OVERVIEW OF SATCOM

PHASE I :1990: Singrauli,Korba,Ramgundam,Khalgaon,Farakka

Rihand and Vindyachal were connected through Microwave to Singrauli

Technology used-Digital SCPC 2 voice channel at 64 kbps with Trunk Exchange at CC and one data channel at 64 kbps for each site.Data channel were connected to CC via minimux and Frame relay at CC

Frame relay was subsequently replaced with X.25 switch at CC

PHASE II: 1994Unchar,Anta , Talchar Super,Auriya,Gandhar KawasTechnology used MCPC VSAT -3 voice(12.8 KBPS) , one HSD(64

kbps) and one LSD(2.4kbps)

Upgradation : Singrauli was first to upgraded to MCPC in 1997

PHASE III :SRHQ,WRHQ,ERHQ,TANDA,SHIMADRI,KAYAKULAM,

FARIDABAD in 1999Trunk Exchange was installed at Murad Nagar Hub Later on other projects were connected as and when they came

up and phase one sites(Ramgundam ,Korba , Khalgaon and Farakka) were upgraded to MCPC

In year 2000 ,X.25 switch was replaced with Multiport router at Muradnagar

DAMA was added in year 2004GDAMS was integrated with WAN in 2006.
