DSL Access Concentrator
48-port ADSL/ADSL2+ Ready LIM
This Stinger
®
line interface module (LIM) supports a mix of DSL technologies that you can
adjust port by port, giving you a fast, cost-effective way to meet your customer’s changing
needs. Your options include ADSL and g.lite, along with ADSL2 and ADSL2+, which is
available with a simple software upgrade. ADSL technology provides transport speeds up to
8 Mbps downstream and 1 Mbps upstream, while ADSL2+ doubles the bandwidth used for
downstream transmission,—enabling more high-value services. You can also use lower-rate
ADSL2+ to extend your DSL service range and reach more subscribers.
