Features
ESDSL is enhanced SDSL, It is in accordance with Enhanced G.shdsl - standard - Annex F G.991.2.
Optional digital interface: V.35 or LAN, and it supportsN*64kbps(1<=N<=36),2496k,3392k,4672k,5568k.
Transmission distance of 24 AWG (0.5mm) leased lines were up to 1.5 km and 7.1 km.
The Ethernet up to the standard I EEE 802.3 and I EEE 802.3u, adaptive rate 10/100 Base-T.
There are many of indicator LEDs on the faceplate to display the work state and the status on the line.
Adopt high-performance line coding technique,4-PAM(64k-128k);16-PAM(192k-2304k);32-PAM(2496k-5568k)
Lower operating cost, simple operation, convenient using, and it needn’t to set up any software.
The test of analog loopback and the test of digital will be finished by the key-press which is in front of the faceplate.
Overview
ESDSL is enhanced SDSL, It is in accordance with enhanced G.shdsl - standard-Annex F G.991.2, it is developed by FPGA circuit technology, it is 2 wires high-speed Modem, the data transmission rate up to 5568Kbps, thereby satisfying the leased line users who want to meet hypervelocity rate, transmission distance of 24 AWG (0.5mm) communication lines were up to 1.5 km and 7.1 km., supports V.35 interface or Ethernet. The two Ethernets can be linked up by ESDSL with two twisted-pairs, it also extends the distance of Ethernet. ESDSL is very fit for cost-sensitive application or as a bridge extension for LAN device, because of its lower costs, simple operation, easy to use. The standard at Ethernet is I EEE 802.3 and I EEE 802.3u, adaptive rate 10/100 Base-T
