Introduction
The Model 3101RC (see figure 1) delivers affordable ADSL/ADSL2/2+ network access for triple-play ready
ADSL service. The ADSL2+ IPDSLAM module, together with Patton’s ForeFront Access Platform, is the pre-
mier solution for fault tolerant Triple-Play enabled network deployments..

The Model 3101RC offers complete ADSL, ADSL2 and ADSL2+ support including extended range opera-
tion, and enhance speeds. Each 3101RC IPDSLAM Module includes all the intelligence necessary to function
as a complete single card IPDSLAM thereby providing unparalleled redundancy and fault tolerance in network
deployments. The Model 3101RC includes redundant 10/100/1000 Ethernet uplink ports as well as redun-
dant mid-plane connections to ensure non-stop operation.
The Model 3101RC is designed for triple-play networks where the reliable delivery of IP based voice, video
and data services depends on the QoS metrics that are assigned to the flows. Consequently, the Model 3101RC
supports the mapping of ATM CBR/UBR/VBR traffic types and cell rates to IEEE 802.1p/Q VLAN priority
classes. VLAN stacking or “Q-in-Q” is likewise supported to ensure transparent extension of subscriber VLAN
networks. In order to maximize WAN bandwidth, IGMP Snooping is supported to ensure that IP Multicast
traffic is detected and forwarded accordingly.
