The OTU card in Figure 3-1can be replaced by ETM card according to actual situation.
• Working Principle
The OP card supervises the main optical channel.
The protection switching is carried out by the optical switch on the OP card when the
switching condition is met. The switching time is less than 50 ms.
• Switching Condition
The NMS gives the protection switching order when the OP card detects the LOS alarm
(the optical power is less than -25 dBm).
The OP and OTU card with protection function can perform 1+1 optical channel
protection in ring network on client side and line side respectively.
2. 1+1 Optical Channel Protection on Client Side Of Ring Network
The OP card implements 1+1 optical channel protection on the client side.

This sub-section describes the communication between the network management
system and access nodes from two aspects: software and hardware.
2. Software Interface
The software interfaces between the NCP card used in ZXMP M600 equipment and the
NMS include Qx, CLI and SNMP.
• Qx: the communication interface between ZXMP M600 and ZXONM E300 NMS/
NetNumenTM U31 developed by ZTE CORPORATION. It complies with TCP/IP.
• CLI: command line interface. User can use Telnet command to login the network
element and give orders in the command line interface.
• SNMP: simple network management protocol. It provides communication interfaces
between the ZXMP M600 and NMS developed by other manufacturers.
3. Hardware Interface
The access node is connected to the NMS via the Ethernet interface on the NCP card.
The identifier of Ethernet interface is ETH1 or ETH2.
ZXMP M600 V2.20 Product Description
ZTE Confidential & Proprietary 21
The Ethernet interface on the NCP card has the auto-cross-over function of interface
cable. Therefore, the ZXMP M600 can be connected to the NMS with the cross over
cable or straight cable directly to carry out the information exchange, as shown in.

CWDM Node2
CWDM Node 3
CWDM Node 4
CWDM Node 5
NMS ETH1 or ETH2 Interface
4. Communication between Nodes
The WDM equipment has no transmission channel for network management information.
Therefore, the network management information has to be combined to the client signal
through the assigned interface, and then be transmitted transparently between nodes.
The network management information of ZXMP M600 is combined to the client signal
through the AOSC or BOSC interface on the NCP card.
5. Intra-node Communication and Supervision
The communication and supervision in a node is implemented via the S interface. It is the
communication interface between the NCP card and MCUs on other cards.
• The communication and supervision between different chassis in a node is
implemented through the S interface cable. The S interface locates on the PCW card in
each chassis, adopted as a 15-pin socket.
ZXMP M600 V2.20 Product Description
22 ZTE Confidential & Proprietary
• The internal communication in the same chassis is implemented through the S
interface bus on the chassis backcard.
3.6 Alarm Output Function
ZXMP M600 provides alarm output function. It can output critical alarm, major alarm and
ring trip signals to the row-first cabinet in the equipment room. The alarm output interface
of ZXMP M600 is on the NCP card in the main CWU chassis, adopted as an RJ11 socket.
The interface identifier is ALM.

5.4.2 OADM Specifications
ZXMP M600 provides three kinds of OADM cards: OAD1, OAD2 and OAD3, which are
used in 8-channel systems to add/drop wavelengths. Notice that in 18-channel systems,
OMD cards are used to implement the adding/ dropping of wavelengths instead.
Take OAD1 card as example. The meaning of the card name is illustrated as follows:

The following explains the configuration of OTM as shown in Figure 7-3.
• PCWAS cards are used to provide –48 V DC power supply to the system.
• OTUV cards used in this OTM node are dual-path/bidirectional OTUV cards.
OTUV cards of other types can be used according to actual requirements.
• The OMD5-1 card configured in the master CWU chassis provides the 1310 nm
channel interface. In this configuration, the 1310 nm channel is used as the supervisory
channel.
• If the OMS 1+1 protection function is needed, determine the position of OP
card and corresponding optical connection according to the protection type.
If the service convergence function is needed, replace one OTUV card as shown in
Figure 7-3 with a ETM card.
2. OTM Configuration in 18-Channel System
Suppose an OTM equipment adds/drops 18 wavelengths and a CWE chassis is used.
The card configuration of the OTM equipment in the 18-channel system is shown in

7.2.2 Metro OADM Equipment (OADM)
The optical add/drop multiplexer (OADM) is used at the intermediate node to add/drop
part services and transmit the other services straight through.
1. OADM Configuration in 8-Channel System
Suppose three wavelengths should be added/dropped at the OADM node, and the CWU
chassis is adopted. The card configuration of the OADM equipment is as shown in Figure
7-7, and the optical fiber connection relationship shown in Figure 7-8.

The following explains the configuration of OADM as shown in Figure 7-7.
• Two PCWAS cards are used to provide –48 V DC power supply to the system, as
shown in Figure 7-7.
• This configuration is applicable to the case of adding/dropping three wavelengths.
As shown in Figure 7-8, A_AD1 and B_AD1 are supervisory channels, which are
connected to AOSC and BOSC interfaces on the NCP card respectively. The supervisory
channel wavelength can be 1310 nm or 1510 nm.
• If it is unnecessary to use the 1310 nm supervisory channel as an add/drop
wavelength, the channel occupied by the NCP card in the OADM equipment as shown in
Figure 7-7 can be replaced by a service add/drop channel.
• Use proper OAD card according to the number of wavelengths to be added/dropped.
Use OAD1 card to add/drop one wavelength, OAD2 card to add/drop two wavelengths
and OAD3 card to add/drop three wavelengths.
ZXMP M600 V2.20 Product Description
ZTE Confidential & Proprietary 67
• If four or five wavelengths need to be added/dropped, cascade two OAD cards. If
more than five wavelengths need to be added/dropped, cascade OMD5-1/OMD4-5
cards.
• As shown in Figure 7-8, OTUV1 is an OTUV card with protection function, which is
used to realize line-side 1+1 OCH protection in the ring network. To implement
client-side 1+1 OCH protection, OP cards are needed. Other OTUV cards can also be
used according to actual requirements.
• If the service convergence function is needed, replace one OTUV card as shown in
Figure 7-8 with a ETM card.
2. OADM Configuration in 18-Channel System
Suppose eight wavelengths are added or dropped at an 18-channel OADM node, and a
CWE chassis is adopted. In addition, the eighth wavelength is configured with 1+1 OCH
protection.
The card configuration of the OADM equipment is shown in Figure 7-9.

The following explains the configuration of OADM as shown in Figure 7-9.
• Two PCWAH cards are used to provide –48 V DC power supply to the system, as
shown in Figure 7-9.
• Each OMD4-1US card provides a 1311 nm channel interface. In this configuration
case, 1311 nm channel is used as the supervisory channel. As shown in Figure 7-10, the
1311 nm channel interfaces of both OMD4-1US cards are connected to AOSC and
BOSC interfaces on the same NCP card respectively.
• As shown in Figure 7-10, an OTUVp card is configured for the eighth wavelength.
Connect the working channel and the protection channel of the OTUV card to two OMD
cards respectively, one OMD card in east direction and the other in west direction. In this
way, the 1+1 OCH protection of the eighth wavelength is implemented.
In other cases that do not need OCH protection, it is unnecessary to connect the
input/output of OTUV card to different OMD cards.
• If the service convergence function is needed, replace one OTUV card as shown in
Figure 28 with a ETM card. Notice that OTUVp card should be replaced by ETMp card.
