One SDH optical interface board provides different optical transmitting module for different transmission distance. The board should be selected based on the distance and attenuation between nodes during networking. Thus, avoid the receiver optical power below the receiver sensitivity or overload.

In a long-haul transmission, configure the optical amplifier boards such as JBA2, JBPA and JDCU based on the transmission distance.

2.3.3  BA/DCU

Table 2-7 lists the BA/DCU and their corresponding slots.

Table 2-7 Slots of BA and DCU

Board	Slot
JBA2	All IU slots and slots DCU, STI, EOW and SIG
JBPA	All IU slots and slots DCU, STI, EOW and SIG
JDCU	All IU slots and slots DCU, STI, EOW and SIG

Normally, JBA2, JBPA and dispersion compensation unit (DCU) are used together with the long-haul optical transmitting module to support long distance transmission without regeneration. Here are the configuration requirements of the optical amplifier board:

n  The optical transmitting module with L-64.2b optical interface should work with JBA2.

n  The optical transmitting module with V-64.2b optical interface should work with JBA2, JBPA and JDCU.

n  The optical transmitting module with U-16.2b optical interface should work with JBA2 and JBPA.

2.3.4  Ethernet Board

Table 2-8 shows the Ethernet board and the corresponding slots.

2.4  Network-Level Protection Configuration Requirement

2.4.1  Protection Modes for Networking

Table 2-9 shows the protection modes for conventional transmission network.

Table 2-9 Protection modes for conventional transmission network

Networking topology	Protection mode
Ring network	SNCP, MSP
Chain network	1+1 or 1:1 linear MS protection

Table 2-10 lists the protection modes for intelligent transmission network.

Table 2-10 Protection modes for intelligent transmission network

SLA service level	Networking topology	Protection mode
Diamond	Ring or chain network	SNCP, 1+1 linear MS protection
Gold	Ring or chain network	MSP, 1:1 linear MS protection
Silver	Mesh	Re-routing protection
Bronze	Any network	No protection when fault occurs.
Iron	Any network	This kind of service (such as extra service) will be preempted by services at higher priority when the network resource is insufficient.

2.4.2  Configuration Requirement of SNCP

Table 2-11 shows the configuration requirements of SNCP.

Table 2-11 Configuration requirements of SNCP

No.	Item	Requirements
1	DNI networking	For SNCP, the master/slave nodes must be set correctly along the primary ring.
2	Protection service capacity	Maximum: 2304 SNCP services
3	Co-existing with MSP	To avoid mutual effect, set the SNCP delay time longer than 50 ms, which is the switching time of MSP.

2.4.3  Configuration Requirement of MSP Ring

Table 2-12 shows the configuration requirements of MSP ring.
