HC-DM3620

Overview

HC-DM3620 provides full solution for non-blocking cross-connect and multiplexing, it offers 2 x Asynchronous serial port + 1 x V.35/V.24 + 2 x LAN+8 x Voice channels access over fiber or E1 (fiber or cable). Its merits include easy installation and debugging, reliable and steady performance, low power dissipation and high integration. It can be configured by CLI through NM port on the front-panel from the local PC. It also can be managed through In-band ECC channel by HCView NM software from remote PC.

Feature

256 x256 non-blocking cross-connect matrix

E1 uplink or fiber uplink user-selectable

When use fiber uplink, the E1 can also be as service, transmit transparently

Services supported: FXS, FXO, E1, V35, V24, RS-232

2 Ethernet ports, physically separated to ensure the transmission safely

CLI management supported for configuration and status monitoring

Can be remotely managed by HCView through inband ECC channel

Diagnostic capabilities including local and remote loop back and online BER test
