In which way Egypt isIn which way Egypt is connected to the world?connected to the world?
Egypt is connected to the world Egypt is connected to the world through the international through the international transmission projects passing transmission projects passing through it .through it .
To load our traffic to those projects To load our traffic to those projects we have we have three main connection three main connection nodesnodes . .
The system lands at 13 countries from France to Singapore through Algeria, Tunisia, Italy, Turkey, Cyprus(Southern Part), Egypt, Saudi Arabia, Djibouti, India, Sri Lanka, and Indonesia.
SEA ME WE-2, with an overall system cost of approximately 4.2 Billion French Francs, has been operational since August 1994.
The system operates at 565 Mb/s, and is a fully wet cable of 18 000 km except for the portion between Suez and Alexandria which is routed on land.
Egypt Segment Egypt Segment ( Alexandria-Suez )( Alexandria-Suez )
This is the only segment in which cable passes through land.
Alexandria is connected to Suez through Cairo.
We have Two Lines each line operates at 565Mb/s.
We have Two Routes (working – protection ).

SEA-ME-WE 3 was the first submarine cable system to feature wavelength division multiplexing .
SEA-ME-WE 3 is approximately 40,000 km long linking 40 landing points in 35 countries and 4 continents from Western Europe (including Germany, England and France) to the Far East (including Japan, China, and Singapore) and to Australia.
It operates at 2.5Gbit/s per channel .
SEA-ME-WE 3 is installing now an extension using only two wavelengths each operates at 10Gbit/s .
Egypt segment (segment 7) is the only segment which passes through land .
It connects Alexandria & Suez through Cairo passing in two routes ( as the case in SEA ME WE 2) . One route is working and the other one is protecting .

What we Have in Ramsis Station :What we Have in Ramsis Station :
In Ramsis Station we have a back to back connection on level of 10 Gbps Using KDD-SCS transmission System This Equipment used Erbium Doped Amplifier System.

NATIONAL BACKBONE :NATIONAL BACKBONE :
In National Backbone (SDH rings) we have more than 10 rings cover the whole Egypt Land. These long distance rings Monitor Managed and Control 24 hours 7 days per week from Ramsis Exchange capacities varies from 622 Mbps ( STM4 ) to 2.5 Mbps ( STM16 ).
And carry all kinds of customer traffic which maybe Voice , Data and Video …
SEA-ME-WE 3 NATIONAL :SEA-ME-WE 3 NATIONAL :
We use this project to carry our national traffic between CAIRO and ALEXANDRIA & SUEZ .
It is used to carry traffic to SADAT , KOM HAMADA and 10TH OF RAMADAN as well . As it is connected through this project to CAIRO.
The line capacity is STM-16 (2.5 Gbit capacity ).
Cairo is connected to ALEXANDRIA and SUEZ through 2 routes ( one is working & the other one is protecting ).
As shown previously . Our international traffic is loaded
through Alexandria or Suez to SEA-ME-WE 3 international .
If we have international traffic going from Cairo , we need to carry this traffic through SEA-ME-WE 3 national project to Alexandria or SUEZ then loading it to the international project .
We can load traffic to SEA-ME-WE 3 national project on the levels E1 , E3 , or DS3 .
LRE & DCME :LRE & DCME :
LRE & DCME is used for some traffic going to the international switch .
The use of LRE is that we use one E1 to carry traffic of two E1’s .

SOUTH GIZA :SOUTH GIZA : This project connects the area of
south Giza with a SDH network which includes Ramsis station .
Some villages are connected to this network through PDH connections .
The main nodes in this network is RAMSIS , RODA , BADRASHIN ,AYAT,& EL SAF.
This SDH ring will be upgraded to a line capacity of STM-16 .
While it will have an extension in BADRASHIN to be connected with HAWAMDIA with a line capacity of STM-4 .
So the SDH ring will be as follows :
