A smart-vlan can contain multiple uplink ports and service virtual ports

QUESTION 21
When adding an ONT to the OLT, you need to:

Configure a DBA profile.

Configure an ONT service profile.

Add an ONT and bind a profile.

Configure an ONT line profile.

* Adding an ONT to the OLT :
* Adding an ONT (Optical Network Terminal) to the OLT involves several steps, but the critical step is registering the ONT and binding it to the appropriate profile.
* Key Steps :
* DBA Profile : Configures dynamic bandwidth allocation for the ONT but is not mandatory during initial registration.
* ONT Service Profile : Defines services (e.g., Internet, IPTV) but is applied after the ONT is added.
* Add ONT and Bind Profile : Registers the ONT with the OLT and binds it to a pre-configured line profile. This is the essential step for adding an ONT.
* ONT Line Profile : Configures the VLAN and service parameters but is created before adding the ONT.
* Why C?
* The most critical action when adding an ONT is to register it and bind it to a profile, ensuring it is recognized and operational within the network.
Thus, the correct answer is C .

QUESTION 22
In the EPON network, what are the management protocols running between the OLT and the ONT?

OMCI

SNMP

OAM

IGMP

QUESTION 23
Which of the following parameters are defined in an ONT line profile?

Mapping between GEM ports and data packets

GEM ports

T-CONT

Number of Ethernet ports on the ONT

ONT Line Profile Overview:
An ONT line profile defines the mapping and configuration of services for an ONU (Optical Network Unit) on the OLT.
Key Parameters:
Mapping between GEM ports and data packets: Specifies how data packets are mapped to GEM (GPON Encapsulation Method) ports for transmission.
GEM ports: Logical ports used to encapsulate and transmit data over the GPON network.
T-CONT (Transmission Containers): Allocates upstream bandwidth for different service flows.
Number of Ethernet ports on the ONT: This is a hardware attribute of the ONT and is not defined in the line profile.
Why A, B, C?
These parameters are directly related to the configuration of services and are included in the ONT line profile.
The number of Ethernet ports is unrelated to the line profile and is determined by the ONT hardware.
Thus, the correct answers are A, B, C.

QUESTION 24
Which of the following is the downstream wavelength of XGS-PON?

1490 nm

1310 nm

1577 nm

1290 nm

* XGS-PON Wavelengths :
* XGS-PON (10-Gigabit Symmetric Passive Optical Network) uses specific wavelengths for upstream and downstream transmission:
* Downstream (OLT to ONU) : 1577 nm.
* Upstream (ONU to OLT) : 1270 nm.
* Why 1577 nm?
* The ITU-T G.9807.1 standard specifies 1577 nm as the downstream wavelength for XGS-PON.
This wavelength is chosen to avoid interference with GPON, which uses 1490 nm for downstream transmission.
* Other Options :
* 1490 nm : Used for downstream transmission in GPON, not XGS-PON.
* 1310 nm : Used for upstream transmission in GPON, not XGS-PON.
* 1290 nm : Not a standard wavelength in PON technologies.
Thus, the correct answer is C .

* HCIA Huawei ACCESS Official Documentation , Chapter: XGS-PON Wavelengths.
* ITU-T G.9807.1 Standards for XGS-PON .
