This section describes the hardware features and installation of the DSLAM on the desktop or rack mount. For easier
management and control of the DSLAM, familiarize yourself with its display indicators, and ports. Front panel illustrations in this
chapter display the unit LED indicators. Before connecting any network device to the DSLAM, please read this chapter
completely.
2.1 Hardware Description
2.1.1 DSLAM Front Panel
The front panel provides a simple interface monitoring the DSLAM.
XDL-2420R Front Panel
■ Gigabit TP interface
10/100/1000BASE-T Copper, RJ-45 twisted-pair: Up to 100 meters.
■ SFP slots
1000BASE-X mini-GBIC slot, SFP (Small Factor Pluggable) transceiver module: From 550 meters to 2km (multi-mode
fiber), up to above 10/20/30/40/50/70/120 kilometers (single mode fiber).
■ Console Port
The console port is a DB9, RS-232 male serial port connector. This port is for engineering use, and you can use a straight
DB9 console cable to use it. The COM port properties is 115200, n, 8, 1.
■ xDSL and POTS interface
There are 24 VDSL2 / ADSL 2+ ports and 24 POTS ports with 2 Telco-50 / RJ21 type connectors on the front panel of
XDL-2420R. Each port has a built-in POTS splitter that helps the voice of telephone and data of network applications
transmit over the same wire without interruption.
The xDSL port supports detecting transmission rate automatically that operates in different band allocation and results in
different upstream and downstream bandwidths, and due to different telephone line quality, cross talk or extension distance
may affect actual achievable speed; you can configure individual port in built-in management interface for optimized
connectivity.
