Introduction to E/// link

E/// links divided into three types

1-TRAFFIC NODE 20P

•-used at nodal sites with huge traffic

•- have 20 slots + 1 slot for power .•-have 2 power sources .

•-have fan with 2 power sources .

•-compatible with Fiber STM .


10/68


2-TRAFFIC NODE 6P-used at nodal sites with medium traffic .

-have 6 slots + 1slot for power .

-have 2 power sources .

-have fan with 2 power sources .


11/68


3-COMPACT NODE-used at end point sites with low traffic .

-consists from 1 indoor card only .

-have 2 power sources .

-maximum number of E1=16E1 .


12/68

Types of protection

• Protection divided in three types

1- Protection (2+2)

- Used frequency as Vertical & Horizontal to duplicate the traffic

- Used 4 MMU cards .

- Used 4 RAU outdoor .

- Used XPIC cable to connect between Vertical & Horizontal MM

- Used waveguide cable to connect between Vertical & Horizont

RAU .

- Used for huge traffic .


13/68

Types of protection

2-Protection (1+1)

-used all frequency to transfer the traffic .

-used 2 MMU cards .

-used 2 RAU outdoor .

-less interference than (2+2) protection .


14/68

Types of protection

3-Protection (1+0)-used all frequency to transfer the traffic .

-used 1 MMU card .

-used 1 RAU outdoor .

-less secure than (1+1) protection

How to check interference between vertical & Horizontal MM

•If RX level for Vertical MMU on link = 30 db .

•We disconnect Vertical MMU from other side

•Check RX level for Vertical MMU on link 60 db there are interference betwVertical &Horizontal .

How to check interference between different links


68/68

How to check interference between different links

•Disconnect both Vertical & Horizontal MM

•Check RX level on other side .

•RX level should less than 95 db .

•If RX level more than 95 db there areinterference from another link .
