Kufotokozera Kwachidule:

Chipangizochi chimapereka mawonekedwe a 1-4* E1 , Waya wa Standard 2 ngati engineering order-waya (posankha).Imasinthasintha kwambiri.Ili ndi ntchito ya alamu.Ntchitoyi ndi yodalirika, yokhazikika, komanso yotsika mphamvu yogwiritsira ntchito mphamvu, kuphatikiza kwakukulu, kukula kochepa.


PEZANI CHITSANZO CHIMODZI CHAULERE

Mwachidule

Tsitsani

Mawonekedwe
*Kutengera kudzikonda kwa IC
* Modular wide dynamic Optical detector
*Amagwiritsa ntchito matelefoni awaya 2 (zotengera zosagwirizana ndi telefoni) zokhazikitsidwa ngati mainjiniya-waya hotline(posankha)
*Mawonekedwe a E1 amagwirizana ndi G.703, amatengera kuchira kwa wotchi ya digito komanso ukadaulo wosavuta wa loko
*Chizindikiro cha kuwala chikatayika, chimatha kuzindikira kuti chipangizo chakutali chazimitsidwa kapena ulusi walumikizidwa, ndikuwonetsa alamu ndi LED.
*Chida chakomweko chimatha kuwona momwe chida chakutali chikugwira ntchito
* Perekani kulamula mawonekedwe akutali Loop Back, chotsani kukonza mizere
* Mtunda wotumizira ndi 2-120Km popanda kusokoneza
*AC 220V, DC-48V, DC+24V ikhoza kukhala yosankha
*DC-48V/DC+24V magetsi okhala ndi ntchito yodziwikiratu polarity, ikayikidwa popanda kusiyanitsa pakati pa zabwino ndi zoyipa.
