4929-A2-ZN20-30 4929 DSLAM Installation and User’s Guide 15
INTRODUCTION
Overview
The 4900 Series DSLAMs are ADSL ITU G.992.5-compliant IP DSLAMs.
They are available with or without internal POTS splitters.
The 4900 Series DSLAMs are Ethernet based, environmentally hardened, and
small enough to fit in even crowded Remote Terminal cabinets.
The 4900 Series DSLAMs support IGMP snooping for IP Video support,
SNMP Management, Multimedia Traffic Management (MTM), enhanced
security features, and up to 24 Mbps downstream bandwidth available on
every one of its 24 DSL ports. Front loading, hot-swappable uplink module
options called Micro Interface Modules (MIMs) are available for installation
into the DSLAM. MIMs include T1/E1, 100BaseFX, 10/100BaseT, and
gigabit Ethernet for easy integration with other network elements and easy
migration as bandwidth requirements increase.
The 4900 Series DSLAMs interoperate with industry standard ADSL
modems over the local loop while preserving the benefits of a packet-based
architecture.
