D-Link DAS-3626 Manuale Utente
About this Guide
This guide is intended for network administrators and technical support staff using the DEV3726K VDSL2
Switch.
Switch.
Introduction
The DAS-3626 VDSL2 Switch delivers DMT 5-band IP-based VDSL2 broadband access for residential and small
business use. The switch provides up to 100 Mbps downstream and 50 Mbps upstream data transmission for
sixteen or twenty-four subscriber ports, enough bandwidth for high-speed Internet access, multimedia services,
and packet telephony services. The switch can coexist with ADSL, ISDN or POTS deployments. The switch
implements a 6-band DMT VDSL spectrum utilization that is fully compatible with, and an improvement upon the
standard band plan that pushes the downstream bit rates well beyond the ITU specification. The switches
feature dual Gigabit Ethernet ports for network uplink and trunking to another DAS-3626. The DAS-3626
includes the option of using either SFP or copper Gigabit Ethernet ports for uplinking. The switch has an internal
DSL splitter and DSLAM. Each VDSL subscriber port is paired with the various CPE options D-Link VDSL2
Home Gateways. The switch supports CPE management. The switch and CPE are managed via an out-of-band
console connection to a computer using terminal emulation software or accessed in-band via Telnet and web-
based management.
