The importance of Broadband IP Access has been demonstrated by the year-after-year increase of new and innovative Internet, Voice, and Video applications. The adoption of IP gives service providers much more flexibility and efficiency than traditional networks comprised of various technologies such as frame relay, ATM, and TDM.
IP DSLAMs offer advantages over traditional technologies such as increased efficiency, faster speeds, and improved management. For example, they reduce the complexity of data format conversion, solve traffic congestion problems with high-speed, non-blocking Ethernet switching technology, and also provide a good mechanism for video multicasting applications, such as IGMP snooping. Thus, by eliminating protocol transformation over the access network, Telco operators have an alternative method to deploy a more cost effective Ethernet infrastructure from metro to core networks.
ZyXEL's IP Express IP-based DSLAMs terminate and convert ATM traffic directly into an Ethernet environment. The IP Express® family covers a wide range of Central and Remote IP DSLAMs well suited for services with different deployment scales and requirements.
6.5U IP DSLAM with DC Power
- ATM Forum TM 4.0 support
- Packet classification and Queue scheduling (SP, WRR, WFQ)
- VLAN bridging, VLAN trucking and one-to-one VLAN mapping
- IGMP snooping/proxy and 256 multicast group support
- Anti IP/MAC address spoofing
- Rule-based packet filtering
- Failover-enabled network termination
- Dual end loop test
10U IP DSLAM with DC-power
- 10U in height, the IES-3000 modular IP DSLAM shares MSC and line cards with the IES-2000. Each IES-3000 provides two slide-in slots for redundant MSC cards and 14 additional slots for numerous combinations of supported DSL line cards.
4U IP DSLAM with AC Power
- With a similar form factor to the IES-2000, the IES-2500 supports AC power (as opposed to DC power) and uses dedicated DSL (ADSL / ADSL2+) line cards. The functions and locations of the slide-in chassis slots are identical to the IES-2000.
4U IP DSLAM with DC Power
- 4U in height, the IES-2000 is a modular IP DSLAM that supports a combination of standard SHDSL and ADSL and ADSL2+ line cards. A Management and Switching Card (MSC) provides sophisticated layer 2 switching features as well as modular Fast Ethernet and Gigabit Ethernet uplink/subtending interfaces. Each IES-2000 features one slidein slot for a MSC card and 5 additional slots for any combination of supported DSL line cards.
Hardened ADSL 2+ Mini IP DSLAM
- The fastest speed with the most advanced and flexible DSL transport available, adjustable speeds for multiple service offerings down/up stream Up to 24/1.2 Mbps
- Application flexibility, with asymmetric data transport over a single copper pair (software configurable)
- Compliant with ITU, ANSI and ETSI standards
- POTS/ISDN in overlay mode
- Deployment from CO, cabinet or basement, multi-tenant units/multi-dwelling units
