Switch Description and Function

The DHS-3224V VDSL Switch is an Ethernet-based switch capable of delivering VDSL service via installed telephone cabling. Up to 24 VDSL accounts can be managed per Switch and up to 6 Switches can be set up in a stacked group configuration. Each Switch paired with an on-site SP-24 DSL Splitter and remote CPE (1 unit per port). The splitter combines the VDSL data channels and lower frequency analog telephone services (including ISDN) and transmits the combined services to the end-users. For the VDSL subscriber, the CPE separates the data and voice channels with a built-in splitter allowing simultaneous, full-duplex VDSL and analog voice transmission. In this way, Ethernet over VDSL can overlay existing service without additional cable installation or conditioning.

The Switch functions as a conventional Ethernet switch where each port provides VDSL service to a single account. The local Ethernet-based network however, differs from standard Ethernet in two significant ways:

Cabling – The Switch provides VDSL service via existing 0.4 mm or 0.5 mm twisted-pair telephone cable.

Reach – VDSL service from the Switch to the subscriber can extend far beyond the maximum reach of standard Ethernet.

The Switch can be managed via an out-of-band console connection to a computer using terminal emulation software. The manager console may also be accessed in-band using an SNMP network manager or Telnet. Management functions will be familiar to users who have worked with Layer 2 Ethernet switches. For users not familiar with Ethernet switches and switch management, a detailed explanation of some of the important management concepts and Ethernet standards is provided in Chapter 5.
